Extract

Judged by oocyst production, infections with Eimeria acervulina in birds immunized with E. maxima were consistently higher than in birds which had not been immunized. Oocyst production of E. maxima in birds previously infected with E. acervulina was greater, in three out of four experiments, than in control chickens, but some of the differences were slight. The findings are discussed but no satisfactory explanation can be offered. In general there was little or no difference between the oocyst production of the individual species when present as single or mixed infections.
