Intestinal helminths in wildPeruvian red uakari monkeys(Cacajao calvus ucayalii)in the northeasternPeruvianAmazon

Abstract

Parasites are important in the management of the health of primate populations. We examined 36 fecal samples from Peruvian red uakari monkeys (Cacajao calvus ucayalii) collected from wild animals in the northeastern Peruvian Amazon. Samples were positive for helminth infection. Nematodes egg: Strongyloididae, Trypanoxyuris sp., Spirurid, and a cestode egg were identified.

“…The species is included in Appendix II of CITES (the Convention on International Trade in Endangered Species of Wild Fauna and Flora) and is described as Vulnerable by IUCN (International Union for Conservation of Nature), mainly due to habitat loss and hunting (Peres, 2001; Veiga & Bowler, 2013). This rareness makes the collection of data on red uakari biology difficult and, until now, parasitological studies have been restricted to faecal samples (Conga et al , 2014). We report on the nematodes found in the large intestine of Peruvian red uakari monkeys on the Yavari-Mirín River and describe new species.…”

Balantidium coli and other gastrointestinal parasites in captives non‐human primates of the Rio de Janeiro, Brazil

“…Although there are various studies about gastrointestinal parasitosis in simians, there are few reports about it in captive primates and neotropical species . Most studies are directed to great apes , to the catarrhini , to neotropical species living in the wild , and to animals confined in zoological gardens . In this context, this study aimed to evaluate the estimated prevalence of gastrointestinal parasites of captive non‐human primates of two breeding centers, one for public health research and the other for species conservation, both located in Rio de Janeiro State, correlating the positivity of parasitosis, as well as the frequency of Balantidium coli trophozoites, among the various species of those animals.…”

A multiyear survey of helminths from wild saddleback (Leontocebus weddelli) and emperor (Saguinus imperator) tamarins

“…Two common nematodes in tamarins with similar egg morphology are Trypanoxyuris spp. (Carrasco, Tantaleán, Gibson, & Williams, 2008;Conga et al, 2014;Guerrero et al, 2012;Stone et al, 2016;Thatcher & Porter, 1968) and Trichospirura leptostoma (Orihel & Seibold, 1971;Vicente et al, 1992;Vicente, de Oliviera Rodrigues, Corrêa Gomes, & Pinto, 1997). Other parasites with similar ova occasionally reported in New World nonhuman primate species are Physaloptera dilatata and Longistriata dubia.…”

“…Eggs are ellipsoidal, with a smooth thin shell, and larvated. Suspect genus Strongyloides, possibly S. cebus (Cogswell, 2007;Conga et al, 2014;Guerrero et al, 2012;Mati, Junior, Pinto, & de Melo, 2013;Parr, Fedigan, & Kutz, 2013;Stone et al, 2016).…”
