Gastrointestinal parasites in gray langurs (Semnopithecus entellus)

Non-human primates are potential source and natural reservoir of parasitic infections of public heath importance. This paper discusses the gastrointestinal parasites of zoonotic importance in gray langurs (Semnopithecus entellus) and their therapeutic management. Laboratory examination of faecal samples of gray langurs received from Teaching Veterinary Clinical complex, Gannavaram revealed the presence of adult Strongyloides spp., larvae of S. stercoralis, eggs of S. fuelleborni, Trichuris trichiura, and cysts of Entamoeba sp. After confirmatory diagnosis monkeys were treated with injectable ivermectin 0.2 mg kg⁻¹ subcutaneously and metronidazole 25 mg kg⁻¹ intravenously along with supportive therapy. The animals recovered clinically on day two. The results of the study emphasize the need of contact persons be aware of the risk of parasitic zoonoses from wild animals-
