Global Escherichia coli Sequence Type 131 Clade with blaCTX-M-27 Gene
The Escherichia coli sequence type (ST) 131 C2/H30Rx clade with the blaCTX-M-15 gene had been most responsible for the global dissemination of extended-spectrum β-lactamase (ESBL)-producing E. coli. ST131 C1/H30R with blaCTX-M-27 emerged among ESBL-producing E. coli in Japan during the late 2000s. To investigate the possible expansion of a single clade, we performed whole-genome sequencing for ...

متن کاملComplete Genome Sequence of Escherichia coli 81009, a Representative of the Sequence Type 131 C1-M27 Clade with a Multidrug-Resistant Phenotype
The sequence type 131 (ST131)-H30 clone is responsible for a significant proportion of multidrug-resistant extraintestinal Escherichia coli infections. Recently, the C1-M27 clade of ST131-H30, associated with blaCTX-M-27, has emerged. The complete genome sequence of E. coli isolate 81009 belonging to this clone, previously used during the development of ST131-specific monoclonal antibodies, is ...

متن کاملFrequency of selected virulence-associated genes in intestinal and extra-intestinal Escherichia coli isolates from chicken
Background: Although Escherichia coli (E. coli)is a part of intestinal normal microflora of warm-blooded animals, includingpoultry, outbreaks occur in poultry raised below standard sanitation and duringthe course of respiratory or immunosuppressive diseases. Avian pathogenic E.coli (APEC) harbors several genes associated with virulence andpathogenicity. APEC strains are responsible for some dis...
