[PCR diagnosis of infectious diseases].

The practices based on microbe cultivation are the corner stone of laboratory diagnostics of infectious diseases etiology. However, cultivation-independent molecular methods for microorganism detection are increasingly being used in a routine clinical setting as an important complement to the conventional procedures and, in some cases, they have already become the golden diagnostic standard. The PCR-based methods are used the most frequently.Key words: molecular genetic detection of microorganisms - polymerase chain reaction (PCR).
