The most common molecular technique used to identify species of pathogenic bacteria are nucleic acid hybridisation and polymerase chain reactions (PCR). Nucleic acid hybridisation uses synthetic nucleic acid probes (specific for a particular species) that are applied to genetic material extracted from the pathogen. Probes can be used to detect DNA and RNA. | The most common molecular technique used to identify species of pathogenic bacteria are nucleic acid hybridisation and polymerase chain reactions (PCR).
