Eikenella corrodens is opportunistic, but it is most noted for causing which type of infections?

• A. Abscesses of the oral cavity
• B. Pneumonia
• C. Postsurgical wound infections
• D. Urinary tract infections

Answer: (A)

Eikenella corrodens is part of the normal oral flora and behaves as an opportunistic pathogen in the mouth. Because it resides in the oral cavity, it is most commonly involved in infections in that region, particularly abscesses around teeth and in surrounding oral tissues. Dental disease or trauma that disrupts mucosal barriers allows this organism to participate in polymicrobial infections, leading to oral abscess formation. While it can cause other infections in certain settings (like respiratory or wound infections), its hallmark association is with abscesses of the oral cavity.
