S. pneumoniae D39 strain was propagated in CDM containing either 55 mM glucose or galactose. A group of 5 female MF1 mice received the dose either intranasally (Log10 CFU/ml: for galactose 6.33 for glucose 6.47/mouse) or intravenously through the tail vein (Log10 CFU/ml: for galactose 5.84, for glucose 6.12/mouse). Mice were observed for disease signs over 1 week. The percent survival was analyzed using the Mantel-Cox test. Source data are provided as a Source Data file.
