| genetic structure of triatoma venosa (hemiptera: reduviidae): molecular and morphometric evidence. | triatoma venosa presents a restricted geographical distribution in america and is considered as a secondary vector of chagas disease in colombia and ecuador. a total of 120 adult insects were collected in domestic and peridomestic habitats in an endemic area of the department of boyacá, colombia, in order to determine their genetic structure through morphometric and molecular techniques. the head and wings of each specimen were used for the analyses of size, shape, and sexual dimorphism. a signi ... | 2006 | 16699708 |
| [updated geographical distribution and ecoepidemiology of the triatomine fauna (reduviidae: triatominae) in colombia]. | information concerning triatomine records from provinces and municipalities was accumulated-including data indicating natural infections with trypanosomatides-that has been previously published or reported by colombian provincial health services and research institutes. altitude appeared to be the main factor responsible for the distribution of the insects. illustrations summarize the information provided by the above records. a triatomine fauna classification is presented that corresponds to th ... | 2007 | 18154255 |
| validation of a poisson-distributed limiting dilution assay (lda) for a rapid and accurate resolution of multiclonal infections in natural trypanosoma cruzi populations. | trypanosoma cruzi is the causative agent of american trypanosomiasis, a complex zoonotic disease that affects more than 10million people in the americas. strains of this parasite possess a significant amount of genetic variability and hence can be divided into at least six discrete typing units (dtus). the life cycle of this protist suggests that multiclonal infections may emerge due to the likelihood of contact of triatomine insects with more than 100 mammal species. to date, there have been a ... | 2013 | 23159798 |
