Newcastle disease virus in poultry animals

Newcastle disease virus (family Paramyxoviridae; genus Avulavirus), poultry disease isextensively spread in Asia, Africa, USA and Canada. In literature, strains of Newcastle disease virus are worldwide reported and causing a huge loss to the poultry industries. The present review discusses about Newcastle disease virus and mentioning about its clinical trial-based studies and also discussed about surveillance-based studies and vaccination. In this literature there should be more focus area on the techniques to make a vaccination successful and make any permanent cure for it. Also, we have checked the mortality rate of different states so that we should perform our techniques in those countries. In addition, this literature includes bioinformatics approach study various strains of Newcastle disease virus

Evaluation of the trace element concentration in some livestock and poultry bone samples using X-ray fluorescence

Element concentration (ppm) in some samples of livestock and poultry animals' bones haven evaluated using X-ray fluorescence (XRF) technique. The study included evaluation of the concentration of more than 20 elements in bone samples It has focused on the impacts of freezing process on the concentration of elements The results demonstrated that the element concentrations were reduced by freezing samples. The higher effects were on the concentration of (Cr, Al, Zn, Sr, Mg, K, Ca, Cu, Fe, S, and P) for the bones of cow and sheep, and the most effects were in cow's bone samples. Maximum and minimum ratio value element concentration (cow and sheep livestock samples/ cow and sheep freezing samples) were 54.5 ± 12.2 ppm (element of Cr) and 0 ppm (element of Ba, Mn, Ti, Sn, and Rb), respectively. The results of element concentration in chicken bone samples indicated that the high element concentration was in bone samples of livestock chicken (organic) compared with the poultry chicken (fresh and freezing).

Prevalence of Blastocystis sp. in freshwater fishes, poultry, and caprine from Penang, Malaysia.

Blastocystis is an enigmatic intestinal protist of humans and many animals. There is growing interest in its potential as an enteric pathogen, and the possible role of domestic and in-contact animals as reservoirs for human infection. The purpose of this study was to determine the prevalence of Blastocystis infection in fishes, poultry, and caprine in Penang, Malaysia. A total of 353 faecal samples/intestinal contents, consisting of 123 intestinal contents from freshwater fishes, 96 intestinal contents of commercially barn-reared chickens, 84 intestinal contents of barn-reared quails, and 50 faecal samples of caprine (29 from meat goats and 21 from dairy goats) were collected. Faecal sample/intestinal content from each animal was subjected to in-vitro cultivation method using Jones' medium supplemented with 10% horse serum. The respective colonization frequencies for dairy and meat goats were 47.6% and 31.0%, whereas 26.1% was recorded for chickens and 16.7% for quails. None of the freshwater fishes were found infected with Blastocystis. The organism was most commonly seen as spherically shaped vacuolated forms and cell diameter was significantly larger in poultry than in caprine. For further studies, molecular characterization of Blastocystis in poultry and livestock animals in the study area is highly recommended.

Seroprevalence of Anti-Hepatitis E Virus Antibodies among Patients from a Tertiary Hospital from Northeast Romania.

Background and Objectives. Being an enterically transmitted pathogen with a growing prevalence in developed countries, hepatitis E virus (HEV) infection remains an underdiagnosed disease in Eastern Europe. As far as Romania is concerned, only a few studies address this issue. Our goal was to estimate the prevalence of serum anti-HEV IgA/IgM/IgG antibodies in a group of patients admitted to the Clinical Hospital for Infectious Diseases “St. Parascheva” Iasi. Materials and Methods. The cross-sectional study consisted of enrollment of 98 patients admitted to the clinic for COVID-19 over a period of three months in 2020. Results. The median age in our study was 73 years, with an equal gender ratio and with a predominance of people from the urban environment (75%). The overall HEV antibody seroprevalence was 12.2%. The main risk factors associated with HEV infection were consumption of water from unsafe sources (58.3% HEV-positive patients vs. 26.7% HEV-negative patients, p = 0.026) and improperly cooked meat (58.3% HEV-positive patients vs. 23.2% HEV-negative patients, p = 0.01). Zoonotic transmission was an important criterion in our study, with patients reporting contact with pigs, poultry, rats, or other farms animals, but no significant differences were found between HEV antibody positive and negative groups. Conclusions. The seroprevalence rate of HEV antibodies was similar to other previous reports from our area but higher than in most European countries. The fact that HEV antibodies were detected in patients without identifiable risk factors for hepatitis E is evidence of subclinical infection as a silent threat.

