Several serotypes of Pseudomonas (P.) aeruginosa were isolated from the oral cavities of researchers, but no positive cases were found among the animals they had contacted or in the environment. These results indicated that researchers are not a source of P. aeruginosa infection for animals. However, P. aeruginosa was detected on the hands of researchers and animal caretakers after they finished their work. The same serotype of P. aeruginosa was found in the animals and the environment. These findings demonstrated that the researchers and the animal caretakers were contaminated with P. aeruginosa by the animals, and then became infective vehicles.
