| [operational aspects of triatoma brasiliensis control]. | vector control strategies against indigenous species is not easy, due to their capacity to reinvade treated premises from sylvatic ecotopes. between august 1996 and december 1997 we conducted a study on reinfestation of houses after spraying in a county in the state of ceará. of 277 houses examined, 113 (40.8%) were infested (21.7% intradomiciliary and 35.4% peridomiciliary). of the 433 triatominae collected, 207 were triatoma brasiliensis (49% of which intradomiciliary, with a mean of 1.8 insec ... | 2000 | 11119320 |
| [focal and total residual insecticide spraying to control triatoma brasiliensis and triatoma pseudomaculata in northeast brazil]. | to efficiently control the triatomines triatoma brasiliensis and triatoma pseudomaculata, a field trial was performed to compare conventional versus focal spraying of deltamethrin 5% sc at 25 mg a. i./m2 and the slow-release organophosphate malathion 8.3% sr at 2g a. i./m2. the assay took place in the county of boa viagem, ceará state, with 1541 households, randomly separated into 4 groups. two of them received focal spraying: pt, treated with deltamethrin indoors and in the peridomicile, and pl ... | 2000 | 11119328 |
| [influence of anthropic habits in the dispersion of triatoma pseudomaculata corrêa & espínola, 1964 through mimosa tenuiflora (willdenow) (mimosaceae) in the state of ceará, brazil]. | triatoma pseudomaculata was captured in the phloem of the black acacia bush (mimosa tenuiflora) in seven municipalities in the state of ceará, brazil. this bush is widespread in the caatinga (scrub forest) and is used extensively by the rural population for kindling. peridomiciliary presence of triatomines in the cariri region may be associated with the use of infested m. tenuiflora wood by the population, thus facilitating the triatomines' mobilization and dispersion. | 2004 | 15029337 |
| [feeding patterns of triatoma pseudomaculata in the state of ceara, brazil]. | t. pseudomaculata, a peridomicilar species, has low rates of t. cruzi infection. the occurrence of this triatomine in the domicile and its feeding patterns was investigated to identify potential t. cruzi reservoirs. | 2005 | 15654457 |
| 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 |
| genetic polymorphism in trypanosoma cruzi i isolated from brazilian northeast triatomines revealed by low-stringency single specific primer-polymerase chain reaction. | different molecular markers have been employed for typing trypanosoma cruzi strains from endemic areas of chagas disease. the low-stringency single specific primer-polymerase chain reaction (lssp-pcr) has been a sensitive and informative technique that uses the variable region of kinetoplast dna minicircles as a genetic marker, allowing detection of dna sequence variation. in the present study, we analyzed the intra-lineage genetic variability of the t. cruzi strains obtained from triatomine fec ... | 2008 | 18633644 |
| [epidemiology of chagas disease in four rural localities in jaguaruana, state of ceará: seroprevalence of infection, parasitemia and clinical characteristics]. | a cross-sectional study on chagas disease that examined the populations of four localities (n masculine = 541 inhabitants) in the municipality of jaguaruana, state of ceará, showed seroprevalence of chagas infection of 3.1%, as assessed by indirect immunofluorescence, indirect hemagglutination and elisa tests. the rate was higher among adults over 50 years old, without any difference in relation to sex. positive parasitemia was found in 11.8% (2/17) of the seropositive individuals by means of in ... | 2008 | 18853005 |
| surveillance of chagas disease vectors in municipalities of the state of ceará, brazil. | the present study aimed to analyse the dwelling infestation rates and the distribution and natural trypanosoma cruzi infection rates, among triatomines captured in the 13 municipalities of the state of ceará. the records relating to the capture of intradomicile and peridomicile triatomines during the chagas disease control program of 1998-2008 were available. among the triatomines captured and in all of the municipalities studied, triatoma brasiliensis presented the highest incidence in intradom ... | 2009 | 20140377 |
