Following infection, the percentage of neutrophils (CD45+ CD11b+ Ly6g+ Ly6c+ F4/80−) in the white blood cell (CD45+) population remained low in the peripheral blood from 0 (2.45%) to 4 (1.57%) weeks postinfection, and then it increased beginning 6 weeks (8.18%) and peaked 8 weeks (46.1%) postinfection, still remaining high at the 12th week (45.5%).
