Emergency (clonal spread) of methicillin-resistant Staphylococcus aureus (MRSA), extended spectrum (ESBL)--and AmpC beta-lactamase-producing Gram-negative bacteria infections at Pediatric Department, Bosnia and Herzegovina.

Purpose: Aim of this study was to investigate the prevalence of methicillin-resistant Staphylococcus aureus (MRSA), extended-spectrum (ESBL) and plasmid-mediated AmpC beta-lactamase producing Gram-negative bacteria in children.

Methods: Antibiotic susceptibility of MRSA and beta-lactamase producing Gram-negative bacteria was determined by disc diffusion and broth microdilution methods according to CLSI guidelines. Methicillin resistance was confirmed by the presence of mecA gene by PCR.
