Staphylococcus hyicus, the cause of exudative epidermitis of swine. Review     

C L?mmler 《Berliner und Münchener tier?rztliche Wochenschrift》1990,103(2):60-63

Staphylococcus hyicus, the cause of porcine exudative epidermitis, could be clearly differentiated from S. aureus, S. epidermidis and from other staphylococcal species. This was based on cultural, biochemical and serological properties. A positive coagulase reaction in porcine plasma, the detection of protein A like IgG Fc-receptors and the specific reaction of the cell wall teichoic acid allowed further characterization of this species. S. hyicus additionally produced enzymes with bacteriolytic properties.  相似文献   

Seroepidemiologic studies of the agent of respiratory diseases in cattle     

A Pernthaner  W Baumgartner  S Cerny-Reiterer  J K?fer 《DTW. Deutsche tier?rztliche Wochenschrift》1990,97(6):254-257

In a period of three years epidemiological studies were carried out in Styria concerning the occurrence of antibodies against BRSV (Bovine Respiratory Syncytial Virus), Adeno I Species 3-Virus, Adeno II Species 8-Virus, PI-III (Parainfluenza 3-Virus), IBR/IPV-Virus and Chlamydia. A total of 1376 serum samples were examined and showed different titers of specific antibodies against respiratory pathogens. 449 blood samples were submitted to serological examinations in the year 1984, 525 in 1985 and 402 in 1986. Antibodies against BRSV could be found in 17.4% of the sera or in 55.9% of the herds. Specific antibodies against Adeno I Species 3 occurred in 33.9% of the sera resp. in 74.2% of the units. 35.2% of the cows or 80.1% of the herds showed positive SN-titres against Adeno II Species 8. IBR/IPV-specific antibodies were detected in 2.3% of the sera resp. 3.8% of the herds. Antibodies against Chlamydia could be found in 8.8% of the cows or in 22.6% of the units. In the years mentioned above significant differences of antibodies against BRSV, Adeno I Species 3, Adeno II Species 8 and Chlamydia could be observed, but not against PI-III and IBR/IPV as well. By means of the Chi-Square-Test significant differences between Simmentaler, Austrian Brown Cattle and Holstein Friesian regarding antibodies against IBR/IPV and Adeno II Species 8 could be found. No significant differences between the serological results of herds, which contained on of the three breeds could be observed.  相似文献   

Thermophilic Campylobacter from fecal samples of animals and their behavior in the ganglioside (GM1)-ELISA, Vero cell test and salt aggregation test     

R Rakotozandrindraini  H P Hamann  M Zsch?ck  T Schliesser 《Zentralblatt für Veterin?rmedizin. Reihe B. Journal of veterinary medicine. Series B》1990,37(2):142-147

From 397 fecal specimens from apparently healthy and from diarrheic pigs, dogs, cats and cattle 59 strains (= 15%) of thermophilic Campylobacter (C.) spp. were isolated by culture. 39 strains were identified as C. coli and 18 as C. jejuni whereas 2 isolates could not be classified. None of the strains was found to be positive for cytotoxic enterotoxin in the GM1-ELISA. In the Vero-cell test 5 isolates showed a cytotoxic effect. The salt aggregation test (SAT) for indicating cell surface hydrophobicity was positive with 24 strains (5 C. jejuni, 19 C. coli). A correlation of isolation results with clinical manifestation could not be observed.  相似文献   

The pathomorphology and pathogenesis of acute cardiovascular failure in swine. 3. Histopathologic findings in the myocardium of swine with transport-related cardiovascular insufficiency     

V Bergmann  A Gr?fe  H Seifert 《Archiv fuer experimentelle veterinaermedizin》1990,44(4):521-532

Quantitative pathohistological investigations were performed on 300 samples of five different myocardial regions from 50 pigs with had suffered stress-related myocardial insufficiency on their transport to the slaughterhouse (transport exhaustion). The findings were compared to 1,200 myocardial samples from 200 clinically intact pigs for slaughter. Animals with transport-related damage exhibited with significance more and more severe inflammatory and degenerative myocardial alterations, such as round-cell infiltration, fiber necrosis, calcification, and fat infiltration. Many of these lesions had been manifest already prior to transport. Myocardially predamaged pigs were less capable than others of sustaining transport stress and were more predisposed to cardiac failure. Stress-related cardiovascular insufficiency, consequently, depended not only on direct stress but also on the general health condition of the myocardium. Causes and pathogenetic relevance of these alterations are discussed in some detail.  相似文献   

