IS6110 restriction fragment length polymorphism typing
is now established as the primary typing method for Mycobacterium
tuberculosis. It has been assumed that the position of bands is
random. Thus, the discrimination of the technique increases in
proportion to the copy number. Two collections of M. tuberculosis were investigated to test this hypothesis. We
identified 33 positions in isolates from a Tanzanian collection and 25 positions in isolates from a London, United Kingdom, collection where
bands were significantly more likely to be present than would be
expected by chance. These data suggest that band position is not
random, and this possibility may have an impact on the interpretation
of molecular epidemiological studies of M. tuberculosis.
