Screening canine sources for novel antimicrobials reveals the circular broad-spectrum bacteriocin, caledonicin, produced by Staphylococcus caledonicus.

Antimicrobial-resistant pathogens present an ongoing threat to human and animal health, with deaths linked to antimicrobial resistance (AMR) predicted to increase annually. While the misuse and overuse of antibiotics in humans undoubtedly contribute to this escalation, antibiotic use in the veterinary field, including companion animals, also plays a contributing role. Pet owners' desire to improve the quality of life of their pets is likely to support antibiotic use in this field. Consequently, there is a need for antibiotic alternatives to treat bacterial infections. This study set out to screen for antimicrobial peptides known as bacteriocins from bacterial isolates of aerobic/microaerophilic environments of canine sources and determine their potential as antibiotic alternatives against clinically relevant pathogens. Following a laboratory-based protocol, 22 bacterial isolates were subjected to whole-genome sequencing (WGS), and a total of 14 putative novel bacteriocins were identified from both class I and II bacteriocin classes. One particular bacteriocin, herein named caledonicin, was identified via in silico analysis from a Staphylococcus caledonicus strain and partially purified for further in vitro evaluation. Caledonicin is a 64-amino acid (IAANLGVSSGTAYS MANALNNISNVATA LTIIGTFTGVGTIGSGIA ATILAILKKKGVAAAAAF) novel circular bacteriocin most closely related to enterocin_NKR-5-3B based on core peptide alignment (39.1%), with a molecular weight of 6077.1 Da. Caledonicin exhibits a broad-spectrum of activity against a range of pathogenic bacteria, including methicillin-resistant Staphylococcus aureus (MRSA), methicillin-resistant Staphylococcus pseudintermedius (MRSP), and Listeria monocytogenes; and the gut-related bacterium associated with Crohn's disease, Mediterraneibacter gnavus ATCC 29149 (previously Ruminococcus gnavus ATCC 29149). This represents the first bacteriocin screening study involving bacteria from canine sources and confirms this is a rich environment for bacteriocin-producing strains. This study also identifies and characterises the first novel bacteriocin from the staphylococcal species, Staphylococcus caledonicus.

Evaluation of Population Management Based on Trap-Neuter-Return and Trap-Neuter-Adoption Practices in a Free-Roaming Cat Colony in the Federal District, Brazil.

Overpopulation of domestic animals leads to various problems, such as the formation of feline colonies. Population management methods for these colonies have been studied previously; however, no scientific consensus has been reached. This study evaluated the use of trap-neuter-return (TNR) in a free-roaming cat colony in Brazil's Federal District. The study was conducted over 18 months and involved 157 cats that had not previously been managed. The experiment had three parts: recognition and preparation, TNR intervention, and monitoring. The results showed a 47.8% reduction in colony size. Additionally, 98.8% of the animals were sterilized. The adoption, death, disappearance, abandonment, and immigration rates were 19.7%, 14.0%, 14.0%, 7.6%, and 4.5%, respectively. The TNR experiment conducted in the proposed manner, which included detailed pre-planning, mass sterilization, active management, continuous monitoring, and educational actions, proved to be efficient and humane. However, guidelines aimed at managing animal populations, promoting adoption, preventing abandonment, and educating people about responsible pet ownership are essential for achieving sustainable results.

