VS - Bovine Tuberculosis (Mycobacterium bovis) Surveillance Standards 11/2001

Bovine tuberculosis (TB) is an infectious and communicable granulomatous disease caused by the acidfast bacilli bacteria of Mycobacterium bovis (M. bovis). It is commonly a chronic, debilitating disease, but occasionally may assume an acute, rapidly progressive course. M. bovisis a widespread zoonosis that is global in magnitude and affects nearly all species of vertebrates (cattle, sheep, goats, pigs, bison, buffalo, and camelids.) Disease is spread by direct contact, inhalation of infected droplets expelled from infected lungs, and ingestion of contaminated feed or milk. In most countries, TB is a notifiable disease. Overall, TB has an important world-wide impact on animal industries and human health. Control measures are based on prevention and eradication. Surveillance is a key element for management of preventions and control programs. Surveillance for TB serves the purpose of enabling Veterinary Services to obtain an accurate picture of the scope of the disease in the US livestock populations; in the event of a disease outbreak, the course TB follows in livestock and wildlife populations for a given area over time; and permits timely intervention if the trend observed deviates from what is expected.

Master Conservationist Presentations - 2001

We begin the 2001 Master Conservationist program with honorees in production agriculture from District A which includes the Panhandle of Nebraska. I would like to ask Leon and Cheryl Burkhart-Kriesel (Kresel) of Gurley who are unable to be present. They operated the family farm in partnership with Fred and Viola Kriesel until 1984 when Leon and Cheryl become sole owners/operators. The Kriesels produce certified wheat, millet, oats, and barley seed on 3200 dryland acres that are owned, rented, or contracted. Since 1984, 45,000 feet of terraces have been installed. Their holistic conservation plan also includes over 57,000 feet of windbreaks of mixed evergreen and broadleaf trees and shrubs. This mixture of plant species is unique in the Panhandle. They built an earthen dam with 11 acre-feet of permanent storage and 70.5 acre-feet of detention storage. Results include reduced soil erosion by wind and water, and increased productivity and wildlife populations. Local and international groups tour the farm. Congratulations to the Kriesels.
