Effects of environmental factors on host-parasite interaction patterns in backyard-tethered goats of Kerala, India

The environment is the most important stratum in the epidemiological triad of a parasitic disease and any variations in the environmental factors may decide the dynamic occurrence and existence of different lifecycle stages of these parasites. The present study investigated the correlations between key biometeorological and demographical parameters with the incidence of different gastrointestinal parasites and hemoparasites among goats. Four hundred and thirty-two goats were screened for parasitic infection in a yearlong survey conducted from July 2022 to June 2023 in the Teaching Veterinary Clinical Complex, Mannuthy, Kerala, India. The weather parameters (Tmax, Tmin, RH, THI, and bright sunshine hours), air quality parameters [AQI, PM2.5, and PM10], and demographic parameters (gender and age) were recorded along with the test positivity of different categories of gastrointestinal parasites and hemoparasites in goats by routine fecal sample examination and blood smear examination, respectively. The infection level was ranked based on the severity of the infection. The mean and daily variations in biometeorological parameters were calculated and the data were statistically analyzed to figure out the pertinent correlations in host-parasite-environment interaction patterns. High levels of parasitic infections with significant month-wise variations and climate-correlated peak infection patterns were noticed. The incidence of parasites was negatively correlated to all parameters except humidity, indicating more severe parasitism during monsoon months. The significant variations in the host-parasite interaction dynamics point towards the need for detailed explorations concerning the lifecycle of each specific parasite with a focus on the possible environment-favourable and resistant lifecycle stages. Future studies may be designed from a biometeorological perspective to develop a crucial understanding of host-parasite-environment interactions in goats ensuring sustainable goat farming.

A new human opisthorchiasis outbreak in central Italy: a never-ending story.

Opisthorchis felineus is a trematode causing a foodborne infection transmitted by raw freshwater fish belonging to Cyprinidae family. Human outbreaks in Italy dated back to 2003-2011 and involved lakes of Central Italy. The aim of this study is to report epidemiological and clinical characteristics of the human opisthorchiasis outbreak occurred in Central Italy in 2022 comparing it with previous events. We report cases diagnosed from June to December 2022 in Perugia hospital thanks to serological and molecular tests and direct examination of feces. Sixty-seven individuals were traced back by epidemiological investigation. Forty-seven received a diagnosis of opisthorchiasis, of which 45 were confirmed cases and two were considered as probable cases. These 47 individuals attended a Trasimeno lakeshore restaurant in May 2022. All but 20 presented symptoms, mostly fever. Sixteen (15 confirmed and 1 probable) cases required hospitalization. Feces examination revealed Opisthorchis spp. eggs in 35/45 (78%) confirmed cases. Thirty individuals underwent to serology and molecular stool test: 5 (16.7%) results positive to the former, 1 (3.3%) to the latter while 4 (13.3%) to both. Laboratory tests, available in 28 patients, showed eosinophilia in 82.1%, increase of alanine aminotransferase, gamma-glutamyl transferase and alkaline phosphatase in 64.3%, 75% and 67.9%, respectively. Because of pharmacy shortage of praziquantel, 22 patients were treated with albendazole, of which 13 failed clearing the parasite. Opisthorchiasis still represents a challenging diagnosis, in particular for asymptomatic patients. Albendazole may lead to treatment failure. Control measures in known endemic areas should be implemented. number 27,498/23/ON, approved by Ethical Committee of Umbrian Region in 09.13.2023.

Expression of CD14+CD282+, CD14+CD284+, CD14+HLA-DR+, CD14+CD11b+ receptors and sIgA level in premature infants with K. pneumoniae

