Cronobacter sakazakii F37/50

Cronobacter sakazakii F37/50 is a Gram-negative, rod-shaped bacterium that exhibits a unique arrangement of cells, typically found as singles or in pairs. This organism is classified as an anaerobe, indicating that it does not require oxygen for growth. It is non-motile, despite the presence of flagella, suggesting that its movement may be limited or absent in natural environments. The optimal growth temperature for Cronobacter sakazakii F37/50 is 37°C, placing it within the mesophilic temperature range, which is conducive to growth in a variety of environments, including those found in food products. This bacterium has been identified with four distinct replicons, which may contribute to its genetic diversity and adaptability. In terms of its ecological role, Cronobacter sakazakii F37/50 is free-living, meaning it can exist independently in various habitats without necessarily relying on a host organism. This trait may facilitate its survival and proliferation in diverse environments, potentially including food sources. The combination of these traits—its Gram-negative status, anaerobic nature, mesophilic growth, and free-living capability—highlights the adaptability of Cronobacter sakazakii F37/50. Understanding these characteristics is crucial for assessing its ecological impact, particularly in food safety contexts, as this bacterium has been associated with infections in vulnerable populations.
