Animals that are free from pathogens are not only required for reasons of animal welfare. These microbiologically standardized animals are also an absolute necessity. They are also a prerequisite for meaningful and reproducible test results. These help to reduce the number of animals necessary in order to a minimize the animals required in accordance with the 3R concept. The tasks of microbiological diagnostics are to characterize and ensure the hygienic status of the test animals. To ensure the proper cleaning, disinfection or sterilization of rooms and equipment (environmental control). Also to organize and monitor the control measures for a pest free environment.
At the University of Hohenheim, the ZVH 670 is subject to central hygienic supervision, as well as decentralized facilities where small laboratory rodents are kept.
