SURVEY OF PSEUDOMONAS-AERUGINOSA CONTAMINATION IN HUMAN-BEINGS AND LABORATORY-ANIMALS

Several serotypes of Pseudomonas (P.) aeruginosa were isolated from th e oral cavities of researchers, but no positive cases were found among the animals they had contacted or in the environment. These results i ndicated that researchers are not a source of P. aeruginosa infection for animals. However, P. aeruginosa was detected on the hands of resea rchers 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 care takers were contaminated with P. aeruginosa by the animals, and then b ecame infective vehicles.
