Figure 2From: Beneficial effect of chronic Staphylococcus aureus infection in a model of multiple sclerosis is mediated through the secretion of extracellular adherence protein Leukocyte counting and flow cytometry. Leukocyte counts (A) were performed in peripheral blood of infected and noninfected myelin oligodendrocyte glycoprotein (MOG)-immunized animals. The leukocyte count was found to be significantly higher in the infected group. Data are represented as means ± SEM of all animals from each group (n = 12, infected; n = 11, noninfected). Flow cytometry was performed in peripheral blood to assess B- and T-cell populations in animals infected with S. aureus and noninfected control group on day 4 postimmunization (pi) (prior to infection) and on day 6 pi (corresponding to day 2 postinfection). B- (B) and T-cell (C) populations were substantially increased in infected animals 2 days after infection. Data are presented as means ± SEM. (n = 4 in each group; *P <0.05; **P <0.01; ***P <0.001).Back to article page
