| evaluation of the chagas' disease vector control program in minas gerais, brazil, with special reference to triatoma sordida. | as of 1979, data gathered by the chagas' disease control program (cdcp) in the brazilian state of minas gerais indicated that triatoma infestans was the chagas' disease vector most commonly found in and around human dwellings. a decade later, however, this picture had changed, presumably as a result of control efforts; few specimens of t. infestans were collected; and triatoma sordida had become the most commonly collected vector insect. the aim of the work reported here was to assess the effect ... | 1994 | 7951364 |
| the ecology of triatoma sordida in natural environments in two different regions of the state of minas gerais, brazil. | a study was undertaken about t. sordida in the natural environment in two different regions of the state of minas gerais: itapagipe (triângulo), an area of cerrado modified by the formation of fields of pasture and agriculture, and mato verde (north) an area of transition between caatinga and cerrado with profound deforestation in the last years due to the expansion of cotton cultivation. in both regions the principal ecotopes identified were hollow trees and the bark of live or dead trees, wher ... | 1993 | 8278753 |
| [control of triatoma sordida in rural peri-domestic environment of the porteirinha municipality, minas gerais, brazil]. | triatoma sordida, a predominantly peridomestic species, is currently the triatomine species most frequently collected in brazil. to evaluate the effectiveness of control activities against this species, a survey to determine infestation rates was carried out in october 1993 in 12 rural localities in the municipality of porteirinha, state of minas gerais, brazil. in the survey, 772 t. sordida were captured, of which 3.6% were infected with trypanosoma cruzi. of the 406 dwellings investigated, 34. ... | 1998 | 9503959 |
| [chagas' disease in lassance, minas gerais state: clinical-epidemiological re-evaluation ninety years after the discovery by carlos chagas]. | the history and present situation of chagas' disease in lassance (the county where carlos chagas discovered american trypanosomiasis) were studied through a historical analysis and clinical and epidemiological research performed from 1999 to 2001. lassance was an important focus of chagas' disease from carlos chagas up until the 1980's, because of intensive infestation in dwellings by panstrongylus megistus and triatoma infestans, two important species which were efficiently controlled in the la ... | 2002 | 12011926 |
| [about the use of "maria" bio-sensors in the activities of epidemiological surveillance against chagas' disease in the north of minas gerais state]. | eight hundred and sixty six bio-sensors for the passive detection of triatomine bugs, were tried in intra-domiciles of thirteen municipalities of an endemic area of triatoma sordida in the north of minas gerais state, brazil. this species is nowadays the most captured in brazil and mainly in the above region. the sensors were examined every three months, corresponding to four times in the first seven municipalities (six hundred and forty two sensors, with a maximum positivity of 0.5%) and two ti ... | 2005 | 16172750 |
