Despite traditional disease control measures, losses attributable to infectious diseases continue to impede the livestock industries. An alternative approach to this problem is genetic disease resistance involving both immune and non-immune mechanisms, which is the inherent capacity of a previously unexposed animal to resist disease when challenged by pathogens. Although the nurturing environme...

The potential contributions of techniques, such as restriction enzyme analysis, nucleic acid detection, the polymerase chain reaction and competitive inhibitive tests, are only beginning to be defined. The extraordinary promise of these procedures has yet to be fully realized. However, before these techniques are accepted and widely used, they should be shown to have sensitivity and specificity...

The most important aerobic bacterial diseases of farmed deer and bison include bovine tuberculosis, Johne's disease (paratuberculosis), yersiniosis, leptospirosis, brucellosis, pasteurellosis, anthrax, salmonellosis and colibacillosis. Anaerobic bacterial infections affecting the same animals include necrobacillosis and a number of clostridial diseases such as tetanus, blackleg, malignant oedem...

Periodontitis is one of the most complex infectious diseases of the human body. Individual periodontal lesions may harbor millions of genomic copies of herpesviruses (179) as well as papillomaviruses, human immunodeficiency virus (HIV), human T-lymphotropic virus type 1, torquetenovirus, and hepatitis B and C viruses (190). Herpesvirus-infected periodontal sites tend to exhibit more breakdown t...

International Circumpolar Surveillance (ICS) is a population-based invasive bacterial disease surveillance network. Participating Canadian regions include Yukon, Northwest Territories, Nunavut, and northern regions of Québec and Labrador (total population 132,956, 59% aboriginal). Clinical and demographic information were collected by using standardized surveillance forms. Bacterial isolates we...
