The Gastrointestinal Parasites in Habituated Group of Sulawesi Black-crested Macaque (<i>Macaca nigra</i>) in Tangkoko, North Sulawesi

The Sulawesi black-crested macaque (Macaca nigra) is an endemic primate of North that categorized as critically endangered (IUCN 2015). Endoparasite contributes to the decline M.nigra. Therefore, this study aims determine prevalence endoparasites in (M. nigra). We collected 80 fresh fecal samples representing all sex from two habituated groups. analyzed them using direct examination technique (0.9% NaCl, iodine, methylene blue) and flotation with modified McMaster test. A total 15 endoparasite taxa were recorded 78 infected at least one or several taxa. Around 93.75% (75/80) positive for protozoa (Balantidium sp., Entamoeba Giardia Isospora sp.) 88.75% (71/80) helminths (Ancylostoma Strongyloides Haemonchus Trichuris Trichostrongylus Ascarid Diphyllobothrium Echinococcus Hymenolepis Schistosoma japonicum mekongi). abundance was higher than helminth, although number helminth taxon (11) higher. average temperature monthly rainfall did not affect (EPG). females males due different social styles; female crested macaques are more tolerant males. group a larger individuals had endoparasites. These results confirm presence high diversity gastrointestinal M. nigra, which can help understand transmission dynamics zoonotic potential, well consider conservation policies.
