Fig. 2From: Pneumococcal colonization and invasive disease studied in a porcine modelColonization of S. pneumoniae in the oropharynx of intranasally inoculated piglets. Colonization with S. pneumoniae was detected using a pneumococcal specific qPCR. At day 0 prior to infection, no S. pneumoniae was detected. 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 < 0.05 (ANOVA). 100 pg of DNA is equivalent to approximately 4 × 105 CFUsBack to article page
