Neutralization of A. phagocytophilum infection of HL-60 cells by Asp62 and Asp55 rabbit peptide antisera. After A. phagocytophilum pretreated with Asp62 or Asp55 rabbit peptide antiserum or preimmune sera was added, HL-60 cells were cultured for 2 to 3 days. The numbers of A. phagocytophilum bacteria were counted after Diff-Quik staining, using 100 cells per well and triplicate wells. The values are the means and standard deviations (n = 3). An asterisk indicates that there is a significant difference between the peptide antiserum and the preimmune serum (P < 0.05). The data are representative of three independent experiments.
