Characterization of a putative nuclear receptor from Onchocerca volvulus.

abstract：:A Babesia bovis merozoite protein, Bb-1, was localized by immunoelectron microscopy to an apical organelle known as the spherical body. This unique structure appears to be analogous to dense granules of other apicomplexan protozoa. Similar to previously described dense granule proteins of Plasmodium spp., Bb-1 is secr...
