Helminthic and protozoan coinfections in mona monkeys (Cercopithecus mona) at Batu Secret Zoo, Batu, East Java, Indonesia

This case report originated from fecal examination of six mona monkeys, which lived together in a cage. The helminth eggs from the feces were evaluated microscopically using the native method. Six eggs of Trichuris sp. were found, and the monkeys were subsequently treated with Curcuma Plus® orally for 3 days, combined by 3 days of fenbendazole orally. On the 6th day, no Trichuris sp. eggs were found; however, Entamoeba sp. cysts were discovered. No Entamoeba sp. cysts were identified on day 13. Helminthic infections will frequently dominate during protozoal and helminthic co-infection stages. A protozoal infection can be recognized after the helminth infection, which was treated with anthelmintics.
