Extract

The life cycle and pathogenicity of a strain of Eimeria isolated in Great Britain from turkey poults by single cell inoculation are described and, using the criteria laid down by Tyzzer, the species is identified as E. adenoeides.

The life cycle is of the same general pattern as in other Eimeria species, consisting of two asexual and one sexual generations.

The organism is highly pathogenic for young poults, a dose of 200,000 oocysts producing 100 % mortality in 3-week-old birds and smaller doses causing reduced weight gain. Birds 11 weeks old resisted a dose of 3 million oocysts.

The gross and microscopic pathology of the infection is described. No changes were found in the blood picture.
