Alimentary tract parasites of vervet monkeys (Cercopithecus aethiops): A potential reservoir for human transmission

Monkeys are important experimental models for investigating human diseases. the aim of this study was to survey the alimentary tract parasites among imported vervet monkeys (cercopithecus aethiops) to iran. fecal samples were collected from 40 vervets imported from tanzania to razi vaccine and serum research institute of iran. fecal samples were assessed by direct smear and telman sedimentation methods. the results of microscopic examination demonstrated that all (100%) the animals were infected with different alimentary tract parasites. the protozoan parasites comprised of iodamoeba butschlii (85%),entamoeba coli (72.5%),entamoeba histolytica/dispar (37.5%),chilomastix mesnili (12.5%),balantidium coli (10%),blastocystis hominis (7.5%),and giardia intestinalis (5%). additionally,eggs of some helminths,including physaloptera caucasica (27.5%),trichostrongylus spp. (7.5%),trichuris trichiura (7.5%),bertiella spp. (2.5%),and strongyloides fulleborni (2.5%),were detected. the presence of gastrointestinal parasites in vervets poses a risk for human or experimental results. thus,the diagnosis and treatment of these parasites should be considered before any laboratory assay. © 2016 by razi vaccine and serum research institute.
