Antibiotic sensitivity profile of the test isolates of E. coli isolated from clinical cases of diarrhea in the kids of goat breeds

Abstract

The samples were taken using sterile cotton swab tubes, and were labeled and kept in the refrigerator at 4°C until further processing. These samples were collected from less than one month old Jamunapari, Barbari, Jakharana, Sirohi kids during the period from March to June 2010. Some of the commonly used antibiotics like Ampicillin, and Cloxacillin were giving high percentage of resistance at the rate of 75 percent and 100% respectively. This is due to the unscrupulous use of such antibiotics leading to high resistance. About 67 percent of the isolates were resistant to Oxytetracycline, Gentamicin, and Ceftriaxone. Only antibiotic groups like fluoroquinolones and the Chloramphenicol have fared well in effectively inhibiting the in vitro growth of E. coli. Chloramphenicol has given the lowest percentage of resistance at zero and the next best was Enrofloxacin at 34 percent. So, it’s a serious issue that out of the commonly used 7 antibiotics, only two was effective, which gives clue about the emerging multi-drug resistant E. coli strains.
