Item type: Item , Can wild foci in Bolivia jeopardize Chagas disease control efforts?(Elsevier BV, 2005) François Noireau; Mirko Rojas Cortez; Fernando A. Monteiro; Ana María Jansen; Faustino TorricoItem type: Item , Infestation of peridomestic<i>Attalea phalerata</i>palms by<i>Rhodnius stali</i>, a vector of<i>Trypanosoma cruzi</i>in the Alto Beni, Bolivia(Wiley, 2010) Silvia A. Justi; François Noireau; Mirko Rojas Cortez; Fernando A. MonteiroAttalea phalerata palms represent an important sylvatic ecotope occupied by R. stali in the Alto Beni region of Bolivia, where there are signs of T. cruzi transmission to humans, despite the preliminary indication of low level of natural infection of the vectors.Item type: Item , Mitochondrial DNA variation of Triatoma infestans populations and its implication on the specific status of T. melanosoma(Instituto Oswaldo Cruz, Ministério da Saúde, 1999) Fernando A. Monteiro; Ruben Pérez; Francisco Panzera; Jean-Pierre Dujardin; Cléber Galvão; Deyse Rocha; François Noireau; Chris Schofield; Charles B. BeardDNA sequence comparison of 412 base-pairs fragments of the mitochondrial cytochrome B gene was used to infer the genetic structure of nine geographical Triatoma infestans populations and their phylogenetic relationship with T. melanosoma and T. brasiliensis. T. infestans and T. melanosoma were compared by morphometry, allozyme and cytogenetic analyses, as well as subjected to reciprocal crosses, in order to clarify the taxonomic status of the latter. No differences were found to distinguish the two species and the crosses between them yielded progeny. T. infestans populations presented four haplotypes that could be separated in two clusters: one formed by the samples from Bolivia (Andes and Chaco) and the other formed by samples from Argentina and Brazil. Silvatic and domestic T. infestans populations from Bolivia (Andes) were genetically identical.Item type: Item , New insights on the spread of Triatoma infestans from Bolivia—Implications for Chagas disease emergence in the Southern Cone(Elsevier BV, 2010) Mirko Rojas Cortez; Fernando A. Monteiro; François Noireau
