中文摘要：

鸡生殖道相关淋巴组织作为泌尿生殖道抵御外界病原微生物入侵的第一道免疫屏障，研究其组成和发育有助于了解蛋鸡生殖道黏膜免疫状态的变化情况，尤其是出壳初期和产蛋期间的免疫状态，从而为蛋鸡生殖道疾病（尤其是沙门氏菌病）的防制提供理论依据，并最终为人们能够食用上健康无污染的鸡蛋奠定基础。因此，作者对鸡生殖道相关淋巴组织的结构基础、发育情况及其免疫功能进行了综述。

英文摘要：

It is of great importance to learn about the changes of reproductive tract mucosal immune status by studying the normal development of hens, especially during the immediate post-hatch and laying period, because the chicken reproductive tract associated lymphoid tissue （RTALT） is the first immune barrier of the genitourinary tract against the invasion of external pathogenic microorganisms. This study can serve as a theoretical basis of the reproductive tract disease prevention （especially salmonellosis） for laying hens, and ultimately achieve the goal of providing pollution-free eggs for people to consume. There- fore, this article on chicken reproductive tract associated lymphoid tissue structural basis for development as well as their im- mune function were reviewed.
