“…Most of the outbreaks due to invasive Cronobacter infections among infants reported over the years were attributed to PIF that was either intrinsically or extrinsically contaminated with C. sakazakii [ 37 ]. Furthermore, there are several reports of infants being infected through contaminated expressed breast milk and cross-contamination from improperly sanitised breast milk pumps [ 34 , 38 , 39 ]. Premature infants, low-birth-weight neonates and infants with underlying medical conditions are at the highest risk for developing severe Cronobacter infections.…”

“…Studies revealed that healthy adults are considerably less susceptible to infection with Cronobacter species [ 41 ]. However, immunocompromised adults and the elderly with aged above 80 years old could be susceptible to the bacterium [ 39 , 42 ]. Additionally, the risk of Cronobacter infection in elderly adults who have experienced stroke is high.…”

“…In addition, genome sequencing highlighted potential markers responsible for virulence in Cronobacter species [ 39 , 140 ]. Virulence factors contributing to Cronobacter pathogenicity consists of genes that function in both adhesion and invasion [ 40 ].…”

The powdered formula market is large and growing, with sales and manufacturing increasing by 120% between 2012 and 2021. With this growing market, there must come an increasing emphasis on maintaining a high standard of hygiene to ensure a safe product. In particular, Cronobacter species pose a risk to public health through their potential to cause severe illness in susceptible infants who consume contaminated powdered infant formula (PIF). Assessment of this risk is dependent on determining prevalence in PIF-producing factories, which can be challenging to measure with the heterogeneity observed in the design of built process facilities. There is also a potential risk of bacterial growth occurring during rehydration, given the observed persistence of Cronobacter in desiccated conditions. In addition, novel detection methods are emerging to effectively track and monitor Cronobacter species across the food chain. This review will explore the different vehicles that lead to Cronobacter species’ environmental persistence in the food production environment, as well as their pathogenicity, detection methods and the regulatory framework surrounding PIF manufacturing that ensures a safe product for the global consumer.

Diketopiperazines as Cross-Communication Quorum-Sensing Signals between Cronobacter sakazakii and Bacillus cereus

et al. 2017

Herein, we reveal a second quorum-sensing system produced by Cronobacter sakazakii. A cyclo(l-Pro–l-Leu) diketopiperazine, detected in pure and mixed cultures of C. sakazakii and Bacillus cereus explains the coexistence of both in the same industrial environments. The molecule was identified by gas chromatography–mass spectrometry (GC–MS), 1H, and 13C NMR, including 2D NMR (correlation spectroscopy, heteronuclear multiple bond correlation, and heteronuclear single quantum correlation), and the absolute configuration was compared with that of four synthetic standards produced by solid phase peptide synthesis using a chiral column on a GC–flame ionization detection. This article provides a new method to determine the absolute configuration of cyclo(Pro–Leu) diketopiperazine replacing the joint use of 1H NMR and Marfey’s method.
