We report here the draft genome sequence of the CTX-M-166-harboring O6:H16 sequence type 48 (ST48)-fimH34 Escherichia coli strain recovered from a Gallus gallus broiler. Sequence analyses revealed the presence of an IncI1/ST103-ISEcp1-blaCTX-M-166-orf477 plasmid region and of diverse antibiotic resistance and virulence-acquired genes.
Klebsiella pneumoniaesequence type (ST) 307, carryingblaKPC-3,blaCTX-M-15,blaOXA-1,aac(6')-Ib-cr, andqnrB1 genes, is replacing the predominant hyperepidemic ST258 clone in Italy. Whole-genome and complete plasmid sequencing of one ST307 strain was performed and new features were identified.
Real-time PCR testing for blaKPC, blaNDM, blaVIM, blaIMP, and blaCTX-M was performed on rectal swabs obtained from residents of two long-term acute-care facilities. While blaKPC was detected in 69/102 swabs (67.6%), testing for four other targets increased the positivity rate for a broad-spectrum β-lactamase to 73.5% (McNemar's P = 0.03).
We describe here the whole-genome sequence and basic characteristics of Escherichia coli isolate 15-AB01393, recovered from German beef within a national monitoring program in 2015. This isolate was identified as an extended-spectrum-β-lactamase-producing E. coli strain of multilocus sequence type (MLST) ST58 harboring the antimicrobial resistance genes blaCTX-M-1, mph(A), sul2, dfrA5, strA, an...
Here, we report the first autochthonous cases of infections caused by blaNDM-5 New Delhi metallo-β-lactamase-producing Escherichia coli strains recovered from urine and blood specimens of three patients from Algeria between January 2012 and February 2013. The three isolates belong to sequence type 2659 and they coexpress blaCTX-M-15 with the blaTEM-1 and blaaadA2 genes.
We present here the full-genome sequence of Escherichia coli K-15KW01, an extended-spectrum-β-lactamase-producing uropathogenic strain. Assembly and annotation of the draft genome resulted in a 5,154,641-bp chromosome and revealed a chromosomally contained blaCTX-M-15 gene embedded at the right-hand extremity of an ISEcp1 element in a plasmid-like structure (36,907 bp).
The aim of this study was to characterize the prevalence of extended-spectrum β-lactamase (ESBL) genes and plasmid-mediated fluoroquinolone resistance (PMQR) determinants in 202 Escherichia coli isolates from chickens in Anhui Province, China, and to determine whether ESBL and PMQR genes co-localized in the isolates. Antimicrobial susceptibility for 12 antimicrobials was determined by broth mic...
CTX-M-15, recently detected in Portugal, is an extended-spectrum -lactamase (ESBL) that has spread worldwide (3, 4, 9, 10, 15). The basis for the successful dissemination of blaCTX-M-15 is unknown, although the spread of epidemic Escherichia coli strains and/or conjugative plasmids harboring blaCTX-M-15 has been documented (3, 6). We report the dissemination of blaCTX-M-15 associated with strai...
Extended-spectrum β-lactamase (ESBL)-producing Escherichia coli and Klebsiella pneumoniae are the leading causes of hospital-associated infections, but community-acquired cases are increasingly being reported. This study determined the prevalence of ESBL-producing E. coli and K. pneumoniae carriers, their bla genes and risk factors of 452 patients admitted to the emergency room (ER) of Ramathib...
The aim of this study was to evaluate the population dynamics of CTX-M-producing Enterobacteriaceae in individual pigs on a farm positive for CTX-M-14-producing Escherichia coli. Fecal samples were collected once around the farrowing time from five sows and four times along the production cycle from two of their respective offspring. Multiple colonies per sample were isolated on cefotaxime-supp...
