Lactococcus lactis strain C2D

Lactococcus lactis strain C2D is a Gram-positive, cocci-shaped bacterium that typically forms chains. It is categorized as a facultative anaerobe, allowing it to thrive in both the presence and absence of oxygen. With an optimal growth temperature of 40°C, it falls within the mesophilic temperature range. This strain is non-motile and does not possess flagella, which aligns with its free-living biotic relationship. Lactococcus lactis strain C2D has been identified in multiple habitats and has a diverse range of hosts, including Homo sapiens (humans), Bos taurus (cattle), various metazoans, and plants such as Medicago sativa. This strain has been associated with several health conditions, including endocarditis, peritonitis, intra-abdominal infections, and mastitis. Despite its associations with these health issues, it is classified as non-pathogenic in humans. The strain has a single replicon and one membrane, indicating a relatively simple cellular structure. Its non-sporulating nature suggests that it does not form spores to withstand adverse conditions, relying instead on its facultative anaerobic metabolism for survival and reproduction. The presence of Lactococcus lactis strain C2D in various hosts and its association with certain health effects highlight its ecological relevance and potential impact on both human and animal health. Understanding its role in different environments can provide insights into its interactions with various hosts and the microbial communities they inhabit.
