[ 1 ] - Comparison of microscopy and blood-PCR for the diagnosis of clinical Johne’s disease in domestic ruminants

Microscopy as “field based test” was compared with IS900 blood PCR for the diagnosis and estimationof prevalence of Mycobacterium avium subspecies paratuberculosis (MAP) in domestic livestock withclinical Johne’s disease (JD). Of 252 animals screened, 39.3 and 13.1% were positive by faecal microscopyand blood PCR, respectively. Proportional agreement between “microscopy” and blood PCR was subst...

[ 2 ] - Cloning and characterization of MAP2191 gene, a mammalian cell entry antigen of Mycobacterium avium subspecies paratuberculosis

The aim of this study is to identify, clone and express a Mycobacterium avium subsp. paratuberculosis specific immunogenic antigen candidate, in order to develop better reagents for diagnosis and vaccines for the protection of the host. Therefore, MAP2191 gene (a member of MAPmce5 operon) from MAP, was isolated and characterized by Bioinformatics tools and <e...
