Anti-chlamydia antibody determination in mice housed under LD conditions. Mice were infected with C. muridarum at either ZT3 or ZT15 and serum samples were collected at different time points after infection. (A) IgG was significantly higher in mice infected at ZT15 in the first week of infection compared to mice infected at ZT3 (*p < 0.05). However, during weeks two and three of infection, IgG was significantly higher in mice infected at ZT3 compared to mice infected at ZT15 (**p < 0.01). (B) IgG2C was significantly higher in mice infected at ZT3 compared to mice infected at ZT15 (**p < 0.01, ****p < 0.0001). (C) No significant difference in IgA levels between mice infected at ZT3 or ZT15. (D) Significant increase in IgA levels in mice infected at ZT15 in the fourth week of infection compared to mice infected at ZT3 (**p < 0.01). The data was analysed using a one-way ANOVA and post hoc test.
