  1. aThe analyzed 68 GBS isolates were collected during study period, including from cases born in the studying hospitals or born elsewhere but transferred to the studying hospitals for medical treatment after delivery
  2. bCSF cerebrospinal fluid
  3. cCompared with early-onset disease, serotypes distribution for late-onset disease was not statistically different (X2 = 2.1062, P = 0.5506)
