Cronobacter sakazakii ATCC BAA-894

Cronobacter sakazakii ATCC BAA-894 is a gram-negative, rod-shaped bacterium that thrives in mesophilic conditions, showing a temperature preference of around 30-37°C. As a chemoheterotroph, it relies on organic compounds for energy and carbon, making it adaptable to various environments. This bacterium is classified as a facultative anaerobe, allowing it to grow in the presence or absence of oxygen, although it prefers aerobic conditions. Cronobacter sakazakii is known for its presence in various environments, notably in dried foods such as powdered infant formula and other food products. Its versatility allows it to inhabit not only food sources but also environmental niches like soil and water. The ability to survive desiccation and resist harsh conditions makes it a significant concern for food safety. This pathogen can colonize the gastrointestinal tract, and its implications are particularly severe in neonates and immunocompromised individuals, leading to conditions like meningitis and enteritis. In terms of pathogenicity, Cronobacter sakazakii has been associated with severe infections, especially in infants, where it may cause necrotizing enterocolitis. It can produce biofilms, contributing to its persistence in food-processing environments, complicating efforts at decontamination. Furthermore, this microbe exhibits resistance to multiple antibiotics, raising concerns in clinical settings regarding treatment efficacy. In addition to its health implications, research has demonstrated that Cronobacter sakazakii possesses unique biochemical properties that allow for the production of various enzymes, leading to potential applications in biotechnology. The ongoing study of this bacterium continues to shed light on its role in food safety and human health, making it a subject of great scientific interest.
