attempts to improve xenodiagnosis: comparative test of sensibility using rhodnius neglectus, panstrongylus megistus, triatoma vitticeps and triatoma infestans in endemic areas of brazil. | from june 1984 to july 1992, 392 xenodiagnostic tests were applied on 264 patients with chronic chagas disease from brazilian endemic areas of virgem da lapa and coronel murta, situated in the jequitinhonha valley, in the state of minas gerais. the susceptibilities of rhodnius neglectus, panstrongylus megistus, triatoma vitticeps and triatoma infestans were compared. most of the time 20 nymphs (fourth instar) of each species were applied to 161 women and 103 men aged between 5 and 83 years of ag ... | 1997 | 9302418 |
population dynamics of triatoma vitticeps (stål, 1859) in itanhomi, minas gerais, brazil. | taxonomic markers (head structure morphometry, isoenzymes and randon amplified polymorphism of dna - rapd) were used to understand the population dynamics of triatoma vitticeps, predominant triatomine species in itanhomi district, using samples obtained from domestic, peridomiciliary and sylvatic habitats. morphometric analysis revealed sexual dimorphism within the three samples although specimens could not be separated according to the habitat in which they were captured. forty-two bands were a ... | 2008 | 18368232 |
analysis of the geographical distribution of triatoma vitticeps (stål, 1859) based on data of species occurrence in minas gerais, brazil. | the purpose of this study was to determine the potential for infestation of man-made environments by triatoma vitticeps, correlating the epidemiological importance of this species with that of others present in the brazilian state of minas gerais. in addition, climatic variables that could help explain the distribution of this species and clarify its population dynamics were sought. this was done by carrying out a historical survey of the presence of t. vitticeps in artificial ecotopes, using da ... | 2010 | 20493970 |
