Survey of Plasmodium in the golden-headed lion tamarin (Leontopithecus chrysomelas) living in urban Atlantic forest in Rio de Janeiro, Brazil

Abstract Background Communicating the presence of potential zoonotic pathogens such as Plasmodium spp. in wild animals is important for developing both animal and human health policies. Methods The translocation of an exotic and invasive population of Leontopithecus chrysomelas (golden-headed lion tamarins) required the screening of these animals for specific pathogens. This studies objective was to investigate Plasmodium spp. infection in the L. chrysomelas, both to know its prevalence in these animals in the local area and to minimize the risk of pathogens being translocated to the destination site. To investigate Plasmodium spp. infection, blood samples from 268 animals were assessed for the presence of Plasmodium spp. by genus-specific PCR and stained thick and thin blood smears were examined by light microscopy. Data of human malaria infection in the studied region was also assembled from SINAN (Diseases Information System Notification—Ministry of Health of Brazil). Results Results from the PCR and microscopy were all negative and suggested that no L. chrysomelas was infected with Plasmodium spp. Analysis of SINAN data showed that malaria transmission is present among the human population in the studied region. Conclusions This study is the first to provide information on Plasmodium spp. infection in L. chrysomelas. Plasmodium spp. infection of this species is rare or absent though malaria parasites circulate in the region. In addition, there is minimal risk of translocating Plasmodium spp. infected animals to the destination site

Molecular Investigation Confirms Myotis Genus Bats as Common Hosts of Polychromophilus in Brazil

Plasmodium spp. and some other blood parasites belonging to the order Haemosporida are the focus of many epidemiological studies worldwide. However, haemosporidian parasites from wild animals are largely neglected in scientific research. For example, Polychromophilus parasites, which are exclusive to bats, are described in Europe, Asia, Africa, and Oceania, but little is known about their presence and genetic diversity in the New World. In this study, 224 samples of bats from remaining fragments of the Atlantic Forest and Pantanal biomes, as well as urbanized areas in southern and southeastern Brazil, were analyzed for the presence of haemosporidian parasites by PCR of the mitochondrial gene that encodes cytochrome b (cytb). The PCR fragments of the positive samples were sequenced and analyzed by the Bayesian inference method to reconstruct the phylogenetic relationships between Polychromophilus parasites from bats in Brazil and other countries. Sequences from Brazilian lineages of Polychromophilus were recovered in a clade with sequences from Polychromophilus murinus and close to the one Polychromophilus sequence obtained in Panama, the only available sequence for the American continent. This clade was restricted to bats of the family Vespertilionidae and distinct from Polychromophilus melanipherus, a parasite species mainly found in bats of the family Miniopteridae. The detection of Polychromophilus and the genetic proximity to P. murinus were further confirmed with the amplification of two other genes (clpc and asl). We also found a Haemosporida parasite sequence in a sample of Noctilio albiventris collected in the Pantanal biome, which presents phylogenetic proximity with avian Haemoproteus sequences. Morphological and molecular studies are still needed to conclude and describe the Polychromophilus species in Brazilian Myotis bats in more detail and to confirm Haemoproteus parasites in bats. Nevertheless, these molecular results in Brazilian bats confirm the importance of studying these neglected genera.Fil: da Silva Mathias, Bruno.

From colorectal cancer pattern to the characterization of individuals at risk: Picture for genetic research in Latin America

Colorectal cancer (CRC) is one of the most common cancers in Latin America and the Caribbean, with the highest rates reported for Uruguay, Brazil and Argentina. We provide a global snapshot of the CRC patterns, how screening is performed, and compared/contrasted to the genetic profile of Lynch syndrome (LS) in the region. From the literature, we find that only nine (20%) of the Latin America and the Caribbean countries have developed guidelines for early detection of CRC, and also with a low adherence. We describe a genetic profile of LS, including a total of 2,685 suspected families, where confirmed LS ranged from 8% in Uruguay and Argentina to 60% in Peru. Among confirmed LS, path_MLH1 variants were most commonly identified in Peru (82%), Mexico (80%), Chile (60%), and path_MSH2/EPCAM variants were most frequently identified in Colombia (80%) and Argentina (47%). Path_MSH6 and path_PMS2 variants were less common, but they showed important presence in Brazil (15%) and Chile (10%), respectively. Important differences exist at identifying LS families in Latin American countries, where the spectrum of path_MLH1 and path_MSH2 variants are those most frequently identified. Our findings have an impact on the evaluation of the patients and their relatives at risk for LS, derived from the gene affected. Although the awareness of hereditary cancer and genetic testing has improved in the last decade, it is remains deficient, with 39%–80% of the families not being identified for LS among those who actually met both the clinical criteria for LS and showed MMR deficiency.Fil: Vaccaro, Carlos Alberto.

