BACITRACIN DISCS

Product Code TBL 046

  • Description

    Bacitracin Disks are used in the presumptive identification of group A ?-hemolytic streptococci and allow for
    differentiation of group A ? -hemolytic streptococci from other ? -hemolytic streptococci. Group A streptococci have
    been shown to be more sensitive to bacitracin than beta-haemolytic stains of other groups allowing bacitracin to be
    used as a rapid diagnostic agent for presumptive identification of Group A streptococci. S. pyogenes is a betahaemolytic
    species of Gram positive bacteria that is responsible for a wide range of both invasive and non-invasive
    infections. S. pyogenes is the most common bacterial cause of acute pharyngitis, accounting for 15-30% of cases in
    children and 5-10% of cases in adults. Bacitracin discs can save considerable time, labour and materials if used as a
    screening test before serological grouping. Levinson and Frank, who employed Bacitracin impregnated filter paper discs
    for this purpose, observed that many sensitive beta-haemolytic streptococci were of Group A. Steamer et al compared
    Bacitracin disc, fluorescent antibody technique and Lancefield precipitin technique and found that the Bacitracin disc
    technique was most convenient for routine clinical laboratory. Bacitracin sensitivity test along with Furacin and
    Optochin tests are useful for distinguishing Aerococcus viridans and S. milleri from enterococci and Streptococcus mitis.
