Real-time PCR-based methods for detection of Mycobacterium avium subsp. paratuberculosis in water and milk.

A real-time PCR assay for quantitative detection of Mycobacterium avium paratuberculosis has been developed. It targets and amplifies sequences from the IS900 insertion element which is specific for this bacterium, and includes an internal amplification control. The assay was tested against 18 isolates of M.

Use of multilocus variable-number tandem-repeat analysis for typing Mycobacterium avium subsp. paratuberculosis.

The etiology of Crohn's disease in humans is largely unknown. Clinical signs of Crohn's disease partly resemble the clinical picture of Johne's disease in ruminants caused by Mycobacterium avium subsp. paratuberculosis.

A molecular beacon-based real-time NASBA assay for detection of Mycobacterium avium subsp. paratuberculosis in water and milk.

A molecular beacon-based real-time NASBA assay for detection and identification of Mycobacterium avium subsp. paratuberculosis has been developed. It targets and amplifies sequences from the dnaA gene which are specific for this bacterium.
