水産食品による食中毒の研究-I

Abstract

The proceeding paper considered that the food poisoning by octopus was caused by poisonous substance produced by bacterial action. MIURA et al2) reported previously that the food poisoning by fresh water shrimp, Paratya compressa (improvisa Kemp), was supposed to be induced by the toxic substance produced by a strain of Proteus. This shrimp food poisoning occured in the near place of food poisoning by octopus. Hereupon author isolated some bacteria (Table 1, Fig. 1) from the fresh water shrimp caught in this area and studied to know whether a strain of these bacteria (thought belong to the same group as the isolated by MIURA et al), toxicate octopus or not. The results obtained are as follows: (1) Toxic substance is producible on octopus or its 80% methanol extracts by the action of Rettgerella like bacteria (Table 3). (2) Toxic substance is extractable by water and 80% methanol.
