Bacteroides fragilis is a prevalent anaerobic bacterium typically resides in the human vagina. It is known to potentially induce infections under specific conditions. Interestingly, there have been no previous reports of B. fragilis being isolated from t
Bacteroides (B) fragilis is anaerobic bacilli with pale reddish color when stained with gram stain and one of the microflora members of the individual digestive system and female reproductive track. Bacteroides fragilis regarded as one of the causative agents of endogenous diarrhea...
ifBacteroides fragiliswere identified in a swab from a diabetic foot ulcer or a decubitus ulcer, it would not have any clinical implications as the ulcers are usually colonized with a high bacterial load of mixed aerobic and anaerobic growth. ...
normal flora of the intestinal tract and to a lesser degree, the respiratory and urogenital cavities of humans and animals; many species formerly classified asBacteroideshave been reclassified as belonging to the genusPrevotella. Many species can be pathogenic. The type species isBacteroides fragilis....
theB. fragilisgroup by the clinical laboratory is often critical for appropriate therapeutic intervention. On blood agar,B. fragilisforms circular, entire, white or gray, 2- to 3-mm colonies that are shiny and smooth. TheB. fragilisgroup can be rather pleomorphic on Gram stain, forming ...
1 Bacteroides Fragilis a ETIOLOGY The genus Bacteroides consists of obligate gram-negative anaerobic rods which are often pleomorphic. The bacteria grow well on blood agar and in enriched media containing peptone and yeast extract (Hofstad, 1986). b DISEASE IN HUMANS AND ANIMALS The bacteria reside...
Bacteroides is an opportunistic, anaerobic, Gram-negative bacilli. Bacteroides fragilis is the most common species involved in human disease.
fragilis. We constructed an ompA1 disruption mutant in B. fragilis 638R (WAL6 OmegaompA1) using insertion-mediated mutagenesis. WAL6 OmegaompA1 formed much smaller colonies and had smaller, rounder forms on Gram stain analysis than the parental strain or other unrelated disruption mutants. SDS-...
