| Babesia gibsoni ribosomal phosphoprotein PO (BgP0) was identified as an immunodominant cross-reactive antigen with B. microti. The BgPO gene is a single copy with a predicted open reading frame of 942 bp and 314 amino acids. The BgP0 was expressed as a glutathione S-transferase fusion protein in Escherichia coli. The serum raised in mice with the recombinant BgPO showed a specific band with a 34-kDa molecular mass in the extracts of B. gibsoni and B. microti merozoites. Furthermore, the intraperitoneal (i.p.) immunization of rBgP0 and Freund's adjuvant induced strong Immoral response consisting of mixed immunoglobulins IgG1 and IgG2a in BALB/c mice. Following the challenge with B. microti, these mice delayed the onset of parasites and significantly reduced... |
