Current spread of Triatoma infestans at the expense of Triatoma sordida in Bolivia
Noireau, François; Brenière, Frédérique; Cardozo, Lucyla; Bosseno, Marie France; Vargas, Fernando; Peredo, Carlos; Medinacelli, Marlon (Mem. Inst. Oswaldo Cruz, 1996)Triatoma infestans is the most widespread synanthropic species of Triatominae and the most important vector of Chagas disease in South America. The progressive geographical expansion of this species from its silvatic focus ... -
Genetic variability and microdistribution of Triatoma infestans genotypes and Trypanosoma cruzi clones in Arequipa región (Peru)
Brenière, Simone F; López, Jenny; Vargas, Fernando; Barnabé, Christian (Mem. Inst. Oswaldo Cruz, 1997)The genetic variability of Triatoma infestans and Trypanosoma cruzi populations was studied by isoenzyme analysis in two distinct areas of Arequipa province (Peru); one, Santa Rita de Siguas, being an endemic area for ... -
Sylvatic triatomines (Hemiptera: Reduviidae) in Bolivia : trends toward domesticity and possibleinfection with Trypanosoma cruzi (Kinetoplastida: Trypanosomatidae)
Noireau, François; Bosseno, Marie-France; Carrasco, Roxana; Telleria, Jenny; Vargas, Fernando; Camacho, Clara; Yaksic, Nina; Brenière, Simone Frederique (Journal of Medical Entomology, 1995)ABSTRACT The risk of domestic transmission of Trypanosoma cruzi (Chagas) by sylvatic triatomines was assessed in an isolated area of the subandean region of Bolivia. None of the 390 residents examined had serological ... -
Trypanosoma cruzi : study of the distribution of two widespread clonal genetypes in Bolivian Triatoma infestans vectors shows a high frequency of mixed infestions
Bosseno, Marie-France; Telleria, Jenny; Vargas, Fernando; Yaksic, Nina; Noireau, François; Morin, Annie; Brenière, Simone Frédérique (Experimental Parasitology, 1996)Abstract. The detection of two widespread Trypanosoma cruzi clonal genotypes (20 and 39) in feces of Bolivian specimens of the vector Triatoma infestans was performed by a combination of polymerase chain reaction and ...
