Interhospital Spread of blaVIM-1- and blaCTX-M-15-Producing K. pneumoniae ST15 on an IncR Plasmid in Southern Spain
(Multidisciplinary Digital Publishing Institute (MDPI), 2023)
In 2014–2015, the main CTX-M-15- and OXA-48-producing clone in our region was ST15. Recently, K. pneumoniae ST15 isolates co-producing VIM-1 and CTX-M-15 were detected in several hospitals. The aim was to study the emergence ...

Effect of Glycerol on Fosfomycin Activity against Escherichia coli
(Multidisciplinary Digital Publishing Institute (MDPI), 2022)
Fosfomycin is an antimicrobial that inhibits the biosynthesis of peptidoglycan by entering the bacteria through two channels (UhpT and GlpT). Glycerol is clinically used as a treatment for elevated intracranial pressure ...

Clinical Features and Outcomes of Streptococcus anginosus Group Infective Endocarditis: A Multicenter Matched Cohort Study
(Oxford University Press, 2021-06)
Background Although Streptococcus anginosus group (SAG) endocarditis is considered a severe disease associated with abscess formation and embolic events, there is limited evidence to support this assumption. Methods We ...

Prospective multicenter study of carbapenemase-producing Enterobacteriaceae from 83 hospitals in Spain reveals high in vitro susceptibility to colistin and meropenem
(American Society for Microbiology, 2015-06-01)
The aim of this study was to determine the impact of carbapenemase-producing Enterobacteriaceae (CPE) in Spain in 2013 by describing the prevalence, dissemination, and geographic distribution of CPE clones, and their ...

Inhibitor-resistant TEM- And OXA-1-producing Escherichia coli isolates resistant to amoxicillin-clavulanate are more clonal and possess lower virulence gene content than susceptible clinical isolates
(American Society for Microbiology, 2014-01-01)
In a previous prospective multicenter study in Spain, we found that OXA-1 and inhibitor-resistant TEM (IRT) β-lactamases constitute the most common plasmid-borne mechanisms of genuine amoxicillin-clavulanate (AMC) resistance ...

Urinary tract physiological conditions promote ciprofloxacin resistance in low-level-quinolone-resistant Escherichia coli
(American Society for Microbiology, 2016-07-01)
Escherichia coli isolates carrying chromosomally encoded low-level-quinolone-resistant (LLQR) determinants are frequently found in urinary tract infections (UTIs). LLQR mutations are considered the first step in the ...

Assessing the Impact of SARS-CoV-2 Lineages and Mutations on Patient Survival
(MDPI, 2022)
Objectives: More than two years into the COVID-19 pandemic, SARS-CoV-2 still remains a global public health problem. Successive waves of infection have produced new SARS-CoV-2 variants with new mutations for which the ...

Reporting antimicrobial susceptibilities and resistance phenotypes in Staphylococcus spp.: a nationwide proficiency study
(Oxford University Press, 2021-02-08)
Objectives To evaluate the proficiency of microbiology laboratories in Spain in antimicrobial susceptibility testing (AST) of Staphylococcus spp. Materials and methods Eight Staphylococcus spp. with different resistance ...
Article
Prevalence and transmission dynamics of Escherichia coli ST131 among contacts of infected community and hospitalized patients
(Elsevier, 2018)
Objectives: The Escherichia coli O25b-associated ST131 clonal group was recently found to be prevalent in our area as a cause of community-acquired urinary tract infections. We evaluated the transmission dynamics and ...

MDR Shigella sonnei in Spain: an ever-evolving emerging threat?
(Oxford University Press, 2022-09-05)
Background Seven CTX-M-27-producing Shigella sonnei strains were isolated at the University Hospital Virgen del Rocío (Seville, Spain) microbiology service from October to November 2021. Objectives To offer extensive ...
