Which bacteria are found in oral infections like pericoronitis?

• A. Mycobacterium tuberculosis
• B. Escherichia coli
• C. Fusobacterium, Strep milleri, Peptostreptococcus
• D. Clostridium tetani

Answer: (C)

The presence of Fusobacterium, Strep milleri, and Peptostreptococcus in oral infections like pericoronitis is significant due to their roles in the polymicrobial nature of these infections. Fusobacterium species are anaerobic bacteria that are commonly found in the oral cavity and are often involved in periodontal diseases and pericoronitis. They contribute to the inflammation and tissue destruction associated with these conditions. Streptococcus milleri, part of a group of viridans streptococci, is known to be part of the normal flora of the mouth and can become pathogenic in cases of compromise, leading to abscess formation and spreading infections. Peptostreptococcus is an anaerobic bacterium that is also prevalent in the oral cavity. Its presence is typically associated with mixed infections in soft tissues, including those seen in pericoronitis. Together, these bacterial species contribute to the infectious process in pericoronitis due to their ability to thrive in the anaerobic environment often found around partially erupted teeth, leading to inflammation and potential systemic effects if left untreated. Recognizing this specific bacterial flora is essential for appropriate management and antibiotic selection in the treatment of oral infections.