Responses of egg quality sustainability, sensory attributes and lipid profile of eggs and blood to different dietary oil supplementations and storage conditions

The aim of this study is to investigate the responses of egg quality, sensory attributes and lipid profile of eggs and blood serum to different combinations of dietary oil supplementations and storage conditions. Thus, laying hens aged 25 weeks were assigned to six experimental groups and fed different diets for 14 weeks. The group fed an unsupplemented diet served as control, while the other five treatment groups consumed the same basal diet supplemented with 5% corn oil, 5% linseed oil, 2% corn oil + 3% linseed oil, 3% corn oil + 2% fish oil and 3% linseed oil + 2% fish oil, respectively. After 10 weeks, 36 eggs were collected from each experimental group and divided into three sets of 12 eggs to compare the quality of fresh eggs with those obtained after 21 days of storage at 23 °C and 5 °C. In addition, 20 untrained panellists evaluated the sensory characteristics of fresh eggs. Except for shell thickness, shell percentage and shell weight per unit of surface area (SWUSA), the supplementation of oil did not affect the egg quality parameters. The eggs laid by hens fed 3% corn oil and 2% fish oil had the highest quality shells, while the eggs from the control group had the best albumen colour, flavour and general acceptance. However, only shell percentage and shape index were unaffected by storage conditions, while all other parameters were significantly lower in eggs stored at 23 °C for 21 days. Although dietary oil supplementation did not significantly improve egg quality, feeding 3% corn oil and 2% fish oil improved eggshell quality, which declined with increasing storage temperature/period. HIGHLIGHTS Dietary oils are essential components of poultry diets and animal nutrition. Sensory attributes are essential for human acceptance of animal products. Lipid profile may reflect lipid utilisation and efficiency. Different dietary oil combinations affect the eggshell quality and sensory attributes of eggs. Linseed oil enhanced the nutritional value of egg lipids and serum lipid profiles.

Should We Consider Them as a Threat? Antimicrobial Resistance, Virulence Potential and Genetic Diversity of Campylobacter spp. Isolated from Varsovian Dogs.

Campylobacteriosis seems to be a growing problem worldwide. Apart from the most common sources of numerous Campylobacter species, such as poultry and other farm animals, dogs may be an underrated reservoir of this pathogen. Our goal was to establish the frequency of occurrence, antimicrobial resistance, and detection of chosen virulence factor genes in genomes of canine Campylobacter isolates. Campylobacter isolates frequency in dogs from shelters, and private origin was 13%. All of the tested virulence factor genes were found in 28 of 31 isolates. We determined high resistance levels to the ciprofloxacin and ampicillin and moderate tetracycline resistance. For C. jejuni shelter isolates, genetic diversity was also determined using PFGE. Our results indicate that dogs may be the reservoir of potentially diverse, potentially virulent, and antimicrobial-resistant Campylobacter strains.

Linkage Between a Plant-based Diet and Visual Impairment: A Systematic Review and Meta-Analysis

ObjectivesThe purpose of this paper is to characterize the relationship between plant-based diets and specific ocular outcomes among adults. MethodsData Sources: A comprehensive literature review was performed using the databases MEDLINE, EMBASE, Cochrane, and PubMed up until December 19, 2021. Study Selection: Studies that focused on observed visual changes due to a reduced intake of animal products with a minimum of 50 eyes were eligible for inclusion. Data Extraction: Two levels of screening, quality assessment, and data extraction were conducted by two reviewers independently. The twenty-one studies identified from 814 unique studies progressed to data extraction and fifteen were included in the quantitative analysis using STATA 15.0 fixed-effect and random-effect models computed based on heterogeneity. ResultsFifteen studies (51,695 participants) assessed the impact of fish consumption, eight studies (28,753 participants) analyzed the effect of red meat intake, and three studies (7723 participants) assessed the impact of omission of skim milk, poultry, and non-meat animal products and the presence of visual deterioration as indicated by age-related macular degeneration, age-related maculopathy, or cataract development. Meta-analysis indicated regular consumption of fish (OR = 0.70; CI: [0.62–0.79]) and skim milk, poultry, and non-meat animal products (OR = 0.70; CI: [0.61–0.79]) reduced the risk of visual impairment among adults. Consumption of red meat [OR = 1.41; CI: [1.07–1.86]) may increase the risk of visual impairment. ConclusionsA pescatarian diet is associated with the most favorable visual outcomes among adults while consumption of red meat negatively impacts vision. Results suggest a need for more initiatives promoting a healthy and balanced diet. Funding SourcesNot applicable.

