1. Identification of Bacteroides fragilis from clinical samples
Abstract : The members of Bacteroides fragilis group are Gram-negative anaerobic, non-spore forming rods that are present in the normal flora of human intestine. B. fragilis group consists of ten species: B. caccae, B. READ MORE

2. Quinolone resistance in Bacteroides fragilis and Pseudomonas aeruginosa, two opportunistic pathogens
Abstract : Opportunistic pathogens can cause infections in case of structural or functional defects in the host. Examples of Gram-negative opportunists are the Bacteroides fragilis group, anaerobic, non-spore forming rods and the aerobic, non-fermentative rod Pseudomonas aeruginosa. READ MORE

3. Beta-lactam and metronidazole resistance in the Bacteroides fragilis group
Abstract : The Bacteroides fragilis group organisms are anaerobic gram-negative bacilli. Ten species are currently included in this group. Members of the B. fragilis group are the major constituents of the normal colonic microflora and the most commonly encountered anaerobic bacteria in clinical specimens. READ MORE

4. Ecological aspects of antimicrobial susceptibility of anaerobic bacteria in Nicaragua
Abstract : Anaerobic bacteria are the predominant constituents of the normal flora on the skin and the mucous membranes of the human body. They may also act as potent pathogens in a variety of endogenous infections. Antimicrobial resistance is an increasing problem with anaerobic and aerobic bacteria. Different mechanisms for such resistance are known. READ MORE

5. Ecological disturbances and emergence of resistance in the oral and gastrointestinal microflora after drug exposure
Abstract : The exposure of antimicrobial agents and antacids may disturb the ecological balance of the normal microflora. This influence often leads to decreased colonization resistance due to repression of sensitive bacteria and selection of resistant bacteria which have acquired resistance during therapy. READ MORE