Unveiling food safety knowledge and practices among pet owners in Lebanon

Owning pets offers various potential health benefits; however, it can be associated with gastrointestinal illnesses due to poor food safety knowledge and practices. This study aimed to evaluate the level of food safety knowledge and practices among pet owners in Lebanon, exploring the association between their knowledge/practices and socio-demographic characteristics. The participants included 300 pet owners, representing various genders, ages, educational levels, educational backgrounds, and incomes. They completed a questionnaire of 72 food handling practices and knowledge questions related to preparation, cross-contamination, storage and hygiene. In parallel, 300 non-pet owners with comparable sociodemographic characteristics to pet owners (control group) completed the questionnaire. On average, food safety knowledge scores were 62.1 ± 14.9% and 58.7 ± 15.5% among pet and non-pet owners, respectively, and the difference was significant (p = 0.05). On the other hand, mean food safety practice scores were 41.3 ± 14.8% and 40.4 ± 15.3% among pet and non-pet owners, respectively, and the difference was not significant (p = 0.41). In the food safety knowledge part, non-pet owners who were young, high income, university graduate, and from health-related majors scored significantly (p < 0.05) higher, while among pet-owners, only participants with a university degree and from health-related majors scored significantly (p < 0.05) higher, in terms of knowledge. On the other hand, In the food safety practices part, non-pet owners who were young, high income, and university graduates scored significantly (p < 0.05) higher, while among pet-owners, only young and high-income participants scored significantly (p < 0.05) higher. These results highlight the need for ongoing educational initiatives to improve food safety practices among both pet owners in Lebanon. The study suggests that targeted educational programs should be developed, considering specific socio-demographic characteristics, to enhance overall food safety awareness and practices among the population.

Attitudes, Experience, and Self-Confidence of Veterinary and Veterinary Nursing Students in Small Animal Dentistry: A Survey Study.

Dental issues are extremely common in dogs and cats, underscoring the importance of veterinary professionals' knowledge in dentistry. Nevertheless, dental problems are currently often underdiagnosed and, consequently, undertreated. This study investigated the attitudes, experiences, and self-confidence of veterinary (V) and veterinary nursing (VN) students in their final two years of study in small animal dentistry. An online questionnaire was distributed, and responses were received from 61% of V students (n=94) and 41% of VN students (n=72). The majority of both V students (61%) and VN students (69%) expressed a desire for more education in small animal dentistry. Furthermore, a minority of V students (20%) and VN students (22%) felt adequately prepared for their first day in practice after graduation. Less than half of the students (V 44% and VN 38%) had participated in a practical dental procedure outside training sessions. Self-confidence in small animal dentistry procedures was rated on a 0-10 scale. V students exhibited the highest confidence in teeth polishing (6.1) and removing tartar with ultrasonic scalers (6.0), while VN students were most confident in recognizing common oral/dental problems (6.0) and discussing dental issues with pet owners (5.3). Extra practical training significantly increased confidence in several dental procedures (p<.005). Despite positive attitudes, a notable proportion of V and VN students feel unprepared for their first day in practice, potentially stemming from insufficient training. Addressing these gaps through clear guidelines for Day One Competence and enhanced practical training is crucial, ultimately benefiting the well-being of small animals.

Associations between abnormal sleep behavior and indoor environmental risk factors among children with a chronic cough in Wuxi, China: a cross-sectional study