Survey of Leishmania spp. and Plasmodium spp. in neotropical primates form Atlantic Forest and Amazon Regions impacted by humans activities: in situ and ex situ study

Este trabalho investigou a ocorrência de infecções causadas por Plasmodium spp. e Leishmania spp. em primatas neotropicais mantidos em cativeiro e de vida livre, oriundos de regiões impactadas pelo homem nos biomas Mata Atlântica e Amazônia. Os agentes parasitários investigados são responsáveis por processos zoonóticos que acometem humanos, animais domésticos e selvagens, com significativas perdas ambientais e econômicas. Amostras biológicas foram colhidas e submetidas para análise parasitária por testes sorológicos e moleculares. Com relação aos plasmódios, os resultados alcançados sugerem a transmissão de Plasmodium spp. entre os primatas de cativeiro e de vida livre. No estado de São Paulo, nossos dados apontam para a circulação de P. malariae e P. simium, sendo este último encontrado em Callicebus nigrifrons. Na Amazônia, nossos dados indicam a circulação de P. brasilianum. Com relação às leishmanias, demonstramos que circula entre os primatas de cativeiro do estado de São Paulo a L. (L.) chagasi, as L. (L.) amazonenses e as leishmanias do complexo Viannia. Na região amazônica, 5,2% (1/19) foram positivos no PCR de sangue para L. (L.) chagasi. Os resultados deste trabalho podem subsidiar abordagens sanitárias públicas e veterinárias com relação aos primatas neotropicais existentes no estado de São Paulo e nas regiões Amazônicas.This study investigated the occurrence of infections caused by Plasmodium spp. and Leishmania spp. in neotropical primates. Specimens were obtained both in captivity and in the wild in regions impacted by human activities in the Atlantic Forest and Amazon, Brazil. The pathogens investigated are responsible for significant zoonotic processes that affect humans, domestic and wild animals, with significant economic and environmental losses. The samples were collected and submitted for analysis by serological and molecular tests. The results suggest the transmission of Plasmodium spp. in primates from captive to those in the wild. In São Paulo state our data point for the presence of P. malariae and P. simium, this latter being found in Callicebus nigrifrons. In the Amazon, our data indicate the presence of P. brasilianum. Leishmania (L.) chagasi, L. (L.) amazonensis and the Leishmania Viannia complex circulates among the captive primates in São Paulo state. In the Amazon, 5.2% (1/19) of the primates sampled were detected by PCR as positive for L. (L.) chagasi. The results of this work may improve animal and public health approaches in relation to the neotropical primates in the regions studied

Curitiba, PR , Brasil.Fundação Oswaldo Cruz. Programa Institucional Biodiversidade e Saúde. Rio de Janeiro, RJ, Brasil.Zika virus (ZIKV) was first isolated in 1947 in primates in Uganda, West Africa. The virus remained confined to the equatorial regions of Africa and Asia, cycling between infecting monkeys, arboreal mosquitoes, and occasionally humans. The ZIKV Asiatic strain was probably introduced into Brazil in or around late 2013. Presently, ZIKV is in contact with the rich biodiversity in all Brazilian biomes, bordering on other Latin American countries. Infections in Brazilian primates have been reported recently, but the overall impact of this virus on wildlife in the Americas is still unknown. The current epidemic in the Americas requires knowledge on the role of mammals, especially nonhuman primates (NHPs), in ZIKV transmission to humans. The article discusses the available data on ZIKV in host animals and issues of biodiversity, rapid environmental change, and impact on human health in megadiverse Latin American countries. The authors reviewed scientific articles and recent news stories on ZIKV in animals, showing that 47 animal species from three orders (mammals, reptiles, and birds) have been investigated for the potential to establish a sylvatic cycle. The review aims to contribute to epidemiological studies and the knowledge on the natural history of ZIKV. The article concludes with questions that require urgent attention in epidemiological studies involving wildlife in order to understand their role as ZIKV hosts and to effectively control the epidemic
