The Brazilian Cerrado fauna shows very wide diversity and can be a potential viral reservoir. Therefore, the animal's susceptibility to some virus serve as early warning signs of human diseases. Moreover, wild animal virome this biome is unknown. Based on scenario, high-throughput sequencing contributes robust tool for identification known unknown species in environment. In present study, faeces samples from cerrado birds (Psittacara leucophthalmus, Amazona aestiva, Sicalis flaveola) mammals...
Although malaria cases have substantially decreased in Southeast Brazil, a significant increase the number of Plasmodium vivax-like autochthonous human has been reported remote areas Atlantic Forest past few decades Rio de Janeiro (RJ) state, including an outbreak during 2015-2016. The singular clinical and epidemiological aspects several cases, collectively with molecular genetic data, revealed that they were due to non-human primate (NHP) parasite simium; however, understanding malarial...
In the last decade, Flaviviruses such as yellow fever (YFV) and Zika (ZIKV) have expanded their transmission areas. These viruses originated in Africa, where they exhibit both sylvatic interhuman cycles. Brazil, risk of YFV urbanization has grown, with approaching most densely populated metropolis, while concern about ZIKV spillback to a cycle risen. To investigate these health threats, we carried out extensive collections arbovirus screening 144 free-living, non-human primates (NHPs) 5219...
Chikungunya virus (CHIKV) is primarily associated with non-human-primates (NHPs) in Africa, which also infect humans. Since its introduction to Brazil 2014, CHIKV has predominantly thrived urban cycles, involving Aedes aegypti mosquitoes. Limited knowledge exists regarding occurrence and implications rural sylvatic cycles where neotropical NHPs are potential hosts, from we highlight Leontopithecus chrysomelas (Kuhl, 1820), the golden-headed lion tamarin (GHLT), an endangered species endemic...
ABSTRACT Brazil harbors the greatest diversity of primates, and among them, genus Callithrix is notable for its adaptation to urban environments. Despite being endemic southern Bahia northeastern Minas Gerais, Wied's marmoset ( kuhlii ) remains understudied, highlighting need baseline health data. This study aimed characterize hematological biochemical profiles C. in peri‐urban areas within distribution range. A total 106 wild marmosets were captured, blood samples collected from femoral...
Aim: This work represents the first reported investigation on effects of magnetic nanoparticles (MNPs) in nonhuman primates. Biodistribution, biocompatibility and nanotoxicity maghemite stabilized with dimercaptosuccinic acid (DMSA) were accessed. Materials & Methods: A control animal was used three other animals intravenously injected DMSA-MNPs euthanized 12 h, 30 90 days following administration. Extracted organs processed by histological techniques. An additional to collect blood samples...
Howler monkey capture is an arduous and expensive task requiring trained specialized professionals. We compared strategies methods to most efficiently Alouatta guariba clamitans in remnants of the Atlantic Forest Rio de Janeiro its bordering states Minas Gerais São Paulo. tested whether or not success expeditions forest with anesthetic darts, nets, baited traps differed without support information network, a contact chain built key institutions inhabitants continuously monitor howler...
Leucism is the lack or reduction in pigmentation most parts of body, but not eyes and body extremities. It extremely rare primates has never been reported for Callithrix , a genus endemic to Brazil. We searched individuals jacchus C. penicillata with anomalies systematic survey three protected areas Atlantic Forest, within museum collections Brazil, opportunistically during field studies. Since 2008, we have recorded 8 leucism small urban periurban forest patches. Four were from native...
Animals in captivity should receive adequate sunlight exposure for sufficient generation of vitamin D [25(OH)D]. In the present study, 25(OH)D serum levels 84 Callithrix penicillata primates were evaluated.To determine those animals; to evaluate influence gender and period on their levels.Three groups evaluated: group 1 (n = 29) free exposure; 2 34) partial 3 21) without exposure.The obtained values were: 1, 121.2 +/- 33.3 ng/ml; 2, 115.2 32.2 3, 53.3 10.4 ng/ml. Significant statistical...
Zoonotic infections with epidemic potential, as non-human primate malaria and yellow fever (YF), can overlap geographically. Optimizing a small blood sample for diagnosis surveillance is of great importance. Blood are routinely collected YF clots usually discarded after serum obtention. Aiming to take advantage, the sensitivity PCR using extracted DNA from long-term frozen human primates detection Plasmodium spp. in low parasitaemia conditions was assayed. Malaria generated results agreement...
Abstract Background Vitamin D is a secosteroid hormone with important roles in the control of bone and mineral metabolism vertebrates maintenance systemic homeostasis. This study aimed (i) to evaluate serum concentrations 25‐hydroxy‐vitamin levels [25( OH ) ], parathyroid ( PTH ionized calcium (i C a) wild allithrix penicillata (black‐tufted marmosets) (ii) propose reference ranges for those analytes free‐living marmosets. Methods Blood samples were collected from 15 animals analyzed 25( , i...
The genus Orthopoxvirus (OPXV) of the family Poxviridae comprises several viruses that are capable infecting a wide range hosts. One most widespread OPXVs is Vaccinia virus (VACV), which circulates in zoonotic cycles South America, especially Brazil, domestic and wild animals humans causing economic losses as well impacting public health. Despite this, little known about presence and/or exposure neotropical primates to orthopoxviruses country. In this study, we report results search for...

 A translocação de primatas ameaçados extinção é uma ferramenta manejo que envolve o resgate grupos ou indivíduos isolados e/ou reforço populações em declínio, visando a conservação das espécies. O muriqui-do-norte (Brachyteles hypoxanthus) se encontra criticamente perigo com população total estimada aproximadamente 1,000 indivíduos. ausência conectividade entre as áreas sua ocorrência leva ao isolamento e, consequentemente, fêmeas migram busca um novo grupo. Nós...
The Atlantic Forest Biome (AFB) creates an ideal environment for the proliferation of vector mosquitoes, such as Haemagogus and Sabethes species, which transmit Yellow Fever virus (YFV) to both human non-human primates (NHP) (particularly Alouatta sp. Callithrix sp.). From 2016 2020, 748 fatal cases YF in humans 1,763 NHPs were reported this biome, following several years free from disease. This underscores imminent risk posed by YFV. In study, we examined spatiotemporal distribution...
Abstract Ensuring the demographic and genetic viability of small populations threatened primates requires a range management approaches. Here we describe novel mixed in situ ex project that was developed to restore population Critically Endangered northern muriqui Brachyteles hypoxanthus . This isolated population, located Ibitipoca, Lima Duarte, Minas Gerais, Brazil, had declined two adult males would have gone extinct without intervention. A first attempt at 2017 involved translocation...
Abstract Background Although malaria transmission was eradicated from southeast Brazil, a significant increase in the number of Plasmodium vivax-like autochthonous human cases has been reported remote areas Atlantic Forest last decades Rio de Janeiro (RJ) state, including an outbreak 2015-2016. The singular clinical and epidemiological aspects several combined with molecular genetic data revealed that they were due to non-human primate (NHP) parasite P. simium. full understanding...
