Direct detection of Mycobacterium avium subsp. Paratuberculosis in bovine milk by multiplex Real-time PCR
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...
متن کاملComparison of Two Immunomagnetic Separation Methods for Detection of Mycobacterium avium subsp. Paratuberculosis in Bovine Feces
Detection of Mycobacterium paratuber culosis in feces is complicated by the slowdivision and the lipid composition of the cell wall of the bacterium. In this study, we compared a rapid and sensitive method for direct detection of M. paratuberculosis with anti-paratuberculosis chicken IgY-conjugated magnetic nanoparticles versus commercially available micro-sized paramagnetic beads. Tenfold seri...
متن کاملRapid real-time PCR assay for detection and quantitation of Mycobacterium avium subsp. paratuberculosis DNA in artificially contaminated milk.
Using fluorescence resonance energy transfer technology and Lightcycler analysis, we developed a real-time PCR assay with primers and probes designed by using IS900 which allowed rapid detection of Mycobacterium avium subsp. paratuberculosis DNA in artificially contaminated milk. Initially, the PCR parameters (including primer and probe levels, assay volume, Mg(2+) concentration, and annealing ...
متن کاملAutomated high-throughput immunomagnetic separation-PCR for detection of Mycobacterium avium subsp. paratuberculosis in bovine milk.
Two monoclonal antibody-mediated immunomagnetic separation PCR kits (AnDiaTec ParaTub-S IMS-PCR-ELISA and ParaTub-SL IMS-real time PCR) were developed and evaluated for the automated high-throughput detection of Mycobacterium avium subsp. paratuberculosis (M. paratuberculosis) in bulk milk of naturally infected dairy herds and made commercially available. M. paratuberculosis are first isolated ...
متن کاملDetection of Mycobacterium avium subsp. paratuberculosis in Cow Milk Using Culture and PCR methods
Mycobacterium avium subspecies paratuberculosis (MAP) is the cause of John’s disease also called paratuberculosis. This is economically one of the important infectious diseases in cattle and ruminant husbandry. This disease is manifested as granulomatosis entrocolitis, lymphadenitis and inflammation local lymphatic vessels. The typical sign of this disease is progressive loss of weight. Cons...
