| genetic predisposition to self-curing infection with the protozoan leishmania chagasi: a genomewide scan. | the protozoan leishmania chagasi can cause disseminated, fatal visceral leishmaniasis (vl) or asymptomatic infection in humans. we hypothesized that host genetic factors contribute to this variable response to infection. a family study was performed in neighborhoods of endemicity for l. chagasi near natal in northeastern brazil. study subjects were assessed for the presence of vl or asymptomatic infection, which was defined by a positive delayed-type hypersensitivity (dth) skin test response to ... | 2007 | 17955446 |