The normal stages of development for the California valley quail.

One challenge in avian embryology is establishing a standard developmental timetable, primarily because eggs incubated for identical durations can vary in developmental progress, even within the same species. For remedy, avian development is classified into distinct stages based on the formation of key morphological structures. Developmental stages exist for a few galliform species, but the literature is lacking a description of normal stages for California valley quail (Callipepla californica). Thus, the objective of this study was to stage and document the morphological and structural development of California valley quail. Over two laying seasons, 390 eggs were incubated at 37.8֯ C in 60% RH for ≤23 days. Eggs were opened every ≤6 hours to document embryonic development, including, blastoderm diameter, anterior angle of nostril to beak tip, and lengths of wing, tarsus, third toe, total beak, total foot, and embryo. California valley quail embryos were staged and compared to domestic chicken (Gallus gallus domesticus), the staging standard for galliformes, as well as Japanese quail (Coturnix japonica), blue-breasted quail (Synoicus chinensis) and northern bobwhite quail (Colinus virginianus). This study produced the first description of the 43 normal stages of development for California valley quail. Compared with other galliformes, the California valley quail has a different number of stages and displays developmental heterochrony in stages 1–24, and morphological and developmental differences in stages 25–hatch. The observed differences emphasize the importance of staging individual avian species instead of relying on poultry animal models or close relatives for developmental reference. This is extremely important in species-specific embryological studies that evaluate critical windows of development or evaluate the impacts of environmental change on avian development. This study also suggests that staging frequencies of ≤6 hours and egg transport protocols should be standardized for future staging studies.

Compliance to playpen usages to enhance parental supervision of under-five children in rural community of Bangladesh.

IntroductionIn Bangladesh, injury is one of the leading causes of death and morbidity in children. All children under 5 years of age are at high risk for drowning though the risks are highest when children first learn to walk and crawl while they do not understand the danger of water. The Centre for Injury Prevention and Research, Bangladesh (CIPRB) in collaboration with Johns Hopkins International Injury Research Unit (JH-IIRU) has been implementing two drowning prevention interventions, providing playpens and community day care centres (anchal), or both in three rural sub-districts of Bangladesh under Saving of Lives from Drowning (SoLiD) project in Bangladesh. In CIPRB intervention areas, wooden playpens were distributed among the children nine months to three years at household (HH) level.ObjectiveThe aim of this study was to explore and understand the acceptability and perceptions of parents towards playpen and its relevance for drowning and injury related mortality and morbidity prevention.MethodsAnchal mothers (‘anchal maa’ in Bangla) distributed 30,553 playpens and collected compliance information at the HH level using a structured questionnaire. 1600 trained anchal maas collected data via face to face interviews from May 2014 to November 2015. Playpen compliance visits were conducted periodically on the second and seventh days and every two months after delivering the playpen. Data were entered using standard data entry formats and analyzed using SPSS software version 23.ResultsParents reported that playpen is a safe place and protects children from drowning and other injuries. During compliance data collection, anchal maa founds that 71.8% of all children were using playpen and 93.7% (of 71.8%) children were playing inside the playpen while mothers were busy with their household chores like cooking, washing dishes and clothes, taking care of their poultry and domestic animals etc. 95.7% parents reported playpen is being used for keeping the child safe. On an average, the children were placed two to six times per day in a playpen. 99.1% of the children who reported using a playpen did not get any injuries (falls, cuts and bruises) while using the playpen. Satisfaction level with the playpen intervention among mothers was 90.5%. Some respondents suggested improving the playpen utilization by providing toys, adding wheels for ease of mobility, and increasing the height.ConclusionThe playpens were found to be well accepted and utilized for the children, especially when mothers were busy with their household chores.