BackgroundIndoor environmental factors, such as pet ownership, presence of cockroaches, mattress quality, fuel usage (gas or electricity), use of biomass for cooking and heating, exposure to tobacco smoke or household molds can significantly affect the sleep quality of children with chronic cough. However, data regarding the effects of indoor environmental conditions on sleep in this population are limited. This study aimed to assess the prevalence of abnormal sleep behaviors and to establish associations between indoor environmental factors and sleep behaviors among children with chronic cough in Wuxi, China.MethodsA cross-sectional design was employed in this study, involving children aged 3–18 years. Data on sociodemographic factors, allergies, home environmental exposures, and sleep characteristics of the participants were collected using paper-based questionnaires. The association between indoor environmental factors and sleep behaviors in children with chronic cough was analyzed using logistic regression models.ResultsThe findings demonstrated that the prevalence of chronic cough among children in Wuxi was 15.50%. The chronic cough group exhibited a significantly higher incidence of eczema, wheezing, rhinitis, food allergy, and nasosinusitis than the non-chronic cough group. In addition, children with chronic cough also tended to have a family history of sleep disorders and adenoid hypertrophy (P < 0.01). After adjusting for confounding factors, a significant association was observed between bruxism (teeth grinding) and chronic cough (sometimes: odds ratio [OR] = 1.04; confidence interval [CI] = 1.01–1.08; always: OR = 1.11; CI = 1.04–1.19; P < 0.01). Among children with chronic cough, recent home decoration was associated with sleepwalking (OR = 1.04; CI = 1.00–1.07; P < 0.05), mold exposure was associated with bruxism (OR = 1.15; CI = 1.0–1.31; P < 0.05), and carpet use at home was associated with apnea (OR = 1.09; CI = 1.02–1.17; P < 0.05), twitching during sleep (OR = 1.13; CI = 1.00–1.27; P < 0.01) and morning headache (OR = 1.14; CI = 1.05–1.23; P < 0.01).ConclusionChildren with chronic cough are more prone to some abnormal sleep behaviors than children without chronic cough. Household decoration within a year, household mold exposure, and carpet use were all significantly positively associated with abnormal sleep behaviors in children with chronic cough. Our study provides novel insights into the impact of the indoor environment on children’s sleep and the occurrence of chronic cough, offering guidance for tailored health promotion programs for families.

Who Cares? Exploring the Demographics and Proportion of People Providing Care for Community Cats in Seven Study Communities in the United States

Introduction: While several studies have evaluated the demographics of pet ownership in the US, few studies have explored the demographics and proportion of the population that feed community cats. This research examines these questions in seven geographically diverse study communities. The concept of capacity for caring is advanced as a way to quantify a community’s ability and willingness to provide for community cats. Methods: A web-based panel survey was distributed and received 6,318 responses. The survey was administered in seven different study communities as part of a larger survey. Individuals were asked a series of demographic and socioeconomic questions as well as whether they fed community cats. Results: The profile of people feeding community cats is diverse with Black and Hispanic respondents emerging as more likely to feed cats than White respondents. Results indicate that an average of 30% of people feed community cats, and that most feed three or fewer cats. Significant variation in the proportion of people feeding cats is seen across the seven study communities, perhaps driven by the number of cats in the different communities. Confirming findings of previous studies, individuals who have pets of their own are also significantly more likely to feed community cats. Conclusion: The results indicate that communities have a relatively high capacity to care for community cats. This research also adds an equity perspective to programs aimed at removal of community cats from their spaces. Cat caregivers are diverse and generally reflect their respective communities. Policymakers should consider the impact to the cats and their caregivers before implementing programs that target removal of community cats from their outdoor homes.

Dog, cat, bird, fish, and other pet ownership and mortality: Evidence from the HILDA cohort.

This study used the nationally representative prospective study of the Household, Income and Labour Dynamics in Australia (HILDA) survey cohort to examine the association of pet ownership (dog, cat, bird, fish, and others) with the risk of all-cause mortality using propensity score matching based on a wide range of factors. The study sample included 15,735 participants who completed the questionnaire on pet ownership in 2018. The HILDA survey sample was matched to the National Death Index through 2022 to assess death during the follow-up period. Statistical analysis was weighted by the inverse of the propensity score in the generalized estimating equation. During the 4-year follow-up period, 377 of 15,735 (2.4%) participants died. The odds ratios (ORs) for all-cause mortality were 0.77 (95%CI: 0.59-0.99) for dog owners compared to non-pet owners after controlling for related socio-demographic, physical, psychological, and social factors. The Sobel test showed a partial mediating effect of physical activity level on the relationship between dog ownership and all-cause mortality. Ownership of cats, birds, fish, and others showed no clear association with mortality, despite owners having similar socio-demographics characteristics to dog owners. Companionship and exercise of a pet dog may be recommended as a component of health promotion policy, and may have an important role to play in promoting health aging.

