Yersinia aleksiciae Y159, H254-36/86, Y 159

Yersinia aleksiciae Y159, H254-36/86, and Y159 are characterized as gram-negative, chemoheterotrophic bacteria with a rod shape. These organisms are obligate aerobes, meaning they require oxygen for growth. Notably, they have a single replicon and are classified as mesophilic, with an optimal growth temperature of 30°C. In terms of motility, Yersinia aleksiciae possesses flagella; however, it is described as non-motile in practice. This might suggest that while the potential for movement exists due to flagella presence, environmental or physiological factors could limit their mobility. Yersinia aleksiciae has been isolated from various hosts, including Homo sapiens (humans), Sus scrofa (domestic pigs), Mammalia (mammals), and Rangifer tarandus (reindeer), indicating a broad host range. This adaptability may contribute to its ecological versatility. Importantly, Yersinia aleksiciae is classified as non-pathogenic, which sets it apart from many other members of the Yersinia genus known for their pathogenic traits. This characteristic may influence its ecological roles, allowing it to coexist in diverse environments without posing a threat to its hosts. The presence of Yersinia aleksiciae in both humans and animals highlights its potential significance in microbial ecosystems, possibly contributing to nutrient cycling or symbiotic relationships in its various habitats.
