Biomédica (Bogotá); 39 (2), 2019
Abstract Introduction: From 2011 to 2016, 24 cases of Chagas disease were reported in Córdoba according to the national public health surveillance system (Sistema Nacional de Vigilancia en Salud Pública, Sivigila), but the information regarding Trypanosoma cruzi circulating strains and infection rates...

Occurrence of triatomines in an urban residential complex in the municipality of Rio Branco, Acre, South-Western Amazon

Abstract INTRODUCTION: This study describes the occurrence of triatomines, and their positivity for trypanosomatids, in a residential complex in Rio Branco, Acre, Brazil. METHODS: Triatomines were collected through direct capture in a home environment. Positivity analysis for trypanosomatids was perf...

Survey of trypanosoma (kinetoplastida: trypanosomatidae) infection in Monte Negro Municipality, State of Rondônia, western amazon, with first record of T. evansi in the state

Abstract INTRODUCTION: Trypanosomes can infect humans and animals. This is the first record of the occurrence of Trypanosoma evansi in Rondônia. METHODS: Blood samples were collected from 7 dogs and 22 humans. Furthermore, triatomines and tabanids were collected. RESULTS: It was observed that 42.8%...

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 elev...

Rhodnius stali: new vector infected by Trypanosoma rangeli (Kinetoplastida, Trypanosomatidae)

Abstract INTRODUCTION Rhodnius stali infection by Trypanosoma rangeli is reported in this study for the first time. METHODS The triatomines were collected from the campus of the Federal University of Acre in Rio Branco, Acre, Brazil. The identification of T. rangeli was confirmed by multiplex polymera...

Behavioral fever response in Rhodnius prolixus (Reduviidae: Triatominae) to intracoelomic inoculation of Trypanosoma cruzi

Abstract: INTRODUCTION: Behavioral fever is a response to infections with microorganisms observed in some poikilothermic animals. Rhodnius prolixus is involved in the transmission of two parasites: Trypanosoma cruzi (pathogenic for humans and transmitted in feces) and Trypanosoma rangeli (non-pathogeni...

Characteristics of Triatomine infestation and natural Trypanosoma cruzi infection in the State of Rio Grande do Norte, Brazil

Abstract: INTRODUCTION Natural and artificial ecotope infestation by the kissing bug triatomines and their colonization and infection by Trypanosoma cruzi , the Chagas disease agent, were evaluated in nine municipalities of the State of Rio Grande do Norte, Brazil. METHODS Following identification, triat...

Natural infection of triatomines (Hemiptera: Reduviidae) by trypanosomatids in two different environments in the municipality of Ouro Preto do Oeste, State of Rondônia, Brazil

INTRODUCTION: This study analyzed the occurrence and the contamination of triatomines by trypanosomatids in Orbignya speciosa (babassu) specimens in the State of Rondônia, Brazil, in two different environments (pasture and woods). METHODS: Capture of triatomines on babassus and microscopic search for tr...

Studies in search of a suitable experimental insect model for xenodiagnosis of hosts with Chagas' disease: 4. The reflection of parasite stock in the responsiveness of different vector species to chronic infection with different Trypanosoma cruzi..

Rev. saúde pública; 24 (3), 1990
Estudos anteriores (1982, 1987) enfatizaram a superioridade das espécies vetoras silvestres às domiciliadas, como agentes do xenodiagnòstico nas infecçöes agudas e crônicas pelo isolado Y do T.cruzi. Os dados atuais estabeleceram a generalidade deste fenômeno. Por exemplo, a proporçäo de positiv...
