抄録

Seasonal variation in numbers of histamine-forming bacteria was investigated for a one year period in the water samples collected bimonthly from 3 inshore stations in Tokyo Bay and Sagami Bay. Histamine-forming bacteria isolated from these water samples by using histidine broth were classified into 3 types in respect to growth-temperature/salinity: psychrophilic halophitic group, mesophilic halophilic group, and nonhalophilic group. Psychrophilic halo-philic group bacteria were found at the level of 10-102/10l from autumn to the following spring. Mesophilic halophilic group bacteria were detected 10-103/10l from early summer to autumn when water temperatures rose above 20°C. From the taxonomic characteristics, psychrophilic halophilic histamine-forming bacteria were identified with N-group bacteria. But mesophilic halophilic histamine-formers, which can produce as much histamine as Proteus morganii can, could not be identified with any known species.
