Abstract: A novel galectin, a polynucleotide encoding the same, a vector and a transformant comprising the polynucleotide, an antibody against the galectin, and a screening method for screening a substance capable of modifying the galectin, are disclosed. According to the galectin, polynucleotide, or vector, it is possible, for example, to exterminate ticks, or to treat or prevent tick-borne infections such as rickettsiosis, filariasis, Q fever, African recurrent fever, or viral encephalitis.

Abstract: The present invention provides a gene encoding a protein from merozoite of Babesia caballi, a recombinant protein of Babesia caballi, and an antibody capable specifically binding to a 48 kDa protein of rhoptry of Babesia caballi merozoite. In accordance with the present invention, it is possible to stably prepare the 48 kDa protein of rhoptry of Babesia caballi and the gene encoding said protein in a large amount with the recombinant DNA technique. The present invention also provides a method for diagnosing equine babesiasis which comprises either specifically detecting anti-Babesia caballi antibody present in equine blood by using the recombinant protein of present invention as an antigen or detecting the presence of Babesia caballi merozoite in equine blood by using the antibody of the present invention.
