Abstract
Traditional methods for the diagnosis of parasitic helminth infections of livestock have a number of limitations, such as the inability to distinguish mixed-species infections, a heavy reliance on technical experience and also sub-sampling errors. Some of these limitations may be overcome through the development of rapid and accurate DNA-based tests. For example, DNA-based tests can specifically detect individual species in a mixed infection at either the larval or egg stages, in the absence of morphological differences among species. Even so, some diagnostic problems remain the same, irrespective of whether a DNA-based or traditional method is used. For example, sub-sampling errors from an aggregated distribution are likely to persist. It is proposed, however, that DNA-based diagnostic technologies offer an opportunity to expand diagnostic capabilities, and are discussed in the current review. The future introduction of DNA-based diagnostic technologies into routine diagnostic settings will also be discussed.
