چکیده

Difloxacin (A-56619) and A-56620, two novel fluoroquinolones, were tested in comparison with ciprofloxacin, cefoxitin, and combined clindamycin and gentamicin in the treatment of experimentally induced intraabdominal abscess associated with Bacteroides fragilis. Difloxacin was found to be as effective as clindamycin-gentamicin. A-56620, despite achieving subtherapeutic levels in serum, was found to be as effective as cefoxitin. Both difloxacin and A-56620 were effective in vivo against experimentally induced intra-abdominal abscess in rats.

In vitro activity of difloxacin hydrochloride (A-56619), A-56620, and cefixime (CL 284,635; FK 027) against selected genital pathogens.

Management of sexually transmitted diseases is facilitated by having antimicrobial agents with activity against all of the major genital pathogens. Newer quinolones show promise of being active against Neisseria gonorrhoeae and Chlamydia trachomatis. Two quinolones, difloxacin (A-56619) and A-56620, and an oral cephalosporin, cefixime (CL 284,635; FK 027), were evaluated in vitro. All three wer...

In vitro evaluation of S-25930 and S-25932, two new quinolones, against aerobic gram-negative isolates from cancer patients.

The in vitro activity of S-25930 and S-25932, two new 4-quinolones, against 450 aerobic gram-negative organisms isolated from cancer patients was evaluated and compared with the activity of ciprofloxacin, enoxacin, difloxacin (A-56619), and A-56620. Both agents inhibited most members of the family Enterobacteriaceae at concentrations of less than or equal to 2.0 micrograms/ml, but their activit...

Use of lymphokines in treatment of experimental intra-abdominal abscess caused by Bacteroides fragilis.

The role of cell-free soluble factors (lymphokines) derived from mitogen-activated splenic cells of mice previously immunized against Bacteroides fragilis was evaluated in the treatment of B. fragilis intra-abdominal abscess (IAA). Neither clindamycin nor lymphokines alone were effective against an established B. fragilis IAA, but the combination of clindamycin and lymphokines decreased the abs...

Polysaccharide-mediated protection against abscess formation in experimental intra-abdominal sepsis.

Abscess formation is a major complication of intra-abdominal sepsis that causes significant morbidity and mortality. In such cases, Bacteroides fragilis is the predominant anaerobic isolate. In a rat model of intra-abdominal sepsis, the capsular polysaccharide complex (CPC) from B. fragilis promotes abscess formation and when administered sub-cutaneously, protects against this host response by ...
