从新鲜和冷藏的肉鸡皮肤中分离到假单胞菌。表型为基础的数值分类技术被用来表征的菌株和36个参考菌株。为此，使用了Biolog GN微孔板、API 20 NE和许多其他生化试验。Jaccard聚类显示四个主要假单胞菌群的优势：Ps。真菌，Ps，lundensis，Ps.荧光菌biovars和一个身份不明的一组菌株显示出高度的相似性Ps。荧光菌生物群，在Ps内。荧光菌，生物变种A是最好的代表。Ps的成员具有显著的蛋白水解特征。荧光菌biovars A，B和C，以及成员的身份不明的集群，支持其可能的作用，在感官缺陷的起源，在Ps。lundensis cluster，一个独立的Ps.进一步的基因型研究将有助于进一步阐明Ps的分类地位。lundensis-like菌株和类似Ps的未鉴定组。florescens biovars A和B。
Pseudomonas strains were isolated from both fresh and cold-stored broiler skin. Phenotypically-based numerical taxonomic techniques were used to characterize the isolates and 36 reference strains. For this purpose, Biolog GN Microplates, API 20NE and a number of other biochemical tests were used. Jaccard clustering revealed the predominance of four major Pseudomonas groups: Ps. fungi, Ps, lundensis, strains belonging to Ps. fluorescens biovars and an unidentified group of strains displaying a high degree of similarity to Ps. fluorescens biovars, Within Ps. fluorescens, biovar A was best represented. The marked proteolytic character of members of Ps. fluorescens biovars A, B and C, as well as of members of the unidentified cluster, supports their possible role in the origin of organoleptic defects, In the Ps. lundensis cluster, a distinct group of Ps. lundensis-like species was found. Further genotypic studies should be carried out to clarify the taxonomic status of the Ps. lundensis-like strains and that of the unidentified group resembling Ps. florescens biovars A and B.
