[Enterobacteria isolated from commercial fishes from the Volga-Caspian basin].

Enteric bacteria, such as Proteus, Citrobacter [correction of Cytobacter], and Providencia, were found to be prevalent particularly in the gills and intestines of marketable fishes of the Volga and Caspian Seas. Half of all the enteric bacteria was detected in the fish kidneys, spleen, and liver. This shows it necessary to standardize different types of fish raw materials.
