Abstract
Introduction: Nosocomial urinary tract infections are one of the most common hospital acquired infections and often due to multi-drug resistant bacteria. Control of spread is still priority measure of public health. Objective: To describe an outbreak caused by an extended spectrum β-lactamase Klebsiella pneumoniae and research of its hospital reservoir. Patients and methods: Over 12 days period, extended spectrum β-lactamase Klebsiella pneumoniae was isolated from 5 in-patients with urinary tract infection. General warning was given and outbreak investigation was conducted Results: The five strains had the same antibiotype characterized by colistin, amikacin, fosfomycin and imipenem sensibility. Investigation has shown index case and the absence of identified environmental reservoir suggests that transmission was effective by hands. Eradication of epidemic strain was obtained by geographical and technical isolation and amelioration of hygiene conditions. Conclusion: Swift identification of an outbreak by phenotypical characterization of isolated strains allowed the control of this outbreak.