K. pneumoniae is one of the leading microorganisms causing nosocomial infections among premature newborns. The ineffectiveness of immune defense, morphofunctional immaturity, length of hospitalization and invasive procedures create the prerequisites for the implementation of the infectious process in a hospital setting. The question of the reasons for the development of infection, the etiological agent of which colonizes the intestines, remains open. Purpose of the study: to evaluate the expression of CD14+CD282+, CD14+CD284+, CD14+HLA-DR+, and CD14+CD11b+ receptors on blood monocytes and the level of sIgA in coprofiltrates in premature infants with intestinal colonization by K. pneumonia with different genetic profiles. We examined 11 children with the uge gene (group 1), 20 newborns with the uge + fim genes (group 2), and 12 children with the kfu + uge + fim genes. Microbiological examination of feces included identification and antibiotic sensitivity of microorganisms. Detection of the uge, fim and kfu genes in K. pneumoniae strains was carried out by PCR. The expression level of monocyte activation markers was determined by flow cytometry. Gestational age and anthropometric parameters did not differ between newborns. Children identified with the fim gene in combination with other genes were more often discharged home with K. pneumoniae than with the uge gene. In these children, a decrease in the level of expression of CD14+CD282+, CD14+CD284+, CD14+CD11b+, CD14+HLA-DR+ receptors at birth and upon reaching postconceptional age, and a low sIgA content in coprofiltrates during 24 days of life were recorded. Thus, a decrease in the expression of CD14+CD282+, CD14+CD284+, CD14+CD282+ and CD14+HLA-DR+ receptors by blood monocytes and insufficiency of sIgA production in the large intestine determine a long period of colonization of K. pneumoniae strains with the presence of the fim gene in combination with other genes (from 15 to 180 days), as well as the possibility of Klebsiella infection occurring in subsequent periods of the child’s life. Much more often, children with the combination of genes uge + fim and kfu + uge + fim were discharged from the hospital with a diagnosis of anemia; only in these groups of children was the development of bronchopulmonary dysplasia recorded.

Zonulin — effective biomarker for the diagnosis of intestinal lesions in patients with nonalcoholic fatty liver disease in COVID‑19

The SARS‑CoV‑2 virus mainly attacks the respiratory system, but can also affect several organs, in particular, causing gastrointestinal symptoms such as vomiting, diarrhea or abdominal pain in the early stages of the disease. Intestinal dysfunction leads to a change in intestinal microorganisms and an increase in the content of inflammatory cytokines. Liver dysfunction is also relatively common in patients with coronavirus disease 2019 (COVID19). Objective — to investigate the efficacy of zonulin in determining intestinal damage in patients with nonalcoholic fatty liver disease with COVID‑19. Materials and methods. The study included 76 patients with non‑alcoholic fatty liver disease (NAFLD) who had complaints indicating intestinal disorders during the outpatient stage of follow‑up after ­COVID‑19. From the anamnesis, it was found that all examined patients had a confirmed diagnosis of infection with SARS‑CoV‑2 virus. All patients had a mostly mild course of COVID‑19, which did not require hospitalization. Patients with NAFLD were divided into two groups depending on defecation violation: group I — 36 patients who, after an acute respiratory infection caused by the SARS‑CoV‑2 virus, developed periodic diarrhea (on average, in (38.7±5.2) days after a negative PCR result for SARS‑CoV‑2 virus); group II — 40 patients with constipation, which began to bother on average in (86.9±7.4) days after a negative PCR result. The control group included 20 practically healthy individuals. The level of zonulin was determined in blood serum and faeces by enzyme‑linked immunosorbent assay. Patients underwent faecal culture to assess the quantitative and qualitative composition of the colon microflora. Results. During the anthropometric examination, overweight and first‑degree obesity were detected more frequently in patients of both groups: overweight was diagnosed most frequently in patients of group I (38.9%) and first‑degree obesity in patients of group II (35.0%). The microbiological examination of faeces in both groups of patients revealed a decrease in the number of bifidus and lactobacilli, as well as Enterococcus and E. coli with normal enzymatic properties. In group I patients, Citrobacter and Staphylococcus were statistically significantly (p <0.05) more often detected in increased concentrations in faeces, whereas in group II patients Enterobacter, Klebsiella and Clostridium were detected (p <0.05). Significant changes were found in the analysis of zonulin levels in both serum and faeces in patients with NAFLD after COVID‑19. Serum zonulin levels in patients of group I increased 6.5‑fold, and in patients of group II—8.6‑fold (p <0.001). An increase in the concentration of zonulin in the faeces was also detected — by 7.5 and 9.7 times, respectively (p <0.001). A correlation was established between the level of zonulin in both blood serum and faeces and a decrease in the number of bifidus and lactobacilli in faeces in patients of both groups. Also, a strong correlation was found between the number of Enterobacter, Klebsiella and Clostridium and a medium intensity correlation between the number of Staphylococcus in the faeces in patients of group ІІ. In patients of group І, a correlation was found between the number of Staphylococcus and Citrobacter. The level of zonulin (both in blood serum and faeces) directly depended on changes in body mass index in the patients we examined, namely, overweight in patients of group І and obesity of the first degree in patients of group ІІ. Conclusions. In patients with NAFLD after COVID19, changes in the quantitative and qualitative composition of the colon microflora were found in the intestinal lesions, including a decrease in the number of bifidobacteria and lactobacilli, as well as an increase in the content of Staphylococcus and Citrobacter in the faeces in patients with predominant diarrhoea and Enterobacter, Klebsiella and Clostridium in patients with predominant constipation. An increase in the level of zonulin in the blood serum and faeces in patients with NAFLD after ­COVID‑19 was detected. A more pronounced deviation from the norm was found in patients of group ІІ (with complaints of constipation). A direct correlation was established between the level of zonulin in the blood serum and faeces and changes in the quantitative and qualitative composition of the colon microflora, as well as an increase in body mass index in patients with NAFLD after ­COVID‑19.

