Cronobacter sakazakii strain ATCC 29544

Cronobacter sakazakii strain ATCC 29544 is a Gram-negative, rod-shaped bacterium that is classified as an anaerobe, indicating its capacity to thrive in environments devoid of oxygen. This strain is characterized by its non-motility and presence of flagella. It has been identified as a free-living organism, typically found in a host-associated habitat, and is mesophilic with an optimal growth temperature of 37°C. The strain has a complex genomic structure with four replicons, and it has been documented to inhabit various hosts, including Homo sapiens, Viridiplantae, Amphibia, Gastrotheca, and Cucumis sativus. Notably, this strain is recognized for its pathogenic potential in humans, linked to serious health issues such as meningitis, sepsis, septicemia, and necrotizing enterocolitis (NEC). It can also cause mild diseases and has been associated with brain abscesses or lesions. The ecological role of Cronobacter sakazakii strain ATCC 29544 is significant, as its ability to inhabit a variety of hosts suggests a versatile adaptability to different environmental conditions. This adaptability could play a critical role in its transmission dynamics and pathogenicity, particularly in vulnerable populations such as infants and immunocompromised individuals. Understanding the biology and ecology of this strain helps elucidate its impact on health and disease.
