title: A real-time PCR assay for the specific identification of serotype O:9 of Yersinia enterocolitica.
abstract: A real-time PCR assay was developed based on a 181-bp fragment of the recently cloned per gene, including an internal amplification control (124 bp), for the detection of Yersinia enterocolitica O:9 (Ye O:9). The validation included 48 Ye O:9, 33 Y. enterocolitica non-O:9 and 35 other closely-related bacterial strains, containing per gene homologies. The assay was specific for the Ye O:9 tested, the detection limit was 1-10 genome copies of purified DNA and amplification efficiency was between 90.5-103%, indicating a linear regression throughout the detection window.
