2. Spatial distribution of triatomine bugs in a Chagas disease endemic region in Brazil
Abstract INTRODUCTION: Trypanosoma cruzi is the etiological agent of Chagas disease (CD), a zoonotic infection transmitted by triatomine bug vectors to human beings. Although the story of this parasitic infection was born in Brazil and here this has made major step forward information, the same cannot be said about the actual distribution of the triatomine

3. Anti-complement activity in salivary glands and midgut of Chagas disease vector, Panstrongylus megistus (Hemiptera, Triatominae)
ABSTRACT The triatomine insect Panstrongylus megistus , one of the most important Chagas disease vectors in Brazil, presents salivary molecules pharmacologically active to counteract homeostatic responses from the host, including inhibitors of the human complement system, a major effector of immune responses. The aim of the present study was to investigate t

4. Occurrences of triatomines (Hemiptera: Reduviidae) and first reports of Panstrongylus geniculatus in urban environments in the city of Sao Paulo, Brazil
ABSTRACT This note reports on occurrences of triatomine species in the city of Sao Paulo, Brazil, registered between 1988 and 2017. Records of triatomines captured in Sao Paulo are based on specimens received spontaneously from Health Surveillance Centers, Health Centers and Zoonosis Control Centers in the city as well as from citizens. Species were identifi

5. Insect vectors of Chagas disease (Trypanosoma cruzi) in Northeastern Brazil
Abstract INTRODUCTION: Chagas disease remains a public health problem in the rural and urban areas of 19 countries in the Americas. METHODS: The aim of the present study was to investigate the Trypanosoma cruzi infection rate of triatomines collected from both intra- and peridomiciliary areas in eleven municipalities of Southeastern Ceará, Brazil, from

6. Synanthropic triatomines as potential vectors of Trypanosoma cruzi in Central Brazil
Abstract INTRODUCTION: Chagas disease surveillance requires current knowledge on synanthropic triatomines. We analyzed the occurrence and Trypanosoma cruzi infection rates of triatomine bugs in central Brazil, during 2012-2014. METHODS: Triatomines were collected inside or around houses, and T. cruzi infection was determined by optical microscopy and con

7. Atividade da enzima ATPase dependente de MG 2+ em glândulas salivares de triatomíneos (Heteroptera, Triatominae)
RESUMO A atividade da enzima ATPase dependente de Mg2+ foi detectada nas três glândulas salivares de triatomíneos adultos, machos e fêmeas, de Triatoma infestans (Klug, 1834) e Panstrongylus megistus (Burmeister, 1835) (Heteroptera, Triatominae). Observou-se um predomínio de células binucleadas em D1 e D2, e mononucleadas em D3, com núcleos volumosos

8. Occurrence and distribution of triatomines (Hemiptera: Reduviidae) in municipalities of the Northeastern region of Minas Gerais State, Brazil
Abstract: INTRODUCTION: Triatomines are targeted for the control of Chagas disease in endemic areas of Brazil. METHODS: Data regarding triatomines captured during 2001-2008 in 34 municipalities in the Northeast of Minas Gerais were analyzed. RESULTS: In total, 11,187 triatomines from eight species were captured, mostly in henhouses and bedrooms. Trypan

9. Trypanosoma cruzi isolated from a triatomine found in one of the biggest metropolitan areas of Latin America
Abstract: INTRODUCTION: To characterize Trypanosoma cruzi (TcI) isolated from a Panstrongylus megistus specimen found in one of the biggest metropolitan areas of Latin America, the relationship between the TcI group of T. cruzi and the transmission cycle in the urban environment was studied. METHODS: The T. cruzi strain, Pm, was isolated in a culture med

10. Spatial distribution of triatomines in domiciles of an urban area of the Brazilian Southeast Region
Reports of triatomine infestation in urban areas have increased. We analysed the spatial distribution of infestation by triatomines in the urban area of Diamantina, in the state of Minas Gerais, Brazil. Triatomines were obtained by community-based entomological surveillance. Spatial patterns of infestation were analysed by Ripley’s K function and Kernel de
