Individual cell lag time distributions of Cronobacter (Enterobacter sakazakii) and impact of pooling samples on its detection in powdered infant formula.

Cells of six strains of Cronobacter were subjected to dry stress and stored for 2.5 months at ambient temperature. The individual cell lag time distributions of recovered cells were characterized at 25 °C and 37 °C in non-selective broth.

Impact of pooling powdered infant formula samples on bacterial evolution and Cronobacter detection.

Enterobacter sakazakii has been identified as the causative agent of serious neonatal infections, associated with high mortality rates. In most cases, powdered infant formula (PIF) has been identified as the source of infection. Recently, strains commonly referred to as E.
