| infestation of arboreal nests of coatis by triatomine species, vectors of trypanosoma cruzi, in a large neotropical wetland. | the coati (nasua nasua, carnivora) is a medium-sized mammal common in the pantanal of brazil. unlike most mammals, coatis construct arboreal nests used for resting and reproduction. in this region, the coati is an important host of trypanosoma cruzi, the causative agent of chagas disease. there are two possible routes through coatis can be infected by t. cruzi: the oral route or the vectorial route. however, the relative importance of each of these routes in the infection of coatis and its role ... | 2015 | 26611974 |
| first report of rhodnius stali (hemiptera, reduviidae, triatominae) in the state of acre and in the brazilian amazon. | this paper reports, for the first time, the presence of rhodnius stali in the state of acre and in the brazilian amazon. | 2017 | 27384836 |
| infestation of peridomestic attalea phalerata palms by rhodnius stali, a vector of trypanosoma cruzi in the alto beni, bolivia. | to determine (i) whether peridomestic attalea phalerata palms in fragmented human-occupied areas of the alto beni, bolivia, are infested by triatomines; (ii) the specific status of triatomines captured in the area; and (iii) the rate of natural trypanosoma cruzi infection among those triatomines. | 2010 | 20374565 |
| comparative descriptions of eggs from three species of rhodnius (hemiptera: reduviidae: triatominae). | the authors describe and compare the morphological and ultrastructural characteristics of eggs from the three most recent described species of the genus rhodnius stål, 1859, which have not previously been studied. these species are rhodnius colombiensis (mejia, galvão & jurberg 1999), rhodnius milesi (carcavallo, rocha, galvão & jurberg 2001) and rhodnius stali (lent, jurberg & galvão 1993). the results revealed that there are similarities in the exochorial architecture of optical microscopy and ... | 2009 | 20027470 |
| trypanosoma rangeli isolates of bats from central brazil: genotyping and phylogenetic analysis enable description of a new lineage using spliced-leader gene sequences. | trypanosoma rangeli infects several mammalian orders but has never confidently been described in chiroptera, which are commonly parasitized by many trypanosome species. here, we described trypanosomes from bats captured in central brazil identified as t. rangeli, t. dionisii, t. cruzimarinkellei and t. cruzi. two isolates, tra643 from platyrrhinus lineatus and tra1719 from artibeus planirostris were identified as t. rangeli by morphological, biological and molecular methods, and confirmed by phy ... | 2009 | 19063857 |
| domiciliation process of rhodnius stali (hemiptera: reduviidae) in alto beni, la paz, bolivia. | we report a systematic collection of triatominae inside houses and in the peridomestic environment of alto beni, department of la paz, bolivia. this area is free of triatoma infestans and although we detected previously seropositivity for trypanosoma cruzi, the alto beni region is not officially considered as endemic for chagas disease. from 11 houses of five localities, we collected adults, nymphs and eggs of a rhodnius species, which was confirmed by morphological and morphometric analysis as ... | 2003 | 12631318 |
| adult and nymphs of microtriatoma trinidadensis (lent, 1951) (hemiptera: reduviidae) caught from peridomestic environment in bolivia. | this is the first report of adult and nymphs (20 nymphs of all stages and 4 adults) of microtriatoma trinidadensis (lent 1951) (hemiptera: reduviidae: triatominae) collected in peridomestic environment, in the department of la paz, bolivia. these specimens were associated to rhodnius stali lent, jurberg & galvão 1993. the exceptional finding of m. trinidadensis in peridomestic environment, illustrates the general tendency of triatominae to adapt to human dwellings and dependences. | 2001 | 11685250 |
| on triatomines, cockroaches and haemolymphagy under laboratory conditions: new discoveries. | for a long time, haematophagy was considered an obligate condition for triatomines (hemiptera: reduviidae) to complete their life cycle. today, the ability to use haemolymphagy is suggested to represent an important survival strategy for some species, especially those in genus belminus. as eratyrus mucronatus and triatoma boliviana are found with cockroaches in the blaberinae subfamily in bolivia, their developmental cycle from egg to adult under a "cockroach diet" was studied. the results sugge ... | 2016 | 27706376 |
| trypanosoma cruzi discrete typing units (dtus): microsatellite loci and population genetics of dtus tcv and tci in bolivia and peru. | trypanosoma cruzi, the agent of chagas disease, is usually subdivided into six discrete typing units (dtus), tci to tcvi, among which tci and tcv are most common in human infections in bolivia. multilocus microsatellite typing (mlmt) was selected to further explore the structure of the natural populations belonging to these dtus. the analysis showed that microsatellite clustering does not fully match the six dtus, but it is relevant for the within dtus analyses. population genetics analysis was ... | 2011 | 21801854 |
| rhodnius stali: new vector infected by trypanosoma rangeli (kinetoplastida, trypanosomatidae). | rhodnius stali infection by trypanosoma rangeli is reported in this study for the first time. | 2018 | 29340462 |
| molecular identification of wild triatomines of the genus rhodnius in the bolivian amazon: strategy and current difficulties. | the amazon region has recently been considered as endemic in latin america. in bolivia, the vast amazon region is undergoing considerable human migrations and substantial anthropization of the environment, potentially renewing the danger of establishing the transmission of chagas disease. the cases of human oral contamination occurring in 2010 in the town of guayaramerín provided reasons to intensify research. as a result, the goal of this study was to characterize the species of sylvatic triato ... | 2017 | 28274885 |
