Abstract

Objective To analyze the reasons for antigen diversity of Anaplasma phagocytophilum grown in different cells. Methods The P44 transcripts were analyzed using nested RT-PCR, and the P44 proteins were produced as recombinant protein in vitro by insect cell-free protein synthesis system. Results We detected and characterized P44 transcript variants of A. phagocytophilum from THP-1 and HL60 cells. And our study demonstrated the presence of specific antibodies against the 3 type of rP44 proteins that prevailed in infected THP-1 and HL60 cells, probably being suitable as protein antigens for sero-diagnosis of human granulocytic anaplasmosis. Conclusion We demonstrated antigenic diversity of a variety of A. phagocytophilum grown in different cells.
