A survey for intestinal helminths in recently wild-caught Macaca mulatta and results of treatment with mebendazole and thiabendazole.

One hundred Macaca mulatta, trapped in India and transported directly to the California Primate Research Center, were surveyed for the prevalence of gastrointestinal helminths. Trichostrongylus sp. was found in 86% of the animals, followed by Strongyloides fulleborni (63%), Streptopharagus sp. (38%), Oesophagostomum sp. (23%) and Anatrichosoma sp. (21%). Treatment with mebendazole and thiabendazole was efficacious against all the intestinal nematodes, with the exception of mebendazole versus Streptopharagus sp.
