The chronic pattern of disease, complexity of its path biology, limitations knowledge’s on pathogenesis, poor sensitivity and specificity of currently available laboratory diagnostic methods, lack of successful vaccines,  make Johne’s disease control a significant challenge for veterinary services and scientific community as well. This paper aim to highlight the current achievements on path-biology, diagnosis, biosecurity,  in order to translate them in practical action for Johne’s disease control.
