Co-Detection of Schistosoma Mansoni and schistosoma Haematobium infections by enzyme-Linked Immunoelectrotransfer Blot Test in Brazilians after Staying in Mozambique

A group of 132 Brazilians was in Mozambique (Africa) on July and November 1994, participated in peace a mission by United Nations Organization (UNO), in an endemic area for Schistosoma mansoni (Sm) and Schistosoma haematobium (Sh) and they swum in Licungo river during leisure time. We examined 87 individuals, all of them were male and their arithmetic age was 31 year. They presented signals and symptoms such as lumbar pain, dysuria, hematuria and pollakyuria and, they did not present gastrointestinal complaints. Urine test Showed that 30 (34.5%) eliminated Sh eggs and all of them presented eosinophilia. The Enzyme-linked immunoelectrotransfer blot assay (EITB) detected positive IgM for Sm and Sh in 26 (29.9%); only for Sm in 11 (12.6%); only for Sh in 24 (27.5%) and negative for both in 14 (16.1%). The diagnosis of them is commom after exposition in the region (Africa). Some regions of Brazil are endemics to Sm but not to Sh, however there is not described autochthonous infection for Sm in Brazil. All of them with urine positive for Sh presented 100% of parasitological cure after first, second or third treatment with praziquantel.
