| A gene encoding Babesia gibsoni thrombospondin-related adhesive protein (BgTRAP), known as a vaccine candidate, was stably expressed in Toxoplasma gondii (Tg/BgTRAP). The molecular weight and the antigenic reaction of recombinant BgTRAP expressed by the Tg/BgTRAP were similar to the original ones expressed by B. gibsoni. To evaluate the antigenicity of the recombinant BgTRAP expressed by T. gondii, the lysates of the recombinant parasite tachyzoites were intraperitoneally injected into mice. The serum collected from Tg/BgTRAP-immunized mouse could react to B. gibsoni parasites, while the serum collected from wild-type T. gondii tachyzoites (Tg/wt)-immunized mice did not. These results indicate that T. gondii could provide a new tool to produce foreign... |

| A novel gene encoding 27-kDa protein was identified by the screening of Babesia gibsoni cDNA library with acutely infected dog serum. The BgP27 is a single copy gene with a predicted open reading frame of 762 bp and 254 amino acids. The phylogenic analysis of the deduced amino acid of BgP27 demonstrated considerable identities with members of Plasmodium berghei circumsporozoite protein family that ranged between 18.4% and 22.8%. The BgP27 was expressed as a glutathione S-transferase fusion protein in Escherichia coli. The serum raised in mice against the recombinant protein specifically reacted with a 27-kDa protein in the extracts of B. gibsoni parasites. Confocal laser scanning microscopic observation showed high fluorescent reactivity with both... |
