Phylogenetic analysis of Escherichia coli strains isolated from human samples
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...
متن کاملPhylogenetic typing and detection of extended-spectrum β-lactamases in Escherichia coli isolates from broiler chickens in Ahvaz, Iran
This study was conducted to reveal the phylogenetic background, to detect the genes encoding TEM, SHV and CTX-M-15 extended-spectrum β-lactamases (ESBL), and to analyze their distribution in phylo-groups of 150 Escherichia coli isolates from broiler chickens in Ahvaz (Southwest of Iran). Seventy- five cloacal swabs from healthy birds (fecal isolates), and 75 heart blood samples from bi...
متن کاملClonal analysis and virulent traits of pathogenic extraintestinal Escherichia coli isolates from swine in China
BACKGROUND Extraintestinal pathogenic Escherichia coli (ExPEC) can cause a variety of infections outside the gastrointestinal tract in humans and animals. Infections due to swine ExPECs have been occurring with increasing frequency in China. These ExPECs may now be considered a new food-borne pathogen that causes cross-infections between humans and pigs. Knowledge of the clonal structure and vi...

متن کاملPhylogenetic group determination of faecal Escherichia coli and comparative analysis among different hosts
Phylogenetic analysis has shown that Escherichia coli is composed of four main phylogenetic groups (A, B1, B2 and D). Characterization of phylogenetic groups is of clinical interest, as group A and B1 generally associated with commensals, whereas most enteropathogenic isolates are assigned to group D, and group B2 is associated with extra-intestinal pathotype. One hundred E. coli strains recove...
