Chronic limb disuse during the active growth phase can induce complex secondary deformities, including paradoxical bone overgrowth. A 12-month-old neutered male Toy Poodle presented with non-weight-bearing right forelimb lameness resulting from a chronic shoulder malunion following failed stabilization of a medial luxation. Computed tomography revealed a complete nonunion of the shoulder joint wi…

BackgroundCoxiella burnetii is the causative agent of Q fever, a zoonotic infection that poses serious threats to both animal and human health, particularly in the Global South. It infects livestock such as cattle, sheep and goats including wildlife and can lead to both agricultural and economic losses.MethodsA cross-sectional study was conducted to collect blood and serum samples from aborted li…

Two adult domestic shorthair cats were evaluated for progressive neurologic deficits caused by spinal cord compression secondary to vertebral osteosarcoma, giant-cell subtype. Feline giant cell osteosarcoma represents a rare tumor type, particularly uncommon in the vertebral column. The cats showed progressive paraparesis or hemiparesis, with neuroanatomic localization to C1–C5 and T3–L3 respecti…

Transitional cell carcinoma (TCC), or urothelial carcinoma, is the most common malignant tumor of the canine urinary bladder or urethra, often causing urinary obstruction. While chemotherapy is generally considered as primary management, surgical treatments, including total or partial cystectomy, have occasionally been reported. This report describes two cases of canine urethral TCC managed with …

ObjectiveTo identify the ocular microbiota of healthy dogs and with corneal ulcers, and the sensitivity-resistance of the isolated bacteria to antibiotics.Animal studied60 dogs were included. 30 of them free of clinical or ophthalmic disease; 30 diagnosed with a corneal ulcer.ProceduresSamples for microbiological analysis were obtained by a sterile swab passed over the conjunctival sac and the co…

Diabetic kidney disease (DKD) is one of the most severe complications of diabetes. Animal models of DKD play a crucial role in elucidating disease pathogenesis, exploring therapeutic strategies, and developing pharmacological interventions. This article systematically reviews the methodologies for establishing the four main categories of DKD animal models (induced, spontaneous, genetically engine…

IntroductionThe cost of veterinary care is a significant concern for many pet owners. Despite the growing use of the internet for service-related information, there is limited research regarding the accessibility of veterinary pricing information on veterinary clinic websites.Materials and methodsTo address this gap, the present study investigated the transparency of online veterinary service pri…

IntroductionSustainable management of bioactive-rich byproducts, including pomegranate peels, is crucial to support the rise of environmentally resilient intensive camel farming. The objective of this study was to investigate the impact of pomegranate peel extract (PPE) (0, 0.5, 1, and 2 g/kg) on methane production gas production, nutrient digestibility, and predictive values in camels through in…

Vaccination is widely used to control foot-and-mouth disease (FMD), necessitating robust approaches for evaluating vaccine potency to ensure a consistent supply of effective and safe vaccines. Traditional (in vivo) potency testing methods rely on live animal models, raising ethical concerns, logistical constraints, procedural variability and significant financial costs. In vitro approaches have t…

Alveolar–interstitial syndrome (AIS) is a common ultrasonographic finding in dogs and cats with pulmonary pathology, including cardiogenic pulmonary edema, noncardiogenic pulmonary edema, pneumonia, acute respiratory distress syndrome, and pulmonary contusion. Point-of-care lung ultrasound (LUS) has emerged as a rapid, noninvasive, and repeatable diagnostic tool for identifying AIS in emergency a…

Insertion/deletion (indel) polymorphisms in the bovine PRNP gene promoter region (23 bp) and intron 1 (12 bp) influence gene expression and susceptibility to bovine spongiform encephalopathy (BSE). Conventional detection methods based on DNA sequencing are cumbersome and time-consuming. This study developed a visual detection method for these two polymorphic loci using multienzyme isothermal rapi…

Pelvic inflammatory disease (PID) is a complex multifactorial infectious disorder of the female reproductive tract, associated with severe long-term sequelae including infertility, ectopic pregnancy, and chronic pelvic pain, as well as elevated risks of endometriosis, cardiometabolic diseases, and colorectal cancer. Owing to ethical constraints on human research, animal models have become indispe…

IntroductionWeaning from artificial milk feeding represents a critical transition in intensively reared dairy lambs, involving dietary change, relocation, and social reorganization, all of which may compromise welfare, immune status, and growth performance. Melatonin, owing to its anxiolytic, antioxidant, and immuno-modulatory properties, has been proposed as a potential strategy to mitigate stre…

Brucellosis, a zoonotic disease, triggers severe inflammation and reproductive complications in both humans and animals. The standard treatment protocol relies on prolonged antibiotic courses, often combining streptomycin and doxycycline, or gentamicin and doxycycline, for a duration of six to eight weeks. However, concerns have arisen regarding the efficacy, with a notable 15% failure rate and f…

ObjectiveTo evaluate the incidence, risk factors, and prognostic impact of acute kidney injury (AKI) in dogs and cats managed with mechanical ventilation (MV).DesignRetrospective single-institution study (Jan 2015–Aug 2023).SettingUniversity teaching hospital.Animals96 animals, including 81 dogs and 15 cats, undergoing MV management.Measurements and main resultsThe incidence of AKI in this animal…

Salmonella enterica subsp. enterica serovar Dublin (Salmonella Dublin) is a host-adapted pathogen that causes severe systemic disease in cattle and presents a zoonotic risk to humans. While macrophages play a pivotal role in host defense against Salmonella they are also an intracellular niche for bacterial persistence. However, the mechanism underlying the early transcriptional response of macrop…

BackgroundAccurate detection and monitoring of the oestrous cycle in West African Dwarf (WAD) goats is indispensable for reproductive management. Vaginal cytology is commonly used, but different collection methods may vary in diagnostic efficacy, smear quality, and animal safety. This study compared the diagnostic efficacy of pipette and swab stick methods for monitoring the oestrous cycle of WAD…

IntroductionGuanidinoacetic acid (GAA), the direct precursor of creatine, has been shown to improve growth performance in monogastric animals, but its metabolic effects in ruminants remain unclear. This study examined whether dietary GAA and rumen-protected GAA (RPGAA) are associated with changes in intestinal creatine-related metabolism, portal nutrient concentrations, and hepatic IGF-1 expressi…

Methane (CH4) generated during ruminal fermentation in ruminants is a major contributor to greenhouse gas emissions and represents a substantial loss of dietary energy. Therefore, mitigating enteric CH4 emissions through safe and efficient nutritional strategies is of considerable ecological and economic significance. Coconut oil (CO) has received increasing attention due to its distinctive fatty…
