Extended-spectrum cephalosporins (ESCs) are critically important antibiotics for humans and their use in animals poses a potential threat for public health. Chicken represents an increasing part of the human diet and has also been regarded as a source of ESC-resistant Enterobacteriaceae because of the worldwide off-label use of ceftiofur, a broad-spectrum cephalosporin. Thus, numerous studies pointed out chicken as a reservoir of ESBL/pAmpC genes, plasmids and/or clones at risk for humans. In France, late 2011, strong political pressure led to a drastic reduction of ceftiofur use and all other antibiotics in chicken production...

Recommendations for the treatment of lower non-catheter-related urinary tract infection (UTI) in men are rarely evidence-based. Their management requires the localization of the site of infection, whether it be the urethra, bladder or prostate, and includes antibiotic therapy and in most cases urological assessment. They are often associated with urinary tract procedures or anatomical or functional abnormalities. Nearly 80 % of male UTIs are caused by Enterobacteriaceae. The prevalence of broad-spectrum beta-lactamase-producing strains (ESBL) and quinolone-resistant strains is increasing...

Optimizing and standardizing susceptibility testing for the polymyxins have become a pressing issue given the rise multidrug-resistant Gram-negative bacilli. Recently both CLSI-EUCAST have recommended broth microdilution (BMD) (without polysorbate) as the reference method for polymyxin susceptibility testing. In this issue, Chew et al. (doi: https://doi.org/10.1128JCM.00268-17.) compare the performance of three commercial BMD panels and the Etest to reference BMD for polymyxin B and colistin, on 76 Enterobacteriaceae isolates (21 mcr-1 positive)...

CONTEXT: The significant global upsurge in antimicrobial resistance, particularly among Enterobacteriaceae, represents a serious threat to health care systems. The implications for urologic practice are of particular concern. OBJECTIVE: To review trends in antibiotic resistance in urologic practice. EVIDENCE ACQUISITION: We report current European trends of resistance in Gram-negative uropathogens. EVIDENCE SYNTHESIS: In addition to β-lactam resistance, Gram-negative pathogens are often resistant to multiple drug classes, including aminoglycosides, fluoroquinolones, and carbapenems, commonly used to treat urologic infections...

Objective In recent years, infection caused by extended-spectrum beta-lactamase (ESBL)-producing organisms has become an important issue. However, comparative studies of the bacteremia caused by ESBL Enterobacteriaceae and non-ESBL Enterobacteriaceae are extremely rare in Japan. This study aimed to assess the risk factors and prognosis of patients with bacteremia due to ESBL Escherichia coli (E. coli). Methods The medical records of 31 patients with ESBL E. coli bacteremia and 98 patients with non-ESBL E. coli bacteremia who had been admitted to Osaka City University Hospital between January 2011 and June 2015 were retrospectively reviewed...

BACKGROUND: The upper half of the human small intestine, known as the jejunum, is the primary site for absorption of nutrient-derived carbohydrates, amino acids, small peptides, and vitamins. In contrast to the colon, which contains 10(11)-10(12) colony forming units of bacteria per ml (CFU/ml), the normal jejunum generally ranges from 10(3) to 10(5) CFU per ml. Because invasive procedures are required to access the jejunum, much less is known about its bacterial microbiota. Bacteria inhabiting the jejunal lumen have been investigated by classical culture techniques, but not by culture-independent metagenomics...

Asymptomatic colonisation of the gastrointestinal tract by carbapenemase-producing Enterobacteriaceae is an important reservoir for transmission, which may precede infection. This retrospective observational case-control study was designed to identify risk factors for developing clinical infection with OXA-48-producing Klebsiella pneumoniae in rectal carriers during hospitalisation. Case patients (n = 76) had carbapenemase-producing K. pneumoniae (CPKP) infection and positive rectal culture for CPKP. Control patients (n = 174) were those with rectal colonisation with CPKP but without CPKP infection...

In patients colonized with extended-spectrum β-lactamase-producing Enterobacteriaceae (ESBL-E), the preference for carbapenems (CRB) over non-CRB antibiotics for empiric therapy of sepsis is questionable from an ecologic perspective and also how well colonization actually predicts an ESBL-E etiology of infection has been poorly investigated. The purpose of this retrospective observational study was to determine the positive predictive value (PPV) of ESBL-E fecal colonization for ESBL-E etiology of sepsis and the impact of empiric therapy on treatment outcome...

Carbapenemase producing Citrobacter freundii (CPCF) infections are still uncommon in European countries. Here we report a molecular study conducted in a tertiary care facility in southern Madrid, Spain, from 2009 to 2014 to investigate the epidemiology of CPCF. The blaIMP-1,blaIMP-2,blaKPC,blaNDM,blaOXA-48,blaVIM-1 and blaVIM-2 genes were screened by PCR. Molecular typing was carried out by Pulsed-field gel electrophoresis analysis (PFGE) and multilocus sequence typing (MLST). Whole genome sequencing (WGS) was performed to characterize the resistome and the mobile genetic elements associated with the carbapenems resistance of CPCF...
