| 摘要 |
An antigen composition for stimulating an immune response in an inoculated avian species to at least one intestinal pathogenic organism includes seven field strains of E. coli, Pseudomona aeruginosa, Aerobacter aerogenes, Salmonella enteritidis, Salmonella typhimurium, Salmonella agona, and Salmonella Kentucky. The antigen composition can be used alone or in combination with a Marek's Disease vaccine to reduce shedding of E. coli and/or Salmonella bacteria.
