New techniques to isolate, clone, and manipulate DNA can now be applied to the detection of enteric pathogens in clinical materials, using specific gene sequences as probes. Although no DNA probes are yet commercially available, several have been developed and applied in research laboratories. In presenting our work on the development of a DNA probe for Campylobacter jejuni and its application to fecal samples, we will address the strategies which can be used in probe development and will outline the technical limitations which now exist in probing samples directly. In addition to using DNA as a diagnostic reagent, the plasmid or chromosomal DNA of enteric pathogens, including Campylobaeter and Salmonella, can be used as an epidemiological tool to differentiate strains of the same species. Preliminary data from experiments on Salmonella enteritidis will be presented.
