Age-dependent replication in suckling BALB/c mice. (A) Time-course whole-body fluorescence images in suckling BALB/c mice at different ages. Suckling BALB/c mice (n = 5 or 6) of indicated ages were infected through i.c. injection with CHIKV-iRFP (104 PFU) diluted in 20 μl of DMEM and were imaged at the indicated time points. (B) Total fluorescence radiant efficiency of the head areas of the iRFP expressing mice in (A) was quantified using Living Image software. (C) Survival curve of the iRFP expressing mice in (A). (D) Time-course body weight changes in suckling mice in (A).
