the triatomines of northern peru, with emphasis on the ecology and infection by trypanosomes of rhodnius ecuadoriensis (triatominae).	information on the distribution and synanthropic behaviour of triatomines is essential for chagas disease vector control. this work summarises such information from northern peru, and presents new data on rhodnius ecuadoriensis - an important local vector infesting 10-35% of dwellings in some zones. three species are strongly synanthropic and may be suitable targets for chemical control of domestic/peridomestic bug populations. panstrongylus herreri, the main domestic vector in the area, is prob ...	2002	12016438
domestic rhodnius ecuadoriensis (hemiptera, reduviidae) infestation in northern peru: a comparative trial of detection methods during a six-month follow-up.	two passive methods in the assessment of intradomiciliary infestation by rhodnius ecuadoriensis were tested: (i) the gomes nu ez sensor box (gn), (ii) sheets of white typing paper and (iii) one active timed manual method. the study was carried out in the alto chicama river valley, province of gran chim , department of la libertad. the study design consisted of an initial searching of triatomines inside of the domestic environment by the manual capture active procedure (man/hour) covering all the ...	2003	12754573
molecular characterisation of trypanosoma rangeli strains isolated from rhodnius ecuadoriensis in peru, r. colombiensis in colombia and r. pallescens in panama, supports a co-evolutionary association between parasites and vectors.	we present data on the molecular characterisation of strains of trypanosoma rangeli isolated from naturally infected rhodnius ecuadoriensis in peru, from rhodnius colombiensis, rhodnius pallescens and rhodnius prolixus in colombia, and from rhodnius pallescens in panama. strain characterisation involved a duplex pcr with s35/s36/kp1l primers. mini-exon gene analysis was also carried out using trint-1/trint-2 oligonucleotides. kdna and mini-exon amplification indicated dimorphism within both dna ...	2005	15639744
trypanosoma rangeli genotypes association with rhodnius prolixus and r. pallescens allopatric distribution in central america.	previous kdna polymorphism-based reports have revealed the existence of two trypanosoma rangeli genotypes (kp1+ and kp1-): sl and ssu rrna gene polymorphism-based studies have revealed that five genotypes (a-e) are distributed throughout different latin-american countries. some evidence has shown that the genotypes' biogeographical distribution is associated with sympatric rhodnius species. 12 t. rangeli isolates from humans and reservoirs from el salvador, guatemala, honduras, costa rica and pa ...	2009	19778637
sequence analysis of the spliced-leader intergenic region (sl-ir) and random amplified polymorphic dna (rapd) of trypanosoma rangeli strains isolated from rhodnius ecuadoriensis, r. colombiensis, r. pallescens and r. prolixus suggests a degree of co-evolution between parasites and vectors.	spliced leader intergenic region (sl-ir) sequences from 23 trypanosoma rangeli strains isolated from the salivary glands of rhodnius colombiensis, r. ecuadoriensis, r. pallescens and r. prolixus and two human strains revealed the existence of 4 genotypes with ca, gt, ta, att and gtat microsatellite repeats and the presence of insertions/deletions (indel) and single nucleotide polymorphism (snp) characterizing each genotype. the strains isolated from the same vector species or the same rhodnius e ...	2011	21718675
prevalence, genetic characterization, and 18s small subunit ribosomal rna diversity of trypanosoma rangeli in triatomine and mammal hosts in endemic areas for chagas disease in ecuador.	trypanosoma rangeli is a nonpathogenic parasite for humans; however, its medical importance relies in its similarity and overlapping distribution with trypanosoma cruzi, causal agent of chagas disease in the americas. the genetic diversity of t. rangeli and its association with host species (triatomines and mammals) has been identified along central and the south america; however, it has not included data of isolates from ecuador. this study reports infection with t. rangeli in 18 genera of mamm ...	2015	26645579
molecular epidemiology of trypanosoma cruzi and triatoma dimidiata in costal ecuador.	chagas disease is a neglected tropical disease caused by the protozoan parasite trypanosoma cruzi. in ecuador, triatoma dimidiata and rhodnius ecuadoriensis are the main vector species, responsible for over half of the cases of t. cruzi infection in the country. t. dimidiata is believed to have been introduced in ecuador during colonial times, and its elimination from the country is thus believed to be feasible. we investigated here the molecular ecology of t. dimidiata and t. cruzi in costal ec ...	2016	27079265
