Search for common antigens to develop universal vaccines to control avian mites, poultry red mites, tropical fowl mites, and northern fowl mitesワクモ（Dermanyssus gallinae）は鳥類に寄生する吸血性のダニで、鶏に貧血や産卵数や産卵率の低下を引き起こし、国内外の多くの養鶏場で深刻な生産性の低下を引き起こしているほか、動物福祉の観点からも問題視されている。ワクモの防除は、殺虫剤の使用により行われているが、薬剤耐性ダニの出現により、現行の対策に変わる新規防除法の確立が望まれている。近年、新規防除法としてワクチンによる防除法の開発が注目されている。しかし、野外への応用に向けて、さらなる効果の改善が求められおり、複数抗原を組み合わせたカクテルワクチンの開発が必要である。また、その他の家禽の吸血性のダニであるトリサシダニ(Ornithonyssus sylviarum)やミナミトリサシダニ(Ornithonyssus bursa ...
