摘　　要：用ｒＤＮＡ指纹图对４２株椰酵假单胞菌进行核糖型分类，探讨该菌的产毒力与核糖型分布之间的关系。结果表明，７３．８％的菌株具有产毒力，它们分布在大多数核糖型中，来源于食物中毒样品及正常食物样品。而产毒力阴性菌株只占２６．２％，它们集中于少数核糖型中，而且都来源于正常食物样品。多个克隆产毒力阳性菌株的广泛存在，提示对该菌的潜在性危害应引起足够的重视。By rDNA fingerprinting technique, ribotype discrimination analysis was conducted for exploring the relationship between the toxigenicity and ribotype distribution of 42 strains of Pseudomonas cocovenenans subsp. farinofermentans. The results showed that 73.8 percent of the strains were toxigenic, which were distributed within the most ribotypes and isolated from either food poisoning samples or normal food samples. The other strains were not toxigenic, which were isolated from normal food samples and distributed only within a few ribotypes. Since the most clones of P.cocovenenans subsp. farinofermentans  were toxigenic, their potential hazard should be concerned.
