Streptococcus ilei

Streptococcus ilei is a Gram-positive bacterium characterized by its cocci shape. It is classified as a facultative anaerobe, meaning it can grow in both the presence and absence of oxygen, allowing it to adapt to various environments. Notably, S. ilei possesses flagella, which is atypical for many streptococci, potentially contributing to its motility and ability to colonize different niches. The genetic material of S. ilei is organized into two replicons, which may play a role in its genetic stability and adaptability. The organism is represented in the National Center for Biotechnology Information (NCBI) database with accessions NC_022582.1 and NC_022584.1, indicating its genome sequences are available for further study. The presence of flagella in Streptococcus ilei could imply ecological advantages, such as enhanced mobility in various habitats or the ability to evade host defenses. This trait may facilitate its survival and colonization in diverse environments, including those within animal hosts. Understanding the characteristics of S. ilei, particularly its motility and anaerobic capabilities, can provide insights into its ecological roles and potential interactions within microbial communities.