A Bayesian network structure learning approach to identify genes associated with stress in spleens of chickens

Differences in the expression patterns of genes have been used to measure the effects of non-stress or stress conditions in poultry species. However, the list of genes identified can be extensive and they might be related to several biological systems. Therefore, the aim of this study was to identify a small set of genes closely associated with stress in a poultry animal model, the chicken (Gallus gallus), by reusing and combining data previously published together with bioinformatic analysis and Bayesian networks in a multi-step approach. Two datasets were collected from publicly available repositories and pre-processed. Bioinformatics analyses were performed to identify genes common to both datasets that showed differential expression patterns between non-stress and stress conditions. Bayesian networks were learnt using a Simulated Annealing algorithm implemented in the software Banjo. The structure of the Bayesian network consisted of 16 out of 19 genes together with the stress condition. Network structure showed CARD19 directly connected to the stress condition plus highlighted CYGB, BRAT1, and EPN3 as relevant, suggesting these genes could play a role in stress. The biological functionality of these genes is related to damage, apoptosis, and oxygen provision, and they could potentially be further explored as biomarkers of stress.

IoT Based Animal Husbandry

IoT is expanding its reach in all aspects of life while instantly adapting to our lifestyle. Its ability to transmit information real-time quick, accurate, and reliable has been advantageous to various domains. Animal husbandry has a significant contribution to the world's economy. The use of sensors for the overall welfare management of cattle and poultry animals has increased in the past few years. The constant development in IoT has created scope of opportunities in the field of animal and livestock management. The proposed system includes hardware, software and an alert system that aims to improve the health of the cattle. The growth in the applications of IoT in all aspects of our lives has an increased potential for reliably transmitting the necessary information. The use of IoT to constantly monitor the health of individual cattle reduces the farmers' work and improves the life quality of the livestock.

Nutraceutical Role of Polyphenols and Triterpenes Present in the Extracts of Fruits and Leaves of Olea europaea as Antioxidants, Anti-Infectives and Anticancer Agents on Healthy Growth.

There is currently a worldwide consensus and recognition of the undoubted health benefits of the so-called Mediterranean diet, with its intake being associated with a lower risk of mortality. The most important characteristics of this type of diet are based on the consumption of significant amounts of fruit, vegetables, legumes, and nuts, which provide, in addition to some active ingredients, fiber and a proportion of vegetable protein, together with extra virgin olive oil (EVOO) as the main sources of vegetable fat. Fish and meat from poultry and other small farm animals are the main sources of protein. One of the main components, as already mentioned, is EVOO, which is rich in monounsaturated fatty acids and to a lesser extent in polyunsaturated fatty acids. The intake of this type of nutrient also provides an important set of phytochemicals whose health potential is widely spread and agreed upon. These phytochemicals include significant amounts of anthocyanins, stilbenes, flavonoids, phenolic acids, and terpenes of varying complexities. Therefore, the inclusion in the diet of this type of molecules, with a proven healthy effect, provides an unquestionable preventive and/or curative activity on an important group of pathologies related to cardiovascular, infectious, and cancerous diseases, as well as those related to the metabolic syndrome. The aim of this review is therefore to shed light on the nutraceutical role of two of the main phytochemicals present in Olea europaea fruit and leaf extracts, polyphenols, and triterpenes, on healthy animal growth. Their immunomodulatory, anti-infective, antioxidant, anti-aging, and anti-carcinogenic capabilities show them to be potential nutraceuticals, providing healthy growth.

Natural infection ofBlastocystis ST6 among commercial quails (Coturnix coturnix) in Penang, Malaysia.

Blastocystis sp. is a unicellular, anaerobic intestinal protist regularly reported in humans and various animals worldwide. There seems to be little research on Blastocystis infection in poultry in Malaysia, and none on Blastocystis in quail specifically. In Malaysia, the consumption of quail meat and eggs is rapidly gaining popularity as a significant source of protein. It is, therefore, essential to explore the presence of Blastocystis in Malaysian quails in order to aid in the understanding of Blastocystis in this group of birds and their role in its transmission. Intestinal contents were collected from 90 commercial quails raised on two farms in Penang, Malaysia, in a multi-layer cage system with adequate farm management. Detection of Blastocystis sp. was by cultivation in modified Jones' medium supplemented with 10% horse serum. Giemsa-stained slides made from positive cultures were used for morphological studies whereas Blastocystis subtyping was conducted by using Polymerase Chain Reaction (PCR). A prevalence of 17.8% (16/90) was recorded for Blastocystis sp. in quail in this study. The most common forms detected in the in vitro culture medium were vacuolar and granular forms with cell diameters ranging from 9.09 μm to 33.33 μm. None of the quail birds screened had any visible gastrointestinal symptoms or signs. All successfully sequenced isolates were identified as Blastocystis sp. ST6, one of the potentially zoonotic subtypes of Blastocystis. This study posits that the quail birds may serve as reservoirs of zoonotic subtypes of Blastocystis. More studies are required to understand the source of Blastocystis infection to poultry under intensive care and the role of poultry animals in the transmission of Blastocystis to humans.

