The objective of the present study was to evaluate the prevalence of intestinal colonization with extended-spectrum β-lactamase (ESBL)-producing Enterobacteriaceae (ESBL-E) and carbapenemases-producing Enterobacteriaceae (CPE) in non-selected hospitalized and non-hospitalized patients from the same geographic area of Madrid. Among the 501 patients enrolled, 43 (8.6%) carried ESBL-E and 8 (1.6%) patients exhibited CPE. The main intestinal colonizer among ESBL-E was CTX-M-producing Escherichia coli isolates in both settings (community and hospital)...

The aim of this study was to determine whether the route of extended-spectrum β-lactamase (ESBL) transmission to hospitalized newborns was from their mothers during delivery. Neonatal intensive care unit (NICU) hospitalized newborns were sampled for ESBL presence by stool cultures on the first and fourth days of life. Mothers of ESBL-positive newborns were sampled for possible correlation detection. Bacteria isolates were molecularly identified and susceptibility tests for antibiotic agents were performed...

In a clinical setting it seems to be normal these days that a relevant proportion or even the majority of different bacterial species has already one or more acquired antibiotic resistances. Unfortunately, the overuse of antibiotics for livestock breeding and medicine has also altered the wild-type resistance profiles of many bacterial species in different environmental settings. As a matter of fact, getting in contact with resistant bacteria is no longer restricted to hospitals. Beside food and food production, the aquatic environment might also play an important role as reservoir and carrier...

OBJECTIVES: Community carriage of ESBL-producing Escherichia coli (EPE) is common worldwide and there is a need to understand the connection between carriage and infection. We compared the molecular characteristics of EPE among Swedish community carriers with those of EPE causing invasive infections. METHODS: We collected 2134 faecal samples from randomly selected Swedish inhabitants and examined them for the presence of EPE. All participating volunteers answered a questionnaire about putative risk factors for EPE carriage...

We aimed to investigate the prevalence of extended-spectrum β-lactamases (ESBL)-producing Escherichia coli (E. coli) in Beijing Tongren hospital and find the relationship between colonization and infection. The clinical data of 650 inpatients included between March 2012 and July 2012 were retrospectively reviewed. The prevalence of ESBL-producing E. coli among inpatients was 25.7% (167/650), with the highest of 50.0% in rheumatology ward and lowest of 10.0% in intensive care unit. Hospital stay more than 2 years, usage of antibiotics less than 3 months, and use of glucocorticoids or immunosuppressive were found to be significantly associated with ESBL carriage (P < 0...

INTRODUCTION: Extended-spectrum beta-lactamase-producing Enterobacteriaceae (ESBL-PE) infections are a growing threat to children, and the treatment of these infections becomes more and more challenging. A huge reservoir for ESBLs in the community is the fecal flora of children. This study investigates the rectal colonization, associated risk factors, antimicrobial susceptibility, and molecular characterization of ESBL-PE in Lebanese community infants. METHODOLOGY: A total of 117 rectal swabs were taken from healthy infants between 1 and 12 months of age...

Antibiotic resistance is considered a major threat to healthcare. The Dutch government recently announced additional measures to contain this threat, one of these being the creation of regional care networks dedicated to control antibiotic resistance. Among the anticipated activities of these networks is quantifying the prevalence of antibiotic resistance in nursing homes, through regular point-prevalence surveillance studies. There is a broadly felt belief that nursing homes might be a 'mer à boire' of antibiotic resistance...

Children may be at higher risk for carriage of antimicrobial-resistant bacteria because of higher usage of antimicrobials. They also have higher rates of Shiga toxin-producing Escherichia coli (STEC) infections than other population groups. Some infections, particularly in children, are asymptomatic, but still lead to the excretion of large numbers of bacteria and viruses that may cause clinical disease in other individuals. That is one reason why, in Lower Saxony as in other German federal states - asymptomatic carriers of STEC are excluded from nurseries and schools until three consecutive stool samples test negative in order to prevent secondary cases...

Four-hundred-fifty-eight patients were prospectively included at hospital admission and screened for ESBL-E. coli carriage in 2007 and 2010-12. A 4-fold increase in ESBL carriage (3% to 12%), a 5-fold increase in numbers of community patients among ESBL-carriers and a higher number of multiple ESBL-strains was found in 2010-12. ESBL-E. coli represented the dominant E. coli strain (relative abundance>50%) in 10/32 (31%) ESBL-carriers. This represents a major threat in terms of infectious risk and dissemination...

BACKGROUND: Extended-spectrum cephalosporin-resistant Enterobacteriaceae (ESCRE) are an increasing healthcare problem in both human and veterinary medicine. The spread of ESCRE is complex with multiple reservoirs and different transmission routes. The aim of this study was to investigate if ESCRE carriage in dogs is more prevalent in households with a known human carrier, compared to households where humans are known to be negative for ESCRE. Identical ESCRE strains in humans and dogs of the same household would suggest a possible spread between humans and dogs...

The incidence of urinary tract infections caused by extended-spectrum β-lactamase (ESBL)-producing pathogens is increasing. These infections are associated with a long hospital stay in patients undergoing urological procedures. We aimed to demonstrate that significant intraprostatic diffusion of ertapenem is achieved after a single preoperative administration. A referred sample of 19 patients requiring surgery for benign prostatic hyperplasia was prospectively included. Patients received a 1 g intravenous (i...
