| epidemiology of trypanosoma cruzi in the oriental plains of colombia. | epidemiologic studies to define the domiciliary and extradomiciliary transmission cycles of trypanosoma cruzi and trypanosoma rangeli in the oriental plains of colombia were conducted in the gallery forests near carimagua and el porvenir. one-hundred and seven palm trees belonging to nine genera were examined; triatomines were found in only three palm species, the leaves of which are locally used for roof thatching: 2/29 maximiliana elegans, 1/7 mauritia flexuosa and 7/7 scheelea sp. bugs were a ... | 1984 | 6439062 |
| the ecotopes and evolution of triatomine bugs (triatominae) and their associated trypanosomes. | triatomine bug species such as microtriatoma trinidadensis, eratyrus mucronatus, belminus herreri, panstrongylus lignarius, and triatoma tibiamaculata are exquisitely adapted to specialist niches. this suggests a long evolutionary history, as well as the recent dramatic spread a few eclectic, domiciliated triatomine species. virtually all species of the genus rhodnius are primarily associated with palms. the genus panstrongylus is predominantly associated with burrows and tree cavities and the g ... | 2000 | 10904415 |
| attraction of chagas disease vectors (triatominae) to artificial light sources in the canopy of primary amazon rainforest. | adult triatomines occasionally fly into artificially lit premises in amazonia. this can result in trypanosoma cruzi transmission to humans either by direct contact or via foodstuff contamination, but the frequency of such behaviour has not been quantified. to address this issue, a light-trap was set 45 m above ground in primary rainforest near manaus, state of amazonas, brazil and operated monthly for three consecutive nights over the course of one year (432 trap-hours). the most commonly caught ... | 2010 | 21225207 |
| effect of the saliva from different triatomine species on the biology and immunity of tlr-4 ligand and trypanosoma cruzi-stimulated dendritic cells. | triatomines are blood-sucking vectors of trypanosoma cruzi, the causative agent of chagas disease. during feeding, triatomines surpass the skin host response through biomolecules present in their saliva. dendritic cells (dcs) play a crucial role in the induction of the protection to aggressive agents, including blood-sucking arthropods. here, we evaluated if salivary components of triatomines from different genera evade the host immunity by modulating the biology and the function of lps- or t. c ... | 2016 | 27938380 |
| amazonian triatomine biodiversity and the transmission of chagas disease in french guiana: in medio stat sanitas. | the effects of biodiversity on the transmission of infectious diseases now stand as a cornerstone of many public health policies. the upper amazonia and guyana shield are hot-spots of biodiversity that offer genuine opportunities to explore the relationship between the risk of transmission of chagas disease and the diversity of its triatomine vectors. over 730 triatomines were light-trapped in four geomorphological landscapes shaping french-guiana, and we determined their taxonomic status and in ... | 2016 | 26867025 |
| prevalence and transmission of trypanosoma cruzi in people of rural communities of the high jungle of northern peru. | vector-borne transmission of trypanosoma cruzi is seen exclusively in the americas where an estimated 8 million people are infected with the parasite. significant research in southern peru has been conducted to understand t. cruzi infection and vector control, however, much less is known about the burden of infection and epidemiology in northern peru. | 2015 | 26000770 |
| ecology of rhodnius robustus larrousse, 1927 (hemiptera, reduviidae, triatominae) in attalea palm trees of the tapajós river region (pará state, brazilian amazon). | the rising number of acute cases of chagas disease in the state of pará, reported in the past two decades, has been associated, in part, with the ingestion of juice of local palm tree fruits, mainly açaí berry and bacaba. near the study area, in santarém, pará state, an outbreak of chagas disease has been notified and investigations suggest the consumption of bacaba juice as the main source of infection with t. cruzi. the purpose of this study is to assess the aspects associated to the ecology o ... | 2014 | 24690302 |
| distribution of constitutive heterochromatin in species of triatomines with fragmentation of sex chromosomes x. | cytogenetic analyses of triatomines are considered to be important taxonomic tools. thus, we analyzed the pattern of constitutive heterochromatin in 7 species of triatomine with fragmentation of the sex chromosome x, focusing on the cytotaxonomy of these triatomines. the species analyzed included triatoma vitticeps, triatoma melanocephala, triatoma tibiamaculata, triatoma protracta, meccus pallidipennis, panstrongylus megistus, and panstrongylus lignarius. the seminiferous tubules of the adult m ... | 2014 | 25501239 |
| [triatominae species] | this paper provides a checklist of 15 known species of the triatominae subfamily in maranhão state. on the coastal são luís island there are a total of 10 species associated with sylvatic areas (eratyrus mucronatus, psammolestes tertius, panstrongylus diasi) and periurban and urban areas (panstrongylus geniculatus, panstrongylus lignarius, rhodnius nasutus, rhodnius neglectus, rhodnius pictipes, rhodnius robustus and triatoma rubrofasciata). the last was found only on são luís island, while the ... | 1998 | 9592224 |
| first report of panstrongylus lignarius , walker, 1873 (hemiptera, reduviidae, triatominae), in the state of rondônia, brazil. | this study reports, for the first time, the presence of panstrongylus lignarius in the state of rondonia, brazil. | 2017 | 28954079 |
