Diagnosis and Control of Johne's Disease

Diagnosis and Control of Johne’s Disease

Prepared by the Committee on Diagnosis and Control of Johne’s Disease and the National Research Council, this report examines Johne’s disease, a chronic intestinal infection primarily affecting ruminants. It reviews diagnostic approaches, disease transmission, and strategies to control infection and reduce its impact on livestock. The book also identifies research gaps and explores questions surrounding the possible relationship between Mycobacterium avium subsp. paratuberculosis and Crohn’s disease in humans.

Key Features:

• Explains the causes and progression of Johne’s disease
• Examines the biology of Mycobacterium avium subsp. paratuberculosis
• Discusses disease transmission among ruminants
• Reviews diagnostic methods for detecting infection
• Outlines strategies for controlling Johne’s disease
• Explores approaches to reducing infection spread within herds
• Examines the effects of the disease on livestock health
• Identifies limitations in existing research and control programs
• Recommends priorities for future scientific investigation
• Reviews research into the possible association with Crohn’s disease
