D-Glucopyranose Glucan and Cefazolin in Prophylaxis of Staphylococcal Wound Infection in a Guinea Pig Model
نویسندگان
چکیده
To determine whether the infection-preventing capability of the neutrophil-activating agent poly-(1-6)-b-Dglucopyranosyl-(1-3)-b-D-glucopyranose glucan (PGG-glucan) can be enhanced with antibiotic prophylaxis, we administered PGG-glucan and cefazolin, alone and in combination, to guinea pigs inoculated with isolates of staphylococci. Guinea pigs receiving both PGG-glucan and cefazolin had 50% infective doses that were 8to 20-fold higher than those obtained with cefazolin alone and 100to 200-fold higher than those obtained with PGG-glucan alone. PGG-glucan and cefazolin are synergistic in their ability to prevent staphylococcal wound infection.

The judicious use of perioperative antibiotic prophylaxis reduces the infectious complications of surgery. However, increased bacterial resistance within hospitals may make antibiotic prophylaxis less effective in the future and alternative strategies are needed. New immunomodulatory agents might prevent wound infections by stimulation of the host immune system. To test this hypothesis, we admi...

The goal of this research was to investigate whether at appendectomy for uncomplicated appendicitis (neither gangrenous nor perforated), the coverage of anaerobes with metronidazole for prophylaxis of infectious comlications of appendectomy has any additional benefit. Appendicitis is the most frequent cause of acute abdomen that requires surgery. The two complications of appendectom...
متن کاملAssociation of borderline oxacillin-susceptible strains of Staphylococcus aureus with surgical wound infections.
Staphylococcus aureus isolates which produce type A staphylococcal beta-lactamase have been associated with wound infections complicating the use of cefazolin prophylaxis in surgery. To further evaluate this finding, 215 wound isolates from 14 cities in the United States were characterized by antimicrobial susceptibility and beta-lactamase type and correlated with the preoperative prophylactic ...
