Poultry vaccines
Disease prevention by vaccination is an integral part of flock health management protocols. Active immunization using live vaccines is the current industry standard. Routinely used vaccines in chickens include MDV, NDV, IBV, and IBDV, and in turkeys NDV and HEV. Newer vaccines, including molecular recombinants in which genes of immunogenic proteins from infectious agents are inserted into a live viral vector, are also being examined for commercial use. Efforts are under way to enhance vaccine efficacy by the use of adjuvants, particularly cytokines. The vaccine delivery systems include in ovo injection, aerosol, spray, drinking water, eye drop, and wing web injection. The in ovo vaccination procedure is relatively new and at the present time it is used primarily to vaccinate broiler chickens against MDV. Birds respond to vaccines by developing humoral and cellular immune responses. There are two main types of vaccine available for poultry: live or killed.
Scientists are looking at a novel strategy to prevent the spread of pandemic avian influenza. They have developed a vaccine that protects ducks, a known natural reservoir for the virus. They reported their findings in the November 2008 issue of the Journal of Virology
Waterfowl are considered to be the natural reservoir of influenza A viruses due to the isolation of all subtypes from these hosts. Current research indicates that influenza A viruses are continuously evolving...

We all realize that diseases cost both companies and growers and they both strive to avoid the consequences of disease. Diseases can be caused by microbes (viruses, bacteria, fungi or protozoa), internal or external parasites, genetic disorders or by nutrient deficiencies. Modern poultry production methods have virtually eliminated nutrient deficiencies and are addressing genetic disorders. However, both companies and growers continue to battle against microbes and parasites. Since fewer and...

The United States is the world leader in the poultry industry, with annual profits of $50 billion; however, food pathogens threaten the industry. Scientists are especially concerned about Avian Pathogenic Escherichia coli (APEC), which caused an estimated $80 million in losses in 2002. APEC has the potential to be as harmful as E. coli O157:H7, the strain responsible for human illness and death after consumption of contaminated meat. The genetic similarity between APEC and human E. coli...

Although plants and animals began to be acquired as domesticants nearly 10,000 years ago, it has only been the last 50 years in which animals have been intensively raised for food. In 1892 Wehman wrote “Poultry, to be successful on a large scale must be kept in small colonies of about 50 birds, for many more than that number in a single house is apt to cause sickness or disease ere long among”. Given the scale and concentration of the modern poultry industry, one must ponder whence we have...

An Auburn University veterinary professor in collaboration with researchers at Vaxin Inc. of Birmingham has developed the first "in ovo," or egg-injected, vaccine to protect chickens against avian influenza, a virus threatening human health and global poultry populations.
Haroldo Toro, whose research has been published in the scientific journal Vaccine, says it would provide 100 percent protection once an outbreak's strain is determined.
"We have proven the principle, which is the major...
