Among the most problematic resistant organisms are the extended-spectrum β-lactamase (ESBL)-producing Enterobacterales, which are resistant to the 3rd-generation cephalosporins. The purpose of this study was to determine the frequency of colonization of horses admitted to the Western College of Veterinary Medicine with resistant Escherichia coli.Animals and procedure: Rectal swabs were collected from 60 horses admitted between November 2021 and March 2022. Swabs were selectively cultured for E. coli, which was identified using standard biochemical tests. The antimicrobial susceptibility of isolates was determined, and resistant isolates were screened using PCR for the presence of ESBL.Results: Escherichia coli was isolated from all 60 horses. Although pansusceptibility was the most commonly identified phenotype, multidrug-resistant isolates possessing a CTX-M-type ESBL were recovered from 1 horse. Resistance to trimethoprim + sulfamethoxazole was the most commonly encountered resistant phenotype.Conclusion and clinical relevance: Although resistance was uncommon, the identification of ESBL-producing isolates highlighted the importance of continued surveillance to monitor the emergence of resistance in equine populations.","PeriodicalId":9429,"journal":{"name":"Canadian Veterinary Journal-revue Veterinaire Canadienne","volume":"66 4","pages":"435-439"},"PeriodicalIF":0.9,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11932359/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143762872","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Median numbers of dog contacts in the preceding 24 h, 7 d, and 14 d were 1, 3, and 4, respectively, in the social media group, and 2 for each time period in the commercial survey group. In the commercial survey group, dogs had a median of 1 type of queried contact (e.g., day care) (range: 0 to 10). In the social media group, 16% dogs had no reported contacts with any other dogs in the preceding 24 h, whereas 5.2% had no contacts in the preceding week and 3.0% had no contacts over the preceding 2 wk.Conclusion and clinical relevance: Dog contact activities are variable and influenced by many factors. Understanding this is important for disease modeling, development of infection-control interventions, and assessment of risk.","PeriodicalId":9429,"journal":{"name":"Canadian Veterinary Journal-revue Veterinaire Canadienne","volume":"66 4","pages":"417-424"},"PeriodicalIF":0.9,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11932369/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143762476","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Medical management of traumatic hepatic parenchymal emphysema in a dog.","authors":"Adrien Privat, Céline Giron, Jo-Annie Letendre","doi":"","DOIUrl":"","url":null,"abstract":"A 4-year-old intact female dachshund dog was presented in shock after a traumatic event. The dog had sustained hemoperitoneum and pulmonary contusions. Veterinary point-of-care ultrasound revealed reverberation artifacts inside the liver. Abdominal ultrasonography and computed tomography identified these as lesions of hepatic emphysema. Biochemical analysis showed marked elevation of liver enzymes. Treatments included S-adenosylmethionine and broad-spectrum antibiotics, among others. Two weeks following trauma, alanine aminotransferase was near normal and there was almost complete resolution of the hepatic lesions on abdominal ultrasonography. This case report is the first to describe the medical management and time course of parenchymal hepatic emphysema in a dog following trauma. It also focuses on the diagnosis of hepatic emphysema using various imaging modalities. Key clinical message: Hepatic parenchyma emphysema can develop following blunt abdominal trauma and appears as bright, hyperechoic foci with reverberation artifacts that can be easily observed with veterinary point-of-care ultrasonography or complete abdominal ultrasonography. Hepatic emphysema does not always require surgical treatment. Monitoring biochemical abnormalities and lesions with various imaging modalities, along with providing supportive treatments, can sometimes be sufficient.","PeriodicalId":9429,"journal":{"name":"Canadian Veterinary Journal-revue Veterinaire Canadienne","volume":"66 4","pages":"370-377"},"PeriodicalIF":0.9,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11932358/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143762719","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Captive wildlife, including Bison spp., can experience Johne's disease-related epidemiological scenarios similar to those seen in cattle. To date, there is no epidemiological information about Map in captive wood bison (Bison bison athabascae) herds. The objective of this study was to examine age, sex, and location-specific density as potential risk factors associated with Map positivity in a captive wood bison herd located in Alberta.Procedure and results: Fecal samplings were obtained from October 2021 to October 2022, DNA was extracted, and qPCR targeting IS900 and F57 followed by liquid culture confirmation was completed. Within-herd prevalence of IS900/F57 qPCR in October 2021 was 4.7%; prevalence of IS900 qPCR with culture confirmation was 6.8%. Regression analysis using 3 different outcomes based on different diagnostic approaches was employed: \"base scenario\" (positive result by fecal IS900 qPCR with culture confirmation of IS900/F57 qPCR), \"scenario 1\" (positive result by fecal IS900 qPCR with culture confirmation of IS900 qPCR), and \"scenario 2\" (positive result by fecal F57 qPCR with culture confirmation of F57 qPCR). Wood bison in the age group ≥ 6 to 9 y were more likely to be Map-positive in all scenarios. Location B (higher animal density) was significantly associated with animals being Map-positive in base scenario and scenario 1.Conclusion and clinical relevance: This study identified risk factors related to Johne's disease in a captive wood bison herd. The findings can be used to initiate more studies in both the commercial and wild wood bison herds.","PeriodicalId":9429,"journal":{"name":"Canadian Veterinary Journal-revue Veterinaire Canadienne","volume":"66 4","pages":"425-434"},"PeriodicalIF":0.9,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11932366/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143762727","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Treatment-Refractory Epilepsy Alimentary Therapy (TREAT): A canine case study.","authors":"Grace Frankel, Melissa Findlay, Leeanne Bargen","doi":"","DOIUrl":"","url":null,"abstract":"Half of all epilepsy cases in both humans and canines are identified as idiopathic. Of these cases, 30 to 40% remain treatment-refractory to antiepileptic medications. Several human and dog studies have demonstrated low-carbohydrate diets and dietary medium-chain triglyceride (MCT) supplementation are effective for seizure reduction, with some patients achieving a seizure-free status. Recent evidence suggests the gut-brain axis has an important role in the pathology of neurological disease among both humans and dogs. Altered gut microbiota may have a major role in treatment-refractory epilepsy. This case report describes a dog with treatment-refractory epilepsy experiencing cluster seizures triggered by an altered gut microbiome despite therapeutic drug concentrations of multiple agents. Consideration of an underlying gastrointestinal disorder should be investigated in patients with treatment-refractory epilepsy, despite therapeutic concentrations of several antiepileptic medications. Dietary and gastrointestinal health-promoting interventions for epilepsy should also be considered before add-on pharmacotherapy or euthanasia. For difficult epilepsy cases, we suggest exploring the role of a limited-ingredient, low-carbohydrate diet, MCT supplementation, and/or pre/probiotics to augment pharmacotherapeutic strategies. This information may be critically valuable in designing high-quality, diet-based therapies for epileptic dogs. Key clinical message: Gastrointestinal workup, dietary changes to a low-carbohydrate diet, supplementation with MCTs, and addition of pre/probiotics could be considered to augment pharmacotherapeutic strategies in treatmentrefractory epilepsy cases in dogs.","PeriodicalId":9429,"journal":{"name":"Canadian Veterinary Journal-revue Veterinaire Canadienne","volume":"66 4","pages":"378-384"},"PeriodicalIF":0.9,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11932361/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143762896","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