Vitamin D and gut microbiome in preterm infants

BackgroundThe incidence of vitamin D deficiency among pregnant women remains high and is associated with vitamin D deficiency in infants. In normally breastfed infants, Bifidobacteriaceae and Lactobacillaceae are known to help in maintaining immunotolerance and prevent infection. Vitamin D in the gastrointestinal tract plays a role in determining the composition and function of intestinal bacteria. Preterm infants are vulnerable to intestinal dysbiosis and sepsis due to bacterial translocation. This study aimed to determine the association between vitamin D levels and intestinal dysbiosis.MethodsIt was a cohort study conducted in the Neonatal Unit, Cipto Mangunkusumo Hospital, Tertiary hospital in Indonesia, from November 2019 to January 2021. The inclusion criteria in this study were preterm infants with a gestational age of less than 32 weeks or a birth weight of less than 1500 g. Total 25-hydroxyvitamin D (25(OH)D) levels were collected from the umbilical cords of very preterm or very low birth weight infants. A fecal examination was performed on the seventh day of life to assess intestinal bacteria using real-time PCR for four bacterial genera: Bifidobacteriaceae, Lactobacillaceae, Enterobacteriaceae, and Clostridiaceae.ResultsA total of 43 infants were included in this study. Among the subjects, 53.4% had vitamin D deficiency. There was no association identified between vitamin D deficiency and intestinal dysbiosis (RR 0.67; 95% CI (0.15–2.82), p-value = 0.531). However, the ratio of Lactobacillacecae to Enterobacteriaceae was lower in those with vitamin D deficiency.ConclusionVitamin D deficiency was not associated with dysbiosis in preterm infants. However, this study found that the ratio of Lactobacillaceae to Enterobacteriaceae in those with vitamin D deficiency was lower than in those without vitamin D deficiency. Further research is warranted to confirm this finding.

Prevalence and Degree Trematoda Infection in Dairy Cattle Friesian Holstein at Koperasi Usaha Tani Ternak Suka Makmur Pasuruan

Trematode worm infections in dairy cattle have not been widely reported in various regions in Indonesia. This study aims to determine the prevalence and degree of trematode worm infection in Friesian Holstein dairy cattle at KUTT Suka Makmur, Pasuruan. The research design used survey study and cross-sectional study. The study was conducted in July-September 2023. The number of samples taken was 100, which were selected from proportional random sampling of four sub-districts, namely Grati, Nguling, Lekok, and Lumbang, with the age ranges under a year, 1-2 years, and above 2 years. The sample were examined using the sedimentation method and Flukenfinder® method. Positive samples were further examined using the McMaster method to determine the number of worm eggs per gram of feces. The results of this study obtained a prevalence of 54% with low and moderate degrees of infection. The trematode worm species found through fecal examination were Fasciola gigantica and Paramphistomum cervi. The results of chi square statistical analysis showed that sample examination method and age were related to the prevalence of trematode worms, yet location was not related to the prevalence of trematode worms. The results of kruskal wallis statistical analysis showed that age and location influence the degree of trematode worm infection.