Biogas is one of the sustained alternative energy sources. The annual biogas potential of Bingöl province was calculated according to the data of bovine, ovine and poultry animals between 2015-2020 years which were obtained from the Turkish Statistical Institute (TSI). In addition, liquid and available manure amount, biogas potential, electrical energy and heat energy amounts were determined according to the animal data of the districts in Bingöl province for 2020. It is estimated that the biogas energy potential between 2015-2020 years with 39.02 million m3 will be the most in 2018, with 36.1 m3 the least in 2019 and 36.5 million m3 in 2020. In 2020, the biogas energy potential of the districts were found among; 263 thousand m3-12.65 million m3. It is clear that in Bingöl province in 2020 from a total number of 5694302 livestock, 865202 of which are bovine and ovine that approximately 754 thousand tons of utilizable manure, 36.5 million m3 biogas, 171.4 GWh electrical energy and 171449*106 kcal m-3 heat energy can be obtained. A facility to be established in Bingöl will enable to increase the use of renewable energy sources, decrease methane gas emissions and meet energy needs of farmers or householders.

Detection of Campylobacter coli and Campylobacter jejuni in Fecal Samples From Domestics and Livestock Employees

Background: Campylobacter jejuni and Campylobacter coli are two zoonotic pathogens that commonly colonize the digestive tract of animal sources, including poultry, dogs, cats, and other various domestic farm animals. Colonization can lead to acute bacterial gastroenteritis in humans after close contact with animals or through the consumption of contaminated food or water. Objective: The present study aimed to detect and identify these bacteria in the fecal samples of domestic and livestock employees. Materials and Methods: A total of 96 samples were collected, including 48 sheep faces and 48 livestock workers’ stool samples. DNA was extracted from the samples, and the presence of Campylobacter species was investigated by the polymerase chain reaction due to the detection of specific marker genes. Results: Based on the PCR on hippuricase gene (hipO) and aspartokinase gene (asp), C. jejuni was found in 7 (7.3%) and C. coli in 4 (4.2%) of 96 isolates. Analysis of nucleotide sequences of PCR amolicons showed the genetic similarity of isolates from a common livestock center. Conclusion: Direct animal-to-human contamination seems unlikely. However, the contamination of farm water sources and sheep products with Campylobacter species can be a potential risk to human health.

Multi-drug Resistant Escherichia Coli from Poultry: A Potential Source of Antimicrobial Resistance Spread in Poultry Farm Environment

Background: Escherichia coli is known to inhabit the gastrointestinal tract of poultry and other animals. E. coli infection can cause major economic losses in poultry production. The development of resistance to the commonly used antimicrobials in the treatment of such infection can be a setback in the poultry sector. Objective: This study was carried out to determine the antibiotic resistance profile of E. coli isolated from chickens in Imo State, Nigeria. Materials and Methods: Twelve poultry farms were selected across the 3 senatorial zones of the state using purposive random sampling. A total of 120 cloacal samples were collected from chickens using sterile swabs. The samples were streaked onto MacConkey agar (MCA) and incubated at 37o C overnight. Pink colonies on the MCA were streaked onto eosin-methylene blue agar, incubated for 24 hours at 37o C, and confirmed by indole, methyl red, Voges-Proskauer, and citrate (IMVIC) tests. Antimicrobial susceptibility test was carried out using disc diffusion technique, and the inhibition zone diameter was measured and recorded as resistant or susceptible. Results: Twenty isolates out of the 120 samples were identified as E. coli. Twenty isolates were highly resistant to 5 antibiotics out of 10 antibiotics used. Antibiotic resistance patterns were as follows: amoxicillin (AMP) (95%), cephalothin (CEP) (90%), nalidixic acid (NA) (85%), trimethoprim (SXT) (85%), cefoperazone (PEF) (80%), ampicillin (AMP) (70%) ofloxacin (OFX) (15%), ciprofloxacin (CIP) (10%), gentamicin (CN) (10%), and streptomycin (S) (10%). Sixteen resistance patterns were recorded with AMC-SXT-AMP-CEP-NA-PEF being the most prevalent. Conclusion: This study shows that multi-drug resistant E. coli strains are present in poultry farms in Imo State.

