Hafnia alvei ATCC 51873

Hafnia alvei ATCC 51873 is a Gram-negative, rod-shaped bacterium categorized as a mesophile, thriving optimally at moderate temperatures between 20°C to 45°C. As a chemoheterotroph, it derives energy and carbon from organic compounds, typically engaging in fermentation processes. This microbe is commonly found in a variety of body sites across different species, residing primarily in the intestinal tracts of humans and animals, as well as in environmental niches such as soil and water. The Gram-negative characteristic of Hafnia alvei indicates it has a thin peptidoglycan layer surrounded by an outer membrane, which is composed of lipopolysaccharides. This structure contributes to its ability to evade certain immune responses. The rod shape enhances its mobility and colonization capabilities within various environments, facilitating interactions with other microorganisms and hosts. As a mesophile, Hafnia alvei adapts to the moderate temperatures typical of its native habitats, including the mammalian gut where it plays a role in digestion. Its classification as a chemoheterotroph allows it to utilize diverse organic substrates, such as sugars and amino acids, reflecting its ecological flexibility. Hafnia alvei has been studied for its probiotic potential, with some strains exhibiting beneficial effects on gut health. Moreover, it has garnered attention in clinical microbiology due to its occasional association with opportunistic infections, particularly in immunocompromised individuals. Its resilience and adaptability make it a significant player in microbiome research, emphasizing its role in both health and disease contexts.
