The study aimed at direct detection of Mycobacterium avium subsp. Paratuberculosis (MAP) in milk by evaluating a multiplex real-time PCR assay targeting IS900 and ISMAV2 sequences including the amplification of PUC19-plasmid as internal control. The sensitivity of the assays was evaluated by testing MAP isolates in broad linear range of DNA (50 ng – 5 fg/μl). For the validation of the specifici...

Mycobacterium avium subsp. paratuberculosis is a robust and phenotypically versatile pathogen which causes chronic inflammation of the intestine in many species, including primates. M. avium subsp. paratuberculosis infection is widespread in domestic livestock and is present in retail pasteurized cows' milk in the United Kingdom and, potentially, elsewhere. Water supplies are also at risk. The ...

Five pigmented isolates of Mycobacterium avium subsp. paratuberculosis were examined by pulsed-field gel electrophoresis (PFGE), IS900 restriction fragment length polymorphism (IS900-RFLP), and IS1311 polymorphism analysis using PCR. All of the pigmented isolates exhibited one of three distinct PFGE profiles with SnaBI, designated 9, 10, and 11, and with SpeI, designated 7, 8, and 9, which gene...

A triplex real-time (TRT-PCR) assay was developed to ensure a rapid and reliable detection of Mycobacterium avium subsp. paratuberculosis (Map) in faecal samples and to allow routine detection of Map in farmed livestock and wildlife species. The TRT-PCR assay was designed using IS900, ISMAP02 and f57 molecular targets. Specificity of TRT-PCR was first confirmed on a panel of control mycobacteri...

Mycobacterium avium subsp. paratuberculosis is a pathogen that causes chronic inflammation of the intestine in many animals, including primates, and is implicated in Crohn's disease in humans. It differs from other members of the M. avium complex in having 14-18 copies of IS900 inserted into conserved loci in its genome. In the present study, genomic DNA flanking 14 of these insertions was char...

The efficacy of bacterial cultures and IS900-specific polymerase chain reaction (PCR) was compared for the detection of Mycobacterium avium subsp. paratuberculosis (MAP) from the mesenteric lymph nodes of goats. Samples were collected from 75 goats slaughtered in Ilam, in southwest of Iran. Tissue homogenates were inoculated onto four media. The genomic DNA was extracted directly from mesenteri...

Mycobacterium avium subsp. paratuberculosis is the etiologic agent of Johne's disease and is endemic to the national cattle herds of many countries. Because of the very low level of genetic heterogeneity of this organism, it is difficult to select a workable procedure for strain differentiation at a resolution sufficient to investigate epidemiological links between herds or different ruminant s...

BACKGROUND Mycobacterium avium subspecies paratuberculosis (MAP) is the causative agent of Johne's disease (JD), or paratuberculosis in ruminants has been suspected to be implicated in the pathogenesis of Crohn's disease (CD) in humans with chronic inflammatory intestinal changes. As the hypothesis is now fast being recognized that MAP could possibly be the etiological agent of CD which is foun...
