title: [Toxoplasma gondii in Haiti. Results of a sero-epidemiologic survey in a rural area].
abstract: In Haiti, positive immunofluorescent tests are observed in 5.9% of the inhabitants of a rural area in the South of the country. The index of positive reactions is increasing with age. No difference between males and females is noticed. Seropositive cases are clustered within defined families for 60% of them. The antibodies titers are low: 8 I. U. for 88% of cases. The prevalence of toxoplasmosis varies from 0 to 15%, according to the village, without any clear relationship with rainfall, altitude, or prevalence of intestinal worm infections. Subjects harboring nematodes transmitted by skin penetration are more often serologically positive than others. Oocysts voided by cats seem to be mainly responsible for transmission to humans in this part of the world.
