Table 2. Schistosoma mansoni genetic diversity as estimated at a partial fragment of the cytochrome c oxidase subunit 1 gene.
Genetic diversity was estimated for samples obtained from Senegal and eight other African countries (see Table 1 for details on data collection). Sequences that were sampled in other countries than Senegal were pooled per country.
