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 straight rods...
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.
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....

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...
Comparison to reference genomes of type species Bacteroides fragilis NCTC 9343T, Phocaeicola abscessus CCUG 55929T, and Capsularis zoogleoformans ATCC 33285T showed low relatedness based on the calculated genome-to-genome distance and orthologous average nucleotide identity. Analysis of fatty acid ...
fragilis using the MALDI Biotyper sirius system (Bruker Daltonics, Billerica, MA). The anaerobic bottle from the second blood culture set was flagged as positive after 64 hours of incubation and the Gram stain again showed gram-negative rods. B. fragilis and R. gnavus were both isolated from ...
