Occurrence of gastrointestinal(GI)parasites in captive Olive Baboon and Common Langur in Bangladesh

Non-human primates(NHPs)serve as necessary reservoir hosts of parasites that create diseases to human.A close interaction between human and NHP can make a pathway for transmission of zoonotic diseases.To prevent zoonotic infection of zoo keepers,park visitors as well as keeping the captive NHPs in healthy state,it is necessary to carry out regular parasitological examination and treatment.A total of 72 fecal samples of Olive Baboon(n=39)and Common Langur(n=33)irrespective of their age and sex were collected from two zoological gardens of Bangladesh.Eggs and oocysts of seven gastrointestinal(GI)parasites were observed and identified in samples of both host species.The prevalence of GI parasites recorded was 100%.In case of Olive Baboon,the protozoan prevalence was higher(53.83%)than that of helminths,but opposite scenario was seen in case of Common Langur.Besides,higher intensity of coccidian oocysts in both hosts was recorded in the study.
