Perfil de sensibilidade in vitro de Escherichia coli isolados de alimentos de origem animal

Abstract

Several studies indicate microbial infection at minas fresh cheese, pork and chicken meat, this factor damage the quality and integrity of these products. One of these pathogens that frequently found was Escherichia coli bacterium, microorganism directly related at food improper handling and lack hygiene during the processing. The objective of this work was verifying the sensibility in vitro E. coli isolated from minas fresh cheese, pork and chicken meat. The microbial sensibility was done by Nacional Committee for Clinical Laboratory Standards (NCCLS). The antimicrobials used to sensibility verify were ampicillin, tetracycline, chloramphenicol, amoxicillin, ciprofloxacin, gentamicin, norfloxacin, streptomycin, vancomycin, erythromycin, amicanina, nalidixic, imipenem, teiclopanina, imipene and penicillin on sixty-one E. coli isolated. The results shown E. coli strains multiresistant from chiken meat and pork. The strains from fresh cheese shown high sensibility by antimicrobial tested. Every isolated were resistant to erythromycin and tetracycline antimicrobials.
