“…Didelphis albiventris is a known reservoir of T. cruzi (Herrera et al, 2005), playing an important role in the protozoan transmission cycle, since it transits between wild and anthropic environments, being considered as a synanthropic species (Nantes et al, 2019). Previous studies have reported the T. cruzi infection rate in the species D. albiventris ranging from 9% to 100% depending on the region sampled (Drozino et al, 2019;Herrera et al, 2005;Jansen et al, 2015Jansen et al, , 2018Nantes et al, 2019). Natural infection by T. cruzi in K. rupestris protozoan (Bezerra et al, 2014;Jansen et al, 2018).…”

The present study, carried out in the municipality of Gentio do Ouro, Bahia, Brazil aimed to evaluate which wild mammals may be involved in the transmission of T. cruzi and which are the blood sources for triatomines collected in the study area. PCR analysis of 31 wild mammals captured revealed T. cruzi infection in 6.4% (2/31): one specimen of the opossum Didelphis albiventris (1/3) and one of the rodent Kerodon rupestris (1/5); despite being more frequent in the area, no specimen of the rodent Thrichomys sp. (0/23) was infected. A total of 169 triatomines were captured. The conclusive detection of food sources was possible only for Triatoma sherlocki Papa et al., 2002 (n = 56), with evidence for: K. rupestris (35.7%), Gallus (17.9%), D. albiventris (14.3%), Homo sapiens (14.3%), Tropidurus hispidus (7.1%), Leopardus geoffroyi (5.3%), Conepatus semistriatus (1.8%), Thrichomys inermis (1.8%) and Rattus norvegicus (1.8%). Triatomines of the species T. sherlocki showed food eclecticism, including feeding on humans, with some of them being captured at dwellings. These facts make this triatomine a potential link for the transmission of T. cruzi between wild and anthropic environments, highlighting a latent risk of the reemergence of Chagas disease outbreaks.

“…The most common way of transmission of Trypanosoma spp. is through an invertebrate vector (Zabalgoitia et al 2003, Sathler-Avelar et al 2017, Jansen et al 2018, Drozino et al 2019. Capuchin monkeys and marmosets have a habit of sleeping in tangles of vines, bromeliads, and in the base of palm leaves, places where the vector may be present.…”

Molecular detection and phylogenetic analysis of Trypanosoma spp. in Neotropical primates from Rio de Janeiro State, Brazil

et al. 2022

Trypanosoma spp. infection is a problem in many tropical countries, infecting several animal species, including humans. The aim of the present study was to identify the Trypanosoma species in Neotropical primates from Rio de Janeiro state and compare the results with other reports both phylogenetically and geographically. Molecular detection was based on the 18 SSU gene. The sequences obtained in the PCR were sequenced and compared with others previously deposited in GenBank. These sequences were used to perform phylogenetic analysis and make a distribution map of primate species infected by Trypanosoma species in Brazil. Among 34 monkeys, five capuchin monkeys (Sapajus spp.) and one marmoset (Callithrix spp.) showed Trypanosoma spp. sequences in the same clade of Trypanosoma minasense and three capuchin monkeys’ sequences were in the same clade of Trypanosoma cruzi. The Atlantic Forest and the Brazilian Amazon are the regions with the highest frequency of studies about Trypanosoma spp. and variety of Neotropical primate hosts. These are areas that deserve attention regarding the conservation of biodiversity, but it also makes evident the lack of studies with Neotropical primates in other regions of the country, as well as multidisciplinary studies to better understand the host pathogen relationships.
