A survey for Anatrichosoma (Nematoda: Trichinellida) in wild-caught Macaca mulatta.

: One hundred rhesus monkeys which were captured from two geographical sites were tested for Anatrichosoma, a nematode that lives in the nasal passages. The monkeys were tested using both fecal examinations and nasal swabs. Three percent of the monkeys from one site were positive, and 68% from the other site were positive. Twenty-one percent of the animals tested by fecal examination were positive and 48% were positive using nasal swab examination.
