With the objective of identifying presence Paratuberculosis (PTB), an infectious disease caused by Mycobacterium avium ssp paratuberculosis (MAP), in sheep, through pathological studies, bacterial culture and IS900 PCR, as well estimating seroprevalence to MAP. The present cross-sectional study, was conducted 16 different flocks, with serum 2415 adult sheeps, analyzed Enzyme-Linked ImmunoSorben...

Mycobacterium avium subsp. paratuberculosis causes Johne's disease, a systemic infection and chronic inflammation of the intestine that affects many species, including primates. Infection is widespread in livestock, and human populations are exposed. Johne's disease is associated with immune dysregulation, with involvement of the enteric nervous system overlapping with features of irritable bow...

BACKGROUND Mycobacteria, such as M. leprae and M. tuberculosis infect billions of humans. However, because of appropriate immune responses and antibiotic therapy, overt mycobacterial diseases occur far less frequently. M. avium subspecies paratuberculosis (MAP) causes Johne's disease in ruminants, an affliction evocative of inflammatory bowel disease (IBD). Several agents used to treat IBD (5-A...

Mycobacterial isolates were obtained by radiometric culture from 33 different species of captive or free-ranging animals (n = 106) and environmental sources (n = 3) from six geographic zones within the United States. The identities of all 109 isolates were confirmed by using mycobactin J dependence and characterization of five well-defined molecular markers, including two integration loci of IS...
