  • Salicylate culture media for inactivation of bacterial growth inhibitors
    Patent number: 4602007
    Abstract: This invention encompasses methods and reagents for inactivation of bacterial growth inhibitors present in blood, serum or plasma. It has been found that salicylates and closely related compounds will neutralize bacterial growth inhibitors present in the blood of many patients. The addition of salicylate to conventional growth medium also provides a reagent for monitoring the antibiotic levels in blood by enabling measurement of the effect of the antibiotic against a standard test organism without interference from the bacterial growth inhibitor present in sera.
    Type: Grant
    Filed: November 5, 1984
    Date of Patent: July 22, 1986
    Assignee: Abbott Laboratories
    Inventors: George M. Fukui, Herbert J. Spencer, Laurens R. Williams, II
