FIG 3.
TEM analysis of ΔC-CHIKV in infected BHK-21 cells. BHK-21 cells were infected with WT CHIKV or ΔC-CHIKV at an MOI of 0.01. WT CHIKV- and ΔC-CHIKV-infected cells were fixed for TEM analysis at 24 hpi and 84 hpi, respectively. Representative TEM images observed for WT (C and D)- or ΔC-CHIKV (A and B)-infected BHK-21 cells are shown. Budding viruses and NCs are indicated with arrows and arrowheads, respectively.
