Abstract

Mycobacterium paratuberculosis, Johne's disease (JD), is a chronic. incurable enteropathy affecting cattle and other ruminants. Both diagnostic and control measures have been inadequate to enable early detection and elimination of the infection from cattle herds.

This study attempts to develop and evaluate diagnostic methods and to correlate management and disease control practices with reduction in prevalence of JD-infected animals from known JD-positive herds.

A small farm is nestled among rolling hills, fields stretching across a curving road that disappears between dark green trees. The barn is a cheery red color with a tin roof. Beneath the photo is the a statement of the conference's theme in white italics: Challenges of the Bovine Industry in the Twenty-First Century. Deep red background.
