Sensibilidad antimicrobiana de aislamientos bacterianos de casos clínicos de origen porcino y aviar

The antimicrobial resistance sensibility profiles against fosfomycin, difloxacin, gentamicin, amoxicillin-clavulanic acid, enrofloxacin and tetracycline of five bacterial genera of porcine and avian source isolated from clinical cases were studied. The diffusion agar was the methodology used. A high percentage of sensible strains to gentamicin was found, with the exception of Streptoccus generum that had a high percentage of intermediate sensibility strains. All the isolates were sensible to amoxicillin-clavulanic acid, excepting one Salmonella Infantis strain from avian source that was resistant. A high percentage of resistant isolates to tetracycline was found. The results obtained for the two quinolones tested (enrofloxacin and difloxacin) were similar, a high percentage of sensible strains was obtained with the exception of some Escherichia coli isolates from porcine and avian source and some Staphylococcus aureus strains from avian source that showed a high percentage of resistance. All the isolates were sensible to fosfomycin. It is very important to know the situation and the evolution of the bacterial resistance to different antimicrobials used in veterinary medicine.