The Association Between Companion Animal Attachment and Depression: A Systematic Review

ABSTRACT There is significant literature related to companion animal attachment and depression, but to date, there has not been a systematic review of it. The aims of this systematic review were threefold: (1) to compare depression outcomes between pet and non-pet owners; (2) to identify the prevalence of how attachment is operationalized within the human–pet relationships literature, as it is defined in two distinct, divergent ways: as an attachment bond or as an attachment orientation; and (3) to review and synthesize the existing literature related to the association between pet attachment and depression. A search of five databases (Pubmed, Medline, Web of Science, Embase, and PsycInfo) was conducted in January 2024 to locate articles (journal articles, dissertations) focusing on pets, attachment, and depression or depressive symptoms that met predefined inclusion and exclusion criteria. In total, 40 studies were included in the review. Eighteen studies compared depression outcomes in pet owners and non-pet owners; of these, 14 found no significant difference in depression between the two groups, while four found that pet owners were significantly less depressed than non-pet owners. Most studies measuring attachment bond revealed a positive or non-significant relationship with depression, while the majority of studies measuring attachment orientation indicate that higher levels of secure attachment are negatively associated with depression, while higher levels of attachment insecurity are typically positively associated with depression. We conclude that the field needs more clarification regarding the definition of attachment so that meaningful conclusions regarding the impact of pet attachment on mental health can be drawn.

Pet Owners' Preferences for Quality of Life Improvements and Costs Related to Innovative Therapies in Feline Pain Associated with Osteoarthritis-A Quantitative Survey.

This research aimed to explore UK cat owners' preferences for treatments for feline osteoarthritis (OA) by exploring preferences around quality of life (QoL) improvements, safety considerations, and costs associated with hypothetical innovative pain therapies. Aspects identified in an existing conceptual framework were extracted for inclusion in exploratory interviews with cat owners (n = 3) to identify key domains that contribute to the QoL of cats. QoL descriptions for cats with OA and hypothetical product attributes were developed and validated through interviews with veterinarians (n = 3). An online survey was subsequently shared with 255 pet owners in the UK. Pet owners were presented with QoL descriptions and hypothetical product attributes to gather their preferences for QoL improvements and their willingness to pay (WTP) for (unbranded) pain therapies at various price points. Pet owners were motivated to improve their cats' QoL, which translated into WTP for therapies; specifically, pet owners valued QoL improvements in mobility, pain expression, and well-being. When presented with a product profile of the hypothetical novel monoclonal antibody (mAb) and cost, 50% of cat owners were willing to pay more for a mAb that is expected to have improved efficacy and safety when compared to a hypothetical standard of care (SoC). Significantly more pet owners preferred the mAb than the SoC when price was not presented (p < 0.01), with product efficacy and safety driving pet owners' decision-making. The majority of pet owners did not agree that taking their cats to the veterinarian once a month for their treatment would be burdensome. Cat owners in the UK are motivated to improve their cats' QoL, which translates into WTP for the efficacious treatment of pain associated with osteoarthritis. Veterinarians should offer cat owners the pain treatment they feel is best suited for improving the cat's QoL and to ensure subsequent owner-pet bond is preserved.

Correlates of lifestyle patterns among children in Singapore aged 10 years: the Growing Up in Singapore Towards healthy Outcomes (GUSTO) study

