Figure 4From: Effect of Ampicillin on the kinetics of colonization of Streptococcus pneumoniae and Lactobacillus fermentum in the respiratory tract of miceColonization S. pneumoniae in mice inoculated intranasally with L. fermentum (4 doses of 1 × 107 CFU/dose), challenged with S. pneumoniae (1 × 108 CFU/mice) and treated with 4 doses of Ampicillin compared with mice treated only with the pathogen and antibiotics. The figures express the number of pathogen in lung.Back to article page
