- Abstract
The non-human primates have a huge amount and diversity of parasites; however, the information in this area around the world is scarce and inconsistent. In South America, where there is a minimal epidemiological surveillance, it is difficult to recognize the role of multiple parasites and their population dynamic. In the Valley of Magdalena natural forest coverage has been reduced to 15%, and as a consequence, the parasite-host relation dynamic has been altered. The aim of this study was to understand the effect of habitat reduction and fragmentation on Neotropical primates considering sanitary parameters. For this purpose, the prevalence of intestinal parasites in Red-howler monkeys and in Brown-spider monkeys in two forest fragments within the grassland matrix used for extensive livestock was determined. The diagnosis of parasitic infections was done using flotation techniques and direct observation. The prevalence estimation was done using Bayesian analytic techniques. In this case study 75% (21/28) of the fecal samples were positive to the presence of parasite forms. The biologic presence of forms compatible with Strongyloides stercoralis, Cryptosporidium parvum and Cyclospora cayetanensis was reported. There was no significant difference between primate species in both places, but a high prevalence of Strongyloides stercoralis (27%-59%) is reported. The parasite presence suggests a potential risk to public health and a threat for the Atelidos populations. The habitat reduction and fragmentation probably increases parasite transmission (animal- animal) associated with the parasite capacity to transmit, reproduce and resist environmental pressure and host immunity.
