[Show abstract][Hide abstract] ABSTRACT: During the hunting season of 2001-02, blood and spleen samples from 59 red deer (Cervus elaphus), 77 roe deer (Capreolus capreolus), four fallow deer (Dama dama), and five chamois (Rupicapra rupicapra) were collected from nine hunting districts (n = 133) and one deer farm (n = 12) in southern Austria. Sera were tested for antibodies against bovine viral diarrhea virus (BVDV) with an enzyme-linked immunosorbent assay (ELISA) and virus neutralization tests against three BVDVs and one border disease virus strain. Reverse transcriptase polymerase chain reaction was used for detection of pestivirus-specific RNA in spleen samples. Antibodies were detected in one serum sample when using ELISA and virus neutralization tests. Results of the virus neutralization tests of this sample provided strong evidence for the exposure to the BVDV-1 genotype. The spleen samples were negative for pestivirus-specific RNA.
[Show abstract][Hide abstract] ABSTRACT: An 8-year-old female Toggenburg goat was presented with a history of reduced appetite, ruminal tympany, and abdominal enlargement of 2 weeks' duration.
The abdomen was markedly distended and contained a large amount of fluid, demonstrated using ultrasonography, along with echogenic masses on the ventral ruminal and reticular walls. The findings were confirmed at exploratory laparotomy, where together with excessive peritoneal fluid, numerous nodules were found blanketing the peritoneum. PATHOLOGICAL FINDINGS AND DIAGNOSIS: Numerous partially coalescing, white-grey nodules up to 3 cm in diameter covered the peritoneum. A biphasic mesothelioma consisting of epithelial and mesenchymal components was demonstrated by histopathology and immunohistochemistry.
Primary tumours of the peritoneum are rare and occur in many animal species. They must be differentiated from chronic granulomatous peritonitis caused by bacteria (e.g. tuberculosis or 'pearl disease'), parasites and metastatic tumours.
[Show abstract][Hide abstract] ABSTRACT: In a dairy herd of 21 cows which were on pasture during the day at the end of May 2002, four eight years old cows were suddenly inappetent and showed severe diarrhoea consisting of black discolorate feces. A few days after the onset of the disease, three affected cows exhibited neurological disorders. These cows were admitted to the IInd Medical Clinic of the University for Veterinary Medicine in Vienna. Following clinical signs were observed: circulatory weakness, anorexia, atony of the rumen, diarrhoea and in accordance with acute lead poisoning typical signs of the central nervous system. One cow died and the other two animals were euthanized. Results of blood testing were anaemia, basophil spotting of erythrocytes, increase of liver enzymes and CK, hypocalcaemia, decrease of potassium and phosphate. The cerebrospinal fluid of two cows showed increased CK-, LDH- and AST-values. The lead contents of whole blood samples were between 0.486 and 0.928 mg/kg, of liver samples 13.3 to 114.4 mg/kg, of kidney samples 172.2 to 448 mg/kg and of rumen content 59 mg/kg fresh matter. At necropsy, enteritis, liver fluke disease and severe interstitial and alveolar pulmonary emphysema were found. Pathohistologically typical ischaemic necrosis of neurons predominantly at the tips of the gyri, disseminated petechial hemorrhages and moderate diffuse neovascularisation, but no acid-fast intranucleolar inclusion bodies in the renal tubules were observed. As causative agent of the acute lead poisoning a residue on combustion, taken up by the cows on the pasture, was confirmed. The ash residue was formed by combustion of three tires which contained 450 g heavy weights of 96.5% lead for wheel balance. The lead content of the ash residue was between 2.9 and 28 g/kg dry matter.