ObjectiveTo characterise lifestyle patterns (comprising dietary and movement behaviour aspects) of children in Singapore and examine the correlates of these patterns.DesignAn observational study approach was used. Children recorded their diet and activities over two weekdays and two weekend days on a validated web-based assessment, My E-Diary for Activities and Lifestyle (MEDAL). Lifestyle patterns were derived using principal component analysis, and the correlations of these with multiple known determinants organised by distal, intermediate, and proximal levels of influence were studied.SettingChildren of the Growing Up in Singapore Towards healthy Outcomes (GUSTO) cohort.ParticipantsTen-year-old children (n = 397).ResultsThree lifestyle patterns, “high snacks and processed food”, “balanced” and “mixed”, were identified. We focused on the more health-promoting “balanced” pattern, characterised by lower screen-viewing and higher consumption of fruits, vegetables, wholegrains, and dairy. Among the distal factors, girls were more adherent to the “balanced” pattern compared to boys, and children of parents with lower education levels were less adherent to this pattern. Among intermediate factors, children of mothers with higher diet quality were more adherent to the “balanced” pattern. Among the proximal factors, engagement in active transport, leisure sports, and educational activities outside of school were positively associated with the “balanced” pattern, whereas screen-viewing while travelling was negatively associated with this pattern. Having siblings, pet ownership, mother’s physical activity, parenting style, parental bonding, child’s outdoor time, and breakfast consumption were not associated with children’s lifestyle patterns.ConclusionsThese findings provide direction for future interventions by identifying vulnerable groups and contexts that should be prioritised.

Clinicopathologic findings and causes of mortality in 100 pet rabbits from the Canary Islands, Spain, 2011-2022.

The European domestic rabbit (Oryctolagus cuniculus domesticus) is commonly kept as a pet, with increasing popularity among pet owners. Despite the increasing body of information on lagomorph medicine and pathology, comprehensive published compilations of causes of mortality in pet rabbits are limited. We analyzed health disorders, pathology findings, and most probable causes of death in 100 pet rabbits submitted to the Anatomopathological Diagnostic Service of the Veterinary School of the University of Las Palmas de Gran Canaria, Canary Islands, Spain, from 2011 to 2022. We reviewed clinical data and gross and histopathologic findings to classify the various disorders into infectious (n = 39), noninfectious (n = 45), and idiopathic conditions (n = 16). Within infectious disease processes, Encephalitozoon cuniculi infection (n = 14) and rabbit hemorrhagic viral disease (n = 14) had the highest prevalence. Regarding the noninfectious conditions, perioperative mortality (n = 10), gastrointestinal syndrome (n = 7), and trauma (n = 6) were the most common clinicopathologic entities observed.

Prevalence and molecular characterization of ticks infesting dogs in Agartala, Tripura

Due to its ability to spread disease from one host to another, tick infestation is the most frequent issue pet owners’ deal with and should be taken seriously. The goal of the current study was to ascertain the prevalence of tick infestation in dogs in Agartala as well as its molecular identity and characterisation. A total of 1776 dogs of various breeds, ages, sexes, and categories were included in the study, which was conducted from March 2022 to February 2023 over the course of a calendar year. The total prevalence of ticks was reported to be 62.12%. According to study on breed, sex, age, and category, German spitz, male dogs, dogs under 1 year of age and stray dogs had the highest frequency of tick infestation. All throughout the year, tick infestations were seen, with the monsoon season seeing the highest frequency. Based on 16S rRNA gene amplification and sequence analysis, molecular identification revealed that all isolated ticks were members of the Rhipicephalus sanguineus species. Using a subset of the 16S rRNA gene, phylogenetic analysis revealed that R. sanguineus (OR244468.1) from Agartala (TrRS-PB) was part of the same clade as isolates from Kerala and Assam.

Respiratory Status in Children and Exposure to Animal Allergens-The Problem of Reverse Causality in Cross-Sectional Studies.

