Escherichia coli (E. coli) is a normal inhabitant of the gastrointestinal tract of vertebrates, including humans. Phylogenetic analysis has shown that E. coli is composed of four main phylogenetic groups (A, B1, B2 and D). Group A and B1 are generally associated with commensals, whereas group B2 is associated with extra-intestinal pathotypes. Most enteropathogenic isolates, however, are assigne...
Background and Objective: Escherichia coli strains are the major cause of urinary tract infections which belong to the large group of extra-intestinal pathogenic E. coli. They fall into four main phylogenetic groups: A, B1, B2 and D. The aim of the present study was to determine phylogenetic groups in uropathogenic and commensal Escherichia coli isolated. Also, due to increase in the rate of an...
Phylogenetic relationships among the Eumeces schneiderii princeps and Eumeces schneiderii pavimentatus investigated using 509 bp partial sequences of 16S mitochondrial gene. Analyses were done by maximum-likelihood (RAxML) criteria on 52 specimens from over 20 geographically distinct localities. Our molecular results proposed two well-supported major clades by their phylogenetic positions, gene...

TrnL-F region including intron trnL (UAA) and trnL (UAA) - trn (GAA) spacer in the large single-copy region of the chloroplast genome is widely used to infer phylogenetic relationships in plants. In this study, we obtained the trnL-F sequences from 8 samples of Arum L. in Iran. Phylogenetic analyses were conducted by the Bayesian inference, maximum parsimony, and maximum likelihood methods. The...
Background and Aim: Uropathogenic Escherichia coli (UPEC) strains are a causative agent in most of the urinary tract infections (UTIs), which constitute a multitude of virulence factors. There is little information about phylogenetic group distribution, types, and their virulence factors in Uropathogenic Escherichia coli (UPEC) in different areas of Iran. In the present study, the phylogenic pa...
