The results of study show:1. White pulp and red pulp in parenchyma of spleen of embryo can be obviously discerned after 18 days. Periarterial lymphoid sheath and ellipsoid periarterial lymphoid sheath also can be obviously discerned in spleen of 4 days chicken. T, B lymphocytes in appendix basement of embryo emerge after 20 days. It is the initial shape of cecal tonsil. Crypt structure of conjunction of esophago and stomachus glandularis form obviously at 4 days. It is the initial shape of esophago tonsil. The germinal center firstly emerges in these three organs at 14 days. With the increase of day age, the characteristic structure peripheral immune organs gradually develop mature. Spleen achieve mature at 21 days and cecal tonsil at 35 days.2. IgM~+ and IgA~+ cells in spleen of embryo emerge at 15 days. IgG~+ cell, CD3~+ and CD8~+T lymphocytes of embryo emerge at 20 days. CD3~+, CD8~+ and IgM~+ cells in cecal tonsil of embryo emerge at 20 days. However CD4~+, IgG~+ and IgA~+ cells all emerge in 1 day age chicken out of crust. CD3~+, CD4~+, CD8~+, IgM~+ and IgG~+ cells in esophago tonsil of embryo all emerge at 20 days. However IgA~+ cells emerge in 1 day age chicken out of crust.3. The amount of T, B lymphocytes in peripheral immune organs increase follow with the increase of day age, and hold an upgrade tendency. The amount of T, B lymphocytes in spleen achieved stabilization at 21 days, and in tonsil of esophago and appendix at 35 days.

研究结果表明：1、在组织结构方面，脾脏实质内的白髓与红髓在胚胎18日龄后明显可辨，4日龄雏鸡脾脏中形成明显可辨的动脉周围淋巴鞘和椭球周围淋巴鞘；盲肠基部T、B淋巴细胞在胚胎20日龄时开始出现，即初步形成盲肠扁桃体；食管与腺胃结合处在4日龄时形成明显的隐窝结构，即食管扁桃体初步形成；14日龄时，三种器官中首次出现生发中心；随着日龄的增长，外周免疫器官特征结构不断发育成熟，脾脏在21日龄时达到成熟水平，盲肠扁桃体和食管扁桃体在35日龄时达到成熟水平。2、在T、B淋巴细胞出现时间方面，脾脏中IgM~+和IgA~+细胞在胚胎15日龄时开始出现，IgG~+细胞、CD3~+和CD8~+T淋巴细胞在胚胎18日龄时出现，CD4~+细胞在胚胎20日龄时出现；盲肠扁桃体中CD3~+、CD8~+和IgM~+细胞在胚胎20日龄时开始出现，而CD4~+、IgG~+和IgA~+细胞均在雏鸡出壳后1日龄时出现；食管扁桃体中CD3~+、CD4~+、CD8~+、IgM~+和IgG~+细胞均在胚胎20日龄时开始出现，而IgA~+细胞则在雏鸡出壳后1日龄时出现。3、在T、B淋巴细胞数量变化方面，外周免疫器官中T、B淋巴细胞的数量随日龄增长，整体均呈上升趋势。

Objective To comprehend the infectious condition of 6 pathogens e.g. Ng, Uu, Mh, Ct, eumycetes and Trichomonas, and their drug susceptibility. Methods Colloidal labeling assay was applied into the detection of Chlamydia, STD mycoplasm detecting kit was applied into the culture of Chlamydia.
