ID#:15233
Description:This photomicrograph of an unknown sample revealed the presence of a mixed infection, which involved Gram-positive Peptostreptococcus anaerobius and P. asaccharolyticus (formerly Peptococcus asaccharolyticus), and Gram-negative Prevotella melaninogenica (formerly Bacteroides melaninogenicus), anaerobic bacteria.
All three of these anaerobes are normally found in the human gastrointestinal, urinary tract, and vaginal cavity. Prevotella melaninogenica is a normal floral inhabitant of the human oral and vaginal cavities, and has been recovered from anaerobic infections involving the respiratory tract, brain abscesses, urinary tract infections, to name a few. Peptostreptococcus anaerobius, P. asaccharolyticus, though commensal organisms, can in times of immunosuppression, become pathogenic, thereby, harming their human host.
