In US alone, the broiler production exceeds more than 8 billion birds per year as of 1999. In this review ARS scientist and a scientist at University of Maryland review variety of methods that have been used to combat avian diseases in the commercial setting including improved farm management practices, use of antibiotic drugs, selection of disease resistant chicken strains and manipulation of the chicken immune system. Furthermore, this paper reviews the current status on the development of novel control strategies for against three major avian enteric pathogens, Eimeria, Cryptosporidium and Salmonella. This information will help poultry industry scientists to develop better control strategy for these infections. Technical Abstract: The worldwide poultry industry provides a substantial proportion of the nutritional requirement of the human population. To keep pace with the increasing demand for the high quality, low cost protein source that poultry provides, intensive rearing practices have been developed within the past few decades. A major negative consequence of these practices has been an increase in the incidence of diseases. A variety of methods have been used to combat avian diseases in the commercial setting including improved farm management practices, use of antibiotic drugs, selection of disease resistant chicken strains and manipulation of the chicken immune system. In the latter category, development of vaccines against the major avian diseases has become a priority in the poultry industry. This review will highlight recent progress in vaccine development against three major avian enteric pathogens, Eimeria, Cryptosporidium and Salmonella. |
