Immunoglobulin levels of control and D. morbifera Léveille-treated mice. a IgA, b IgG1, c IgG2A, d IgG2B, e IgG3 and f IgM. All the tested immunoglobulins showed a dose-dependent reduction in treatment with D. moribifera Léveille, except for IgA. Group VI showed a significant reduction IgG2A levels. IgG2B was significantly reduced in groups III, V and VI. IgG3 showed significant suppression in group VI mice. No significant difference was observed between the IgM treatment groups. (* = P value < 0.05; ** = P value < 0.01; *** = P value< 0.001; **** = P value < 0.0001; all the comparisons were made using the untreated control groups)
