Identity of Bacteroides isolates and previously named Bacteroides spp in clinical specimens of animal origin

Jang, S.S. | Hirsh, D.C.

During the years 1984 through 1987, 2,574 isolates of obligately anaerobic bacteria were isolated from samples submitted for analysis. The most common anaerobic isolates were members of the genus Bacteroides, representing 44.6% of the isolates. Of these, the most commonly isolated identifiable microorganisms were bile-resistant and nonpigmented, belonging to the B fragilis group of Bacteroides. Importantly, obvious predilections for any one species or group of Bacteroides were not apparent for animal or site (condition), except that the proportion of isolates belonging to the nonpigmented, bile-resistant group obtained from the respiratory tract was significantly (P < 0.005) higher than that not belonging to this group. On the other hand, the proportion of isolates of the nonpigmented, bile-resistant group obtained from abscesses was significantly lower than that not belonging to this group.
