Bacteroides fragilis

Front 11

These two species of bacteria cause about 80% of anaerobic septicemias, or 8% of all septicemias

Back 11

Bacteroides fragilis and Clostridium perfringens

Front 12

This bacteria is more common in oral infections, and along with spirochetes and other anaerobes, is a serious etiologic agent of periodontal disease; it is also occasionally found in genital infections

Back 12

Prevotella melaninogenicus

Front 13

This bacteria is more difficult to isolate than B. fragilis because they are more sensitive to traces of oxygen

Back 13

Prevotella melaninogenicus

Front 14

This bacteria derives its name from "black pigment", and requires hemin for growth

Back 14

Prevotella melaninogenicus

Front 15

This bacteria is needle-shaped with tapered ends--very thin in contrast to other gram negative rods

Back 15

Fusobacterium

Back 16

Fusobacterium

Front 17

Many strains of this anaerobe /are/ resistant to penicillin

Back 17

Prevotella melaninogenicus
