Metalloproteases in Trypanosoma rangeli-infected Rhodnius prolixus [PDF]

Memórias do Instituto Oswaldo Cruz, 1999
Protease activities in the haemolymph and fat body in a bloodsucking insect, Rhodnius prolixus, infected with Trypanosoma rangeli, were investigated. After SDS-polyacrylamide gel electrophoresis containing gelatin as substrate, analysis of zymograms performed on samples of different tissues of controls and insects inoculated or orally infected with ...

Aggregation Behaviour and Interspecific Responses in Rhodnius prolixus Stål

Memorias do Instituto Oswaldo Cruz, 2002
The response to intra- and interspecific faecal assembling signals was tested in Rhodnius prolixus. Papers impregnated with excrement of R. prolixus induced the aggregation of larvae of this species, but also of those of Triatoma infestans.

Attraction of Rhodnius prolixus males to a synthetic female-pheromone blend

Parasites & Vectors, 2018
Background The triatomine bug Rhodnius prolixus Stål, 1859 (Heteroptera: Reduviidae) is the primary vector of Chagas disease in Colombia and Venezuela. An important step in controlling Chagas disease is monitoring the growth and spread of bug populations

New Cell Lines Derived from Laboratory Colony Triatoma infestans and Rhodnius prolixus, Vectors of Trypanosoma cruzi, Do Not Harbour Triatoma Virus

Insects, 2022
Triatomine bugs of the genera Triatoma and Rhodnius are vectors of Chagas disease, a neglected tropical disease of humans in South America caused by Trypanosoma cruzi. Triatoma virus (TrV), a natural pathogen of Triatoma infestans, has been proposed as a

The interplay between temperature, Trypanosoma cruzi parasite load, and nutrition: Their effects on the development and life-cycle of the Chagas disease vector Rhodnius prolixus

PLoS Neglected Tropical Diseases
Chagas disease, caused by the protozoan parasite Trypanosoma cruzi transmitted by blood-sucking insects of the subfamily Triatominae, is a major neglected tropical disease affecting 6 to 7 million of people worldwide.

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

Revista da Sociedade Brasileira de Medicina Tropical
: 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 ...

Verificação de flagelados semelhantes ao Trypanosoma rangeli Tejera, em Rhodnius prolixus alimentados em caso de doença de Chagas na Venezuela: considerações sobre a natureza deste protozoário

Memorias do Instituto Oswaldo Cruz, 1943
1) - Por inoculação do sangue de um caso agúdo de moléstia de Chagas de Zaraza, Guárico, Venezuela, em cobaia (12-11-1940), obteve-se um Schizotrypanum com caractéres morfológicos distintos dos das amostras humanas comuns do Schizotrypanum cruzi; seu ...

Rhodnius prolixus uses the peptidoglycan recognition receptor rpPGRP-LC/LA to detect Gram-negative bacteria and activate the IMD pathway

Current Research in Insect Science, 2020
Highlights • The IMD pathway pattern recognition receptors are conserved in Triatomines.• Rhodnius prolixus PGRPs lack key residues required for amidase activity.• rpPGRP-LC/LA isoforms contain cRHIMs and are highly expressed in the fat body.• Silencing ...
