A year long survey on the ecology of Salmonella and the correlation of bacterial indicators of pollution in the isolation of this enteric pathogen were studied. MPN procedure were employed for the enumeration of total viable counts, total coliforms, fecal coliforms and fecal streptococci in surface waters of riverine and marine biotopes of Fukuyama, Japan. A modified primary, nonselective, elevated temperature preenrichment procedure was used in detecting MPN indices of Salmonella. From the results, it could be suggested that bacterial indicators of pollution were not reliable as an index of microbial quality of aquatic system and emphasised that direct enumera-tion of Salmonella could serve as an indicator of the quality of water. Serological studies of 321 strains of Salmonella yielded 11 serotypes with one untypable strain. S. agona, S. champaign and S. litchfield were first isolated in Fukuyama aquatic environment. In addition, one new serotype viz. S. III b 58:z10:z53:Rz50 was first time reported during the present study.
