The researchers noted that some anaerobic bacteria significantly increased the probability that will produce a preterm birth.
The presence of certain bacteria in the vagina and the cervix may increase the risk of preterm birth, while another type of bacterial flora in these areas of the reproductive tract may prevent preterm birth (before week 37 of pregnancy) baby, as he has discovered a new study of the Perelman School of Medicine at the University of Pennsylvania (United States) carried out by a multidisciplinary team of researchers, which includes experts in Immunology and microbiology, among others.
Prematurity is the leading cause of death in young children worldwide
The authors of the work samples of vaginal around 2,000 pregnant women, obtained at three different times of gestation, with the aim of identifying the colonies of microbes present both in the cervix and the vagina – and not only in the uterus- and found that certain species of bifidobacteria and Lactobacilli reduce the risk of preterm birth, and that other types of microorganisms , in particular some anaerobic bacteria, significantly increased the probability that will produce a preterm birth.
According to UNICEF, prematurity is the leading cause of death in young children worldwide. And it is that babies who survive a preterm birth often suffer from various complications and childhood health problems, such as respiratory and cardiovascular disorders, malformations, or loss of vision, among others, and the consequences can also accompany them throughout his adult life, hence the importance of determining its causes and prevent its occurrence.
Dr. Michal Elovitz, Professor of obstetrics and Gynecology at the Perelman School of Medicine at the University of Pennsylvania, and director of research, has explained that his findings, if they are confirmed in new studies, would detect women at risk of suffering a premature delivery, as well as to develop treatments based to eliminate the bad cervical bacteria, or favour the proliferation of good bacteria that help prevent preterm birth.
