RESUMO

Este trabalho objetivou determinar os microrganismos bacterianos no saco conjuntival de cães clinicamente normais e cães com ceratoconjuntivite seca (CCS), atendidos no Hospital de Medicina Veterinária da Universidade Federal da Bahia. Foram incluídos na pesquisa 30 animais sadios e 28 com CCS. Foi observado crescimento bacteriano em 60% das amostras oculares dos cães sadios e em 89,29% dos cães com CCS. Houve predomínio de espécies Gram positivas em ambos os grupos. Nos animais normais as bactérias mais prevalentes foram Staphylococcus intermedius (26,83%), seguido por Staphylococcus aureus (21,95%) e Staphylococcus epidermidis (19,51%). Houve identificação de leveduras em 38,34% das amostras. Dos 30 animais sadios estudados, 46,66% apresentaram cultura positiva bilateral, 26,67% cultura positiva unilateral e 26,67% cultura negativa. Nos animais com CCS, as bactérias de maior prevalência foram o Streptococcus β-hemolítico (16,13%), seguido por Staphylococcus intermedius (12,90%) e o Staphylococcus aureus (11,83%). Ocorreu identificação de leveduras em 19,64% das amostras. Dos 28 animais com CCS, observou-se que 82,14% apresentaram cultura positiva bilateral e 17,86% cultura positiva unilateral.This study aimed to determine the bacterial microorganisms in the conjunctival sac of clinically normal dogs and of dogs with keratoconjunctivitis sicca (KCS) attended at the Veterinary Hospital of the Federal University of Bahia. Thirty health animals and 28 with KCS were included in the research. Bacterial growth was observed in 60% of the healthy dogs and in 89.29% of the dogs with KCS. There was a predominance of Gram-positive species in both groups. In normal animals, Staphylococcus intermedius (26.83%), followed by Staphylococcus aureus (21.95%) and Staphylococcus epidermidis (19.51%) were the most prevalent bacteria and the identification of yeasts in the samples of this group was 38.34%. Of the 30 healthy animals studied, 46.66% showed bilateral positive culture, 26.67% had unilateral positive culture and 26.67% had negative culture. In animals with KCS, Streptococcus β-hemolytic (16.13%), followed by Staphylococcus intermedius (12.90%) and Staphylococcus aureus (11.83%) were the most prevalent bacteria. Yeast identification in this group occurred in 19.64% of the samples. Of the 28 animals with KCS, 82.14% showed bilateral positive culture and 17.86% unilateral positive culture.
