Evaluation of Two Supplemented Culture Media for Long-Term, Room-Temperature Preservation of Streptococcus pneumoniae Strains

Figure 2

Pneumococcal survival-time curves based on the means and standard deviation of CFU of five pneumococcal strains stored on TH-HYC and TH-SYC agar, along test 2. CFU (+): the number of CFU was expressed as crosses of growth in the recovery plate. TH-HYC: Todd-Hewitt/Hemoglobin/Yeast/Charcoal. TH-SYC: Todd-Hewitt/Skim-Milk/Yeast/Charcoal.
