Biological control studies: Bacteria associated with moribund Biomphalaria glabrata (Mollusca) in the laboratory

Abstract

The bacteria associated with moribund specimens of the gastropod Biomphalaria glabrata were identified over a 4-year period. A total of 12 species and one or more representatives of Enteric Group 17 were found. Among these, Citrobacter freundii, a common aquatic species, was associated with 99%, and Aeromonas hydrophila, a sometimes pathogenic species, was associated with 66% of the moribund snails.
