Cronobacter sakazakii, formerly known as Enterobacter sakazakii, is a foodborne pathogen that has drawn the attention of the scientific community for the last 50 years. This organism was first characterized in 1929 as a ‘yellow-pigmented coliform’ and was discovered to be the causative agent of septicemia in infants.

E. sakazakii is considered to be an opportunistic pathogen, implicated in food borne diseases causing meningitis or enteritis especially in neonates and infants. Cultural standard identification procedures for E. sakazakii include the observation of yellow pigmentation of colonies and a positive glucosidase activity. Up to now, only one PCR system based on a single available 16S rRNA gene

The ability of the bacterium to form biofilms on abiotic surfaces raises the possibility that infections may occur following cross-contamination of freshly prepared infant formula upon contact with soiled surfaces in hospitals, day-care centers and food service kitchens. E. sakazakii species includes a strain which was originally isolated from dried milk in 1960. Therefore, E. sakazakii has been present in dried milk products for many decades. Muytjens et al. (1988) found 14% of 141 PIF samples contained E. sakazakii. In total E. sakazakii was cultured from unused infant formula products from 13 countries. source of E. sakazakii infection.

E. sakazakii was defined as a species in 1980 by JJ Farmer III et al. DNA-DNA hybridization showed that E. sakazakii was 53–54% related to species in two different genera, Enterobacter and Citrobacter. E. sakazakii is a motile, peritrichous, Gram-negative rod that was previously referred to as a ‘yellow-pigmented Enterobacter cloacae ’. E. sakazakii is a recently identified foodborne pathogen that has been implicated most frequently in causing illness in neonates and children from 3 days to 4 years of age. Enterobacter sakazakii, a gram-negative bacillus, is a rare cause of bloodstream and central nervous system infections (1–8). The organism has also been associated with necrotizing enterocolitis; however, it has not been firmly established as a causative agent (8–10).

When the species was defined in 1980, 15 biogroups were described and it was suggested that these could represent multiple species. 3.2 Review of cases of E. sakazakii infections 13 3.3.

E. sakazakii was reclassified into a new genus, Cronobacter, comprising five species including Cronobacter sakazakii gen. nov., Cronobacter malonaticus sp. nov., Cronobacter turicensis sp. nov

2010-08-20 · E. sakazakii is a Gram negative, rod shaped bacterium measuring approximately between 3 μm by 1μm in size and has been found to be peritrichous or highly flagellated, thus being motile. It has historically been describe since as early as 1929 when it was characterized by producing a yellow culture and causing septicemia in infant(s). Cronobacter sakazakii, which before 2007 was named Enterobacter sakazakii, is an opportunistic Gram-negative, rod-shaped, pathogenic bacterium that can live in very dry places. The majority of Cronobacter sakazakii cases are adults but low-birth-weight preterm neonatal and older infants are highest at risk.

It also has been isolated from household vacuum cleaner bags and from the guts of the stable fly, Stomoxys calcitrans , and the Mexican fruit fly, Anastrpha ludens ( 29 – 31 ). E. sakazakii has caused disease in all age groups. Statistics indicate that infants, in particular pre-term, underweight or immunocompromised infants, are at greatest risk.
