bulinus species on madagascar: molecular evolution, genetic markers and compatibility with schistosoma haematobium.of the four species of bulinus found on madagascar, three species: b. obtusispira, b. liratus and b. bavayi are endemic while the fourth, b. forskalii, is probably a recent introduction from the african mainland. the evolutionary relationships of these species with bulinus species from africa were studied by phylogenetic analysis of dna sequence variation at two mitochondrial loci: cytochrome oxidase subunit i (coi) and large ribosomal subunit (lsu) or 16s. the observed levels of nucleotide dive ...200111769288
[validation of questionnaire methods to identify schistosoma haematobium bilharziasis hyperendemic zones in madagascar].schistosomiasis is a major public health problem in madagascar. the aim of the national control program is to reduce the morbidity in hyperendemic areas. a prospective study has been conducted in morombe and ampanihy to elaborate a simple method to identify shistosoma haematobium hyperendemic communities. the study included 1,373 children from 5 to 15 years old in 17 primary schools. moderate sensitivity and negative predictive value, with high specificity and positive predictive value of "blood ...200212643095
