Of the 130 alpha-hemolytic streptococci, 26 were identified as S. All 83 pneumococcal types were in complete agreement with each of the different test methods. pneumoniae and on the clinical isolates that produced serological cross reactions with the three serological tests and those that were bile-soluble and optochin-sensitive. The Quellung reaction was performed on the 83 capsular types of S. The identification methods included bile solubility, optochin sensitivity, countercurrent-immunoelectrophoresis (CIEP), and coagglutination (CoA) using laboratory-prepared reagents (LPR) and the Phadebact Pneumococcus Test (Phadebact). Five methods for identification of Streptococcus pneumoniae were evaluated with stock strains representing all 83 capsular types and 130 fresh clinical isolates of alpha-hemolytic streptococci. ![]()
