- Premature birth [ Time Frame: between 22 and 37 completed weeks of pregnancy. ]
- Antenatal :occurence of a miscarriage late [ Time Frame: between 16 and 22 weeks of amenorrhoea ]
- Antenatal : premature delivery [ Time Frame: at week of amenorrhea <= 34, 32, 28 ]
- Antenatal : hospitalisation for risk of premature delivery [ Time Frame: antenatal period ]
- antenatal : Number of day of hospitalisation for risk of premature delivery [ Time Frame: antenatal period ]
- Antenatal : premature rupture of membranes [ Time Frame: before 37 week of amenorrhea ]
- Antenatal : occurence of chorioamnionitis defined by 2 of the following criteria :maternal temperature > 38°C, uterine contractions, Fetid leucorrhoeas, foetal tachycardia > 160bpm, C reactive protein >10mg/l [ Time Frame: antenatal period ]

Infection would be the cause of 40 % of spontaneous premature deliveries. The physiopathological hypothesis accepted is a premature ascent of present bacteria in the low genital ways towards the decidual, the foetal membranes then the amniotic liquid. These bacteria are responsible for an inflammatory reaction to the interface feto-maternal characterized by the production of proinflammatory cytokines and pro-contractants agents (prostaglandins, oxytocin) by the decidual and the membranes.
These mediators cause uterine contractions, a maturation of the uterine collar, a rupture of the membranes then a premature birth.
Several recent publications show on the one hand that Mycoplasma hominis and Ureaplasma spp. are the bacteria most frequently found in the amniotic liquid in the second quarter of the pregnancy and that a positive PCR for these bacteria is associated with a premature birth.
A probable assumption would be that Mycoplasma hominis or Ureaplasma spp. cause a premature birth by infecting the fetal membranes and the decidual, then activating the immune system and the pro-inflammatory production of cytokines. These bacteria are sensitive to antibiotic treatment.
Nevertheless, no randomized controlled trials have been carried out to determine wether an antibiotic treatment would decrease spontaneous prematurity in the case of positive PCR in the amniotic liquid.
