Susceptibilidade antimicrobiana de amostras de Escherichia coli isoladas de frango industrial (Gallus gallus domesticus - Linnaeus, 1758) com colibacilose / Antimicrobial susceptibility of samples of Escherichia coli isolated from industrial chickens (Gallus gallus domesticus - Linnaeus, 1758) with colibacillosis

RESUMO

O presente estudo avaliou a susceptibilidade de amostras de Escherichia coli isoladas de quadros de colissepticemia aviária da região centro-oeste paulista pelo Laboratório de Ornitopatologia da FMVZ-UNESP/Botucatu, SP. Constatou-se um grande número de amostras multirresistentes aos antibióticos testados, onde as drogas menos efetivas foram sulfonamida e tetraciclina. Todas as amostras mostraram-se sensíveis a norfloxacina e gentamicina.

ABSTRACT

The present study evaluated the susceptibility of Escherichia coli samples isolated from poultry with colisepticemia in midwestern São Paulo State at the Ornitopathology Laboratory of FMVZ-UNESP/Botucatu, SP. A large number of samples were found that were multi-resistant to the antibiotics tested, the less effective drugs being sulfonamide and tetracycline. All samples were susceptible to norfloxacin and gentamicin.
