Immune responses of red deer (Cervus elaphus) that presented with different levels of paucibacillary pathology were profiled to detail immune changes during the progression of Johne's disease. Immune responses were monitored using an immunoglobulin G1 (IgG1) antibody enzyme-linked immunosorbent assay (ELISA), a gamma interferon (IFN-gamma) ELISA, and flow(More)
Paratuberculosis progresses more quickly in young red deer than in sheep or cattle. This study describes the clinical, immunological and pathological changes over a 50-week period in fourteen 4-month-old red deer that received heavy oral challenge with Mycobacterium avium subsp. paratuberculosis (MAP). At 4 and 12 weeks post challenge they were(More)
BACKGROUND In the absence of overt clinical signs of Johne's Disease (JD), laboratory based tests have largely been limited to organism detection via faecal culture or PCR and serological tests for antibody reactivity. In this study we describe the application of quantitative faecal PCR for the detection of Mycobacterium avium subsp. paratuberculosis (MAP)(More)
Although most studies in immunology have used inbred mice as the experimental model to study fundamental immune mechanisms they have been proven to be limited in their ability to chart complex functional immune pathways, such as are seen in outbred populations of humans or animals. Translation of the findings from inbred mouse studies into practical(More)
This report describes how Mycobacterium bovis infection was controlled and eventually eradicated in a farmed red deer herd in the north of England, following sustained tuberculin skin testing supplemented with serological (antibody) tests over a period of approximately two years. By taking advantage of the anamnestic antibody response produced by the skin(More)
