Micoplasma hominis infection is caused by the bacteria Mycoplasma hominis.〔Taylor-Robinson D, Clin Infect Dis. 1996 Oct;23(4):671-82; quiz 683-4. Infections due to species of Mycoplasma and Ureaplasma: an update.〕 Micoplasma hominis infection is spread through vaginal intercourse, oral-to-genital contact, and vertically from mother to her infant in utero or by the colonization by the bacteria as the baby descends through the birth canal or by nosocomial acquisition through transplanted tissues.〔 (【引用サイトリンク】 url = http://emedicine.medscape.com/article/231470-overview#a5 ) 〕 The presence of genital M. hominis infection is related to sexual practices behavior and income level but not ethnicity. The M. hominis bacteria is more common in African Americans than in Caucasians, but it is not determined if this is racial difference or socioeconomic status.〔(【引用サイトリンク】 url = http://emedicine.medscape.com/article/231470-overview#a6 )〕 It is not present in the normal vaginal microbiota. It can also be present in bacterial vaginosis. ==Signs and symptoms== Those with urogenital or extragenital infections caused by ''M. homonis'' have symptoms similar to other sexually transmitted infections and its presence cannot be determined by its symptoms. Unfortunately, some clinicians are not completely familiar with Mycoplasma and Ureaplasma species as sexually transmitted diseases. There is also a lack of testing facilities that can culture or use PCR testing to diagnose this infection. This infection is sometimes identified as 'last resort" after all other infections or diseases are ruled out. This is especially true if antibiotic treatment with medications are ineffective.The following effects and symptoms can be caused by Mycoplasma hominis: * pyelonephritis * cystitis * pelvic inflammatory disease * endometritis * chorioamnionitis * infectious arthritis * surgical and nonsurgical wound infections * bacteremia * pneumonia * meningitis * salpingitis * urethritis * septic arthritis * cervicitis * PID ''Mycoplasma hominis'' often is present in polymicrobial infections, When present in patients with some of these conditions being one of several organisms may be present causing the infection.〔(【引用サイトリンク】 url = http://emedicine.medscape.com/article/231470-clinical ) 〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Mycoplasma hominis infection」の詳細全文を読む スポンサード リンク