Fascioliasis: A Zoonotic Disease and Diagnostic Capture Using Radiological Imaging

Fascioliasis, also known as hepatic distomatosis or fasciolosis, is a zoonotic infection caused by the trematodes of Fasciola. The usual reservoir for this parasitic disease is herbivorous mammals, including humans, sheep, goats, and cattle. However, humans can contract this zoonosis infection by ingesting metacercaria, a juvenile trematode stage, which adheres to aquatic vegetation. Fascioliasis is typically present asymptomatically. However, human fascioliasis may have symptoms such as eosinophilia, abdominal discomfort, and various corroborative findings covering multiple diagnostic modalities. These diagnostic options include parasitological fecal examination, which observes the parasite in the feces; radiological imaging techniques, which envision the anatomical abnormalities created by the invasion; and serological studies, which could detect the immune response system to the infestation of the parasite. This review article aims to characterize fascioliasis in terms of zoonotic occurrence, outline the available diagnostic modalities, and highlight the specific significance of radiological imaging. This may contribute to the timely and adequate identification of the condition. This review article may contribute to forming the professional dialogue concerning fascioliasis, including its epidemiology, clinical presentation, and differential diagnostics

Development of a lateral-flow assay for rapid detection of parasitic nematodes

ObjectivesWild animals kept in enclosures are exposed to an increased risk of infection with Soil-transmitted Helminth (STH) due to high animal densities and the resulting heavy contamination of the enclosures. As regular fecal examinations are necessary to monitor and maintain health, a rapid test was developed to detect STH in wildlife. MethodThe rapid test consists of two polyclonal antibodies directed against the nematode SUMO-Protein (C- & N-term). For this study, 102 fecal samples from wild boar, fallow deer, red deer and dogs were examined. The fecal samples were defined by using the sedimentation technique and then used to evaluate the developed rapid test. ResultsThe sensitivity of the rapid test was 95.38 % with a specificity of 81.08 % and a accuracy of 90.2 %. ConclusionsAt this time, there is no commercial rapid test for the detection of STH. This rapid test can enable fast disease monitoring to make a decision in the field to save animals health. In addition, this rapid tests for the detection of parasites in wildlife can be crucial in the context of One Health to prevent the spread of disease within a system through monitoring, to preserve biodiversity and to improve global health security.

Molecular diagnosis and phylogenetic insights of Eimeria species infecting buffaloes (Bubalus bubalis) in Meghalaya's subtropical hilly region, India

Coccidiosis is an intestinal infection caused by Eimeria spp. that results in economic losses owing to morbidity and mortality in young buffalo calves. This study aimed for molecular diagnosis and phylogenetic analysis of Eimeria spp. in buffaloes of Meghalaya's sub-tropical mountainous terrain. Fresh buffaloes' fecal samples were collected from buffalo farms of Umling, Umsning and Bhoirymbong blocks, Ri Bhoi, Meghalaya and screened for Eimeria oocysts using flotation and modified McMaster methods. Fecal sample examination revealed 27.44 % (87/317) infection in buffaloes. Age wise, 64.44 % (29/45), 25.35 % (36/142) and 16.92 % (22/130) infections were recorded in <6 months, 6 months to 1 year and 1–2 year old buffaloes, respectively. Morphological characterization of Eimeria spp. revealed E. bovis (21.83 %), E. bareillyi (18.39 %), E. zuernii (11.49 %), E. ellipsoidalis (3.44 %) and mixed infection (44.82 %). Amplification of ITS-1 gene confirmed Eimeria spp. (410 bp), E. bovis (238 bp) and E. zuernii (344 bp). Phylogenetic analysis of E. bovis Umiam isolate revealed that these were closely related to the E. bovis isolate from South Korea (MH245198.1), and Turkey (KU351711.1) and distantly related to the isolates from Jammu and Kashmir (OQ103422.1) and Uttar Pradesh, Mathura (OK486542.1). E. zuernii isolate from Umiam, Meghalaya was observed to be phylogenetically close to the isolates from South Korea (MH245202.1), Japan (LC171339.1) and Turkey (KU351715.1), whereas phylogenetic divergence was observed between, E. zuernii isolate from Umiam, Meghalaya with isolates of Andhra Pradesh, Tirupati (MN601278.1) and Jammu and Kashmir (OQ103424.1). Therefore, treatment and effective control strategies should be implemented immediately to prevent spread of infection in the buffaloes.

