Spatial distribution of triatomine bugs in a Chagas disease endemic region in Brazil

CONCLUSIONS: These data contribute to a better understanding of the distribution of T. cruzi infection in the Northeastern region of Brazil. Preventive measures based on vector control should be implemented in the study ar ea in order to reduce the burden this neglected tropical disease.

Abstract Trypanosoma cruzi is a zoonotic protozoan parasite vectored by triatomine insects that are endemic to the Americas, including the southern United States. Surveillance of domestic dogs for T. cruzi exposure allows for determination of geographic regions of transmission that are relevant for human and animal health. The U.S. Department of Homeland Security (DHS) working dogs provide critical security and detection services across the country, and many train or work in the southern United States, where they are at risk for T. cruzi exposure. We sampled blood from 1,610 working dogs (predominantly, Belgian Ma...

Abstract National parks attract millions of visitors each year. Park visitors, employees, and pets are at risk of infection with various zoonotic pathogens, including Trypanosoma cruzi, causative agent of Chagas disease. Big Bend National Park is located along the Texas-Mexico border in a region with endemic triatomine insects- vectors of T. cruzi- yet the degree to which the parasite is transmitted in this region is unknown. We collected triatomines for T. cruzi detection and discrete typing unit (DTU) determination, and conducted blood meal analyses to determine recent hosts. As an index of domestic/peridomestic...

PREVALENCE OF AMERICAN TRYPANOSOMIASIS AND LEISHMANIASES IN DOMESTIC DOGS IN A RURAL AREA OF THE MUNICIPALITY OF SÃO JOÃO DO PIAUÍ, PIAUÍ STATE, BRAZIL. Rev Inst Med Trop Sao Paulo. 2016 Nov 03;58:79 Authors: Perez TD, Figueiredo FB, Junior AA, Silva VL, Madeira MF, Brazil RP, Coura JR Abstract Chagas disease and the leishmaniases are endemic zoonoses of great importance to public health in the state of Piauí, Brazil. The domestic dog (Canis familiaris) is a major reservoir, host of Trypanosoma cruzi and Leishmania spp. in both urban and rural areas, playing an impor...

Discussion People often don’t think that developed countries have parasitic diseases but this is not true. The major parasitic infections endemic in the United States can be thought of as: Intestinal parasitic infections Seen throughout the US but especially in the northern states during the summer Often occur through recreational water use Cryptosprodiosis, Dientamoebiasis and Giardiasis are the most common. Neglected tropical diseases Seen especially in the southern states (especially Texas) and are linked to extreme poverty Chagas disease, Cutaneous Leishmaniasis, Toxocariasis, and Toxoplasmosis are the most co...

Conclusions/Significance Triatoma protracta populations in California are frequently infected with T. cruzi. Our data extend the northern limits of the range of TcI and identify a novel genetic exchange event between TcI and TcIV. High similarity between sequences from California and specific Latin American strains indicates US strains may be equally capable of causing human disease. Additional genetic characterization of Californian and other US T. cruzi strains is recommended.

Conclusions: This study reveals the role of peridomestic T. maculata and dogs in T. cruzi persistence in this region and presents evidence that D. marsupialis are a reservoir mediating peridomestic-zoonotic cycles. This picture reflects the complexity of the transmission dynamics of T. cruzi in an endemic area with non-domiciliated vectors where active human infection exists. There is an ongoing need to control peridomestic T. maculata populations and to implement continuous reservoir surveillance strategies with community participation.
