Extract
Sir,
Klebsiella pneumoniae is a well-recognized nosocomial pathogen causing blood, urinary tract and respiratory tract infections. Since the early 1990s, extended-spectrum β-lactamase (ESBL)-producing and multiresistant K. pneumoniae isolates have rapidly emerged.1
The European Antimicrobial Resistance Surveillance System (EARSS) is an international network of national surveillance systems that attempts to collect reliable and comparable antimicrobial resistance data on invasive pathogens.2,3 Recently, K. pneumoniae has been included as one of the EARSS indicator organisms.
The goals of this surveillance study were to determine the antibiotic resistance prevalence of K. pneumoniae causing blood infections in Spain and to describe the spread of an SHV-12-producing strain in a Spanish hospital.
The selection of the 35 participating hospitals was done according to EARSS criteria.2,3 All the first blood infections per patient obtained between October 2005 and March 2007 were included. To assess the comparability of susceptibility test results, a quality assurance exercise (UK National External Quality Assessment Scheme) was performed. By definition, patients with community-acquired infections were those who had a positive culture of K. pneumoniae at the time of or within 48 h of hospitalization.
