The prevalence of group B streptococcal (GBS) colonization was studied in 136 pregnant women and their newborn infants by collecting vaginal and rectal swabs from the mothers and throat, rectal, and umbilical swabs from their infants. Maternal and infant colonization rates were 22% and 23%, respectively. One-third of infants born to colonized mothers and 15% of infants born to noncolonized mothers had GBS isolated. Of GBS-colonized infants, 50% remained colonized at the mean age of 2 months. Type V was the commonest serotype among GBS isolates from mothers and infants; type III strains were uncommon. The rarity of GBS disease in Gambian infants may be due to low rates of maternal carriage with the more virulent GBS serotypes.
通过采集136名孕妇及其新生儿的阴道和直肠拭子、母亲的咽喉、直肠和脐带拭子，研究了B族链球菌（GBS）的定植率。母亲和婴儿的定植率分别为22%和23%。定植母亲所生婴儿中有三分之一以及未定植母亲所生婴儿中有15%的GBS检测呈阳性。在GBS定植的婴儿中，50%在平均2个月大时仍处于定植状态。V型是母亲和婴儿GBS分离株中最常见的血清型；III型菌株不常见。冈比亚婴儿GBS疾病罕见可能是由于携带毒性更强的GBS血清型的母亲比例较低。
