THE AIR MICROFLORA OF SELECTED ANIMAL ENCLOSURES IN THE ZOO


Zoos are a kind of conglomerate of artificial environments created for both native and exotic animals. It is expected that the microflora in the enclosures for different animals will be highly diverse due to the surface and volume of the rooms, the origin of the animals and their environmental requirements. The study was conducted from May to October 2016. 9 groups of animals were examined. Inside the enclosures were investigated: microflora (using a 6-step Andersen-Graseby impactor), dustiness (using the DustTrak II dust meter) and microclimatic conditions. The concentration of the total number of bacteria, staphylococci, molds and fecal bacteria in the air of the enclosures were examined. The highest concentrations of all tested microbial groups were found in tapir rooms, while the lowest in the ostrich room.
