Transcervical Mouse Infections with Chlamydia trachomatis and Determination of Bacterial Burden 小鼠宫颈沙眼衣原体感染及细菌负荷测定 作者:Karthika Rajeeve and Rajeeve Sivadasan日期:02/05/2020,浏览量:344,Q&A: 0
Chlamydia trachomatis is an obligate human pathogen. It infects the genital tract of humans ascending into the fallopian tube, exacerbated by chronic pelvic pain, pelvic inflammatory disease, and fallopian tube scaring resulting in infertility and other malignancies. The major hurdle in controlling chlamydial spread is that the ...
