Based on examination of the plasmid profile it may be assumed that very probably a nosocomial spread of the strains was involved. This is suggested by the identical plasmid profile of all strains isolated in the environment and five strains isolated from neonates. On investigation of the enterotoxicity of culture filtrates of the investigated strains the authors did not reveal the presence of a thermolabile or thermostable enterotoxin. In the skin test on rabbits 93.8% of the tested samples were positive. Morphological changes on Vero cells after 48 hours action were produced by four culture filtrates. Only two strains caused haemolysis of agar with 6% sheep and rabbit blood after incubation at 37 degrees C. Another 14 strains caused lightening of the agar with rabbit blood after subsequent incubation at 4 degrees C.</p>","PeriodicalId":75687,"journal":{"name":"Ceskoslovenska epidemiologie, mikrobiologie, imunologie","volume":"41 3","pages":"157-65"},"PeriodicalIF":0.0,"publicationDate":"1992-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"12560460","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The most important of thus transmitted diseases is rabies. Cats become infected from foxes on rubbish heaps on the periphery of communities. More than 60% of cases of rabies of domestic animals are found in cats. Toxoplasmosis--cats excrete the infectious stage of the causal agent in their excreta. In the same manner also the agent causing intestinal salmonelloses is excreted. More than 5% cats are infected. Via excreta also the causal agents of toxocariasis are spread--the larvae of cat thread worms settle in the internal organs of humans (larva migrans). The assumed incidence in cats is as high as 50%, as suggested also by the high positivity of specimens from children playgrounds. Stray cats may be the source of agents causing various dermatomycoses and of ectoparasites.</p>","PeriodicalId":75687,"journal":{"name":"Ceskoslovenska epidemiologie, mikrobiologie, imunologie","volume":"41 3","pages":"169-73"},"PeriodicalIF":0.0,"publicationDate":"1992-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"12559109","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the majority the materials were not from the same individual. Lungs were examined by the ELISA method, antibodies were assessed by the indirect immunofluorescence reaction. An antigen resembling the western subtype (Puumala) was found in 65 animals (5.9%) of two rodent species (Microtus arvalis--63 times and Apodemus flavicollis--twice) in 20 localities. Antibodies against this subtype were detected in 25 examined individuals (4.0%) of four species (Microtus arvalis, Apodemus flavicollis, Pitymys subterraneus and Lepus europaeus) from eight localities. A marked predominance of positive findings was obtained from Microtus arvalis which under conditions of the South Moravian region can be considered the main host of hantaviruses of the western subtype. Only in one specimen of Clethrionomys glareolus from Hrbov antibodies against the eastern subtype were detected (Hantaan). Hantaviruses form in Southern Moravia natural foci of the avector type, in particular in perennial fodder crops, most frequently with a mesophil character of the site.
