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. 相似文献

Ronidazol is often used in racing pigeons for the treatment of Trichomonas infections and diseases. Therefore, in this study, the compatibility of the drug was examined by oral application over 7 days. For this purpose a randomized blind study was performed using four different groups (control group, 10 mg = therapy-group, 20 mg = double-dose-group and 40 mg = high-dose-group) of pigeons (Columba livia f. domestica) with 6 male and 6 female birds each. All birds were clinically healthy and between 6 and 12 weeks of age. The application of ronidazol at a dose of 10 mg/racing pigeon did show no side-effect within the duration of the study, e.g. no influence could be seen on clinical, haematological, blood-chemical and pathological parameters. Low-to middle-grade clinical alterations of the gastro-intestinal tract occurred in the high-dose group at day 6 and 7 of the application of the drug. Therefore a fourfold overdosing of ronidazol should be avoided. 相似文献

Retrospective study of prophylactic random transscleral retinopexy in the Bichon Frise with cataract
The objective of this study was to determine the efficacy of prophylactic random transscleral retinopexy (PRTR) in preventing rhegmatogenous retinal detachment (RRD) in the Bichon Frise with juvenile cataract. The medical records were reviewed from a private veterinary ophthalmology practice of nondiabetic Bichon Frise dogs younger than 11 years that had inherited cortical cataracts in one or both eyes and that had a follow-up examination after at least 9 months. Eyes were included in the study if the fundus could be visualized by indirect ophthalmoscopy at the last examination either because of phacoemulsification or resorption of the cataract. Four groups of eyes were identified. In group 1, no PRTR was performed and there was resorption of the cataract; in group 2, eyes had no PRTR performed and phacoemulsification of the cataract. Group 3 had PRTR performed and resorption of the cataract. In group 4, PRTR was performed as was phacoemulsification of the cataract. In group 1, 20 eyes had resorbed cataracts, and 12 (60%) of these had RRD. In group 2, 18 eyes had phacoemusification of the cataract, and 10 (55%) of these had RRD. In group 3, 19 eyes had PRTR and resorbed cataracts, and 2 (10%) of them had RRD. In group 4, 39 eyes had PRTR and phacoemulsification of the cataract; of these 5 (12%) had RRD. The Bichon Frise dog with inherited cataract is at high risk of RRD. PRTR reduces this risk. 相似文献

A cross-sectional study was undertaken to determine the presence and prevalence of salmonellae in retail raw chicken meat and giblets (gizzard and liver) in supermarkets in Addis Ababa (Ethiopia). A total of 301 samples (244 chicken meat, 32 gizzards and 25 livers) were collected from 22 randomly selected supermarkets and examined for the presence of Salmonella. For the isolation and identification of salmonellae, the technique recommended by the International Organization for Standardization (ISO 6579, 1998) was used. Salmonellae were detected from 54 (17.9%) of the 301 samples examined. Chicken meat and giblet samples in 68.2% (15/22) of the supermarkets were contaminated with salmonellae. The contamination level of Salmonella was higher in chicken giblets as compared to chicken meat, which were respectively 12.3%, 53.1% and 28.0% in chicken meat, gizzard and liver samples. Out of the 54 Salmonella isolates, nine different serotypes were identified: Salmonella Braenderup (31.5%), S. Anatum (25.9%), S. Saintpaul (14.8%), S. Uganda (11.1%), S. Haifa, S. Group B, S. Rough form and S. Typhimurium (each 3.7%) and S. Virchow (1.8%). The high level of Salmonella contamination of chicken meat and giblets observed in the present study indicated the need in an improvement in the microbiological quality of retail chicken in Ethiopia. 相似文献

In a field study 63 commercial cattle transports to German slaughter plants including 580 bulls, cows and heifers were investigated to estimate the impact of pre and post transport aspects on animal welfare. Study 1 evaluated these aspects as part of a large model covering all possible influences at transport and slaughter on biochemical stress response and carcass and meat quality. Included were keeping system, behavioural and clinical observations at loading, unloading and lairage, transport time, loading density, mounting prevention, regrouping and lairage time. In study 2 more detailed questions about loading and unloading were answered by investigating the impact of facility design and handling criteria on cattle behaviour and heart rate. Cattle from tied housing show an increased stress response to all transport procedures. Many aspects of facility design and handling contribute to quality of loading. Cattle show calmer behaviour, turn, balk or fall less if they are not mixed and driven in small groups on driveways without impediments but with regular sideblock, not wider than the vehicle ramp. Vehicle ramps should have high and closed side gates, be inclined less than 20 degrees, and the step towards ramp should be less than 15 cm. Unloading is improved if performed level and to the back of the vehicle (behaviour, heart rate, cortisol, CK). Direct reloading should be avoided and mounting should be prevented during transport and lairage (CK, lactate, bruising). But mounting prevention devices may increase bruising if set too low (< 20 cm above withers). Longer lairage time is disadvantageous (CK, energy metabolism). 相似文献
