Cell death and biomass reduction in biofilms of multidrug resistant extended spectrum β-lactamase-producing uropathogenic Escherichia coli isolates by 1,8-cineole
(Public Library of Science, 2020-11)
Escherichia coli is the most frequent agent of urinary tract infections in humans. The emergence of uropathogenic multidrug-resistant (MDR) E. coli strains that produce extended spectrum β-lactamases (ESBL) has created ...
Rapid Detection of Carbapenemase and Extended-Spectrum β-Lactamase Producing Gram-Negative Bacteria Directly from Positive Blood Cultures Using a Novel Protocol
(Antibiotics, 2022)
Background: Early and adequate antibiotic treatment is the cornerstone of improving clinical outcomes in patients with bloodstream infections (BSI). Delays in appropriate antimicrobial therapy have catastrophic consequences ...
New TEM-derived extended-spectrum β-lactamase and its genomic context in plasmids from Salmonella enterica serovar derby isolates from Uruguay
(American Society for Microbiology, 2006-02)
A small (8.2-kb) ColE1 plasmid encoding TEM-144 (a new β-lactamase with a ceftazidimase profile) was sequenced by a gene-walking strategy. The blaTEM allele was carried on a Tn2 element, disrupting a Rom protein gene. ...
Propiedades microbiológicas, clasificación y relación estructura-actividad de cefalosporinas e importancia de las cefalosporinas de cuarta generación
(Sociedad Chilena de Infectología, 2001)
CTX-M-producing Klebsiella spp. in a Brazilian hospital: what has changed in 6 years?
(ELSEVIER SCIENCE INC, 2010)
CTX-M-encoding genes from Klebsiella spp. strains isolated in 2000 and 2006 were characterized as well as their genetic environment. CTX-M-2 variants were predominant in Klebsiella pneumoniae strains, which showed a greater ...
Extended-spectrum beta-lactamase-producing Enterobacteriaceae in cell phones of health care workers from Peruvian pediatric and neonatal intensive care units
(Elsevier, 2016)
BACKGROUND: Health care workers (HCWs) use their mobile phones during working hours or medical care. There is evidence that the instruments are colonized with pathogenic microorganisms. Here, we describe levels of ...
Genomic analysis of bifunctional Class C-Class D β-lactamases in environmental bacteria
(Fundação Oswaldo Cruz. Instituto Oswaldo Cruz, 2018)
High Prevalence of blaCTX-Min Fecal Commensal Escherichia coli from Healthy Children
(Korean Society of Infectious Diseases, 2022)
Background: Antibiotic-resistant Escherichia coli can colonize the intestinal tract of healthy children, causing concern when antibiotic resistance is related to the presence of transferable mechanisms, such as extended-spectrum ...
Emergence and dominance of CTX-M-15 extended spectrum beta-lactamase among Escherichia coli isolates from children
(Mary Ann Liebert Inc, 2011-04)
Of forty-seven extended-spectrum cephalosporin-resistant Escherichia coli isolates, collected from children at the Children’s Hospital in 2006 (Tunis, Tunisia), we analyzed 32 isolates that were genotypically different by ...
