Detection 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...
متن کاملCharacterization of IS900 loci in mycobacterium avium subsp. paratuberculosis and development of multiplex PCR typing
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...
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 کاملFate of Mycobacterium avium subsp. paratuberculosis in Swiss hard and semihard cheese manufactured from raw milk.
Raw milk was artificially contaminated with declumped cells of Mycobacterium avium subsp. paratuberculosis at a concentration of 10(4) to 10(5) CFU/ml and was used to manufacture model hard (Swiss Emmentaler) and semihard (Swiss Tisliter) cheese. Two different strains of M. avium subsp. paratuberculosis were tested, and for each strain, two model hard and semihard cheeses were produced. The sur...
متن کاملDirect 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...
