Abstract
Objectives. In 2013, Clermont classified E. coli strains into eight phylogenetic groups using a new quadruplex PCR method.The aims of this study were to identify the phylogenetic groups of E. coli based on thismethod and to assess their antibiotic resistance patterns in Bushehr, Iran. Methods. In this cross-sectional study, 140 E. coli isolates were subjected to phylogenetic typing by a quadruplex PCR method. Antimicrobial susceptibility testing was performed by disk diffusion method. Results. Phylogenetic group B2 was most predominant (39.3%), followed by unknown (27.1%), E (9.3%), C and clade I (each 6.4%), B1 (5%), F and D (each 2.9%), and A (0.7%).The most common antibiotic resistance was related to amoxicillin (82.1%) and the least to meropenem (0.7%). 82.14% of isolates weremultiple drug resistant (MDR).Antibiotic resistancewasmainly detected in group B2 (50%). Conclusions. Our findings showed the high prevalence of MDR E. coli isolates with dominance of group B2. About 25% of E. coli isolates belong to the newly described phylogroups C, E, F, and clade I. Such studies need to be done also in other regions to provide greater understanding of the antibiotic resistance pattern and the prevalences of different phylogenetic groups
