Abstract

The most common etiologic agents of neonatal osteomyelitis in the last decades were Staphylococcus aureus, Group B streptococcus, and E. coli, but Klebsiella pneumoniae as a cause of neonatal osteomyelitis appears to be rare. Klebsiella pneumoniae is one of the most important organisms associated with hospital acquired infections in the neonate and outbreaks with multiresistant strains have been reported from neonatal intensive care units around the world. These multiresistant Klebsiella pneumoniae have been shown to produce tranferable plasmid mediated beta-lactamases that are able to hydrolyze oxyimmino- beta-lactamas and these confer resistance to the third generation cephalosporin and named extended spectrum beta-lactamase producing Klebsiella pneumoniae. We experienced two cases of neonatal osteomyelitis due to extended spectrum lactamase producing Klebsiella pneumoniae in our neonatal intensive care unit during the same period. To our knowledge this represents the first documented neonatal osteomyelitise to extended spectrum beta-lactamase producing Klebsiellae pneumoniae in Korea.
