Comparison of MLVA types of EcO157 environmental strains with PFGE profile designations.

aSee Table S1 for MLVA data and source information.bXbaI profile in PulseNet database (last checked Dec, 2006) matching designated strain. XbaI patterns EXHX01.3535, EXHX01.3536, EXHX01.3537 were new to the PulseNet database at the time of submission.cFrequency of this XbaI profile in PulseNet database.dBlnI profile in PulseNet database (last checked Dec, 2006) matching designated strain. BlnI patterns EXHA26.1395, EXHA26.1411, EXHA26.1412 are new to the PulseNet database.eClusters of illnesses identified from PFGE profiles submitted to PulseNet as XbaI profile, or both XbaI and BlnI profiles. Designation is by state (2 letter abbreviation):month-2 digit year; Multi, multiple states.fRM5038 and RM5037 were isolated from the same sample of feces; MLVAs 15 and 16 differ by one TR only in locus 4.gXbaI-BlnI profile EXHX01.0047-EXHA26.0015 represents>6% of the PulseNet database (see Table 2).hOne band difference between the profile for this strain and the BlnI PulseNet profile designated.IMajor MLVA type for human clinical strains associated with the spinach outbreak.
