Extended-spectrum beta-lactamase-producing Enterobacteriaceae in different environments (humans, food, animal farms and sewage).
TLDR
This widespread occurrence of ESBL-producing Enterobacteriaceae suggests that the community could act as a reservoir and that food could contribute to the spread of these strains.
Antibiotic Resistance Trends in Enteropathogenic Bacteria Isolated in 1985–1987 and 1995–1998 in Barcelona
TLDR
The greater increase in the rate of resistance was observed in Campylobacter jejuni for quinolones and tetracycline and in gastroenteric salmonellae for ampicillin, chloramphenicol, and trimethoprim-sulfamethoxazole and nalidixic acid.
Prospective Multicenter Study of Carbapenemase-Producing Enterobacteriaceae from 83 Hospitals in Spain Reveals High In Vitro Susceptibility to Colistin and Meropenem
TLDR
A wide interregional spread of CPE in Spain was observed, mainly due to a few successful clones of OXA-48-producing K. pneumoniae and ST11 and ST405, and most of the CPE had three or more options for antibiotic treatment.
Novel Complex sul1-Type Integron in Escherichia coli Carrying blaCTX-M-9
TLDR
PCR analysis indicates that integron In60 is present in 33 of 34 nonclonal enterobacterial isolates carrying the putative β-lactamase CTX-M-9.
Cloning and Sequence of the Gene Encoding a Novel Cefotaxime-Hydrolyzing β-Lactamase (CTX-M-9) fromEscherichia coli in Spain
TLDR
A new CTX-M-type β-lactamase has been cloned from a clinical cefotaxime-resistant Escherichia coli strain and the 35 amino acids located between residues Ala-185 and Ala-219 are totally different in both enzymes.
Characterization of plasmids encoding blaESBL and surrounding genes in Spanish clinical isolates of Escherichia coli and Klebsiella pneumoniae.
TLDR
A diversity of the plasmid incompatibility groups that harbour blaESBL genes was observed, except for the blaCTX-M-14 gene, and a high variability was confirmed in the genetic environment of these genes as a result of insertion and deletion events.
Evidence for convergent evolution of CTX-M-14 ESBL in Escherichia coli and its prevalence.
TLDR
A total of 2440 Escherichia coli strains isolated in 2003 at the Hospital de la Santa Creu i Sant Pau were evaluated for the presence of extended-spectrum beta-lactamases, and the CTX-M-14 ESBL in E. coli isolates is the result of the convergence of two different genes.
Prevalence and molecular epidemiology of acquired AmpC β-lactamases and carbapenemases in Enterobacteriaceae isolates from 35 hospitals in Spain
TLDR
A great genetic diversity among pAmpC- producing strains and a close clonal relationship between carbapenemase-producing strains is observed and is not negligible.
