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 ...

Rhodnius prolixus intoxicated

Journal of Insect Physiology, 2017
Rhodnius prolixus (Hemiptera: Reduviidae) is a hematophagous insect native from South America. By the end of the 20th century, it was one of the main vectors of Chagas disease in Venezuela, Colombia, several Central American countries and southern Mexico. The aim of the present article is to review the literature regarding R.

Elimination of Rhodnius prolixus in Central America [PDF]

Parasites & Vectors, 2012
Rhodnius prolixus is one of the main vectors of Trypanosoma cruzi, causative agent of Chagas disease. In Central America, it was first discovered in 1915 in El Salvador, from where it spread northwest to Guatemala and Mexico, and southeast to Nicaragua and Costa Rica, arriving also in Honduras in the late 1950s.

Oviposition in the blood-sucking insect Rhodnius prolixus is modulated by host odors [PDF]

, 2015
Background: Triatomine bugs are blood-sucking insects, vectors of Chagas disease. Despite their importance, their oviposition behavior has received relatively little attention. Some triatomines including Rhodnius prolixus stick their eggs to a substrate.

Rhodnius prolixus Malpighian tubules and control of diuresis by neurohormones

Anais da Academia Brasileira de Ciências, 2007
Rhodnius prolixus Malpighian tubules (MTs) are a good model for fluid and ion secretion studies in view of the dramatic postprandial diuresis, which follows its massive blood meals. Ingestion of a blood meal equals to 10-12 times their initial body mass,
