An Abattoir Study Of Tuberculosis In A Herd Of Farmed Elk, Terry L. Whiting, Stacy V. Tessaro
An Abattoir Study Of Tuberculosis In A Herd Of Farmed Elk, Terry L. Whiting, Stacy V. Tessaro
Michigan Bovine Tuberculosis Bibliography and Database
The purpose of this study was to examine the prevalence and distribution of grossly visible lesions of tuberculosis in a herd of 344 North American elk (Cervus elaphus) depopulated during a three-month period in 1991. Abattoir inspection detected mycobacterial lesions in 134 (39.8%) of the 337 animals received for slaughter. The prevalence of lesions increased with the age of the animals. Lesions were predominantly suppurative rather than caseous, and mineralization was less evident than in tuberculous lesions in cattle. Lesions occurred predominantly -in lymph nodes, and lungs were the only organs in which mycobacterial lesions were found. The …

Status Of Bovine Tuberculosis In North America, M.A. Essey, M.A. Koller
Michigan Bovine Tuberculosis Bibliography and Database
The eradication of bovine tuberculosis from North America is in the advanced stages as Canada and the United States struggle to remove the last vestiges of the disease from the domestic livestock population. Canada realistically anticipates total eradication from the national cattle herd within the next few years. The United States must yet effectively deal with the increased tuberculosis exposure potential from imported steers and from bovine tuberculosis newly discovered in its captive cervid industry. This paper reviews the history and development of tuberculosis eradication programs in North America. The basic evolution is described from area testing to slaughter surveillance …
The Role Of A Wildlife Reservoir In The Epidemiology Of Bovine Tuberculosis, D. U. Pfeiffer
The Role Of A Wildlife Reservoir In The Epidemiology Of Bovine Tuberculosis, D. U. Pfeiffer
Michigan Bovine Tuberculosis Bibliography and Database
The objective of this project was to study the epidemiology of bovine tuberculosis in the presence of a wildlife reservoir species. Cross-sectional and longitudinal studies of possum populations with endemic bovine tuberculosis infection were analyzed. The results were used to develop a computer simulation model of the dynamics of bovine tuberculosis infection in possum populations. A case-control study of breakdowns to tuberculosis infection in cattle herds in the Central North Island of New Zealand was conducted to identify risk factors other than exposure to tuberculosis in local possum populations.