Clinical manifestation and management of hypomagnesemia in Theileria spp. infected periparturient Malabari goats

BackgroundGrass tetany or hypomagnesemia is a metabolic syndrome causing acute neurological manifestations in periparturient ruminants grazing on rapidly grown green pastures or cereal crops with high potassium or nitrogen content and low magnesium levels. Clinical reports of naturally occurring grass tetany in goats are least described in the literature and it is considered to be a rare disease. The present study documents the clinical manifestation and management of hypomagnesemia-associated excitatory neuropathy in two Theileria spp. infected Malabari goats presented to the small ruminant medicine OP unit of the University Veterinary Hospital and Teaching Veterinary Clinical Complex, Mannuthy, Thrissur, Kerala, India. MethodsThe first goat was in the last trimester of pregnancy and was showing signs of hyperesthesia, limping, difficulty in standing, and inappetence for the last six hours. The second goat was kidded six weeks back and was showing recurrent epileptic seizures and hyporexia from the previous day. Both the goats were kept on extensive grazing from the forest areas with unidentified lush vegetation. On clinical evaluation, both the goats were showing persistent excitatory neurological signs. Fecal examination, peripheral blood smear examination, PCR screening panel for hemoparasites, Complete Blood Count, and serum levels of calcium, magnesium, and glucose were evaluated. ResultsA significant reduction in serum magnesium levels was noted in both cases along with the varied glucose levels. Theileria spp. infection was noticed in blood smear examination and confirmed by PCR. The goats responded well to the therapy using MIFEX™ and other supportive medications and showed uneventful recovery. ConclusionIt is suggested that the farmers should be vigilant enough while allowing goats to graze in unknown vegetation and prevent indiscriminate fodder intake during periods of drought. This is the first documented report of hypomagnesemic excitatory neurologic symptoms in Theileria spp. infected periparturient Malabari goats and showing response to appropriate therapy.

Survey of gastrointestinal coccidian parasites of pet birds in Tehran

ABSTRACT Birds of various families and genera comprise a notable proportion of veterinary clients in veterinary practice. Regarding the scarcity of information on avian coccidia in pet birds, this study was designed to investigate and identify the diversity of gastrointestinal coccidian protozoa in caged pet birds. Accordingly, droppings samples were collected in 2.5% potassium dichromate and examined for the presence of oocysts by wet smear and by flotation with the saturated salt solution. Detected oocysts were further morphologically specified. Special Modified Ziehl-Neelsen stain was used for the detection of Cryptosporidium spp. oocysts. Out of the 145 droppings that were collected for parasitological investigations, it was discovered that a Japanese quail (Coturnix japonica) had a Cryptosporidium sp. infection (1/145: 0.7%). Additionally, Isospora spp. was found in a common mynah and a canary (2/145: 1.4%), while Eimeria sp. was detected in a canary (1/145: 0.7%). Studied birds were clinically normal and no signs of intestinal infection were observed. The oocysts are described morphologically in detail and compared with the available data. Periodic faecal examination should be recommended for monitoring intestinal parasites in pet birds both from a public health perspective for Cryptosporidium and for avian host health in the case of non-zoonotic parasites. Additionally, the identification of parasite/host species composition will enhance our understanding of species diversity and the variety of hosts that coccidian parasites are capable of infecting.

