Time Related Fungal Contamination of Animal Cage Beddings
The purpose of the study was to measure the extent of fungal contamination in laboratory animal cage beddings over time. The material was analysed for the content of fungal enzyme N-acetylhexosaminidase and the fungal cell wall agent 1,3-ß-glucan at 0-7 days after use. In some cages the values were increased above baseline already at 3 days and at 7 days practically all beddings showed a fungal contamination. It is suggested that the fungal enzyme test can be used for bedding quality control purposes and to monitor fungal contamination in animal cages to prevent pulmonary and other pathologies.
