Susceptibilidade a antimicrobianos de bactérias isoladas de otite externa em cães / Antimicrobial sensitivity of bacteria from otitis externa in dogs

The occurrence of canine externa otitis in Fortaleza-Ceará is reported. About 91.5 percent of the animals with clinical signs were positive to bacterial culture. Among all infections, 49.5 percent were mixed infections and the most common pathogens were Staphylococcus spp coagulase negative or positive and Pseudomonas aeruginosa.

Perfil hematológico e avaliação eletroforética das proteínas séricas de cães com cinomose / Hematological profile and electrophoretic evaluation of serum proteins of dogs with canine distemper

The hematological and serum proteins electrophoretic profiles of 13 dogs with distemper (Lentz inclusion body in leukocytes) were studied. The most frequent hematological findings were: normocitic normocromic anemia (61%), leukopenia (46%), left shount (54%), trombocytopenia (69%) and lymphopenia (85%). Electrophoretic analysis of serum proteins showed hypoproteinemia (54%), with reduced albumin and increased alfa-2 globulin. These findings can be used to support the clinical diagnosis of canine distemper.
