説明

Some investigations were carried out on airborne bacteria in different parts of laboratories. The results are summarized as follows:<BR>1) The numbers of air-borne bacteria were much different among animal rooms under different conditions. (Fig. 2) .<BR>2) Bacterial number in the experimental room attained its maximum at daytime and its minimum at night (Fig. 5) . The mean number of air-borne bacteria in animal room however, was larger at night than at daytimes (Fig. 4) . The daily changes of bacterial number in the vestibule were similar to those in the experimental room (Fig.3) .<BR>3) The numbers of bacteria in animal rooms before and after introduction of animals was considerably different. (Fig.6 & 7) .<BR>4) The numbers of air-borne bacteria in the animal rooms differs with the species of animals. The highest contamination was observed in the rabbit room.<BR>5) The difference in number of bacteria between the levels of 170 cm and 20 cm distant from the floor was obserbed (Fig. 6 & 7) .<BR>6) Over 90 per cent of the contaminated bacteria were of underf fined micrococci, and the rests were of diphtheroids, coliforms and fungi (Table. 2) .
