DNA fingerprinting of Australian isolates of <i>Mycobacterium avium subsp paratuberculosis</i> using IS<i>900</i> RFLP

Abstract

The epidemiological features of M paratuberculosis in Australia are similar to those reported in New Zealand, where cattle and sheep are commonly infected with different strains. However, because of the lack of polymorphism identified within the major groups, it is unlikely that DNA fingerprinting will have a significant role in epidemiological studies of Johne's disease, unless an unusual strain in being studied.