Some epidemiological studies suggest that early exposure to animal allergens during infancy reduces the risk of bronchial asthma in school-age children. However, the observed associations in some cases may be an effect of the study used (epidemiological observational studies, especially a cross-sectional study) and indicate reverse causality. This study aimed to determine the association between exposure to animal allergens and the prevalence of respiratory diseases, including bronchial asthma, considering the potential impact of reverse causality on the observed relationships. An analysis of data from a cross-sectional epidemiological study conducted in 2020 involving 3237 primary school students aged 7-15 years in the Silesian Province (Southern Poland) was carried out. The parents of students completed a questionnaire based on The International Study on Asthma and Allergies in Childhood (ISAAC). The relationship between the occurrence of chronic cough, wheezing, and dyspnea in the last 12 months, night waking due to dyspnea, and asthma in the presence of pets was assessed. Exposure to animal allergens was determined by answering the question, "Are there any furry or feathered animals in the home?" with three response options: "yes; they have been in the past; no" (Scenario 1). For the analyses and to reveal a potential reverse causality effect, the last two response categories regarding pet ownership were combined to form a "no" category in Scenario 2, and the first two answers were combined into a "yes" category in Scenario 3. A chi-square test was used to assess the relationship between variables, and a statistical significance level of p < 0.05 was adopted. Chronic cough affected 9.5% of children, wheezing in the last 12 months-9.2%, night waking due to dyspnea-5.8%, dyspnea in the last 12 months-4.8%, bronchial asthma-9.2%. Analysis considering the category of having or not having pets (yes vs. no) showed that bronchial asthma was statistically significantly more common in children who did not have pets at home (10.9% vs. 7.9%, p = 0.002). A similar situation was observed for wheezing in the past 12 months (10.7% vs. 8.1%; p = 0.01) and nocturnal awakening due to dyspnea (6.8% vs. 5.1%, p = 0.03). No statistically significant differences were observed for the other symptoms. Analysis by time of pet ownership (a. present; b. present but in the past; c. not present) highlighted similar relationships. Asthma (a. 7.7% vs. b. 13.4% vs. c. 7.7%; p = 0.004), wheezing in the past 12 months (a. 8.1% vs. b. 8.9% vs. c. 10.9%, p = 0.03) and night waking (a. 5.0% vs. b. 4.5% vs. c. 7.1%; p = 0.04) were more common in children without pets and those who had owned pets in the past. The highest proportion of children with asthma was in homes where pets were present in the past. Analyses indicating a relationship between a higher prevalence of asthma and some respiratory symptoms, and the absence of pets cannot be considered as a casual association. The analysis conducted did not reveal a reverse causality effect. The results of observational epidemiological studies, especially a cross-sectional study, should always be interpreted with caution, considering possible distortions and conclusions drawn.

Questionnaire Development to Assess Risk Factors for Environmental Diseases of Children in Daejeon.

Background: Allergic diseases are common in children and adolescents. It is important to assess the prevalence and risk factors of environmental diseases to implement tailored countermeasures. Methods: This questionnaire study investigated factors associated with environmental diseases in elementary school children with an environmental disease from 150 households in Daejeon Metropolitan City, South Korea in 2021. Results: The participants comprised 55.7% girls and 44.3% boys, and the mean age was 10.1 years with an even age distribution. The typical risk factors observed were the type of roads nearby, the presence of mold or stains within the residence, pet ownership, and frequency of indoor ventilation and cleaning. Notably, 73.2% of the households had an eight-lane road nearby, 40.2% reported leaks, stains, or mold within their homes during the past year, and 37.1% ventilated their homes for less than 30 min. After education on preventing and managing environmental diseases, significant changes were observed in bedding washing frequency, average ventilation duration per session, and duration of humidifier usage (p < 0.05-0.001), with improvements in lifestyle. Conclusions: Our study can be used as a reference for expanding indoor air quality control education for parents with children with an environmental disease and providing tailored environmental consultations.

Six types of loves differentially recruit reward and social cognition brain areas.

Feelings of love are among the most significant human phenomena. Love informs the formation and maintenance of pair bonds, parent-offspring attachments, and influences relationships with others and even nature. However, little is known about the neural mechanisms of love beyond romantic and maternal types. Here, we characterize the brain areas involved in love for six different objects: romantic partner, one's children, friends, strangers, pets, and nature. We used functional magnetic resonance imaging (fMRI) to measure brain activity, while we induced feelings of love using short stories. Our results show that neural activity during a feeling of love depends on its object. Interpersonal love recruited social cognition brain areas in the temporoparietal junction and midline structures significantly more than love for pets or nature. In pet owners, love for pets activated these same regions significantly more than in participants without pets. Love in closer affiliative bonds was associated with significantly stronger and more widespread activation in the brain's reward system than love for strangers, pets, or nature. We suggest that the experience of love is shaped by both biological and cultural factors, originating from fundamental neurobiological mechanisms of attachment.

