“…Since that time, collaborative efforts of Brazilian and foreign governmental and nongovernmental organizations (Mallinson 2001;Ryland et al 2002) resulted not only in stabilization of their extinction risk but also in lowering it for the GLT (IUCN 2004). Recent findings (Monteiro et al 2003(Monteiro et al , 2006(Monteiro et al , 2007 suggest that these advances may be compromised by parasitic diseases capable of reducing the size and alter structure of populations of GLTs, as has been described for other wild animals (Hudson et al 1998). This is especially true if they are in patchy environments (McCallum and Dobson 2002), genetically depleted, or exposed to new emerging infectious agents by deforestation (Patz et al 2004;Horwitz and Wilcox 2005;Travis et al 2006).…”

“…Helminth prevalences of these three species varied with tamarin sex, age, and helminth transmission strategy, as well as GLT population provenance (Monteiro et al 2007). Helminth infections in other mammal species were capable of modulating the immune response (Jenkins et al 2005;Helmby and Bickle 2006) and/or lowering their environmental fitness (Gulland 1995).…”

The parasite prevalence and infection intensity in primate wild populations can be affected by many variables linked to host and/or parasite ecology or either to interparasite competition/mutualism. In this study, we tested how host sex, age, and place of origin, as well parasitic concomitant infections affect the structure of golden lion and golden-headed lion tamarins parasite community, considering Trypanosoma cruzi and intestinal helminths infection in these primates. A total of 206 tamarins from two Atlantic Coastal rain forest areas in Brazil were tested during 4 years for prevalence of T. cruzi infection and helminth prevalence. Three intestinal helminth groups showed high prevalences in both tamarin species: Prosthenorchis sp., Spiruridae, and Trichostrongylidae. An association between presence of T. cruzi infection and higher intestinal helminth prevalence was found in both tamarin species. Two explanations for this association seem to be plausible: (1) lower helminth-linked mortality rates in T. cruzi-infected tamarins and (2) lower elimination rates of helminths in such tamarins. A higher frequency of T. cruzi-positive blood cultures was significantly correlated to female tamarins and to the presence of Trichostrongylidae infection. The possibility of an increase in the transmissibility of T. cruzi and the three analyzed helminths in lion tamarins with concomitant infections is discussed.

“…These groups had to be combined due to small sample sizes, but it is likely that aggregation would be reduced if each group were examined separately. As was reported for tamarins (Monteiro et al 2007a), female Japanese macaques also showed higher aggregation levels than did males, possibly suggesting greater exposure and/or susceptibility in general among the latter. The same may be said of high-ranking relative to low-ranking females.…”

“…Interestingly, this appears to be the only study published in a journal dedicated to the study of primates focusing on such parasite population processes. Finally, Monteiro et al (2007a) provide the only study of parasite aggregation in a primate host (golden lion tamarins, Leontopithecus rosalia) using relatively modern methods: they estimated the dispersion parameter (k) of the negative binomial distribution (the theoretical distribution that best approximates macroparasite distributions across a wide range of hosts (Shaw et al 1998)), using the estimator provided in Wilson et al (2002). Not only were all parasite distributions found to be aggregated, as they were in each of the above-mentioned studies, Monteiro et al (2007a) further demonstrate a sex bias, such that the degree of aggregation was higher among females than among males, though they could only speculate as to what might have caused this pattern.…”

The establishment of baseline data on parasites from wild primates is essential to understand how changes in habitat or climatic disturbances will impact parasite-host relationships. In nature, multiparasitic infections of primates usually fluctuate temporally and seasonally, implying that the acquisition of reliable data must occur over time.Individual parasite infection data from two wild populations of New World primates, the saddleback (Leontocebus weddelli) and emperor (Saguinus imperator) tamarin, were collected over 3 years to establish baseline levels of helminth prevalence and parasite species richness (PSR). Secondarily, we explored variation in parasite prevalence across age and sex classes, test nonrandom associations of parasite co-occurrence, and assess the relationship between group size and PSR. From 288 fecal samples across 105 individuals (71 saddleback and 34 emperor tamarins), 10 parasite taxa were identified by light microscopy following centrifugation and ethyl-acetate sedimentation. Of these taxa, none were host-specific, Dicrocoeliidae and Cestoda prevalences differed between host species, Prosthenorchis and Strongylida were the most prevalent. Host age was positively associated with Prosthenorchis ova and filariform larva, but negatively with cestode and the Rhabditoidea ova. We detected no differences between expected and observed levels of co-infection, nor 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 and species predicted the presence of four and three parasite taxa, respectively, with saddleback tamarins exhibiting higher PSR. Now that we have reliable baseline data for future monitoring of these populations, next steps involve the molecular characterization of these parasites, and exploration of linkages with health parameters.
