Enterococcus casseliflavus strain L5-B

Enterococcus casseliflavus strain L5-B is a Gram-positive bacterium primarily found in the intestines. This strain exhibits the morphological characteristics of cocci and has the capability to move due to the presence of flagella. It is classified as a facultative anaerobe, allowing it to thrive in both aerobic and anaerobic environments. The strain has been identified in various hosts, including Homo sapiens (humans), various Metazoa, and multiple insect species such as Lepidoptera and Aves. Specific insect hosts include Spodoptera frugiperda, Spodoptera litura, Manduca sexta, Peridroma saucia, Bombyx mori, Heliothis virescens, Hyles euphorbiae, and Helicoverpa armigera, as well as the cassowary (Casuarius casuarius). This broad host range suggests a versatile ecological role for E. casseliflavus L5-B in different environments. Clinically, E. casseliflavus strain L5-B has been associated with health issues such as bacteremia and liver cyst infections. These health effects underscore the potential pathogenicity of this strain in humans and possibly other hosts. The strain is characterized by having a single replicon, which is essential for its replication and survival. The presence of E. casseliflavus in both human and diverse animal intestines indicates its adaptability and potential significance in microbial ecology, particularly in understanding gut microbiomes and the interactions between host organisms and their microbial inhabitants.