A Cage Is a Cage, Unless You Educate. Rhetoric Negatively Impacts Support for a Novel Housing System for Laying Hens Unless the Public Are Educated.

It has been proposed that terminology on commercially available eggs can impact the manner in which the eggs are discussed and ultimately consumer support. In this paper we tested if the label of ‘furnished cage’ eggs is a barrier for its support in Australia. Furthermore, we examined if educational interventions could change support and the way furnished cages were discussed. Survey participants (n = 1,157) were recruited by a stratified random sample of Australian adults. The participants were surveyed on their demographics, attitudes toward the poultry industry and animal welfare, and their egg buying behavior. Participants were randomly assigned to one of four treatment groups; two control groups and two educational groups. Participants were shown one of three videos, the control groups were shown a video with general information about chickens, the educated groups were shown one of two almost identical videos that educated them on aspects of the egg-laying industry in Australia, and the welfare implications of different housing systems including furnished systems. The only difference between the two educational videos was the name given to the furnished housing system; one group was introduced to furnished cages, the other was introduced to furnished coops. Educated participants were more likely to support furnished eggs and discuss them more positively than the control groups. When asked to discuss their support for furnished systems, control group participants exposed to the term cage were more likely to discuss the impacts of caged environments than the other treatment groups. The study suggests any negative impacts of housing system terminology can be mitigated through educational interventions.

Workshop Report: Aquatic Animal Health Education

Aquatic animals need veterinary care as any other animal species but sometimes this care is inadequately managed. The role of veterinarians in conventional farmed animal health prevention and control are undoubtedly some of the activities most commonly recognised to the veterinary profession. Although poultry, swine, beef, and other terrestrial animals have been historically considered as the main source for animal protein production, it is very important to highlight that nowadays, fisheries and aquaculture represent a substantial sources of animal protein for human consumption. Global fisheries have reached a non-sustainable breakpoint and, in this scenario, aquaculture emerges as the sustainable alternative for animal protein production for the future. Animal health and welfare, and particularly the control of impact of the diseases in finfish, crustacean and mollusc farming still represents a very important challenge for aquatic animal veterinarians. The ornamental fish sector is also a relevant area, and untapped resource for aquatic animal professionals. However, these needs are not followed by the same level of veterinary services required, indicating that there is still a lot of work to be done in this direction. Disease control and prevention, and aquatic animal health promotion across these different areas is a very challenging task for the future, and represent a tremendous source of opportunity for aquatic veterinarians.

A Meta-Analysis of the Prevalence of Toxoplasmosis in Livestock and Poultry Worldwide.

Toxoplasma gondii causes toxoplasmosis with a global prevalence in the world. A large proportion of human illness is most frequently associated with consuming raw and undercooked meat or other animal products containing infective parasitic stages of T. gondii. This systematic review and meta-analysis study evaluated the prevalence of toxoplasmosis in cattle, sheep, camels, goats, and poultry worldwide. The search was performed in databases including PubMed, WoS, Scopus, Science Direct, Google Scholar, and ISC from 2000 to 2019 in Persian and English. The main inclusion criteria were the prevalence of toxoplasmosis among livestock and poultry and the prevalence indices by sample size. During these 20 years, the overall prevalence of toxoplasmosis in livestock and poultry was 28.3% (95% confidence interval (CI) 25–31.9%) using the random-effects meta-analysis model. The highest prevalence of T. gondii in livestock and poultry animals was found in Asia in 2014 with 89.8% (95% CI 78.5–95.5%). The lowest prevalence was found in Asia in 2013 with 1.26% (95% CI 0.4–3.8%). A quarter of livestock and poultry were infected with T. gondii. Since livestock products are globally important sources of people's diet, our findings are useful for policymakers to control T. gondii infection in livestock.Supplementary InformationThe online version contains supplementary material available at 10.1007/s10393-022-01575-x.