Fasciola hepatica: Updates on egg morphology, host range, and distribution

During a survey for helminths in reindeer (Rangifer tarandus) across the Palearctic region, eggs were found in zoo reindeer feces. These were identified as eggs of Fasciola hepatica based on their morphology, morphometrics, location, and analysis of their partial sequence of ITS rDNA region. Some of the eggs had an appendage, previously unreported. Additionally, adults of F. hepatica were studied. Eggs derived from their uteri were also appendaged. Diagnostic morphological traits of F. hepatica eggs (abopercular appendage, knob, egg shell thickening, and egg shape) are discussed in this article. Three dimensional models of F. hepatica eggs were created to demonstrate the eggs features as best as possible. Since fecal examination remains gold standard in diagnosing fasciolosis in humans and animals worldwide, our findings may contribute to improved diagnostics. This research has also shown that reindeer can be a final host for F. hepatica. We also discuss whether the Novaya Zemlya archipelago might be the northernmost site of fasciolosis.

Establishing the Interrelations of the Laboratory Parameters in the Gut-Kidney Axis in Cats with Signs of Triple Phosphate Urolithiasis

Introduction. Efficient treatment of the feline urolithiasis much depends on the early diagnosis of the disease, however, the diagnostic algorithm of this type of pathology is extremely poor due to the various reasons, in particular, it does not take into account the interrelations in the gut-kidney axis. Analysis of the state of gastrointestinal tract functioning and the composition of the gut microbiota can improve the potential of diagnosing the urolithiasis, predict the risk, improve the prognosis and choose the correct treatment strategy. The aim of this publication is to establish the interrelations of the laboratory parameters in the gut-kidney axis in cats with struvite urolithiasis with the signs of cystolithiasis.Materials and Methods. The objects of the research were the outbred cats with the triple phosphate urolithiasis with the signs of cystolithiasis: 1st experimental group — females; 2nd experimental group — neutered males; the control group — clinically healthy animals of both sexes. The laboratory and clinical examinations of sick animals included: ultrasonography of abdominal organs; macroscopic and biochemical urine tests; microscopy of urine sediment and urine culture test without determination of antibiotic sensitivity; macroscopic, microscopic and simple chemical examinations of freshly excreted feces; bacteriological culture test of rectal flushes without determination of antibiotic sensitivity.Results. In the urine of cats of the experimental groups, under the activity of gram-negative microorganisms Escherichia coli (0.03±0.01×106 CFU (colony forming units) and 1.00±0.03×106 CFU) and gram-positive microorganisms Staphilococcus intermedius (1.05±0.07×106 CFU and 1.00±0.08×107 CFU) there were recorded within the microscope field of view: alkalization, development of hypersthenuria, proteinuria, hypercalciuria, hematuria, including microhematuria and leukocyturia, crystalluria. The results of coprological examinations in sick cats indicated the presence of stercobilin, well-digested muscle fibres, undigested and digested cellulose, extracellular and intracellular starch, as well as impurities of non-food origin (wool). The data of microbiological examinations of feces indicated the growth of Escherichia coli (1.00±0.05×105 CFU and 1.04±0.08×107 CFU). Along with the cystolytiasis, the acoustic shadowing of the gastrointestinal tract organs in the experimental animals revealed the hyperechogenicity of liver capsule and parenchyma and heterogeneity of the pattern.Discussion and Conclusion. The revealed character of the laboratory parameter changes in the experimental animals, such as the increase of protein and creatinine levels in urine and growth of Escherichia coli in feces, proved the existence of the pathogenetic relationship between the urogenital tract lesion caused by the gram-negative microorganisms and the gut microbiota in the gut-kidney axis. The results of our study of the sick animals’ urine indicated on the infection of the urogenital tract with the urease-producing microorganisms, which led to the alkalization of urine and formation of the infection struvite stones. Urolithiasis, in turn, had an impact on the gut microbiome due to the topographic proximity of the urogenital and gastrointestinal tracts: examination of feces in cats of the experimental group had confirmed the disorder of gastrointestinal tract functioning due to dysbiotic processes in the large intestine.

Epidemiology of Angiostrongylus vasorum and Crenosoma vulpis infection in dogs in Denmark.

