[The occurrence of O-antigens of Escheria coli strains in calves suffering from diarrhea in the Eastern Bohemian Region].
Coli infections in calves belong to the most serious diseases occurring in the early post-natal period and causing considerable losses to large cattle stocks. The calves affected by diarrhoea were studied as to the serological typification of E. coli. The total number of the calves examined was 1182. The examination yielded 2112 isolated strains. Twelve antisera made it possible to identify 569 strains, i. e. 26.94 %. O-antigens were found to occur with the following descending frequency: 015, 0139, 0117, 0141, 08, 0149, 09, 0101, 02, 0147, 078, and 0115. Although it is obvious that enteropathogenic strains of E. coli were not responsible for all cases of diarrhoea in the examined calves, the total set of animals was large enough to show which O-antigens could be involved in the diarrhoea in the calves kept on large cattle farms in the East Bohemian region.