Effect of iodine, copper and zinc additions to the diet with a high proportion of coarse rape meal extract on the growth and thyroid function of fattening pigs. 1. The effect on fattening performance     

H Lüdke  F Sch?ne  A Hennig 《Archives of Animal Nutrition》1985,35(12):835-845

In three experiments with fattening pigs the supplementation of a ration with 8% rapeseed oilmeal (RSO) with 1 mg J/kg resulted in an increased weight gain per day of 31, 94 and 87%. On the other hand, only 83, 76 and 84% of the weight gain of the soybean oilmeal control groups were achieved. The additional supply with 250 mg Cu (experiments II and III) increased the weight gain to 84 and 96% in comparison to the unsupplemented control groups. The combination of J + Cu + Zn lead to the same performance as that of J + Cu (experiment III). In the RSO groups without J-supplement changes in body proportions and parakeratosis could be observed after approximately equal to 7 weeks. After the sole supplementation of Cu these symptoms occurred approximately equal to 4 weeks later. In vitro, the supplementation of RSO with a CuSO4 solution resulted in a decrease of vinylthiooxazolidon and isothiocyanate in line with the CuSO4-concentration. 0.2 mg J/kg feed (experiment III) resulted in the same fattening performance as the supplementation of the ration with 1 mg J and outwardly visible deficiency symptoms. The results show that Cu, depending on its quota, results in a decrease of goitrogenics in the feed and that J and Cu supplementation to rations with rapeseed oilmeal have an additive effect and that parakeratosis can be prevented by J-supplementation.  相似文献   

Diagnosis of pancreatitis.     

J?rg M Steiner 《Veterinary Clinics of North America: Small Animal Practice》2003,33(5):1181-1195

In summary, pancreatitis is common in dogs and cats, but it seems that most cases remain undiagnosed. Serum amylase and lipase activities are useful as a quick screening test for pancreatitis in the dog only. Serum amylase or lipase activity must be at least three to five times the upper limit of the reference range to suggest a diagnosis of pancreatitis. Furthermore, the diagnosis must be confirmed by other diagnostic modalities, and normal test results do not eliminate the possibility of pancreatitis. Abdominal ultrasound is highly specific for pancreatitis in dogs and cats but is not particularly sensitive, especially in cats. Serum cPLI concentration is highly specific for exocrine pancreatic function and is also highly sensitive for pancreatitis. Similarly, initial data would suggest that serum fPLI is the most sensitive and specific diagnostic test for feline pancreatitis. Until further data are available, however, serum fPLI should be used in conjunction with other diagnostic tests to arrive at a diagnosis of feline pancreatitis. Histopathologic evidence of pancreatitis is conclusive for a diagnosis of pancreatitis. In most cases, however, lesions are localized, and the lack of histopathologic evidence of pancreatitis does not eliminate a diagnosis of pancreatitis.  相似文献   

Tuberculosis survey of free-ranging marsh deer (Blastocerus dichotomus) in Brazil.     

Janaina O Luna  Manoel A A Santos  Edison L Durigon  Jo?o P Araújo Júnior  José M B Duarte 《Journal of zoo and wildlife medicine》2003,34(4):414-415

Esophageal-pharyngeal fluids from 53 free-ranging marsh deer (Blastocerus dichotomus) captured for a research program in the state of Mato Grosso do Sul, Brazil, were assayed for tuberculosis. Total DNA was extracted. amplified by polymerase chain reaction using specific primers for Mycobacterium tuberculosis complex (M. tuberculosis, M. bovis, M. microti, and M. africanum), and observed by agarose gel electrophoresis stained with ethidium bromide. All samples were negative. This, along with necropsy and histopathology data, suggests that these animals are not shedding and probably do not have active disease.  相似文献
