“…The organism partieipates in severe polymicrobial infections in usually sterile body sites, including abseesses of the brain, peritoneal, abdominal and pelvic regions (6,27,31,56), septicemias (27), infected epidermal eysts (7), human bite wounds (18), obstetric and gynecological infections (4), ear infections (4), sinus infections (4), vertebral osteomyelitis (34), and hematogenotis prosthetic joint infections (3,44). In the oral cavity, P. micros has been associated with endodontic abscesses (9,55,57), periodontal abscesses (33), pedtonsillar abscesses (31), mandibular osteomyelitis (12), acute suppurative parotitis (2), fascial plane infections of the head and neck region (12,22,27,38), and osseointegrated dental implants failing due to microbial infection (\). P. micros also has been implicated in the pathogenesis of human periodontitis (14,28,29,36,48,49,57); however, many aspects of its periodontopathic potential remain to be elucidated.…”
