Fig. 1From: Pneumococcal colonization and invasive disease studied in a porcine modelBacteraemia in piglets due inoculation with S. pneumoniae. Bacteraemia was monitored on a daily base in piglets infected intravenously (Panel a) or intranasally (Panel b) with S. pneumoniae by plating EDTA blood on selective agar plates. Mean bacterial counts are depicted, error bars represent standard error of the mean. Open symbols represent piglets infected with a low dose, closed symbols piglets infected with a high dose. Each symbol represents 3 − 5 piglets, error bars show standard deviation. ** p < 0.01; *** p < 0.001 (ANOVA)Back to article page
