title: [DNA diagnosis in veterinary medicine: II. Polymerase chain reaction (PCR)].
abstract: DNA diagnostic has become very important for genetic and infectious diseases. With a new method, called the polymerase chain reaction (PCR), specific pieces of genomes from viruses, bacteria, parasites or even cells can be amplified more than hundred million fold in a very short time period. For the following reasons this opens a new dimension in diagnostics: (1) The technique is so sensitive that a single virus, bacterium, parasite or cell is sufficient to be detected provided part of its nucleic acid sequence is known. (2) The material does neither need to be fresh nor be stored under special conditions since the nucleic acids are much more stable than e.g. enzymes or other proteins. (3) The method is quicker than the usual immunodetection methods. (4) The polymerase chain reaction has been standardized recently so that it can be carried out in diagnostic laboratories. The purpose of this minireview is to give an introduction into the basic technique and to mention possible and already existing applications in veterinary medicine.
