Balantidiasis is considered a neglected zoonotic disease with pigs serving as reservoir hosts. However, Balantidium coli has been recorded in many other mammalian species, including primates. Here, we evaluated the genetic diversity of B. coli in non-human primates using two gene markers (SSrDNA and ITS1-5.8SDNA-ITS2). We analyzed 49 isolates of ciliates… (More)
BACKGROUND Infectious diseases represent the greatest threats to endangered species, and transmission from humans to wildlife under increased anthropogenic pressure has been always stated as a major risk of habituation. AIMS To evaluate the impact of close contact with humans on the occurrence of potentially zoonotic protists in great apes, one hundred… (More)
Comparison of diagnostic methods for Plasmodium spp. in humans from Uganda and the Central African Republic showed that parasites can be efficiently detected by PCR in fecal samples. These results, which rely solely on PCR-based examination of feces, validate numerous estimates of the prevalence of malaria in great apes.
Understanding variability in patterns of parasite infections requires studies of multiple populations inhabiting a variety of habitats. Gastrointestinal parasites of chimpanzees (Pan troglodytes) have been studied extensively at several forested sites, but the parasite fauna of chimpanzees living in dry, open habitats is less well known. We studied the… (More)
Infections caused by the intestinal ciliate Neobalantidium coli are asymptomatic in most hosts. In humans and captive African great apes clinical infections occasionally occur, manifested mainly by dysentery; however, factors responsible for development of clinical balantidiasis have not been fully clarified. We studied the effect of dietary starch on the… (More)