This retrospective study aimed to evaluate the risk factors (age and breed group) associated with Angiostrongylus vasorum and Crenosoma vulpis infection in dogs. Faecal examinations obtained in dogs from January 2016 to December 2021 as part of routine clinical practice at two veterinary clinics in the Odsherred region of Zealand, Denmark, were included in this study. Faecal samples were analysed using the Baermann technique for nematode detection. Samples were collected from two clinics located in Northwestern Zealand, Denmark. Multinomial regression analysis, quasi-Poisson models and a generalised additive model for linearity were used to analyse the data. A total of 2,013 faecal samples were included in the study. Age was a significant risk factor for a positive Baermann, with a negative linear relationship observed (A. vasorum odds ratio: 0.80, 95% confidence interval: 0.70 to 0.91, C. vulpis odds ratio: 0.95, 95% confidence interval: 0.91 to 0.99, both nematodes: odds ratio: 0.87, 95% confidence interval: 0.77 to 0.99). Breed group analysis considering retrievers and flushing and water dog as reference group, demonstrated that sheep- and cattle dogs had a reduced risk of C. vulpis infection (odds ratio: 0.49, 95% confidence interval: 0.24 to 0.97), whereas dachshunds had an increased risk of A. vasorum infection (odds ratio: 3.28, 95% confidence interval: 1.14 to 9.47). Variations in the number of nematodes was found, with companion and toy dogs exhibiting higher numbers of C. vulpis (incidence rate ratio: 21.40, 95% confidence interval: 2.88 to 159) and sheep- and cattle dogs displaying higher numbers of A. vasorum (incidence rate ratio: 30.20, 95% confidence interval: 7.33 to 125). The prevalence rates of C. vulpis and A. vasorum were estimated at 14.50% (95% confidence interval: 13 to 16.10) and 3.40% (95% confidence interval: 2.70 to 4.30), respectively. There are significantrisk factors for nematode infection in dogs that can be considered for proper preventive care of this condition.

Employing patient-centric health education for the prevention of parasitic infections.

Soil-transmitted infections such as Ascaris lumbricoides, Hookworm, Trichuris trichiura, and Strongyloides stercoralis are common in South India. Factors such as diet, sanitation, and living conditions play a role in the prevalence of helminthic diseases. Many individuals remain asymptomatic carriers. Timely intervention is essential to prevent these infections. This is a prospective, randomized intervention study that enrolled 52 participants, excluding children, all of whom had parasitic infections. A prevalidated questionnaire was given to assess the risk factors for parasitic diseases, and fecal examinations were conducted to identify parasitic infestations. The World Health Organization's hand hygiene self-assessment framework was used to evaluate handwashing skills. Subsequent posttesting and resampling of patients allowed for score comparison, assessment of reductions in parasitic load, determination of cure rates, and monitoring of patient readmission rates. After the health education intervention, a statistically significant improvement (P < 0.01) was observed in patients' knowledge and attitudes toward parasitic infections, as shown by their posttest scores compared to their pretest scores. In addition, there were notable improvements in handwashing skills following the implementation of the handwashing educational program. This research confirms that health education is vital in promoting proper hand hygiene, reducing parasitic infections, and urging timely medical care for these conditions.

A Severe Clinical Case of Theileriosis with Terminal Wasting in Adult Cattle: A Veterinary Clinical and Pathology Case Report

This veterinary clinical and pathology case report describes a severe clinical case of theileriosis in adult cattle with prolonged recumbency and terminal wasting because of complications due to chronic theileriosis in two adult (2-year-old) Jersey-Friesian Cross. The case was referred to the large animal clinic of the University Veterinary Hospital (UVH), Faculty of Veterinary Medicine, Universiti Putra Malaysia (UPM). The animals were presented as recumbent, dull, depressed, hypothermic, dehydrated, and cachexic. There were poor responses of the patients to fluid therapy and non-steroidal anti-inflammatory treatments, and they both died within 24 hrs of clinical presentation. Haematology (complete blood count and serum biochemistry) results revealed haemoconcentration and faecal examinations were negative for liver fluke infestation and blood smear examination was positive for intraerythrocytic piroplasms of Theileria (0.01% parasitaemia). Post-mortem examination further revealed advanced cachexia, generalised serous atrophy of fat, hepatomegaly, hepatic congestion, pulmonary congestion, and pulmonary oedema. Histological findings revealed atrophy of the hepatic cord, hepatic congestion, splenic hemosiderosis, pulmonary oedema and congestion. The clinicopathological findings supported an aetiological diagnosis of a severe clinical case of Theileriosis with terminal wasting because of complications due to chronic Theileriosis infection.

