Gram-negative facultatively anaerobic coccobacillio Normal flora in the mouth found in plaque biofilms, saliva and mucosa o Causes dentoalveolar infections, acute sialadenitis (salivary gland infection), infective endocarditis.
Gram-negative microaerophilic or capnophilic (CO2 dependent) coccobacilli- fimbria, many virulence factors - in perio pockets; implicate in aggressive Perio disease (localized & general) - copathogen w cervicofacial Actinomyces
Gram-negative facultatively anaerobic coccobacilli (formerly Bacteriodes)- Plaque biofilms in both healthy & periodontitis ppl
· carbon dioxide-dependent, Gram-negative rodso Found in plaque, mucosal surfaces, saliva o Infections in immunocompromised, destructive periodontal disease o Some strains produce IgA protease.
· Gram-negative anaerobic pleomorphic rods, non-motile; degrades collageno Can be normal flora or significant problem in PD o Gingival crevice and subgingival plaque in small no.s o Ass. w chronic periodontitis and dentoalveolar abscess.
Gram-negative pleomorphic anaerobic rods,o May be part of normal flora. o Also found in periodontal pockets, dental plaque, chronic periodontitis and dentoalveolar abscess.
