Abstract
Six groups of ten 18-wk-old mycoplasma-free white leghorn pullets were vaccinated with one of the following: M. gallisepticum (MG) bacterin, Haemophilus gallinarum bacterin, Pasteurella multocida bacterin, combined infectious bursal disease (IBD)-Newcastle disease virus (NDV) chicken embryo origin (CEO) vaccine, IBD-NDV tissue culture origin (TC) vaccine or saline emulsified in oil; 1 group received no vaccine. Plate agglutination tests for M. synoviae (MS) and MG were done for 10 wk after vaccination using 3 test antigens. Pullets vaccinated with H. gallinarum bacterin and IBD-NDV TC vaccine showed the greatest incidence of nonspecific plate agglutination reactions. The incidence of positive plate agglutination reactions varied with test antigens. Five groups of fifty 18-wk-old mycoplasma-free heavy-breed pullets were vaccinated with one of the following: saline emulsified in oil, chickens embryo fibroblasts emulsified in oil, allantoic fluid emulsified in oil, chicken embryos emulsified in oil or MS-contaminated chicken embryos emulsified in oil. Plate agglutination tests for MS and MG were done for 8 wk after vaccination. Chickens vaccinated with chicken embryo fibroblasts emulsified in oil had the greatest incidence of nonspecific plate agglutination reactions. Pullets vaccinated with MS-contaminated chicken embryo vaccine had only a small increase in MS-positive plate agglutination reactions compared with pullets vaccinated with uncontaminated chicken embryo vaccine.
