Abstract
The authors studied the indication and antibiotic sensitivity of E. coli O157:H7 isolates isolated from soil, meat samples and objects subjected to veterinary surveillance. In a study on isolation of Enterohaemorrhagic E. coli from various environmental media 6602 samples were examined. The highest number of E. coli O157:H7 was isolated from soil in 10 % and meat in 8.7 % of cases. E. coli O157:H7 was isolated in 2.6% of cases from wipes of objects subjected to veterinary surveillance. This microorganism was not detected in feed of plant origin. Antibacterial sensitivity studies of isolated E. coli O157:H7 isolates revealed 100% sensitivity to cefotaxime, cefepime, imipenem, ciprofloxacin, ceftriaxone. The authors observed an 80-90% sensitivity of isolated strains to norfloxacin, cefoxitin, gentamicin and ceftazidime. Studies also showed complete resistance of E. coli O157:H7 isolates to tetracycline in 80% of microorganisms. Of these, 2 cultures were isolated from soil and 6 cultures from meat from forced slaughter.
