Figures and Facts on Animal Research at the University of Basel
The University of Basel maintains detailed records of the total number of experiments conducted on vertebrate animals and the distribution of degrees of severity. These statistics are reported to the Federal Food Safety and Veterinary Office, which compiles national data.
Mice make up by far the largest proportion of animals, accounting for around 95%.

Approximately one-third of the experiments result in no stress for the animals, while another third each, is classified as having mild or moderate stress, respectively. The remaining five percent of experiments involve severe stress. More information on the definition of severity levels, as well as examples of experiments with different degrees of severity, is provided on the Values and Responsibility page.

A dedicated team of veterinarians and trained animal caretakers holds the responsibility of caring for and monitoring the animals at the University of Basel. Their efforts enable life science research groups to conduct advanced research and supplement their studies with animal experiments.
