![]() ![]() It is in this context that molecular methods come into their own. In such cases the time scale necessary to obtain an identification often precludes practical usage. The ability of the skilled taxonomist begins to fail when there is a requirement to identify rapidly organisms that are small, immature, or present in large numbers. It must be stressed, however, that conventional methods are still extremely valuable and will always remain at the forefront of many diagnostic procedures. The use of nucleic acids for diagnostic purposes offers numerous advantages over conventional methods of identification. ![]() ![]() This has been especially true since the advent of polymerase chain reaction (PCR) technology. The majority of applications have been in such medically related fields as the diagnosis of disease or the identification of disĀ ease vectors, but this emphasis is changing as the potential and range of the techniques becomes more generally recognized. Species Diagnostics Protocols: PCR and Other Nucleic Acid Methods is premised on the rapid development in recent years of the use of nucleic acid-based technology for the identification of various organisms. ![]()
