“…Recently, many studies have been performed to evaluate the presence of malaria parasites in NHPs, both in the Atlantic Forest and Amazon regions, aiming to understand their roles as reservoirs of malaria [ 4 , 7 , 8 , 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 ]. Some serological studies have also been carried out with the same aim but without using any P. malariae erythrocytic stage antigens [ 9 , 10 , 25 ].…”

Non-human primates (NHPs) have been shown to be infected by parasites of the genus Plasmodium, the etiological agent of malaria in humans, creating potential risks of zoonotic transmission. Plasmodium brasilianum, a parasite species similar to P. malariae of humans, have been described in NHPs from Central and South America, including Brazil. The merozoite surface protein 1 (MSP1), besides being a malaria vaccine candidate, is highly immunogenic. Due to such properties, we tested this protein for the diagnosis of parasite infection. We used recombinant proteins of P. malariae MSP1, as well as of P. falciparum and P. vivax, for the detection of antibodies anti-MSP1 of these parasite species, in the sera of NHPs collected in different regions of Brazil. About 40% of the NHP sera were confirmed as reactive to the proteins of one or more parasite species. A relatively higher number of reactive sera was found in animals from the Atlantic Forest than those from the Amazon region, possibly reflecting the former more intense parasite circulation among NHPs due to their proximity to humans at a higher populational density. The presence of Plasmodium positive NHPs in the surveyed areas, being therefore potential parasite reservoirs, needs to be considered in any malaria surveillance program.

“…Currently, there is scarce knowledge regarding the factors that threaten neotropical primates, when compared to Old World primates 5,9,10 . Although reports of diseases outbreaks in neotropical primates are relatively common, 11‐14 long‐term studies on mortality and causes of death of these species are scarce 7 . In this study, we aimed to determine the frequency and discuss the main causes of death in neotropical primates during an 18‐year period in the Rio Grande do Sul state, Southern Brazil.…”

Background Anthropogenic disturbances are the main threats to nonhuman primates conservation, and infectious diseases may also play a key role in primate population decline. This study aimed to determine the main causes of death in neotropical primates. Methods A retrospective study of post‐mortem examinations was conducted on 146 neotropical primates between January 2000 and December 2018. Results Conclusive diagnoses were obtained in 68.5% of the cases, of which 59 corresponded to non‐infectious causes and 41 to infectious diseases. Trauma was the main cause of death (54/100), with anthropogenic stressors caused by blunt force trauma injuries (collision with vehicles) and puncture wound injuries associated with interspecific aggression (dog predation) were the most common factors. Other causes of death included bacterial diseases (27%), followed by parasitic diseases (12%), neoplasms (2%), and viral diseases (2%). Conclusions Free‐ranging primates were mostly affected by non‐infectious causes, while captive primates were by infectious conditions.

“…Forest fragmentation is one of the main factors threatening NHPs [8], affecting all but not only the six Neotropical species included into the World's 25 Most Endangered NHPs List [112]. However, only two studies included in the present review accounted for forest fragmentation as a variable during the analyses [25,45], even if some were performed in fragmented areas [67,81,85,91,105]. We strongly encourage the inclusion of this crucial factor as a variable for future studies as a way of better understanding parasite ecology, taking into account that some studies had reported a higher parasite prevalence in NHPs living in fragmented habitats [62,118], while other authors had found a lower presence of parasites [69], in comparison to prevalence found in continuous forests.…”

Parasites of Free-Ranging and Captive American Primates: A Systematic Review

et al. 2021

The diversity, spread, and evolution of parasites in non-human primates (NHPs) is a relevant issue for human public health as well as for NHPs conservation. Although previous reviews have recorded information on parasites in NHPs (Platyrrhines) in the Americas, the increasing number of recent studies has made these inventories far from complete. Here, we summarize information about parasites recently reported in Platyrrhines, attempting to build on earlier reviews and identify information gaps. A systematic literature search was conducted in PubMed, ISI Web of Science, and Latin American and Caribbean Health Sciences Literature (LILACS), and following the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines. Ninety-three studies were included after the screening process. Records for 20 genera of NHPs, including 90 species were found. Most of the studies were conducted on captive individuals (54.1%), and morphological approaches were the most used for parasite identification. The most commonly collected biological samples were blood and stool, and Protozoa was the most frequent parasite group found. There is still scarce (if any) information on the parasites associated to several Platyrrhine species, especially for free-ranging populations. The use of molecular identification methods can provide important contributions to the field of NHPs parasitology in the near future. Finally, the identification of parasites in NHPs populations will continue to provide relevant information in the context of pervasive habitat loss and fragmentation that should influence both human public health and wildlife conservation strategies.
