“…Again, Murshidia species are only otherwise known from elephants, rhinoceroses, and suids (Anderson, 1992). The host ranges and possible origins of the two seemingly common trichostrongyles are discussed by Durette-Desset et al (1992): their closest relatives are parasites of herbivores unrelated to primates. Of all the parasites shown in this and previous studies to be normal components of the gorilla endofauna, only Oesophagostomum spp.…”

“…The dead female contained numerous specimens of Paralibyostrongylus kalinae and Hyostrongylus kigeziensis, two trichostrongyles described by Durette-Desset et al (1992). In addition, numerous specimens of the larger strongyles Oesophagostomum stephanostomum and Murshidia devians were found in approximately equal numbers.…”

The intestinal parasite fauna of the mountain gorillas of Bwindi—Impenetrable Forest, Uganda was studied by means of faecal examination and a single post‐mortem. The fauna was remarkably uniform between social groups and individuals, showing only slight differences between age groups; there is no evidence of any interaction between the parasites observed. The only protozoa were entodiniomorph ciliates; amoebae and flagellates were absent. Helminths included a single host‐specific cestode species and at least five nematodes, three of which are hostspecific. The closest relatives of the host‐specific parasites are found in ungulates and paenungulates, not in hosts phylogenetically related to the gorilla. This unique and specialized parasite fauna deserves to be monitored so that any effects of the habituation of the gorillas for tourism can be assessed.

Intestinal Parasites of Free-ranging, Semicaptive,and Captive Pongo abelii in Sumatra, Indonesia

We collected fecal samples from 32 free-ranging, 19 semicaptive, and 54 captive Sumatran orangutans on Sumatra from 1998 until 2004 and screened them for gastrointestinal parasites. Our objectives were to compare the intestinal parasites of free-ranging, semicaptive, and captive orangutans and to evaluate the risk of parasite transmission in orangutan reintroduction programs. We identified 4 genera of Protozoa, 7 genera of nematodes, 1 trematode sp., and 1 cestode sp. The prevalence of Balantidium coli in free-ranging orangutans was significantly higher than in captive individuals. However, the prevalence of Strongyloides sp. was higher in captive than in free-ranging orangutans. Free-ranging female orangutans had a significantly higher total prevalence of intestinal parasites than that of males. We found no significant difference between parasite prevalences in different age groups. Compared to gorillas and chimpanzees, orangutans carry a smaller variety of protozoan and nematode species. Strongyloides sp. infections form the highest risk in reintroduction programs as crowding, ground-dwelling, and poor hygiene in captive and semicaptive orangutans may cause a constant reinfection.

Mountain gorillas (Gorilla gorilla beringei) are critically endangered, remaining only in two isolated populations in Central Africa. The objective of this study was to determine the prevalence and intensity of intestinal parasites in a single group of mountain gorillas in Bwindi Impenetrable National Park, Uganda over 7 weeks from June to August 2000. Fecal samples were collected from night nests and transported in formalin for examination at Cornell University and the Centers for Disease Control. All fecal samples were examined microscopically for parasitic larvae, cysts, and eggs. The following were found: strongylid eggs, Probstymaria sp. larvae, and two parasitic nematode larvae that were not identified. Additional examination techniques will be used to further examine the fecal material specifically for protozoan cysts. An increasing threat to this group of gorillas is the presence of local field assistants and researchers. We found no evidence of human parasites in the fecal samples from this gorilla group.
