[Collection of mollusk intermediate hosts of Schistosoma at two sites in Lampsar (Senegal River valley): quantitative reproducibility]. / Collecte quantitative de mollusques hôtes intermédiaires de Schistosomes dans deux sites sur le Lampsar (Vallée du Fleuve Sénégal).

We studied the number of mollusks collected according to a specific protocol: 2 samplers prospecting in opposite directions for 1 min 30 s at 10 collection points regularly distributed on the site, for a total of 2 times 15 minutes. Because of the good reproducibility of the results of these collections, this method can be used for quantitative studies. A sampling effect was noted.
