| Description | Eikenella corrodens is a gram-negative, rod-shaped bacterium that thrives at human body temperature, categorizing it as a mesophile. This microbe is a heterotroph, relying on organic compounds for nutrition, and is classified as a facultative anaerobe, able to grow in both aerobic and anaerobic environments. Eikenella corrodens is part of the normal flora of humans, colonizing various body sites, including the mouth, gastrointestinal tract, and female genital tract, where it plays a role in maintaining microbial balance. The gram-negative nature of Eikenella corrodens indicates that it has a thin peptidoglycan layer and is surrounded by an outer membrane containing lipopolysaccharides, which can contribute to its pathogenic potential. This bacterium's rod-shaped morphology allows it to adapt well to its environments, whether within the biofilms of oral cavities or in deeper tissue infections. As a mesophilic organism, it prefers temperatures around 37°C, which aligns perfectly with the human body temperature, providing ideal conditions for growth. Being a facultative anaerobe, Eikenella corrodens can utilize oxygen when available but also has the flexibility to grow in its absence, showcasing its versatility. Its heterotrophic nature means it metabolizes organic matter, often from the host, contributing to both its symbiotic and pathogenic relationships. Eikenella corrodens is associated with human bite wounds and dental infections, and it can cause serious infections in immunocompromised individuals. Remarkably, it has been recognized for its role in periodontitis and endocarditis, highlighting its significance in both oral health and systemic infections. Interestingly, despite its pathogenic potential, Eikenella corrodens has been noted for its susceptibility to many antibiotics, allowing for effective treatment options in cases of infection. |
