Pediococcus acidilactici strain FAM 18969

Pediococcus acidilactici strain FAM 18969 is a Gram-positive, non-motile, cocci-shaped bacterium classified as a chemoheterotroph. This strain is an anaerobe, thriving in environments devoid of oxygen. It has an optimal growth temperature of 30°C and falls within the mesophilic temperature range. The strain is notable for its broad host spectrum, which includes Homo sapiens (humans), Gallus gallus (domestic chickens), Hordeum vulgare (barley), Oryctolagus cuniculus (European rabbits), Raphanus sativus (radishes), and Salvelinus alpinus (arctic char). This diverse range of hosts indicates its ecological versatility and potential for interaction with various biological systems. Pediococcus acidilactici strain FAM 18969 is associated with several health concerns in humans, including endocarditis, sepsis, skin infections, opportunistic infections, Fournier's gangrene, and internal organ infections or abscesses. These associations underline its potential pathogenicity, particularly in immunocompromised individuals. Despite its clinical relevance, this strain does not engage in sporulation, which may influence its survival strategies in different environments. The single replicon structure suggests a streamlined genomic organization, possibly contributing to its adaptability. In summary, the ecological insight into Pediococcus acidilactici strain FAM 18969 highlights its role as both a commensal and a potential pathogen across a variety of hosts. Understanding its interactions within different ecological niches can aid in addressing the health impacts it may cause in humans and other species.
