Abstract

NUMERICAL TAXONOMY OF ENTEROBACTER SPP. ISOLATED FROM DIFFERENT AREAS IN SOUTH IRAQ

Ghosoon Al-Kanaany* and Yahia Al-Khafaji

ABSTRACT

A numerical classification study was carried out on 153 strains of Enterobacter using 64 unit characters including: cell characteristic, growth features, tolerance, biochemical and antibiotic susceptibility. The data were examined using the simple matching (SSM), and clustering was achieved using unweighted pair group average linkage method (UPGMA). The results of the analyses were arranged in the form of dendrogram according to the similarity matrix. At similarity level (83%), all isolates were divided into five groups, the major group was comprised of 80 isolates belong to species Enterobacter cloacae. Group 3 was composed of 67 isolates belong to species E. aerogenes. Group 5 was composed of 4 isolates representing the species: E. sakazakii, and two group (2,4) contain only one isolate representing the species Enterobacter hormaechei and E. asburiae respectively.
