Accumulating body of research documented that CE is associated with female infertility and several obstetric\/neonatal complications. The major cause of CE is thought to be intrauterine infection represented by common bacteria (Escherichia coli, Enterococcus faecalis, Streptococcus, and Staphylococcus), Mycoplasma\/Ureaplasma, and Mycobacterium. Additionally, local dysbiosis in the female reproductive tract may be involved in the onset and development of CE. Antibiotic treatments against these microorganisms are effective in the elimination of endometrial stromal plasmacytes in the affected patients. Meanwhile, endometriosis is a common female reproductive tract disease characterized by endometriotic tissues (ectopic endometrium) growing outside the uterus and potentially causes chronic pelvic symptoms (dysmenorrhea, dyspareunia, dyschezia, and dysuria), infertility, and ovarian cancers. Endometriosis involves endocrinological, genetic, and epigenetic factors in its etiology and pathogenesis. Recent studies focus on immunological, inflammatory, and infectious aspects of endometriosis and demonstrate several common characteristics between endometriosis and CE. This review aimed to better understand the immunological and microbial backgrounds underlying endometriosis and CE and look into the therapeutic potential of the novel antibiotic treatment strategy against endometriosis in light of endometrial infectious disease.<\/jats:p>","DOI":"10.3390\/ijms24032059","type":"journal-article","created":{"date-parts":[[2023,1,20]],"date-time":"2023-01-20T02:57:11Z","timestamp":1674183431000},"page":"2059","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":47,"title":["Commonalities and Disparities between Endometriosis and Chronic Endometritis: Therapeutic Potential of Novel Antibiotic Treatment Strategy against Ectopic Endometrium"],"prefix":"10.3390","volume":"24","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5693-3139","authenticated-orcid":false,"given":"Kotaro","family":"Kitaya","sequence":"first","affiliation":[{"name":"Infertility Center, Kouseikai Mihara Hospital\/Katsura Mihara Clinic, 6-8, Kamikatsura Miyanogo-cho, Nishikyo-ku, Kyoto 615-8227, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tadahiro","family":"Yasuo","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Gynecology, Otsu City Hospital, Otsu 520-0804, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,1,20]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1000","DOI":"10.5858\/2004-128-1000-RSIAIT","article-title":"Routine syndecan-1 immunohistochemistry aids in the diagnosis of chronic endometritis","volume":"128","author":"Nickell","year":"2004","journal-title":"Arch.
