Changes in immunity The immune system defends the body against harmful invaders. Changes in body systems Aside from changes in immune function, hormonal changes can also increase your risk for infection. These fluctuations in hormone levels often affect the urinary tract, which is made up of: the kidneys, which are organs that produce urine ureters, which are tubes that carry urine from the kidneys to the bladder bladder, which is where urine is stored urethra, which is a tube that transports urine out of the body As the uterus expands during pregnancy, it puts more pressure on the ureters.

Risks for mother and baby. Risks for mother Some infections that occur during pregnancy pose problems primarily for the mother. Risks for baby Other infections are particularly troublesome for the baby. Risks for both mother and baby Some infections are particularly harmful to both mother and baby.

These include: syphilis listeriosis hepatitis HIV group B streptococcus GBS Antibiotics are effective against syphilis and listeria in the mother and baby, if the infection is diagnosed promptly. The importance of knowledge and ongoing care. How to prevent infections in pregnancy. To help prevent infections during your pregnancy, you should: Regularly wash your hands with soap and water. This is especially important after using the bathroom, preparing raw meat and vegetables, and playing with children.

Cook meats until they are well-done. Never eat undercooked meats, such as hot dogs and deli meats, unless they are re-cooked until hot. Avoid changing cat litter and stay away from wild or pet rodents. Practice safe sex and get tested for sexually transmitted infections.

Make sure your vaccinations are up-to-date. Parenthood Pregnancy Pregnancy Health. Placenta Delivery: What to Expect. Read this next. Medically reviewed by Timothy J.

What does the future hold? The model improved understanding of the immune system much as mapping software that knows which streets are one-way gives better driving directions. The study confirmed immune features of pregnancy that were already known. For instance, the scientists saw that natural killer cells and neutrophils have enhanced action during pregnancy.

The STAT5 pathway is involved in helping another group of immune cells, regulatory T cells, to differentiate. Interestingly, prior research in animals has indicated that regulatory T cells are important for maintaining pregnancy. The next step will be to conduct similar research using blood samples from women who deliver their babies prematurely to see where their trajectories of immune function differ from normal. Scientists from Ghent University in Belgium also contributed to this work.
