This work is a contribution to the study of faun-human interactions in the surroundings of the Kahuzi-Biega National Park. The subject matter of our study focuses on human reports on the fauna, in the situation where will animals predators being plants, present some risks of human contamination. In fact, our investigation has shown that certain plants preferred by KBNP primates constitute a common point between the PBNK faun and Bugorhe population. The microscope analyses done in the laboratory show that the KBNP done in the laboratory show that the KBNP Baboons, pets and Bugorhe citizens have parasites, sometimes common to different groups. This presets the risks of zoo noses and other occasional diseases for both the PNKB faun and the Bugorhe population.
