Bacteroides fragilis Group

B. fragilis group is the most prevalent bacteriodaceae isolated. B. fragilis is the most prevalent organism in the B. fragilis group, accounting for 41 to 78 of the isolates of the group. However, it should be remembered that the other members of the group account for the rest of the B. fragilis group isolates. The relative distribution of the different B. fragilis group has important clinical implications in the management of infections involving anaerobic bacteria. This is because of the...
