“Compared with infants born to lightly colonized women, those born to heavily colonized women have 2.5 times the risk of infection. Neonates born to mothers who have GBS bacteriuria at any time during pregnancy are known to be more frequently and more heavily colonized with GBS and are more likely to develop sepsis. Infections that occur in the first two days of life usually are caused by exposure to maternal organisms. Risk factors for neonatal transmission and infection are listed in Table 1. Compared with term newborns, preterm and low-birth-weight infants have increased rates of GBS sepsis.”

Genetic risk factor for premature birth found.
University of California, San Diego Health Sciences. ScienceDaily. ScienceDaily, 6 May 2014.
“Researchers have discovered a genetic risk factor for premature birth. The risk factor is related to a gene that codes for a protein that the scientists have found helps the body’s immune cells recognize and fight Group B Streptococcus (GBS) bacteria. These bacteria are found in the vagina or lower gastrointestinal tract of approximately 15 to 20 percent of healthy women, but may cause life-threatening infections, such as sepsis or meningitis in newborns, especially those born prematurely.”
