Veterinary vaccines against Toxoplasma gondii.
Toxoplasma gondii has a very wide intermediate host range and is thought to be able to infect all warm blooded animals. The parasite causes a spectrum of different diseases and clinical symptoms within the intermediate hosts and following infection most animals develop adaptive humoral and cell-mediated immune responses. The development of protective immunity to T. gondii following natural infe...
متن کاملCurrent status of veterinary vaccines.
The major goals of veterinary vaccines are to improve the health and welfare of companion animals, increase production of livestock in a cost-effective manner, and prevent animal-to-human transmission from both domestic animals and wildlife. These diverse aims have led to different approaches to the development of veterinary vaccines from crude but effective whole-pathogen preparations to molec...
متن کاملBiotechnology and veterinary science: production of veterinary vaccines.
The fundamental principles of genetic manipulation are explained, as are the methods of production of vaccines of veterinary importance. Specific attenuation of micro-organisms may result from genetically-engineered mutations which produce metabolic blocks, from the development of effective bacterial toxoids and from viral gene segment reassortment. Recombinant DNA techniques have been used to ...
متن کاملAdjuvants designed for veterinary and human vaccines.
Adjuvants play an important role in the efficacy of vaccines as the antigens become more and more purified. Indeed recombinant proteins or synthetic peptides are safer than crude inactivated micro-organism, but less immunogenic. This can be balanced by specific adjuvants. But there is no universal adjuvants and their action is not yet clear and rely on different mechanisms. Then, they must be a...
متن کاملCarrier molecules for use in veterinary vaccines.
The practice of immunization of animals and humans has been carried out for centuries and is generally accepted as the most cost effective and sustainable method of infectious disease control. Over the past 20 years there have been significant changes in our ability to produce antigens by conventional extraction and purification, recombinant DNA and synthesis. However, many of these products ne...
