We developed a murine model of systemic infection with Chlamydia trachomatis biovar lymphogranuloma venereum (LGV). The pathological features of this infection resemble those of human LGV infection since both are characterized by granuloma formation. Mice developed resistance to reinfection with LGV, and this resistance was based on cellular immune mechanisms since it was transferable with immune spleen cells but not with immune serum. Resistance required viable organisms for induction. We compared LGV biovar infection with trachoma biovar infection. Trachoma biovar produced similar but less marked microbiological and pathological features. Cross-immunity was less apparent between serovars from trachoma and LGV biovars than it was between serovars within the same biovar. This model of systemic C. trachomatis infection will be useful in exploring virulence features of LGV.
我们构建了沙眼衣原体性病淋巴肉芽肿生物变种(LGV)全身感染的小鼠模型。这种感染的病理特征与人类LGV感染相似,因为两者均以肉芽肿形成为特征。小鼠对LGV再感染产生了抵抗力,且这种抵抗力基于细胞免疫机制,因为它可通过免疫脾细胞而非免疫血清进行转移。抵抗力的诱导需要活的病原体。我们比较了LGV生物变种感染与沙眼生物变种感染。沙眼生物变种产生了相似但不太明显的微生物学和病理学特征。沙眼生物变种和LGV生物变种血清型之间的交叉免疫比同一生物变种内血清型之间的交叉免疫不太明显。这种沙眼衣原体全身感染模型将有助于探索LGV的毒力特征。
