AbstractNoninvasive monitoring of gastrointestinal parasites from wild primates demonstrates that parasite-host relationships are altered during habitat or climatic disturbances. Interpreting changes in parasite measures for population health monitoring is problematic, since wild primates are infected with multiple parasites that fluctuate temporally and seasonally. Individual parasite infection data from two wild populations of New World primates, the saddleback (Leontocebus weddelli) and emperor (Saguinus imperator) tamarin, were collected over three years to: 1) establish baseline levels of parasite species richness (PSR) and variation across demography; 2) test for non-random associations of parasite co-occurrence; and 3) test hypothesized relationships between group size and PSR. Ten distinguishable parasite taxa were identified from 288 fecal samples by light microscopy following centrifugation and ethyl-acetate sedimentation. These samples represented 105 unique individuals (71 saddleback and 34 emperor tamarins), across 13 saddleback and seven emperor groups. Of the parasites identified in this study, none were confirmed as host specific, and only two parasites had statistically different prevalence between the host species. With few exceptions, individual infection status remained relatively unchanged over the study period. Considering yearly pair-wise parasite associations, we detected no marked differences between expected and observed levels of co-infection, nor did we detect statistically significant associations between group size and parasite species richness over 30 group-years. Logistic models of individual infection status did not identify a sex bias; however, age or species predicted the presence of four and three parasite taxa, respectively. Our model found higher PSR for saddleback tamarins. Considering the two most common parasites, one is typically pathogenic and the other is not, reinforcing caution when translating clinical findings of pathology to real-world systems. We now have reliable baseline data for future monitoring of these populations. Next steps should involve the molecular characterization of these parasites, and the exploration of linkages with health parameters.
