The article by Thoresen and Saxegaard (7) concerning the relationship between Mycobacterium avium and Mycobacterium paratuberculosis as determined by using the GenProbe Rapid Diagnostic System contains interesting observations, some of which are not unexpected. Because M. paratuberculosis is rather inactive biochemically and because of variability between strains, biochemical reactions appear t...

Paratuberculosis is an infectious-contagious disease caused by the bacterium Mycobacterium avium subspecie paratuberculosis (MAP), which affects digestive tract of ruminants. MAP distributed worldwide; however, there are no publications on seroprevalence this in cattle state Sonora. Therefore, objective study was to detect seropositivity Sonora, as well know its apparent prevalence a population...

During DNA sequence analysis of cosmid L373 from the Mycobacterium leprae genome, an open reading frame of 1.4 kb encoding a protein with some homology to the immunodominant 34-kDa protein of Mycobacterium paratuberculosis, but lacking significant serological activity, was detected. The DNA sequence predicted a signal peptide with a modified lipoprotein consensus sequence, but the protein prove...

Paratuberculosis (Johne‟s disease) is widely distributed throughout the world and is caused by Mycobacterium avium subspecies paratuberculosis (MAP) (Baumgartner and Johnannes, 2008). The disease mainly affects domestic and wild ruminants (Chiodini et al., 1984) but MAP can also be found in numerous monogastric animals (Klee, 2002). Johne‟s disease (JD) characterized by emaciation, progressive ...

Mycobacterium avium subspecies paratuberculosis (MAP) causes Johne's disease or paratuberculosis, a gastro intestinal inflammatory condition in ruminants and other animals, which is similar to Crohn's disease (CD) that occurs in man. The role of MAP in the causation of CD has been under intense investigation in the last few decades. This review summarizes the status of MAP in animals and the fo...

Mycobacterium avium subsp. paratuberculosis (M. paratuberculosis) the causative agent of Johne's disease, is one of the most serious infectious diseases in dairy cattle worldwide. Due to the chronic nature of this disease and no feasible control strategy, it is essential to have an efficient animal model which is representative of the natural route of infection as well as a viable treatment opt...

The prevalence of Escherichia coli, Salmonella spp., and Mycobacterium avium subsp. paratuberculosis isolated from the feces of wild European starlings (Sturnus vulgaris) humanely trapped at a feedlot in central Kansas was assessed. All E. coli and Salmonella isolates recovered were tested for antimicrobial susceptibility using National Antimicrobial Resistance Monitoring System panels and the ...

Mycobacterium paratuberculosis, an acid-fast bacillus that causes enteritis in ruminants, has been suggested as an etiological agent of Crohn's disease in humans. The mode of transmission is unclear; however, some evidence suggests that humans may become infected via contaminated milk. Currently, it is not known whether commercial pasteurization effectively kills M. paratuberculosis in contamin...

OBJECTIVE To estimate the prevalence of Mycobacterium avium subsp paratuberculosis infection among cows on beef operations in the United States. DESIGN Cross-sectional seroprevalence study. Sample Population-A convenience sample of 380 herds in 21 states. PROCEDURES Serum samples were obtained from 10,371 cows and tested for antibodies to M avium subsp paratuberculosis with a commercial ELI...
