| canine visceral leishmaniasis in barra de guaratiba, rio de janeiro, brazil: assessment of risk factors. | barra de guaratiba is a coastal area of the city of rio de janeiro where american visceral leishmaniasis (avl) is endemic. although control measures including killing of dogs and use of insecticides have been applied at this locality, the canine seroprevalence remains at 25% and during 1995 and 1997 eight autochthonous human cases were notified. in order to evaluate factors related to the increase of the risk for leishmania (leishmania) chagasi infection in dogs we have screened 365 dogs by anti ... | 2003 | 12754572 |
| mixed infection with leishmania (viannia) braziliensis and leishmania (leishmania) chagasi in a naturally infected dog from rio de janeiro, brazil. | we report here the first case of co-infection with leishmania (viannia) braziliensis and leishmania (leishmania) chagasi in a naturally infected dog from rio de janeiro, brazil. isoenzyme characterisation identified the parasites isolated in culture from the cutaneous lesion as l. (v.) braziliensis and the isolates from blood and lymph node as l. (l.) chagasi. pcr analysis using specific primers followed by molecular hybridisation for direct leishmania species identification in tissue fragments ... | 2006 | 16257024 |
| evaluation of leishmania (leishmania) chagasi strains isolated from dogs originating from two visceral leishmaniasis-endemic areas in brazil using multilocus enzyme electrophoresis. | domestic dogs are the most important reservoir in the peridomestic transmission cycle of leishmania (leishmania) chagasi. the genetic variability of subpopulations of this parasite circulating in dogs has not been thoroughly analyzed in brazil, even though this knowledge has important implications in the clinical-epidemiological context. | 2011 | 21860996 |
