Association of antibiotic resistance and biofilm formation in Escherichia coli ST131/O25b.

Acta Microbiologica et Immunologica Hungarica
Urinary tract infections are becoming difficult to treat every year due to antibiotic resistance. Uropathogenic Escherichia coli (UPEC) isolates pose a threat with a combined expression of multidrug-resistance and biofilm formation. ST131 clone is a high-

Extended-spectrum beta-lactamase- and carbapenemase-producing Escherichia coli isolates causing hospital- and community-acquired infections in Tunisia (2001–2019): expansion of CTX-M-15-C2 and CTX-M-27-C1 ST131 subclades

Microbiology spectrum
The prevalence of infections caused by extended-spectrum beta-lactamase (ESBL)-producing Escherichia coli (ESBL-EC) and carbapenemase-producing E. coli (CP-EC) is increasing worldwide.

High Occurrence of ST131 Among Extraintestinal Pathogenic Escherichia coli in Humans and Dogs in Sri Lanka

Zoonoses and Public Health
Extraintestinal pathogenic Escherichia coli (ExPEC) is an important human and animal pathogen. In particular, the ST131 of ExPEC is a widely distributed clone, resistant to extended‐spectrum cephalosporins and fluoroquinolones.

[Bloodstream infections with Escherichia coli O16-ST131 and O25b-ST131: molecular epidemiology, phylogenetic analysis and antimicrobial resistance].

Nan fang yi ke da xue xue bao = Journal of Southern Medical University, 2019
To investigate the phylogenetics and prevalence of bloodstream infections with Escherichia coli ST131, the antimicrobial resistance profiles of the pathogens, and the clinical features.Non-duplicate Escherichia coli isolates were collected from 144 patients with bloodstream infections in our hospital between January and December, 2016.The phylogenetic ...

Characterization of ESBL-producing Escherichia coli ST131 isolates from Port Elizabeth

Diagnostic Microbiology and Infectious Disease, 2015
This study investigated resistance determinants and genetic relatedness in extended-spectrum beta-lactamase (ESBL)-producing Escherichia coli isolates. PCR and DNA sequencing were used for screening isolates for blaCTX-M, blaTEM, and blaSHV (qnrA, qnrB, qnrC, qnrD, qnrS, aac(6)-lb-cr, and qepA) resistance genes and the sequence type 131 (ST131) clone ...

Prevalence and characteristics of ST131-O16 and ST131-O25b clones among extended-spectrum β-lactamase-producing Escherichia coli isolates causing bloodstream infection in Iran

Molecular Biology Reports
The multidrug-resistant clone identified as Escherichia coli sequence type 131 (E. coli ST131) has spread worldwide. The current study is one of the first comprehensive investigations to ascertain the prevalence of ST131 and molecularly characterize the ST131-O25b and ST131-O16 subgroups causing bloodstream infections in Iran.To this end, 119 ...
