Abstract: 

The purpose of this study was to determine the prevalence of K99 positive E. coli isolates in diarrheic and non-diarrheic calves. A total of 114 and 68 swab samples were obtained from diarrheic and non-diarrheic calves (fewer than 3 weeks age) respectively. The samples were cultured for E. coli isolation. E. coli Isolates were subjected to 3 consecutive passages for 24 hours on Minca agar at 37oC. All E. coli isolates were examined by direct immunofluorescence and hemagglutination tests. According to biochemical tests 96 isolates from diarrheic calves and 63 from non-diarrheic cases were confirmed. On direct immunofluorescence test 45.83% (44) and 17.46% (11) of isolates respectively from diarrheic and non-diarrheic cases were positive for K99 antigen. On hemagglutination test, 21 (21.87%) E. coli isolates from diarrheic calves and 7 (11.11%) isolates from non-diarrheic cases showed positive reaction.
