| feeding patterns of triatoma vitticeps in the state of rio de janeiro, brazil. | feeding patterns of triatomines have contributed to elucidate its biology. triatoma vitticeps, naturally infected with t. cruzi, has been found in domiciles. its behavior and epidemiological patterns were investigated. | 2000 | 10973153 |
| major cysteine protease (cruzipain) in z3 sylvatic isolates of trypanosoma cruzi from rio de janeiro, brazil. | trypanosoma cruzi, the etiologic agent of chagas' disease, is represented by a set of parasites which circulate between man, vectors, domestic and wild animals. recently, our group isolated from triatoma vitticeps strains of t. cruzi that were characterized as belonging to the z3 phylogenetic lineage. since very little is known about the biological and/or biochemical markers of sylvatic z3 isolates, we have studied the protein and protease profiles of distinct z3 isolates designated as smm10, sm ... | 2009 | 19437041 |

| [focus of chagas disease in são fidélis, in the state of rio de janeiro]. | four specimens of triatoma vitticeps and one of panstrongylus geniculatus were caught inside a home in the municipality of são fidélis, rio de janeiro. one of the specimens of triatoma vitticeps proved positive for infection with trypanosoma cruzi. two people living in that home (one adult and one adolescent) presented positive serology. | 2008 | 18853020 |
| molecular characterization of trypanosoma cruzi sylvatic isolates from rio de janeiro, brazil. | trypanosoma cruzi, the etiologic agent of chagas disease, presents considerable heterogeneity between isolated populations within the wild and domestic cycles. by using multiplex polymerase chain reaction based on the mini-exon gene, characterization was performed on seven samples isolated from specimens of triatoma vitticeps that had been collected from the locality of triunfo in the municipality of santa maria madalena, state of rio de janeiro, brazil. the samples smm10, smm53, smm88, and smm9 ... | 2008 | 18622628 |
| [source of chagas disease in arcádia, state of rio de janeiro, brazil]. | following the report of triatomine nymphs in a house in arcadia, miguel pereira, state of rio de janeiro, brazil, the infested dwelling was checked. several eggs and 46 specimens of triatoma vitticeps (stal, 1859) were collected. among them, adults and nymphal instars accounted for 43.5% and 56.5%, respectively. analysis of blood meals showed the ecletism of this species; 24 (52.2%) were single feeds, 18 insects (39.1%) fed on two hosts and 4 (8.7%) on three hosts. trypanosoma cruzi infection ra ... | 2004 | 14762512 |
| an investigation on the ecology of triatoma vitticeps (stal, 1859) and its possible role in the transmission of trypanosoma cruzi, in the locality of triunfo, santa maria madalena municipal district, state of rio de janeiro, brazil. | from january 1989 to april 1995, 465 specimens of triatoma vitticeps were collected in the locality of triunfo, 2nd district of santa maria madalena municipal district, state of rio de janeiro. the bugs were found indoors by local residents with predominance of adults. the flight activity was high in hot months when the incidence in the domicile also increased. two hundred and two bugs (111 alive and 91 dead) were examined for trypanosoma cruzi infection. this was detected in 31 of the dead bugs ... | 1998 | 9921289 |
