CSF: Cronobacter sakazakii – Shipped May 10, 2021
A simulated CSF sample collected from a 9-day-old female in neonatal intensive care unit (NICU) was sent to category A laboratories.
Participants were expected to identify Cronobacter sakazakii.
MAIN EDUCATIONAL POINTS from M211-5
- Cronobacter sakazakii is an important cause of neonatal meningitis.
- Cronobacter spp. are difficult to accurately speciate, even with MALDI-TOF; laboratories should consider reporting as Cronobacter sp. to avoid misidentification.
- Despite being closely related to Enterobacter, Cronobacter spp. do not have an easily inducible AmpC gene, and should not be reported as an intrinsic AmpC producer.
