Susceptibility to five antimicrobial agents of strains of the Bacteroides fragilis group isolated in Brazil.
The in vitro activity of metronidazole, chloramphenicol, clindamycin, cefoxitin, and carbenicillin was tested by an agar dilution method against 228 strains of the Bacteroides fragilis group isolated from human intestinal microbiota during 1981 and 1982. All the strains were susceptible to metronidazole. Resistance rates for chloramphenicol, clindamycin, cefoxitin, and carbenicillin were 2, 37,...
متن کاملBacteroides species: maintenance of laboratory strains.
A medium composed of blood agar base (40 g/liter), yeast extract (5 g/liter), and cysteine hydrochloride (0.05 g/liter), completely filling screw-cap tubes (13 by 100 mm), can keep Bacteroides species alive for at least 10 months without refrigeration.
متن کاملEvaluation of Fluoretec-M for detection of oral strains of Bacteroides asaccharolyticus and Bacteroides melaninogenicus.
Fluoretec-M is a polyvalent conjugate used in direct fluorescent-antibody staining for identification of the Bacteroides asaccharolyticus-Bacteroides melaninogenicus group. The Fluoretec-M reagent detected all oral and nonoral test strains of B. melaninogaenicus subsp. intermedius, all test strains of B. melaninogenicus subsp. melaninogenicus, and the nonoral strains of B. asaccharolyticus. Ho...
متن کاملProduction of phenylacetic acid by strains of Bacteroides asaccharolyticus and Bacteroides gingivalis (sp. nov.).
Strains of Bacteroides asaccharolyticus and Bacteroides melaninogenicus subspecies isolated from human and animal sources were examined for the production of phenylacetic acid. B. asaccharolyticus strains isolated from sites in humans and monkeys always produced phenylacetic acid. B. asaccharolyticus strains isolated from human nonoral sites consistently failed to produce this product. This met...
متن کاملGenomic Diversity of Enterotoxigenic Strains of Bacteroides fragilis
Enterotoxigenic (ETBF) strains of Bacteroides fragilis are the subset of strains that secrete a toxin called fragilysin (Bft). Although ETBF strains are known to cause diarrheal disease and have recently been associated with colorectal cancer, they have not been well characterized. By sequencing the complete genome of four ETBF strains, we found that these strains exhibit considerable variation...
