Abstract
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. avium subspecies paratuberculosis by PCR in fecal and tissue samples. The method detected 102Â Map/g feces using spiked samples, and reached a diagnostic sensitivity of 33,7% compared to 22% for culture. Analysis of tissue samples gave 65 polymerase chain reaction (PCR)-positive (42.2%) and 49 culture-positive samples (31.8%). Therefore, the detection limit of the DNA-extraction is the same as previously reported for culture, the PCR assay could detect more positive samples than the culture method.
