title: [New records of bacteria-spirochetes in crystalline style of fresh water gastropods].
abstract: Freshwater mollusks belonging to 17 species, in 7 families are examined purposely to search for spirochete bacteria in their crystalline style of the digestive system. As result of this study spirochetes are recorded in gastropod families Amnicolidae, Bithyniidae, Baicaliidae and Benedictiidae, represented by 12 species, occupying different habitats. Gastropods belonging to Valvatidae, Lymnaeidae and Planorbidae, characterized by lack of crystalline style did not include spirochetes in their stomachs. Studied gastropods having spirochetes or free of them are grazers or filter-feeders and mainly phyto-detrito-bacteriaphagous.
