“…However, the five samples (7.1%), in which Plasmodium was identified through optical microscopy, were not positive according to PCR. Duarte et al (2006Duarte et al ( , 2008 also identified divergences between the microscopy and PCR techniques in samples from NHP. The positive results obtained from the first technique were not confirmed from the second one.…”

“…Moreover, in Brazil, in a study on neotropical primates in two different biomes, the Atlantic forest (n = 71, positivity = 12.6%) and the semi-deciduous Atlantic forest (n = 235, positivity = 6.7%), the greatest positivity was for P. malariae/P. brasilianum: 5.6% and 5.5%, respectively (DUARTE et al, 2006). Recent data obtained by Bueno et al (2013) with Amazonian primates, assure that P. malariae is the most commonly species found in the animals belonging to this area.…”

“…Approximately 200 species are known, among which 33 parasitize nonhuman primates of the Old and New Worlds (EYLES, 1963;LECLERC et al, 2004). However, in South America, only two species of Plasmodium have been described infecting NHP naturally (P. brasilianum and P. simium) and Brazil is currently the only country in which both species occur (DUARTE et al, 2006). P. simium has been diagnosed in Alouatta fusca, Alouatta guariba and Brachyteles arachnoides from areas of the Atlantic Forest biome, in southern and southeastern Brazil.…”

The states that make up the Legal Amazon Region, which include the state of Maranhão, account for 99% of registered cases of human malaria in Brazil. It is also believed that transmission of malaria from nonhuman primates (NHP) to humans occurs in this region, because of current reports of seroepidemiological results from samples from humans and NHP coexisting in the same areas. This study aimed to make morphological, serological and molecular diagnoses of Plasmodium spp. in neotropical primates on the island of São Luís, state of Maranhão, Brazil. The diagnostic techniques used were optical microscopy, the polymerase chain reaction (PCR) and the indirect immunofluorescence assay (IFA). From June 2009 to April 2010, 70 NHP were sampled: 50 at the Wild Animal Screening Center (CETAS), located in the municipality of São Luís and 20 free-living individuals that were caught in a private reserve located in the municipality of São Jose de Ribamar, state of Maranhão. Under an optical microscope, 140 slides (two from each animal) were evaluated and five animals (7.1%) were found to be positive. IFA did not detect anti-Plasmodium spp. From PCR on the 70 animals sampled, amplified Plasmodium spp. products were observed in 13 samples, of which eight (61.5%) were from free-living animals and five (38.5%) were from animals at CETAS.

“…The same conjugate was used in malaria studies and was able to detect IgG antibodies against sporozoite proteins (infective forms of Plasmodium species) in neotropical monkey blood samples 7,11,27 . Despite a possible loss in the test sensitivity, since it was used in a high concentration, the conjugate was competent to discriminate positive and negative sera, allowing its use in epidemiological studies.…”

SUMMARYYellow fever (YF) is an acute viral infectious disease transmitted by mosquitoes which occurs in two distinct epidemiological cycles: sylvatic and urban. In the sylvatic cycle, the virus is maintained by monkey's infection and transovarian transmission in vectors. Surveillance of non-human primates is required for the detection of viral circulation during epizootics, and for the identification of unaffected or transition areas. An ELISA (enzyme-linked immunosorbent assay) was standardized for estimation of the prevalence of IgG antibodies against yellow fever virus in monkey sera (Alouatta caraya) from the reservoir area of Porto Primavera Hydroelectric Plant, in the state of São Paulo, Brazil. A total of 570 monkey sera samples were tested and none was reactive to antibodies against yellow fever virus. The results corroborate the epidemiology of yellow fever in the area. Even though it is considered a transition area, there were no reports to date of epizootics or yellow fever outbreaks in humans. Also, entomological investigations did not detect the presence of vectors of this arbovirus infection. ELISA proved to be fast, sensitive, an adequate assay, and an instrument for active search in the epidemiological surveillance of yellow fever allowing the implementation of prevention actions, even before the occurrence of epizootics.
