AIM OF THE STUDY: Extended spectrum beta lactamase (ESBL) producing bacteria are resistant to most beta-lactam antibiotics including third-generation cephalosporins, quinolones and aminoglycosides. This resistance is plasmid-borne and can spread between species. Management of ESBL is challenging in children with recurrent urinary tract infections (UTIs) and complex urological abnormalities. We aim to quantify the risk in children and specifically in urological patients. METHODS: Retrospective review of a microbiology database (April 2014 to November 2015)...

We characterize the epidemiology of pediatric bloodstream infections (BSIs) in Switzerland. We analyzed pathogen distribution and resistance patterns in monomicrobial and polymicrobial BSIs in children from 2008 to 2014 using data from the Swiss antibiotic resistance centre (ANRESIS). A confirmatory statistical analysis was performed comparing pathogens and resistance across 20 acute care hospitals. We identified 3,067 bacteremia episodes, of which 1,823 (59 %) were considered true BSI episodes. Overall, S...

PURPOSE OF REVIEW: In the era of increasing antibiotic resistance worldwide, this review highlights the advantages of revival of old antibiotics for treatment of uncomplicated urinary tract infections (uUTIs). RECENT FINDINGS: Recent studies have shown that these four oral old antibiotics, fosfomycin trometamol, nitrofurantoin, nitroxoline and pivmecillinam, show no increasing antibiotic resistance against uropathogens causing uUTI, are still effective for the treatment of uUTI and exhibit only minimal or no collateral damage as compared with fluoroquinolones or third-generation cephalosporines...

Antimicrobial usage in food animals has a direct impact on human health, and approximately 80% of the antibiotics prescribed in the dairy industry are used to treat bovine mastitis. Here we provide a longitudinal description of the changes in the microbiome of milk that are associated with mastitis and antimicrobial therapy. Next-generation sequencing, 16 S rRNA gene quantitative real-time PCR, and aerobic culturing were applied to assess the effect of disease and antibiotic therapy on the milk microbiome...

BACKGROUND: Whereas many antibiotics increase risk of Clostridium difficile infection through dysbiosis, epidemic C difficile ribotypes characterised by multidrug resistance might depend on antibiotic selection pressures arising from population use of specific drugs. We examined the effect of a national antibiotic stewardship intervention limiting the use of 4C antibiotics (fluoroquinolones, clindamycin, co-amoxiclav, and cephalosporins) and other infection prevention and control strategies on the clinical and molecular epidemiology of C difficile infections in northeast Scotland...

France has remained among the top five European countries for ambulatory antibiotic consumption since such monitoring began in 1998. Young children are major antibiotic consumers, in spite of the viral origin of most infections in this population. Recommendations were updated in 2011 to limit prescriptions. In order to assess their impact, diagnoses and prescriptions were compared in a population of children attending daycare centres in southeastern France in 2008 and 2012. Trends in the reimbursement of paediatric antibiotic prescriptions by the national health insurance (NHI) for the whole area were also studied...

OBJECTIVES: Drug immunosuppression, traditionally used to minimize autoimmune developments after liver, kidney, heart, and lung transplant, and which requires high doses of corticosteroids, creates favorable conditions for the development of various infectious processes and the existence of pathogens, which can be activated after transplant. This study aimed to investigate the bacterial pathogens in patients before living-donor kidney transplant. MATERIALS AND METHODS: We prospectively investigated 117 clinical samples of 33 patients who were seen during 2015 at the National Scientific Research Center (Astana, Kazakhstan) before living-donor kidney transplant...

β-lactams are antibiotic molecules able to inhibit cell wall biosynthesis. Among other mechanisms, resistance in Gram-negative bacteria is mostly associated with production of β-lactamase enzymes able to bind and hydrolyze the β-lactam ring. Extended-spectrum β-lactamases extend this ability also to third- and fourth-generation cephalosporins, as well as to carbapenems and monobactams. Vibrio cholerae is the causative agent of epidemic cholera and a public health burden for developing countries like Bangladesh...

INTRODUCTION: Resistance to common antibiotics is a matter of grave concern in treating infections in hospital settings especially in Intensive Care Units (ICUs). One of the most commonly used and effective group of antibiotics, cephalosporins, exhibit resistance due to production of Extended Spectrum Beta- Lactamases (ESBLs). The prevalence of ESBL producing Escherichia coli (E.coli) has increased throughout the world and is a major cause of treatment failure in ICUs. As per our knowledge studies were not available on the prevalence of ESBL producing E...

This study provides a contemporary epidemiology of aspirates taken during surgery from the abdominal cavity among patients with bacterial peritonitis to identify the isolates and study their sensitivity to antibiotics. Our bacteriology investigations included isolation of poor cultures, and detection of microbes was conducted using a rapid identification system (API20E, API Staph, API Strep, API Ana, BioMerieux). Rapid tests for detection of oxidase and catalase activity were also used. Susceptibility of microorganisms to antibiotics was defined by the disc-diffusion method using standard discs (EUCAST guidelines 2015) according to Clinical Laboratory Standard Institute (CLSI) protocols (ATB strips: ATB G, ATB Staph, ATBANA, ATBPse, ATBStrep...

OBJECTIVES: Reduced susceptibility to penicillin G in Neisseria meningitidis is mainly due to alterations in PBP2 encoded by the penA gene. However, this phenotype was not associated with reduced susceptibility to third-generation cephalosporins (C3Gs). We aimed to study the emergence of meningococci with reduced susceptibility to C3Gs (MIC >0.06 mg/L) in France since 2012. METHODS: Invasive meningococcal isolates were typed by MLST and penA sequencing and their antibiotic susceptibility was tested...

BACKGROUND: Gram-negative microorganisms are uncommon pathogens responsible for infective endocarditis. Pseudomonas mendocina, a Gram-negative water-borne and soil-borne bacterium, was first reported to cause human infection in 1992. Since then, it has rarely been reported as a human pathogen in the literature. We describe the first case of native valve infective endocarditis due to P. mendocina in the USA. CASE PRESENTATION: A 57-year-old white man presented with bilateral large leg ulcers, fever, and marked leukocytosis...
