Modelling the epidemiology of Escherichia coli ST131 and the impact of interventions on the community and healthcare centres
(Cambridge University Press, 2016)
ST131 Escherichia coli is an emergent clonal group that has achieved successful worldwide spread through a combination of virulence and antimicrobial resistance. Our aim was to develop a mathematical model, based on ...

Intracellular penetration and activity of gemifloxacin in human polymorphonuclear leukocytes
(American Society for Microbiology, 2000-11-09)
The intracellular penetration and activity of gemifloxacin in human polymorphonuclear leukocytes (PMN) were evaluated. Gemifloxacin reached intracellular concentrations eight times higher than extracellular concentrations. ...

Evaluation of three automated systems for susceptibility testing of enterobacteria containing qnrB, qnrS, and/or aac(6′)-Ib-cr
(American Society for Microbiology, 2011)
The accuracy of the MicroScan WalkAway, BD Phoenix, and Vitek-2 systems for susceptibility testing of quinolones and aminoglycosides against 68 enterobacteria containing qnrB, qnrS, and/or aac(6′)-Ib-cr was evaluated using ...

Disbalancing Envelope Stress Responses as a Strategy for Sensitization of Escherichia coli to Antimicrobial Agents
(Frontiers Media, 2021)
Disbalancing envelope stress responses was investigated as a strategy for sensitization of Escherichia coli to antimicrobial agents. Seventeen isogenic strains were selected from the KEIO collection with deletions in genes ...

Uptake and intracellular activity of an optically active ofloxacin isomer in human neutrophils and tissue culture cells
(American Society for Microbiology, 1990-01-01)
The penetration of an optically active ofloxacin isomer [(-)-ofloxacin] into human neutrophils and different tissue culture cells (HEp-2, McCoy, MDCK, and Vero) was studied and compared with that of ofloxacin by a fluorometric ...

Do specific antimicrobial stewardship interventions have an impact on carbapenem resistance in Gramnegative bacilli? A multicentre quasi-experimental ecological study: time-trend analysis and characterization of carbapenemases
(Oxford University Press, 2021)
Background: Carbapenem-resistant Gram-negative bacilli (CR-GNB) are among the most threatening microorganisms worldwide and carbapenem use facilitates their spread. Antimicrobial stewardship programmes (ASPs) can help to ...

Resistance of Pseudomonas aeruginosa to imipenem induced by eluates from siliconized latex urinary catheters is related to outer membrane protein alterations
(American Society for Microbiology, 1999-02-01)
The activity of imipenem against Pseudomonas aeruginosa HUS-3 decreased by 16 times in the presence of substances eluted from siliconized latex urinary catheters (SLUCs). SLUCs did not inactivate imipenem or increase β- ...

Four main virotypes among extended-spectrum-β-lactamase-producing isolates of Escherichia coli O25b:H4-B2-ST131: bacterial, epidemiological, and clinical characteristics
(American Society for Microbiology, 2013-10)
A total of 1,021 extended-spectrum- -lactamase-producing Escherichia coli (ESBLEC) isolates obtained in 2006 during a Spanish national survey conducted in 44 hospitals were analyzed for the presence of the O25b:H4-B2-ST131 ...

Klebsiella pneumoniae Strains Producing Extended-Spectrum B-Lactamases in Spain: Microbiological and Clinical Features
(American Society for Microbiology, 2011-03)
Extended-spectrum B-lactamases (ESBL) of the CTX-M, SHV, and TEM families were recognized in 76 (67%), 31 (27%), and 6 (5%) isolates, respectively, among 162 ESBL-producing Klebsiella pneumoniae (ESBLKp) strains obtained ...

Clinical characteristics and outcome of bacteraemia caused by Enterobacter cloacae and Klebsiella aerogenes: more similarities than differences
(Elsevier, 2021)
Objectives The genus Enterobacter is a common cause of nosocomial infections. Historically, the most frequent Enterobacter species were those of Enterobacter cloacae complex and Enterobacter aerogenes. In 2019, E. ...
