Imidazole in organs of inbred chickens selected for resistance or susceptibility to lymphoid leukosis or Marek's disease.
Total and soluble imidazole was determined on samples of liver and kidney and soluble imidazole was determined on blood from eight strains of chickens selected at three locations for resistance or susceptibility to lymphoid leukosis and/or Marek's disease. Liver and kidney total and soluble imidazole was not different between strains classed as resistant or susceptible to lymphoid leukosis and/or Marek's disease. The weighted average of soluble blood imidazole was higher (P smaller than 0.01) in strains classed as resistant to lymphoid leukosis. A similar difference (P smaller than 0.01) was observed with strains classed as resistant or susceptible to Marek's disease when the selections from one location were not included in the weighted average.
