a The fragments were assigned to different size bins (labelled A to G in decreasing order) by visual inspection.
b "Yes" and "No" respectively denote the presence or absence of insertions in the pre- and post-repeat regions as ascertained by PCR-RFLP analysis.
c Calculated for the 120 bands observed in the 100 Thai isolates analysed.
