Determined in 5 uninfected hamsters and 5 infected hamsters at each time point. The value represents the mean ± standard deviation of the group.
Number of total splenocytes (millions) obtained from the spleen of the animals. Enumerated in a Neubauer chamber by light microscopy.
Percentage of positive cells determined by flow cytometry.
Number of cells (millions): calculated from the total number of cells multiplied by the percentage of cells positive by flow cytometry.
Granulocytes: percentage of granulocytes determined by Side Scatter and Forward Scatter of cells by flow cytometry.
p<0.001 uninfected vs. infected groups;
p<0.01; uninfected vs. infected groups;
p<0.05, uninfected vs. infected groups (Kruskal-Wallis test);
p<0.001, uninfected vs. infected groups (Tukey-Kramer Multiple comparisons test).
