Background |
Gram-negative bloodstream infections are an important cause of neonatal mortality. In October 2009, we investigated a Klebsiella spp outbreak in a neonatal intensive care unit in Guatemala.
Methods |
Probable cases were defined as a Klebsiella spp isolated from blood in neonates aged <28 days in the neonatal intensive care unit between October 1 and November 10, 2009; confirmed cases were identified as Klebsiella pneumoniae. Clinical data were abstracted from medical charts. K pneumoniae isolates were genotyped by pulsed-field gel electrophoresis (PFGE) and tested for antimicrobial susceptibility. Infection control practices were inspected.
Results |
There were 14 confirmed cases. The median age at onset of infection was 3 days (range, 2-8 days). Nine patients died (64%). K pneumoniae isolates were resistant to multiple antimicrobials. PFGE revealed 2 distinct clusters. Breaches in infection control procedures included inappropriate intravenous solution use and inadequate hand hygiene and contact precautions.
Conclusions |
We report a K pneumoniae outbreak with high neonatal mortality in Guatemala. PFGE clustering suggested a common source possibly related to reuse of a single-use intravenous medication or solution. The risk for K pneumoniae bloodstream infections in neonates in low-resource settings where sharing of solutions is common needs to be emphasized.
