ELISAs for CXCL9 and CXCL10 were performed on serum harvested from pups 7 days postinfected revealed an increase in both CXCL9 and CXCL10 in mice infected with RRV and Ro1845VP4-G446R, while there was no significant difference after Ro1845 or RRVVP4-R446G infection (Fig. 7A). Here, CXCL9 is linked to infection.
