【Abstract】 In Recent four years, 13 strains of phage of Bacillus cereus have been isolated from water in order to do some phage typing.After purifieation and multiplication, these phages must be diluted to their R.T.D. before test.723 strains of Bacillus cereus were presented from 16 different regions in China（121 of which are food poisoning causative agents and 602 from general food）. The preliminary results show that the type C29, C30, C24, C27, G19 and A4 were in the relatively majority.Among the 121 strains of poisoning causative agents, of which 75% are typable and the A₄ is the most common type（10/91）.更多还原
