猫弓形虫疫苗的研究进展

Advances in research on Toxoplasma gondii vaccine in cats

  • 摘要: 弓形虫是一种专性细胞内寄生原虫,能够感染包括人在内的绝大多数恒温动物。弓形虫病是由弓形虫引起的一种人兽共患病,该病不仅会对畜牧业造成极大的经济损失,还对人类健康构成重大威胁。猫科动物是弓形虫的终末宿主。猫在弓形虫病的传播中占主导地位。因此,防控弓形虫病的核心是防控猫弓形虫病,研制猫弓形虫疫苗对防控弓形虫病具有极其重要的意义。文章综述了猫弓形虫灭活疫苗、核酸疫苗、亚单位疫苗、减毒活疫苗等的研究进展,旨在为猫弓形虫疫苗的研究开发提供思路。

     

    Abstract: Toxoplasma gondii is an obligate intracellular parasite that infects most endotherms, including humans. Toxoplasmosis is a zoonosis caused by Toxoplasma gondii, which not only causes great economic loss to animal husbandry, but also poses a great threat to human health. The feline family is the definitive host of Toxoplasma gondii. Cats dominate the transmission of toxoplasmosis. Therefore, the core of prevention and control of toxoplasmosis is to prevent and control toxoplasmosis in cats, and the development of vaccine for prevention and control of toxoplasmosis is of great significance. In this paper, the research progress of inactivated vaccine, nucleic acid vaccine, subunit vaccine and attenuated live vaccine of Toxoplasma gondii was reviewed, aiming to provide ideas for the research and development of Toxoplasma gondii vaccine.
