Parásitos en monos carablanca Cebus capucinus (Primates: Cebidae) de Costa Rica

fecal samples of 53 white face monkeys (cebus capucinus) from some sites of costa rica were studied for blood and intestinal parasites. animals were anesthetized with darts containing telazol, blood and fecal samples were collected and all the material was studied in the laboratory. for blood parasites, giemsa stain andknott concentration was performed. intestinal parasites were studied by direct examination in 0,85% saline solution and a iodine solution. haematoxylin stain was used for better protozoa identification. strongyloides sp, hookworms, acanthocephalid eggs and other nematodes, as well as tritrichomonas sp (more frequent) and other protozoa were found. the presence of at least one parasites was observed in 33.3% to 100% of the fecal samples with an average of 73.6%. there was not any correlation between sex and infection rate, but the presence of parasite was higher in heavier (older) animals. microfllarias were the only blood organism detected.the reasons for these high infection rates could be explained for feed diversity, contaminated soil and water contact and sociability of these animals, among other factors.
