THURSDAY, Aug. 2 HealthDay News)--obtain a change in the composition of intestinal microbes that normally would cause health problems such as weight and inflammation may actually be beneficial for the pregnant, according to the researchers.
In conducting the research, published in the Aug. 3 edition of the journal cell, scientists tested stool samples taken from 91 women in pregnancy. It appeared that the composition of intestinal microbes women changing in time, from the first quarter of their pregnancy at the third trimester.
"This is the first in-depth characterization of intestinal microbiota associated with pregnancy," study senior author, Ruth Ley, Cornell University, said in a news release. log "The findings suggest that our body have coevolved with the microbiota and can actually use them as a tool to help you change the metabolism of the mother--to promote the development of the fetus."
In the course of their pregnancy, intestinal microbes women became less "normal" and less varied. Researchers also found that the number of bacteria beneficial bacteria levels associated with rejected as the disease has increased. There was also evidence that inflammation increased during the pregnancies of women.
"Changes in intestinal microbes do not relate to diet, so we think that the immune system or the hormones play a role," Ley noted.
The researchers then passed the transfer of pregnant women healthy mouse intestinal bacteria. They found mice that received transfer of the bacteria from the third trimester got fatter and had higher levels of inflammation markers in blood sugar metabolism, and worse than the mice that received the first trimester of the micro-organism.
"By the third trimester, the microbiota may entail changes in metabolism," Lei said. "In the context of pregnancy, these changes in the mother are healthy metabolic because they promote the energy storage in fat tissue support and assistance of the fetus. Beyond the pregnancy, however, these changes may lead to the development of type 2 diabetes and other health problems. "
