DGGE is undeniably a valuable approach in screening complex ecosystems on a large scale and in
analyzing various environmental samples in a reduced amount of time. Using this technique, diagnosis of
emerging infections could become easier and faster, and identification of uncultivable pathogens can also
now be facilitated. Although there are limitations, DGGE is an interesting and unique approach that
bridges many molecular biology tools together, and its limitations are primarily attributable to the fact that
it is still a relatively new technique. If improved,
