    • Polypeptide and polynucleotide vaccines effective to treat or prevent infection of a mammal, such as a dog, a cat, or a human, by a protozoan. Methods of treatment and prevention are also provided, including therapeutic administration of the vaccine to an infected mammal to prevent progression of infection to a chronic debilitating disease state. Preferred embodiments of the polynucleotide vaccine contain nucleotide coding regions that encode polypeptides that are surface-associated or secreted by T. cruzi. Optionally the efficacy of the polynucleotide vaccine is increased by inclusion of a nucleotide coding region encoding a cytokine. Preferred embodiments of the polypeptide vaccine include immunogenic peptides that contain membrane transducing sequences that allow the polypeptides to translocate across a mammalian cell membrane.
    • 通过原生动物有效治疗或预防哺乳动物(例如狗,猫或人)感染的多肽和多核苷酸疫苗。 还提供了治疗和预防方法,包括将疫苗治疗性给予受感染的哺乳动物以预防感染进展为慢性衰弱疾病状态。 多核苷酸疫苗的优选实施方案含有编码由克氏锥虫表面缔合或分泌的多肽的核苷酸编码区。 任选地,通过包含编码细胞因子的核苷酸编码区来提高多核苷酸疫苗的功效。 多肽疫苗的优选实施方案包括含有允许多肽转移穿过哺乳动物细胞膜的膜转导序列的免疫原性肽。
