BIOTECHNOLOGY APPROACHES TO DIAGNOSIS AND CONTROL OF LIVESTOCK DISEASES

Abstract

Biotechnology-based methodologies open a wide range of new possibilities and challenges in diagnostic microbiology, thus it is strongly advised to consider these new methods and to introduce them to our various diagnostic laboratories. However, it is important to determine the exact diagnostic capacity and value of these new technologies and to what extent can these methods replace the time consuming conventional diagnostic approaches. In general, the safest way is to maintain a multidisciplinary complex of diagnostic approaches and capacities at our laboratories which provides a practical combination of advanced new and classical technologies and a properly balanced knowledge of veterinary diagnostic medicine, infection biology and epidemiology. Livestock breeding in general is continuously challenging with new strains of diseases that are virulent to therapeutic agent in our different herds. Development of technologies which enable more accurate, efficient in diagnosis, controlling resistant strains of bacteria and viruses becomes inevitable in livestock production hence to aid improvement, development (in a disease free stocks) thus, ensuring stability and profitability which are the key factors in sustainable livestock production. Implementation of increasingly complex and recent advances in molecular genetic technology to the protein detection, detection of antibodies, nucleic acid detection, virus-vectored vaccine and Nanotechnology are numbers of new developments that have proved successful rapidly across the world, particularly developed countries in exploring genome sequence in diagnosis and treatment of diseases in livestock.
