     The White-footed tamarin (Saguinus leucopus) is an endangered species endemic to North-west Colombia. Although there is an ongoing conservation plan, there has not been any systematic study of the population structure, ecological interactions or natural history of this species. This study aims to identify the most prevalent blood and fecal parasites and determine hematological and serum biochemistry values in free-ranging tamarins. Peripheral blood and feces have been collected from 30 individuals distributed in five social groups in the Colombian department of Antioquia. The general physical condition of most individuals is good. They are free of ectoparasites and only one individual displayed a posterior cervical lesion with purulent secretion that was probably caused through aggression. Fifty seven percent and 43% of all blood samples tested so far have shown infection with Microfilaria spp. and Trypanosoma spp., respectively. Preliminary analysis of fecal samples has revealed the presence of Prosthenorchis spp. (57%), Uncinaria spp. (40%), Strongylus spp. (30%), Trichustrongylus spp. (30%), Taenia spp. (7%), Ascaris spp. (3%) and protozoa (10%). Relative to previous reports for captive individuals, cell counts of white blood cells and neutrophils are high, which could be associated to parasitemias and increased immunological challenge in natural populations. The geographic coverage and sample size is currently being increased, which will allow more detailed analysis of blood parameters and infections in relation to sex, age and geography.
