Recovery of Streptococcus pneumoniae from mock specimens using flocked, Dacron and rayon swabs.

Anotype 19Frb type tested swab type from three the data wass) was determined by ica) as determined by the coefficient of variatSD, Standard deviation. ¥ Represents skim milk-tryptone-glucose-glycerol (STGG) media simulating a 100% release of S. pneumoniae from an inoculated swab into the STGG media and is used as a reference to calculate the percentage of recovery. ¶ Pooled replicates of each swab type from three independent experiments performed on three different days. ‡aFU*arCFU/mL)Mean of colony forming units (CFU) obtained from 9 different replicates of each swab type tested. † Percentage of recovery was calculated as the proportion of the mean CFU recovered from each swab type divided by the control (simulated 100% CFU recovery) from each respective S. pneumoniae serotypes. §S. pneumoniae serotype 19F tested in this study corresponds to the American Type Culture Collection (ATCC 49619) strain.