Case of vector-borne coinfection in a dog

Vector-borne diseases (VBD) in dogs, such as babesiosis, ehrlichiosis, anaplasmosis, and dirofilariasis, pose a significant threat to animal health in many regions worldwide, including Ukraine. These diseases are transmitted through the bites of ectoparasites, such as ticks and mosquitoes. With increasing urbanization, climate change, and population migration, the risk of spreading these diseases is significantly heightened. This article is dedicated to the case analysis of a dog in Ukraine diagnosed with two vector-borne diseases simultaneously, focusing on the clinical manifestations and diagnostic approaches for these conditions. Currently, the prevalence of VBD in dogs in Ukraine is insufficiently studied. There are only sporadic reports of isolated pathogens, with comprehensive information needing to be included. A case of concurrent dirofilariasis and babesiosis in a dog is presented. In the spring of 2024, an 8-year-old intact male German shepherd was brought to a veterinary clinic in Kamianets-Podilskyi due to general weakness. Clinical signs included fever, vomiting, slightly pale mucous membranes, and a mild cough. Following abdominal ultrasound and blood sample collection, anti-inflammatory and antiemetic medications were prescribed. A blood smear revealed Babesia canis and treatment with imidocarb was initiated. However, after a week, the dog's condition did not improve. A repeat blood test detected live microfilariae, and the CaniV-4 test identified antibodies to D. immitis, confirming dirofilariasis. Molecular studies corroborated the diagnosis. Follow-up echocardiography and radiography did not reveal visible adult worms in the heart. The dog was treated with melarsomine and a combination of imidacloprid and moxidectin. Two months later, follow-up blood tests showed no presence of microfilariae, and all blood and biochemical parameters were within normal ranges. The dog was under continuous veterinary supervision for the following months. Overall, there is a noticeable trend in the increase of VBD among dogs in Ukraine, necessitating heightened attention from veterinary services and pet owners. Regular preventive measures, such as ectoparasite control and health monitoring, are crucial for managing the spread of these diseases.

Unleashing the Personality Divide: Resilience in Dog Owners, Neuroticism in Cat Owners

ABSTRACT Personality differences have been reported in “dog people” and “cat people” across all Big Five personality traits. Dog ownership has also been associated with reduced loneliness in people living alone during periods of prolonged isolation, which may be suggestive of higher levels of resilience in this population of pet owners. This research extends these findings by investigating the predictive power of dog vs. cat ownership on Big Five personality traits and resilience in an Australian population, after controlling for age and gender. Three hundred and twenty-one participants completed an online survey consisting of questions on demographics, pet ownership, and personality, as well as providing free-hand responses for their choice in pet. As hypothesized, dog ownership was found to positively predict resilience, while cat ownership positively predicted neuroticism. In contrast to our expectations, no other personality differences were found between pet owners. Qualitative insights suggest pet choice is driven simply by “liking” that pet (i.e., being a “dog person” or “cat person”), pet personality factors, lifestyle habits, and living situations. Findings suggest that personality factors might explain why people who choose to own dogs fare better than people who choose not to own dogs during challenging times of social isolation, which may be unrelated to the animal itself.

