BACKGROUND Mycobacterium avium subspecies paratuberculosis causes systemic infection and chronic intestinal inflammation in many species including primates. Humans are exposed through milk and from sources of environmental contamination. Hitherto, the only vaccines available against Mycobacterium avium subspecies paratuberculosis have been limited to veterinary use and comprised attenuated or k...

Lanes 9 and 10, Control subjects without type 1 diabetes mellitus. Lanes 11 and 12, Mycobacterium avium subspecies paratuberculosis–positive and M. avium subspecies paratuberculosis–negative control subjects, respectively. M, molecular mar...

Typing of Mycobacterium avium subspecies paratuberculosis strains presents a challenge, since they are genetically monomorphic and traditional molecular techniques have limited discriminatory power. The recent advances and availability of whole-genome sequencing have extended possibilities for the characterization of Mycobacterium avium subspecies paratuberculosis, and whole-genome sequencing c...

The purpose of this paper is to present and update the longitudinal perspective of the Mycobacterium avium subspecies paratuberculosis dilemma as initially stated in Infectious Diseases Incorporated’s 2012 White Paper. In both wild and domestic herbivores, Mycobacterium avium subspecies paratuberculosis (MAP) produces chronic granulomatous enteritis (Johne’s disease) that, if unchecked, is usua...

Mycobacterium avium subspecies paratuberculosis is the causative agent of Johne's disease, a chronic enteritis in ruminants. A gene homologous to that of 35-kDa antigen of Mycobacterium leprae was cloned and sequenced from Mycobacterium paratuberculosis. The database searches revealed 82.79% and 95.67% similarities of its nucleotide sequence, with those of immunodominant 35-kDa protein of M. le...

BACKGROUND Rabbits are susceptible to infection by different species of the genus Mycobacterium. Particularly, development of specific lesions and isolation of Mycobacterium avium subsp. avium and Mycobacterium avium subsp. paratuberculosis, both subspecies of the M. avium complex, has been reported in wildlife conditions. Although, rabbit meat production worldwide is 200 million tons per year,...

Antigens characteristic for Mycobacterium avium subspecies paratuberculosis were identified by crossed immunoelectrophoresis (CIE) and by absorbing out cross-reactive antigens by using a polyclonal and polyvalent Mycobacterium avium subspecies avium antiserum. Two antigens were present in M. avium subsp. paratuberculosis and not detected in Mycobacterium avium subsp. avium. They were identified...

Mycobacterium avium subsp. paratuberculosis causes paratuberculosis, a chronic granulomatous enteritis. Detecting animals with paratuberculosis infections is difficult because the currently available tools have low sensitivity and lack specificity; these tools are prone to generating spurious positive test results caused by exposure to environmental M. avium complex organisms. To generate candi...
