A collection of 54 unrelated Streptococcus agalactiae strains isolated from
cerebrospinal fluid samples from neonates and 60 unrelated strains isolated
from carriers that had been previously studied by multilocus enzyme
electrophoresis (R. Quentin, H. Huet, F.-S. Wang, P. Geslin, A. Goudeau,
and R. K. Selander, J. Clin. Microbiol. 33:2576-2581, 1995) were
characterized by randomly amplified polymorphic DNA (RAPD) assay. Four
primers, 5'AGGGGGTTCC3', 5'AACGCGCAAC3', 5'GCATCAATCT3', and
5'AGTCGGGTGG3', named OPS16, AP42, A4, and OPS11, respectively, were
selected from 29 primers tested. This investigation identified 71 RAPD
types. The three families of strains defined by multilocus enzyme
electrophoresis analysis, which contain most of the cerebrospinal fluid
isolates, were also identified by clustering analysis of RAPD data. Each of
these three groups exhibits specific RAPD patterns or fragments. The
discriminatory power of the RAPD typing method was also evaluated. The
simplest typing scheme was obtained by the combination of RAPD typing done
with primers AP42 and OPS11 and serotyping (index of discrimination, 0.97).
