a
FAFLP profiles were obtained with the EcoRI+0 and MseI+T primer pair. All the isolates are identical by PFGE, ribotyping, and emm1 subtype (Table 1).
b
The presence or absence of differential fragments is shown. +, a fragment characteristically present in that FAFLP profile; −, characteristic absence of fragment from that FAFLP profile.
c
Isolates with these two FAFLP profiles exhibited further polymorphisms (data not shown).
