Microbiological monitoring

JCRB Laboratory Animal Resource Bank is periodically monitoring microbiological status of our animal colonies in all rooms (four times a year).

In rooms for general research uses, sentinel animals are placed in each room and used for the monitoring.

In rooms for maintaining breeding cores of strains, some animals, mainly retired ones, per strain are selected for microbiological monitoring.

Microbiological examinations are being conducted by an outsourced organization, ICLAS Monitoring Center, Central Institute of Laboratory Animals.
