a. an anaerobic, filamentous bacterium that often causes cervicofacial osteomyelitis

b. a beta hemolytic organism that causes a diffuse, rapidly spreading cellulitis

c. a facultative anaerobe that is highly cariogenic and sticks to teeth by synthesis of a dextran

d. a faculative anaerobe that often inhabits the buccal musoca early in a neonates life and can cause bacterial RF

e. a faculative anerobic, rod shaped bacterium that sticks to the teeth and is cariogenic, commonly involved in problems involving dental procedures, trauma to or surgery of the oral cavity, or aspiration

Explanation / Answer

Actinomyces is a rod shaped gram positive bacteria and it is found in oral cavity and root of teeth.it is also cariogenic so the option E is correct I.e.
