Antimicrobial susceptibility tests were determined in 100 isolates of E.coli from differents patologies in cattle, horses, dogs and cats, according to Clinical and Laboratory Standards Institute. Multiresistance isolates were detected in this assay. The antibiotics selected were amikacin, ampicillin /sulbactam, cefotaxime, ciprofloxacin, chloramphenicol, colistin, gentamicin, nitrofurantoin, streptomycin, tetracycline, trimethoprim/sulfamethoxazole. The antibiotic with the highest resistance was tetracycline (34% in cats and 75% in dogs). In isolated strains from dogs and cats it was also found considerable percentages of resistance to ampicilline/ sulbactam (27% in dogs and 53%in cats) and to ciprofloxacine (30%in dogs and 67% in cats). In these isolates it was also found the highest percentage of multiresistance (29% in dogs and 67% in cats). Selective pressure originated from the inadecuate use of antibiotics can be responsible for the appearance of resistance, eventhough it is not the only one. It may be possible that E. coli could transmit genes of resistance to antimicrobials agents, although it is unknown if the presence of these genes are permanent or transitory. Fil: Carloni, G.

Gentilini, E. 2011 Se determinó el perfil de susceptibilidad a antimicrobianos de 100 aislamientos de E.coli provenientes de diversas patologías en bovinos, equinos, caninos y felinos, siguiendo metodología del Clinical and Laboratory Standards Institute y detectando la aparición de aislamientos multiresistentes. El panel de antibióticos ensayados incluyó amicacina, ampicilina/sulbactama, cefotaxima, ciprofloxacina, cloranfenicol, colistina, estreptomicina, gentamicina, nitrofurantoína, tetraciclina, trimetoprima/sulfametoxazol. El mayor porcentaje de resistencia (R) se detectó frente a tetraciclina en aislamientos de todas las especies animales (entre 34% en los de origen felino y 75% de origen equino). En las cepas de origen canino y felino se encontraron porcentajes considerables frente ampicilina/ sulbactama (27% de caninos y 53% de felinos) y ante ciprofloxacina (30% y 67% respectivamente). En estos aislamientos también, se detectó el mayor porcentaje de multiresistencia (29% en caninos y 67% en felinos). La presión selectiva originada por la aplicación inadecuada de antibióticos puede resultar un factor, aunque no el único, responsable de la aparición de R. Además existe la posibilidad de que E.coli pueda constituirse en un eslabón de transmisión de genes de R a antimicrobianos, aunque no se conoce hasta el momento, el origen de ellos, humano o animal y, su permanencia en el tiempo. application/pdf 1514-6634 (impreso) 1668-3498 (en línea) antimicrobianos resistencia E.coli antimicrobials resistance E.coli spa Universidad de Buenos Aires.
