Major differences observed between the eight isolates.

A difference is considered as major when it affected more than three base pairs. The position of the differences is given relative to the alignment of the eight isolates. The presence of the difference is indicated for each isolate by a cross. The type of difference (deletions, insertions or other) is described. If the difference occurred in a non-coding region it was labeled by a NC and by C when it occurred in a coding region. Finally the region or gene affected by the variation is given.
