SUMMARYIsolation and enumeration for causative organisms of zoonosis were investigated in the oral cavities of 65 dogs. Of them, 50 were kept as pet dogs and 15 were captured and brought to the administration center for animals. Streptococcus(92.0%), Staphylococcus(86.0%), coliform groups(78.0%), Candida(26.0%), Clostridium perfringens(12.0%) and Pasteurella multocida(8.0%) were found in the oral cavities of pet dogs. On the other hand, coliform groups(100%), Staphylococcus(100%), Streptococcus(100%), C. perfringens(100%), Candida (40.0%), P. multocida(33.3%) and Yersinia(13.3%) were detected from those of captured dogs. It was indicated that the mean number of coliform groups, C. perfringens, Staphylococcus, Streptococcus and P. multocida in captured dogs was higher than that of the pet dogs.
