A DNA sequence capture extraction method for detection of Mycobacterium avium subspecies paratuberculosis in feces and tissue samples.

Culturing of Mycobacterium avium subspecies paratuberculosis (Map) remains difficult and is time consuming. An alternative for the rapid detection of Map in samples is PCR. We have developed a sensitive DNA-extraction method based on sequence capture for the rapid detection of M.

Newly developed primers for the detection of Mycobacterium avium subspecies paratuberculosis.

Recent publications reported the existence of IS900 like sequences in mycobacteria different from Mycobacterium avium subspecies paratuberculosis (Map). The primers used for IS900 detection of Map have amplified these sequences causing false positive results. In this study, we have developed two new PCR assays for the detection of Map.
