| developmental stages of trypanosoma cruzi-like flagellates in cavernicola pilosa. | the developmental stages of trypanosoma cruzi ssp., found in the intestinal tract of cavernicola pilosa, are described and measurements given for nine life stages. the frequencies of the various stages in foregut, midgut and hindgut of the triatomines are provided; parasites were rare in the foregut and metatrypomastigotes were seen only in the mid- and hindguts. all adult bugs examined harboured intestinal infections of t. cruzi-like flagellates, large clumps of amastigotes were frequently obse ... | 1982 | 6820697 |
| epidemiology of chagas disease in ecuador. a brief review. | chagas disease is a complex public health problem that has been underestimated in ecuador. here we review the relevant published information, and present unpublished and new data that help to understand the current chagas disease epidemiological situation and its evolution in the country. three main characteristics have been identified: (i) persistence of trypanosoma cruzi transmission in already known foci; (ii) a marked endemicity in some urban areas of guayaquil; and (iii) the transformation ... | 1999 | 10677762 |
| 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 |
| the triatominae species of french guiana (heteroptera: reduviidae). | an annotated list of the triatomine species present in french guiana is given. it is based on field collections carried out between 1993-2008, museum collections and a literature review. fourteen species, representing four tribes and six genera, are now known in this country and are illustrated (habitus). three species are recorded from french guiana for the first time: cavernicola pilosa, microtriatoma trinidadensis and rhodnius paraensis. the two most common and widely distributed species are ... | 2009 | 20140371 |
| bats, trypanosomes, and triatomines in ecuador: new insights into the diversity, transmission, and origins of trypanosoma cruzi and chagas disease. | the generalist parasite trypanosoma cruzi has two phylogenetic lineages associated almost exclusively with bats-trypanosoma cruzi tcbat and the subspecies t. c. marinkellei. we present new information on the genetic variation, geographic distribution, host associations, and potential vectors of these lineages. we conducted field surveys of bats and triatomines in southern ecuador, a country endemic for chagas disease, and screened for trypanosomes by microscopy and pcr. we identified parasites a ... | 2015 | 26465748 |
| [attalea butyracea palms adjacent to housing as a source of infestation by rhodnius prolixus (hemiptera: reduviidae)]. | the presence of rhodnius prolixus in palms on the eastern plains area of colombia provide a high risk for infection with trypanosoma cruzi. intensive surveillance of the palm tree habitat are necessary to confirm the presence of bugs and provide evidence that this habitat is a source of house infestations. | 2012 | 23242302 |
| first cytogenetic study of cavernicola pilosa barber, 1937 (hemiptera, triatominae). | cavernicola pilosa is a triatomine species that lives in caves and feeds on bat blood. this vector has a wide geographical distribution, and is found in brazil, colombia, panama, peru, and venezuela. little is known about the reproductive biology of this species, because most previous studies have only characterized its morphology, morphometry, ecology, and epidemiology. therefore, this study aimed to obtain preliminary data related to spermatogenesis in c. pilosa by conducting cytogenetic analy ... | 2015 | 26535704 |
