Disease Roles
Bacteroides species Overview
Bacteroides species are Gram-negative, obligate anaerobic bacilli that are a significant component of the human microbiota, commonly found in the oral cavity. They play roles in maintaining ecological balance within biofilms and help break down complex molecules. While generally beneficial, they can become opportunistic pathogens if they translocate to sterile sites. Bacteroides exhibit high levels of antibiotic resistance.