Applying a hierarchical Bayesian framework to reveal how fear and animal ownership drive human's valuation of and interactions with coyotes

AbstractHuman dimensions research is valuable to managing human‐wildlife interactions, especially in urban environments where such interactions are common. Survey data, which commonly contain Likert scales and questions, are useful in this field; however, these data can be difficult to analyze with formal modeling approaches. We demonstrate one approach, based on hierarchical Bayesian ordinal regression, to evaluate human‐coyote relationships in Rhode Island, USA. We implemented a survey to collect demographic and sociocultural characteristics of Rhode Island residents and information related to their knowledge of and experiences with coyotes. Our objectives were to assess how these characteristics affected respondents' valuation of and interactions (sightings and incidents) with coyotes. We analyzed 980 surveys from October to December 2020. We found that respondents who had fear of coyotes or experienced an incident between an owned animal and coyote, had the lowest valuation of coyotes. The same demographic of respondents also reported the highest sightings of and incidents with coyote. These results indicate that fearful residents, in addition to pet and livestock owners, are priority targets for disseminating information or programming about coyotes. Our analyses and findings demonstrate how Bayesian ordinal regression can provide clear and appropriate inference from survey data on how groups of people vary in their relationship with wildlife. These results are important in effectively and efficiently allocating resources towards mitigation, education, and management of human‐wildlife interactions.

Meowmy, Pawrents and Menschenwelpen ‘human puppies’: Linguistic practices of Doing Interspecies Families on German Instagram

Looking at cute animal images and videos has become a popular online pastime and animals themselves increasingly appear as actors in social media who have their own accounts and profiles from which they ‘speak’ to and ‘interact’ with us. This development goes hand in hand with a change in human-animal relations in most of Western cultures, where pets – especially cats and dogs – are more and more often seen and treated as family members while the animals we eat are rendered invisible in factory farms that are spatially detached from everyday human life. The familial relationships between humans and their pet companions are constructed by a variety of sociocultural means, one of which is language. By talking about pets as babies and children and oneself as cat or dog moms, the connection between the human and the pet is discursively established as one of kinship and intimacy rather than one of ownership and obedience. Social media have become a prolific space for performing “interspecies families” (Owens, 2015), where self-acclaimed pet parents can interact with each other and build communities of practice in which pet accounts post and engage with each other from an imagined pet perspective. This article uses a quantitative corpus-based approach to study the discursive construction of interspecies families on German-speaking Instagram. By analysing more than 20,000 posts from dog and cat accounts offering first person narratives, the article provides insights into the ways human pet owners speak about themselves and their relations with their pets from an imagined pet perspective. The analysis shows that the caption texts accompanying the posted pictures and videos are highly anthropocentric: at the centre of these short texts stands the – usually female – human pet owner. Using family terminology for both humans and other animals in these posts serves the linguistic construction of interspecies families in which pets and their human companions are held together by love and kinship ties rather than ownership.

Sustained release of stem cell secretome from nano-villi chitosan microspheres for effective treatment of atopic dermatitis

Canine atopic dermatitis (AD) arises from hypersensitive immune reactions. AD symptoms entail severe pruritus and skin inflammation, with frequent relapses. Consequently, AD patients require continuous management, imposing financial burdens and mental fatigue on pet owners. In this study, we aimed to investigate the therapeutic relevance of secretome from canine adipose tissue-derived mesenchymal stem cells (MSCs), especially after encapsulation in nano-villi chitosan microspheres (CS-MS) to expect improved efficacy. Conditioned media (CM) from MSCs significantly inhibited the proliferation of splenocytes, induced the generation of regulatory T cells, and decreased mast cell degranulation. We found that beneficial soluble factors known to reduce AD symptoms, including transforming growth factor-beta 1, were detectable after sequential concentration and lyophilization of CM. The CS-MS, developed by a phase inversion regeneration method, showed high loading and sustained release of the secretome. Local injection of secretome-loaded CS-MS (ST/SC-MS) effectively reduced clinical severity compared to groups treated with secretome. Histological analysis revealed that ST/SC-MS potently suppressed epidermal hyperplasia, immunocyte infiltration and mast cell activation in the lesion. Taken together, this study presents a novel therapeutic approach exhibiting more potent and prolonged immunoregulatory efficacy of MSC secretome for canine AD treatment.
