| Paratuberculosis (Johne's disease) is a chronic enteritis in cattle caused by infection with Mycobacterium avium subsp. paratuberculosis (Map). In Brazil, few reports describe the isolation of the organism. The gold standard test for Map is its isolation from tissues or feces. Moreover, bacterial growth is slow and test results are available only after three to five months of incubation Furthermore, shedding of bacilli at levels detectable by fecal culture is irregular and does not occur during the early stages of infection, which compromises the sensitivity of this methodology. The most common immunological tests to identify Map infection are complement fixation test (CFT), agar gel immunodiffusion (AGID) and enzyme-linked immunoassay (ELISA). In Brazil,... |
