An 11-year-old cat presented with nasal discharge and lacrimation and was diagnosed with nasal lymphoma. Although the cat showed favorable progression after undergoing chemotherapy, CT imaging demonstrated enlarged pulmonary nodules caused by Toxoplasma gondii. Following the cessation of chemotherapy, the cat was prescribed clindamycin hydrochloride for toxoplasmosis treatment; however, the cat developed kidney lymphoma and died. No T. gondii organisms were observed in the whole body necropsy specimens. It is known that immunocompromised human patients, including those who undergo chemotherapy, are considered at risk for toxoplasmosis...

A 4-year-old, male Bernese mountain dog was evaluated for a 1-year history of right hemiparesis. Computed tomography revealed a large hypoattenuating mass severely deforming the C5 vertebral arch, invading the C6 spinal canal, and causing spinal cord compression. The signal characteristics of magnetic resonance imaging indicated a lesion composed of adipose tissue. The mass was removed via right hemilaminectomy, and histopathological examination confirmed it was an infiltrative lipoma. The compressive lesion remained unresolved, so the dog underwent a second operation, after which he regained some ambulatory function...

We investigated the effects of an injectable pimobendan solution (0.15 mg/kg) on cardiac function in healthy dogs. Fifteen dogs were divided into placebo, intravenous pimobendan injection, and subcutaneous pimobendan injection groups. In the placebo, the heart rate, systolic and end-diastolic left ventricular pressure (LVPs and LVEDP), and peak positive (max dP/dt) and negative (min dP/dt) first derivatives of the left ventricular pressure did not change for 60 min. After the intravenous pimobendan injection, LVEDP decreased significantly within 5 min, while the max dP/dt increased, and the effects continued until 60 min...

The aim of this study was to elucidate the bone metabolic status after taking colostrum in newborn calves. Fourteen neonatal calves were randomly allocated to two groups fed either unheated or heated (60°C, 30 min) colostrum three times on the first day (2 l every 10 hr; 6 l in total). Heat treatment on colostrum was to reduce the bone metabolic markers assumed as heat-sensitive. The concentrations of four bone metabolic markers (the enzymes from bone cells or the bone collagen fragments) and a bone protective protein, osteoprotegerin (OPG), were measured in the blood of calves during a week after the birth and in the colostrum...

α-defensin is a potent antimicrobial peptide secreted from intestinal mucosal epithelial cells, such as Paneth cells, and affects not only bacteria but also parasites and fungi. Recently, human eosinophils have also been shown to produce α-defensin, but no studies have been done on other animals. In this study, we attempted to detect α-defensin protein in mouse eosinophils infiltrating the intestinal mucosa during a helminth infection using Zamboni fixation and immunohistochemistry. Most of the eosinophils infiltrating the intestinal mucosa during helminth infection were positive for α-defensin...

Although Moraxella lacunata causes conjunctivitis, keratitis, endocarditis, and otolaryngitis in humans, its infection is rare in animals. We report three cases of asymptomatic pulmonary abscesses caused by M. lacunata in zoo herbivores, including two elks (Cervus canadensis) and a common eland (Taurotragus oryx). In all cases, macroscopic findings included coalescence of lung lobes and severe pulmonary abscesses filled with cheese-like materials in cysts. Microscopic findings included pneumonia characterized by marked fibrin exudates in alveolar spaces and infiltration of inflammatory cells...

In Japan the highest use of veterinary antimicrobials is in pig production. To obtain useful information to achieve the best approach to reducing this use, we analyzed the association between the level of on-farm biosecurity and animal welfare with the level of antimicrobial use as recorded on prescriptions on 38 pig farms under contract to veterinarians of the Japanese Association of Swine Veterinarians. To determine the level of welfare we recorded the risk of pre- and post-weaning deaths and the floor space available per fattening pig (m2 /head)...

The Sunda pangolin (Manis javanica) population in Southeast Asia faces threats such as poaching and deforestation. Health assessments of rescued individuals including physical examination and blood work are crucial for clinicians to determine the health status of these animals. The establishments of reference intervals of hematology and serum biochemistry are important for identifying clinical abnormalities. The objectives of our study were to establish blood reference intervals for Sunda pangolins, to determine if there are age and sex related differences in hematology and serum biochemistry, and to compare our results with those of a previous study on confiscated Sunda pangolins in Thailand...

Recently, we reported that follicle-sinus complexes (FSCs) in the muzzle skin are useful for postmortem diagnosis of rabid dogs. Here, we compared the sensitivity and specificity of detecting the viral antigen in the brain and FSCs of 226 suspected rabid dogs, and assessed whether the FSC harbored the virus genome and particles. The viral antigen was detected in 211 of 226 samples with 100% sensitivity and specificity. Viral RNA and particles were observed in the cytoplasm of Merkel cells (MCs). These results suggest that MCs are targets of virus infection and FSCs are useful material for diagnosing rabies...

The present study describes the association between inflammatory cell types and feline infectious peritonitis virus (FIPV) antigen in the brain of 4 cats diagnosed as feline infectious peritonitis (FIP). Immunohistochemically, FIPV antigens were detected in the inflammatory foci of the leptomeninges, choroid plexus and ventricles in 3 of the 4 cats. In 3 cases, inflammatory foci mainly consisted of CD204- and Iba1-positive macrophages, and the FIPV antigens were found in the macrophages. In the other case which was negative for FIPV antigen, severe inflammation predominantly consisting of CD20-positive B lymphocytes was observed in the leptomeninges and subventricles, accompanied with diffuse proliferation of gemistocytic astrocytes...
