The nematode Caenorhabditis elegans has become a model system for studying the disease interaction between pathogens and the host. To determine whether the transparent nematode could serve as a useful model for Mycobacterium avium subspecies hominissuis (MAH) infection of the intestinal tract, worms were fed MAH and assayed for the...
Understanding the pathogenic mechanisms of Mycobacterium avium subspecies paratuberculosis (MAP) and the host responses to Johne's disease is complicated by the multi-faceted disease progression, late-onset host reaction and the lack of available ex vivo infection models. We describe a novel cell culture passage model that mimics the course of infection...
Johne's disease, caused by Mycobacterium avium subspecies paratuberculosis (MAP), is a severe chronic enteritis which affects large populations of ruminants globally. Prevention strategies to combat the spread of Johne's disease among cattle herds involve adhering to strict calving practices to ensure young susceptible animals do not come in contact with...
Mycobacterium avium subspecies paratuberculosis (MAP) is the causative agent of Johne's disease, a chronic inflammatory bowel disease that affects ruminant populations worldwide. The characteristic stages of the disease make diagnosis difficult, resulting in silent transmission among animals in a herd for years before proper detection of the infection. The extensive...
Johne’s disease is caused by Mycobacterium avium subsp. paratuberculosis (MAP), which results in serious economic losses worldwide in farmed livestock such as cattle, sheep, and goats. To control this disease, an effective vaccine with minimal adverse effects is needed. In order to identify a live vaccine for Johne’s disease, we...
