Outline of Final Research Achievements

We aimed to establish the method to reconstruct oral flora from deposited food remnants with attached saliva in wild chimpanzees. By comparison of oral flora composition between primate species, we tested the hypothesis that food sharing would facilitate the transmission of oral microbiotic species including major pathogenetic bacteria such as porphyromonas gingivalis. We collected over two hundred samples in the Kalinzu Forest, Uganda in 2016 and 2017. The sampled primate species ranged from chimpanzees, blue monkey, red-tailed monkey, l’Hoest’s monkey, and abyssinian black-and-white colobus We analyzed over 80 samples and succeeded in the extraction and amplification of universal DNA sequence segment (V1-V2) in 16SrRNA coding region. This is the first data of oral bacterial flora from wild animals in Kalinzu. We will present the results of this study in the 34th annual meeting of Primate Society of Japan and will publish them in international journals
