Abstract
240 samples of urine male and dogs ranging from 1 to 14 years old were inspected and cultivated in media such as blood agar and Levine. 133 samples (55,4%) showed to be positive and the most isolated microrganisms were: Escherichia coli (40,1%), Streptocus canis (17,7%), Proteus mirabalis (14,6%) and Staphylococcus aureus (11,5%). Escherichia coli showed to be more sensible to gentamicin and chloranfenicol; ampiciline acted on wel against Streptococcus canis, while Proteus' samples had more sensibility to gentamicine and ampiciline; both chloranfenicol and gentamicine were efficient against Staphylococcus aureus.
