| epidemiology of chagas disease in jaguaruana, ceará, brazil. i. presence of triatomines and index of trypanosoma cruzi infection in four localities of a rural area. | in order to assay the triatomine infestation and domiciliation in the rural area of jaguaruana district, state of ceará, brazil, we studied, from november 2000 to april 2002, 4 localities comprising 158 domiciles as a whole, with an average of 4 inhabitants/house, who are dwelling in there for more than 7 years. most houses have tile-covered roofs and the walls built with plaster-covered bricks (57%), followed by bricks without plaster (33%), and mud walls (7.5%). a total of 3082 triatomines wer ... | 2004 | 15273797 |
| [occurrence of panstrongylus lutzi, in peridomiciliary areas, state of ceará, brazil]. | from january 2001 to october 2002 captures were made in domicile and peridomiciliary areas of 13 cities of region of cariri, south of the state of ceará. as results, the occurrence of p. lutzi in this area was noticed, for the first time, in three cities: the presence of one adult in chicken house in altaneira, one adult flying, in salitre and 18 nymphs in varzea alegre(13 in bricks pile and five in roofing tile pile). in varzea alegre city it was observed the colonization in the peridomicile. | 2004 | 15311300 |
| aspects of peridomiciliary ecotopes in rural areas of northeastern brazil associated to triatomine (hemiptera, reduviidae) infestation, vectors of chagas disease. | artificial ecotopes of 121 peridomiciliary environments in four rural localities in the state of ceará, brazil, were studied and the type of material of the ecotopes was identified as triatomine infestation. two thousand two hundred and four triatoma brasiliensis neiva, 340 triatoma pseudomaculata corrêa and espínola, 121 rhodnius nasutus stall, and 5 panstrongylus lutzi (neiva and pinto) were captured. out of the 323 ecotopes found (x = 2.0 +/- 1.8 per dwelling) - such as pigpens, henhouses, co ... | 2006 | 16830706 |
| [feeding sources evaluation of panstrongylus lutzi (neiva & pinto, 1923) (hemiptera: reduviidae: triatominae) in the state of ceará]. | the authors used precipitin technique to detect the feeding sources of panstrongylus lutzi (neiva & pinto, 1923) in 20 municipalities of ceará state, brazil. the results detected the presence of blood from eight different blood sources and mixed feedings, demonstrating that panstrongylus lutzi is an eclectic species. high infection rates for trypanosoma like-cruzi were detected. | 2006 | 17119749 |
| occurrence and variability of panstrongylus lutzi in the state of ceará, brazil. | panstrongylus lutzi is generally restricted to the "caatinga" areas of north-eastern brazil. adult insects are frequently found in local houses, but colonies have not previously been registered in the statistics of the control programme of chagas disease. in ceará state, our study revealed increasing occurrence of this species, usually with high infection rates for trypanosoma cruzi, and always represented by adults that invaded the artificial environment. we also found nymphs in the peridomicil ... | 2005 | 16172758 |
