The working group 'Pathology of non-human primates' works on different aspects of non-human primate diseases. Besides animal models , e. g. pox virus infections in marmosets, spontaneous infectious diseases such as echinococcosis, tuberculosis or tularemia are part of the investigations. But also non-infectious disease entities as the marmost wasting syndrome of marmosets and endometriosis of rhesus macaques are included in our research.
