An alternative for the preadsorption step in the paratuberculosis serodiagnosis: Mycobacterium fortuitum

چکیده
ELISAs for paratuberculosis employ a preadsorption step with Mycobacterium phlei to diminish unspecific reactions As M. fortuitum is one of the most frequent environmental mycobacteria, the purpose of this pilot study was to evaluate its use as an alternative for the preadsorption in ELISAs for paratuberculosis. Results suggest that M. fortuitum can be an alternative instead of or associated to M. phlei with comparable results (κ > 0.8) to conventional ELISAs using M. phlei as a preadsorption antigen.

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...

An enzyme-linked immunosorbent assay (ELISA) was performed for diagnosis of paratuberculosis in goats, using as antigen a protoplasmic extract (PPA-3). The test was developed on the basis of the results obtained with two serum reference pools, positive and negative respectively. To avoid day-to-day variations, dilutions of the positive serum pool were included in each plate to obtain an arbitra...
