Optochin-resistant variants of Streptococcus pneumoniae.

R Muñoz1, A Fenoll, D Vicioso, J Casal.   

Abstract

Ten Streptococcus pneumoniae clinical isolates, possessing physiologically typical pneumococcal characteristics, showed optochin-susceptible and optochin-resistant colonies around the optochin disk, when tested for optochin susceptibility. Equivocal optochin disk test results should be confirmed by bile solubility, agglutination tests, or both.