SOSIALISASI PENINGKATAN DETEKSI SOIL TRANSMITTED HELMINTH (STH) MELALUI MODIFIKASI PADA LARUTAN ZnS (SULFIDA SENG) DAN NaCl (NATRIUM KLORIDA) 0,9%

Public health is a crucial aspect of disease prevention efforts. One significant health issue in many countries, including Indonesia, is Soil Transmitted Helminth (STH) infection, often caused by poor sanitation and lack of environmental cleanliness awareness. STH, typically caused by Ascaris lumbricoides, Trichuris trichiura, and hookworm, can have severe health impacts, particularly on children. Fecal examination methods, especially flotation techniques using ZnS (zinc sulfide) and 0.9% NaCl (sodium chloride) solutions, are commonly employed for STH detection. However, optimizing flotation methods in the field is essential to enhance STH detection sensitivity. This study focuses on the modification of ZnS and 0.9% NaCl solutions to improve the effectiveness of detecting STH eggs. By disseminating information on these modifications to public health practitioners, this socialization aims to enhance detection and prevention efforts for STH infections. The evaluation results show significant improvements in participants' knowledge, skills, attitudes, understanding, method application, and satisfaction, indicating the effectiveness of this socialization in promoting better STH control and prevention programs.

This study aimed to determine the prevalence of Nematoda infection in the gastrointestinal tract of cattle at Payakumbuh Cattle Market. The research was conducted in August 2020. The method used was a survey using purposive sampling. One hundred fifty-five cow dung samples were collected from the Payakumbuh Cattle Market. The fecal examination was performed using the flotation method and sedimentation method. The gastrointestinal nematode was Strongyloides sp, Ostertagia sp., and Trichuris sp. Infection with one roundworm species in 18.46% of cows and 24% of bulls. Infection with two roundworm species in 10% of cows and 20% bulls. Infection with three roundworm species in 2.3% in cows and 4% in bulls. The prevalence of three roundworm species was 0.77% in cows and not found in bulls. The rate of nematode infection in the 0-2-year-old group was 29.16%, and the &gt; two-year-old group was 33.73%. It can be concluded that the average cattle in the Payakumbuh Cattle Market are infected with gastrointestinal nematodes, and severe treatment is needed either by farmers or by involvement from the local government.

Levilactobacillus brevis SG031 modulates mood-related behaviors and attenuates stress-related sleep disturbance and autonomic dysfunction via gut microbiota modulation in Wistar–Kyoto rats

AimsThe probiotic bacterium Levilactobacillus brevis (L. brevis) has been proposed as a potential solution to manage mood disorders and alleviate stress-related sleep disturbances. However, the underlying mechanisms of its effects have not been fully elucidated. The aim of this study was to explore the impact and potential mechanisms of L. brevis SG031 supplementation on anxiety/depression-like behaviors and stress-induced changes in sleep patterns and sleep-related autonomic function. Main methodsMale Wistar–Kyoto rats were administered low, medium, or high doses of L. brevis SG031 or a vehicle for 4 weeks, followed by behavioral tests to evaluate anxiety and depression. After an additional 2 weeks of SG031 or vehicle administration, a cage-exchange paradigm was performed with 24-hour physiological signal measurements under different stress conditions. Fecal samples were collected to construct a 16S rRNA library and assess fecal short-chain fatty acids (SCFAs). Key findingsHigh-dose SG031 administration yielded reduced depression-like responses and enhanced social interaction in behavioral tests. It also exhibited a protective effect against stress-induced sleep disturbance characterized by decreased sleep time, increased awake time, and autonomic dysfunction during sleep. Fecal examination indicated that high-dose SG031 administration exerted beneficial effects on gut health by maintaining the gut microbial abundance, preserving stability of the microbial composition, and enriching the gut with SCFAs, which were associated with improvements in sleep and autonomic function. SignificanceThese findings collectively underscore the multifaceted potential of SG031 in addressing mental health and stress-related sleep challenges through the modulation of the gut microbiota.
