| isoenzymes detect variation in populations of triatoma brasiliensis (hemiptera: reduviidae: triatominae). | triatoma brasiliensis is one of the most important vectors of chagas disease in the semiarid zone of the northeast of brazil. intraspecific morphological and behavioural variation has been reported for different populations. results for four distinct populations using eight isoenzymes are reported here. the literature describes three subspecies: t. brasiliensis brasiliensis neiva, 1911; t. brasiliensis melanica neiva & lent, 1941 and t. brasiliensis macromelasoma galvão, 1956. these subspecies d ... | 1997 | 9361737 |
| ecotopes, natural infection and trophic resources of triatoma brasiliensis (hemiptera, reduviidae, triatominae). | triatoma brasiliensis is considered as one of the most important chagas disease vectors in the northeastern brazil. this species presents chromatic variations which led to descriptions of subspecies, synonymized by lent and wygodzinsky (1979). in order to broaden bionomic knowledge of these distinct colour patterns of t. brasiliensis, captures were performed at different sites, where the chromatic patterns were described: caicó, rio grande do norte (t. brasiliensis brasiliensis neiva, 1911), it ... | 1998 | 9698835 |
| survey for trypanosoma cruzi infection in a municipality in northeast brazil. | an epidemiological survey of trypanosoma cruzi infection was carried out in bodocó, located in the western part of the state of pernambuco, brazil. two hundred and forty-one individuals were parasitologically and immunologically screened. although hemoculture did not reveal the presence of parasites in the blood, the sera of 5 individuals were scored as positive by the indirect fluorescence antibody test and the enzyme-linked immunosorbent assay. seropositivity in individuals above and below the ... | 1999 | 10733161 |
