^aIn England.

^bThe loci of the VNTR profiles are presented in the following order: STTR9-STTR5-STTR6-STTR10pl-STTR3. The number “0” in the VNTR profile represents cases with no amplification of PCR product. PFGE profiles in italics are shown in Fig. 1 and discussed in the main text.

^cDT, definitive phage type.

^dRDNC, reacts but does not conform to known patterns.

^eCSF, cerebrospinal fluid.

^fIsolate OBS-A.

^gIsolate OBS-C.
