Key demographic characteristics of patients with bacteriuria due to extended spectrum beta-lactamase (ESBL)-producing Enterobacteriaceae in a multiethnic community, in North West London.

Background: Infections with extended-spectrum beta-lactamase-producing Enterobacteriaceae (ESBLE) are encountered worldwide, particularly in certain regions of the world and in certain ethnic groups. Simple criteria for identification of patients likely to be infected with ESBLE may enable clinicians to select appropriate empirical antibiotics for treatment. The aim of this study was to explore the association between ESBLE bacteriuria and readily available key demographic characteristics (age, gender and ethnicity) in a multiethnic population.

Prevalence of antimicrobial resistance in intestinal flora of patients undergoing prostatic biopsy: implications for prophylaxis and treatment of infections after biopsy.

Objective: To determine the prevalence of antimicrobial resistance in intestinal flora of patients undergoing transrectal ultrasonography (TRUS)-guided prostate biopsies (TGB) and to examine if this information is useful in selecting appropriate antimicrobial agents for prophylaxis and treatment of biopsy-associated infections.

Patients And Methods: In 2007 and 2008, rectal swabs were cultured from patients before undergoing TGB. Antimicrobial sensitivity of coliforms to amikacin, ciprofloxacin and coamoxiclav was determined.
