  1. Capsular polysaccharide types of group B streptococcal isolates from neonates with early-onset systemic infection.

    Article - En anglais

    The distribution of serotypes of group B streptococci (GBS) isolated from 67 infants with early-onset sepsis are described.

    Case-infants were assembled from 13 hospitals across the United States from 15 July 1995 to 5 February 1997 through prospective active surveillance.

    The distribution of GBS serotypes was Ia, 40% ; Ib, 9% ; II, 6% ; III, 27% ; V, 15% ; and nontypeable, 3%. Type V occurred more frequently in the northeast region (New York and New Jersey) than in other regions (29% vs. 9%, P=06).

    Conversely, type III occurred significantly less frequently in the northeast region than other regions (10% vs. 35%, P=04).

    GBS types Ia, III, and V accounted for 82% of the isolates.

    This report supports previous observations about the emergence of GBS type V, but our data caution that conclusions about serotype distributions based on one geographic location or on a small number of patients may not be generally applicable.

    Continued monitoring seems necessary for the design of a GBS vaccine.
