A novel chitinase, a polynucleotide encoding the same, a vector and a transformant containing the polynucleotide, an antibody against the chitinase, and a screening method for a substance that modifies the activity of the chitinase are disclosed. According to the chitinase, polynucleotide, or vector, for example, tick extermination or tick-borne infection (eg, piroplasmosis, Q fever, viral encephalitis, etc.) can be treated or prevented. |
