Parásitos intestinales en monos congo <i>Alouatta palliata</i> (Primates: Cebidae) de Costa Rica

Abstract

Intestinal parasites in howler monkeys Alouatta palliata (Primates: Cebidae) of Costa Rica. Fecal samples of 102 howler monkeys (Alouatta palliata) from several sites of Costa Rica were studied for intestinal parasites. The zones studied were: Central Valley (San Ramón, Alajuela), Central Pacific (Chomes and Manuel Antonio National Park, Puntarenas), North Pacific (Palo Verde Park and Playa Potrero, Guanacaste), Chira Island in the Nicoya Gulf and Caribean area (Cahuita, Limón). Animals were anesthetized with dards containing Telazol in order to collect the fecal material; some monkeys defecated spontaneously and others by direct stimulation. Samples were studied in saline solution (0.85%) and a Iodine solution, or stained with Haematoxylin. The material was also cultured in Dobell culture medium to determine the presence of amoeba and flagellates. Strongyloides, Controrchis, Trypanoxyuris genera were found in 3.4% of the samples. In addition 16.7% to 80% of the animals showed protozoa infection with Endolimax, Entamoeba, Trichomonas and Giardia. It is discussed the relationships of parasite infection with environmental conditions, animal population and human presence, specially in the monkey conservation programs point of view. Rev. Biol.

A Coprological Survey of Parasites in White-Faced Capuchins (Cebus capucinus) from Sector Santa Rosa, ACG, Costa Rica

“…Although the difference in parasite species richness between the current capuchin study and the majority of the howler studies [Stuart et al, 1990;Stoner, 1996;Stuart et al, 1998;Phillips et al, 2004;Chinchilla et al, 2005;Eckert et al, 2006;Stoner and González Di Pierro, 2006;TrejoMacías et al, 2007;Kowalzik, 2009;Cristóbal-Azkarate et al, 2010;Valdespino et al, 2010] may be a result of differential sampling intensity, it seems that different howler species and populations are infected with the same small set of directly transmitted parasites (Giardia, Entamoeba, Trypanoxyuris, Strongyloides) . Conversely, capuchins appear to be exposed to a wide range of directly and indirectly transmitted parasites.…”

“…Wild Cebus and Alouatta are hosts to a number of the same parasite genera including Strongyloides and Giardia [Stuart et al, 1998;Chinchilla et al, 2005;Stoner References and González Di Pierro, 2006;Chinchilla et al, 2007;Cristóbal-Azkarate et al, 2010;Kowalzik et al, 2010], and although the parasites of spider monkeys are not well known, they are hosts for Strongyloides as well [Karesh et al, 1998;Carrasco et al, 2008].…”

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

“…Human population movements and activities, and introductions of domestic animals may introduce new parasitic organisms to remote regions , negatively affecting the health of primates. Uakari populations in the Yavari basin are currently affected by logging and hunting, but our studied group, in the Lago Preto Conservation Concession, suffers little human disturbance.…”

Parásitos gastrointestinales en el mono choro cola amarilla (Lagothrix flavicauda) de vida silvestre en el distrito Corosha, Amazonas, Perú

“…Se reconoce que la presencia de protozoarios en primates podría estar relacionada a un mayor contacto con poblaciones humanas (Fernández, 2011;Philips et al, 2004). En el presente estudio se encontró Entamoeba coli, que por su presencia en anteriores reportes en primates de vida silvestre en zonas con perturbación antropogénica (Stuart et al, 1998;Philips et al, 2004;Chinchilla et al, 2005), es considerado en el mono choro común un parásito comensal (Stuart et al, 1998;Chinchilla et al, 2005;Fernández, 2011). Cryptosporidium sp ha sido reportado también en Alouatta, Ateles, Cebus, Saimiri, Saguinus y Aotus (Gozalo y Tantaleán, 1996;Guerrero et al, 2012).…”
