Characterization 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 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...
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...
متن کاملDifferential responses of bovine macrophages to Mycobacterium avium subsp. paratuberculosis and Mycobacterium avium subsp. avium.
Mycobacterium avium subsp. paratuberculosis and Mycobacterium avium subsp. avium are antigenically and genetically similar organisms; however, they differ in their virulence for cattle. M. avium subsp. paratuberculosis causes a chronic intestinal infection leading to a chronic wasting disease termed paratuberculosis or Johne's disease, whereas M. avium subsp. avium causes only a transient infec...
متن کاملNew variable-number tandem-repeat markers for typing Mycobacterium avium subsp. paratuberculosis and M. avium strains: comparison with IS900 and IS1245 restriction fragment length polymorphism typing.
Mycobacterium avium subsp. paratuberculosis, the etiological agent of paratuberculosis, affects a wide range of domestic ruminants and has been suggested to be involved in Crohn's disease in humans. Most available methods for identifying and differentiating strains of this difficult species are technically demanding and have limited discriminatory power. Here, we report the identification of no...
