Multidrug-resistant (MDR) O25b-ST131 clone of Escherichia coli is well established as a significant cause of extra-intestinal infections worldwide. However, there have been no studies about the prevalence of ST131 and its H30/H30Rx subclones from Iran. The prevalence of ST131 was 29.8% among phylogroups B2, D, and F of E.coli isolates recovered from extra-intestinal infections. Fifty-seven (90.4%) and six (9.6%) of isolates belonged to serogroups O25b and O16 respectively, and exhibited high rates of MDR (98...

Several reasons may explain why measles was not eliminated by 2015 and continues to persist in Europe, including low measles vaccination coverage, low anti-measles herd immunity levels, and the mobility of individuals with measles across Europe. The study assessed the mean measles vaccination coverage in the European Union and the WHO European region with one and two doses of measles vaccine from 1980 to 2015, and the prevalence of vaccine-induced protected individuals and anti-measles herd immunity levels in the WHO European region during 2000-2015...

The purpose of this investigation was to elucidate the impact of prompt intervention for patients whose blood culture results became positive during weekends, as this is not standard care in some countries. A retrospective cohort study was conducted in a tertiary referral hospital. From June 2015, results of positive blood cultures became available during weekends. If infectious disease specialists identified cases of bacteremia on suboptimal antimicrobial coverage, they contacted the primary team for modification of antibiotic treatment...

Noroviruses are a leading cause of epidemic and sporadic cases of acute gastroenteritis worldwide. The rapid diagnosis of norovirus infection is important for prompt infection control measures and may reduce the need for additional diagnostic testing. Here we evaluated the performance of the rapid Xpert Norovirus assay, and assessed the turn-around time (TAT) before and after the implementation of the analysis as a 24/7 service at all the three hospitals in Jönköping County, Sweden. We describe the implementation process which was performed in two steps during 2014...

A rapid microarray assay, Nanosphere Verigene® Gram-negative blood culture test (BC-GN), detects four Gram-negative species, four Gram-negative genera, and six resistance genes directly from positive blood culture samples, shortening the time from Gram stain to pathogen and resistance-gene identification. The purpose of this study was to determine the impact of the BC-GN paired with an antimicrobial stewardship intervention on antimicrobial and clinical outcomes. Patients with Gram-negative bacteremia were compared before (n = 456) and after (n = 421) BC-GN implementation...

Cytomegalovirus (CMV) is the most common viral agent of congenital infections and a leading nongenetic cause of sensorineural hearing loss (SNHL). The host immunologic factors that render a developing foetus prone to intrauterine CMV infection and development of hearing loss are unknown. The aim of this study was to assess the potential associations between the polymorphisms within cytokine and cytokine receptors genes, and the risk of congenital CMV infection, and the hearing outcome. A panel of 11 candidate single nucleotide polymorphisms (SNPs): TNF rs1799964, TNF rs1800629, TNFRSF1A rs4149570, IL1B rs16944, IL1B rs1143634, IL10 rs1800896, IL10RA rs4252279, IL12B rs3212227, CCL2 rs1024611, CCL2 rs13900, CCR5 rs333 was genotyped in 470 infants (72 with confirmed intrauterine CMV infection and 398 uninfected controls), and related to congenital CMV infection, and the outcome...

Although hematological abnormalities have been described among patients with influenza virus infection, little is known about their impact on the outcome of the patients. The aim of this study was to assess the frequency and clinical impact of severe hematological abnormalities in patients with confirmed influenza virus infection. This was an observational retrospective study including all adult patients with diagnosis of influenza virus infection hospitalized from January to May 2016 in our institution. Influenza virus infection was diagnosed by means of rRT-PCR assay performed on respiratory samples...

Even with appropriate clinical management, complicated methicillin-susceptible Staphylococcus aureus (MSSA) catheter-related bacteremia (CRB) is frequent. We investigated the influence of molecular characteristics of MSSA strains on the risk of complicated bacteremia (CB) in MSSA-CRB. A multicenter prospective study was conducted in Spain between 2011 and 2014 on MSSA-CRB. Optimized protocol-guided clinical management was required. CB included endocarditis, septic thrombophlebitis, persistent bacteremia and/or end-organ hematogenous spread...

Daptomycin (DAP) is widely used in the treatment of methicillin-resistant Staphylococcus aureus (MRSA) infection. The emergence of DAP non-susceptible MRSA strains during therapy is a major concern in clinical settings. Recent studies revealed that MRSA spontaneously reverts to a subsequent methicillin-susceptible S. aureus (MSSA) strain. However, it is not clear whether DAP non-susceptible MRSA has the ability to revert to a susceptible strain. We obtained an MRSA strain pair, DAP non-susceptible strain and subsequent DAP susceptible strain, from a patient...

Screening for multidrug-resistant Enterobacteriaceae is performed in many institutions as part of infection control measures. However, the sensitivity of current standard diagnostics is modest. Furthermore, patients are usually screened by rectal swabs (mostly rayon based), which have been shown to be sub-optimal for the recovery of Enterobacteriaceae. Therefore, it is likely that many patients colonised with multidrug-resistant Enterobacteriaceae remain undetected. The present study aimed to analyse if the detection of multidrug-resistant Enterobacteriaceae can be improved when screening with rayon swabs is done in combination with an additional pre-enrichment step...

Up to now, little has been known about the prevalence and clinical relevance of colonisation of asymptomatic pregnant women with methicillin-susceptible Staphylococcus aureus (MSSA), methicillin-resistant S. aureus (MRSA) or extended-spectrum β-lactamase (ESBL)-producing Escherichia coli. In this two-centre cross-sectional study, we evaluated the performance and importance of screening at different times and different locations for colonisation in pregnant women and newborns. Between October 2013 and December 2015, four samples were collected from pregnant women, two from newborns at birth and three from 3-day-old newborns...

Staphylococcus aureus is one of the most common causes of skin and soft tissue infections in health-care and community settings, but transmission of S. aureus in community-based populations is incompletely understood. S. aureus carriage phenotypes (persistent, intermittent, and non-carriers) were determined for households from Starr County, TX. Nasal swabs were collected from a cohort of 901 residents and screened for the presence of S. aureus. Isolated strains were spa-typed and assigned to clonal complexes...

The spread of multi-drug resistant (MDR) Klebsiella pneumoniae strains producing carbapenemases points to a pressing need for new antibacterial agents. To this end, the in-vitro antibacterial activity of a synthetic N-terminal peptide of human lactoferrin, further referred to as hLF1-11, was evaluated against K. pneumoniae strains harboring different carbapenemase genes (i.e. OXA-48, KPC-2, KPC-3, VIM-1), with different susceptibility to colistin and other antibiotics, alone or in combination with conventional antibiotics (gentamicin, tigecycline, rifampicin, clindamycin, and clarithromycin)...
