Species-specific detection of Listeria monocytogenes by DNA amplification
1991
Deneer, H.G. | Boychuk, I.
The polymerase chain reaction was used to detect and specifically identify Listeria monocytogenes. A 174-bp region of the listeriolysin O gene was shown to be specifically amplified in L. monocytogenes but not in other species of Listeria or in a number of other gram-positive and gram-negative organisms. Less than 50 organisms could routinely be detected by a procedure involving two rounds of 35 amplification cycles each and without the need for subsequent hybridization with labeled probes.
