IntroductionIn Austria, veterinary medicinal products (VMPs) containing penicillin G or cefoperazone are frequently used to treat dairy cows, which leads to the production of non-saleable waste milk. This study aimed to determine the loss of detectable antimicrobial activity of penicillin G and cefoperazone using a commercial ß-lactamase preparation, Antipen®.MethodsUltra-high-temperature (UHT) p…

IntroductionErosive immune-mediated polyarthritis (IMPA) carries a poor prognosis due to irreversible joint destruction and poor response to therapy. Monitoring response to therapy can be challenging as systemic markers like C-reactive protein (CRP) are nonspecific for underlying causes of inflammation and repeated joint fluid collection by arthrocentesis for cytological analysis is invasive. In …

IntroductionThis study aimed to evaluate the effects of a single-cell protein (SCP) source from Paecilomyces variotii on the apparent total tract digestibility (ATTD) of macronutrients and energy, diet palatability, fecal fermentative metabolites, and microbiota in dogs.Materials and methodsFive extruded diets containing 0, 4, 8, 12, and 16% of SCP were manufactured. To isolate the metabolizable …

Food-responsive enteropathy (FRE) is a common form of chronic inflammatory enteropathy in dogs. Its underlying molecular mechanisms remain incompletely characterized. Increasing evidence from human studies and emerging canine data suggests that bile acids (BAs) influence intestinal homeostasis and inflammation. Duodenal mucosal biopsies from dogs with FRE (n = 8) and healthy controls (n = 4) were…

IntroductionCorticosteroid-antibiotic combinations are commonly used in veterinary ophthalmic practice, yet the potential for corticosteroids to modulate antimicrobial susceptibility remains incompletely characterized. This study evaluated the in vitro effects of fluorometholone (FML) on the antimicrobial susceptibility of three major canine ocular pathogens—Staphylococcus pseudintermedius, Strep…

Mycoplasma bovis is a significant bacterial pathogen involved in the Bovine Respiratory Disease (BRD) complex. While assessing localized mucosal immunity is vital for understanding host defenses against respiratory pathogens, there is a lack of validated diagnostic assays for detecting mucosal immunoglobulins. This study aimed to evaluate the diagnostic performance of a novel multiplex ELISA plat…

Lymphoma is one of the most common neoplastic diseases in dogs, and T-cell lymphoma in particular has frequently been reported to show limited sensitivity to conventional chemotherapy from the onset of treatment when compared with B-cell lymphoma. Owing to its high-grade and aggressive clinical behavior, there is a strong need to explore novel therapeutic approaches for canine T-cell lymphoma, in…

A 6-month-old intact male Devon Rex cat was presented for a routine health evaluation prior to castration, with no apparent clinical signs. Following the incidental discovery of a caudal thoracic mass suggestive of a diaphragmatic abnormality on pre-anesthetic radiographs, computed tomography angiography was performed for further evaluation. The imaging revealed multiple congenital vascular anoma…

BackgroundExtracts derived from the walnut (Juglans regia L.) green husk exhibit a variety of biological activities. This study investigated the effects of walnut green husk polyphenol extracts (WGHPE) on fatty liver hemorrhagic syndrome (FLHS)-related indicators, antioxidant performance, and cecal microbiota modulation in laying hens.MethodsA total of 350 Hy-Line Brown laying hens aged 43 weeks …

Computed tomography (CT) is an established imaging technique for diagnosing shoulder pathology in dogs. CT images can be used to measure muscle volume, however the reliability of measuring supraspinatus and infraspinatus muscle volume on CT images in dogs is unknown. The aims of this study were to assess the intra- and inter-rater reliability of muscle volume measurements of supraspinatus and inf…

Heat stress (HS) represents a significant environmental stressor for small ruminant production occurring during summer season, which affects feed intake, physiological homeostasis, immune function, and overall performance. Nutritional strategies based on functional feed additives, including essential oils (EO), have been proposed to enhance thermotolerance and mitigate the negative effects of HS.…

BackgroundThe improper use of antibiotics in dairy farming contributes significantly to the development of antibiotic resistance (AMR), posing a global public health risk. Antimicrobial stewardship (AMS) in dairy production can reduce the spread of AMR. Smallholder dairy farmers (SHDFs) in low- and middle-income countries (LMICs) are particularly critical stakeholders in this context, given their…

IntroductionHemolysis during storage compromises the quality of canine and feline packed red blood cell (pRBC) units by shortening unit shelf-life, reducing oxygen-carrying capacity, increasing the risk of non-immune-mediated hemolytic transfusion reactions, and necessitating the discard of units when stock is limited.MethodsDonor- and unit-level determinants of percent hemolysis were investigate…

A critically endangered western lowland gorilla has given birth to a baby boy via caesarean section at Seattle's Woodland Park Zoo, in what is believed to be only the twelfth time such a procedure has been carried out on the species. Olympia, a 29-year-old gorilla weighing approximately 90kg, delivered the 5.4lb infant last month with the assistance of a combined team of human and veterinary medi…

In this episode of Curing with Sound, we speak with Ashish Ranjan, PhD, a professor of radiation oncology and director of the Veterinary Research and Oncology Clinic at the University of Texas Southwestern. Dr. Ranjan discusses how emerging focused ultrasound applications, including histotripsy and sonodynamic therapy, are being used to treat solid tumors in companion ...

Eight cases have now been confirmed in Texas as officials expand surveillance efforts, release millions of sterile flies and mobilize resources to stop the flesh-eating parasite from spreading.
