Parasitological research of wild primates living in Kalinzu Forest

Report: Ejima Shun

Date: 2012/1/4 - 2012/2/29

From 7th January to 26th February 2012, I stayed at the Kalinzu Forest Reserve, Republic of Uganda and investigated the gastrointestinal helminths of wild primates living there. The study subjects were 6 species (red-tailed monkey, blue monkey, L'hoest's monkey, chimpanzee, black-and-white colobus and anubis baboon). First I followed target primate species with a tracker and when the defecation was seen, I collected their feces immediately. During the day, I weighed the fecal samples and calculated the number of parasite eggs by a simple fecal sedimentation method and sucrose floatation method under the microscope. The surplus fecal samples were put in 50ml polystyrene tubes with 70% ethanol and a total of 165 tubes were brought back to Japan for further analysis. Some fecal samples were used for larva culture by nutrient-agar-medium method and brought back to Japan. The larvae were used for further identification and materials of DNA analysis. Soon after returning to Japan, I reported about the distribution of 3 universally seen parasite genus from my preliminary data in the seminar of Social Behavior and Ecology Section. Hereafter I am planning to conduct further parasite identification and calculation of parasite eggs, and phylogenetic analysis using extracted DNA from eggs and larvae, to complete my master's thesis.
