TL;DR: A need for revision in the taxonomy and assessment of the zoonotic potential of some animal C. parvum isolates is indicated, because extensive genetic diversities were present among C. Parvum genotypes.

TL;DR: A high degree of genetic similarity between M. paratuberculosis strains recovered from cows regardless of geographic origin is identified, and the results of analyses reveal a relatively higher degree of Genetic heterogeneity among M. avium subsp.

TL;DR: Sensitivity and specificity of a new ELISA for antibodies against Mycobacterium avium subsp paratuberculosis agreed favorably with those of a previous ELISA and practitioners must be aware of variability in the sensitivity of the test, which depends on the clinical and shedding status of the cattle.

TL;DR: The data indicate that liquid culture followed by molecular confirmation can significantly improve sensitivity and reduce time-to-diagnosis (from 16 to 8 weeks) of M. paratuberculosis infection and can also be efficiently employed for the systematic differentiation ofM.

TL;DR: In this paper, a broth-based automated system was used for cultivation of mycobacteria such as M. paratuberculosis from human hosts, for the detection of the organism in bovine feces.
