MLVA type is defined by the repeat counts for VNTR1, VNTR3, VNTR4, VNTR5, and VNTR6 (21).
Single-copy locus (21).
Formerly referred to as fim3.
Based on enzyme-linked immunosorbent assay.
Fatal cases.
Signal sequence deletion (nt 26 to 109).
IS481 forward insertion at nt 240.
IS481 reverse insertion at nt 1613.
IS481 forward insertion at nt 1613.
IS481 reverse insertion at nt 240.
