沙眼衣原体感染可为持续性,常见反复感染。近10年来,对衣原体感染的流行病学、临床表现、诊断方法及沙眼衣原体外膜的抗原结构进行了研究,取得了有价值的成果,但仍未能降低本病之发病率。为了控制此病,有必要对沙眼衣原体感染的免疫应答作进一步了解。吞噬细胞应答在沙眼衣原体感染的局部,嗜中性粒细胞(PMN)是最主要的效应细胞,单核的吞噬细胞不常见,在受感染的粘膜表面,炎性 Chlamydia trachomatis infection can be persistent, common repeated infections. In the recent 10 years, the epidemiology, clinical manifestation and diagnosis of Chlamydial infection and the antigenic structure of Chlamydia trachomatis outer membrane have been studied. Some valuable results have been obtained, but the incidence of this disease has not been reduced yet. In order to control the disease, it is necessary to further understand the immune response of Chlamydia trachomatis infection. Phagocytic responses Localization of C. trachomatis infections, neutrophils (PMNs) are the predominant effector cells, mononuclear phagocytes are uncommon, and on infected mucosal surfaces, inflammation
