Electrophoretic changes in Escherichia coli and Clostridium perfringens recovered from enteritis in quails after exposure to enrofloxacin.
Abstract: E. coli and C. perfringens were isolated from the intestinal contents of quails suffering from enteritis at different incidences either alone or concurrently mixed together. C. perfringens types A and D were identified and type D was the most predominant. E. coli isolates were sensitive to enrofloxacin, ceflifur, chloramphenicol, flumequine and spectinomycin. Meanwhile, C. perfringens isolates were sensitive to ampicillin, penicillin-G, lincomycin, enrofloxacin and flumequine. MIC of enrofloxacin to E. coli was 80 µg/ml and its MBC to C. perfringens type D was 2.5 µg/ml. Electrophoretic analysis of E. coli and C. perfringens type D strains post-exposure to small doses of enrofloxacin showed marked differences in the number of the obtained bands, molecular weight of each band and amount of the band in comparison to the obtained results before their exposure to enrofloxacin. These results explain the appearance of mutants post- exposure to mild doses of antibiotics. These mutants differ in structure than their parents and have marked affinity for antibiotic resistance.
