[Composition of Eimeria in turkeys in Bulgaria].

Studied was the species composition of Eimeria in turkeys on a pedigree farm in the territory of the Higher Institute of Zootechnics and Veterinary Medicine. Metrical and morphologic investigations were carried out with more than 1000 sporulated oocysts isolated from parental flocks, turkey poults for fattening, clinically affected poults at various ages, and from experimentally infected poults. On the basis of the results obtained the following species were ascertained: Eimeria meleagridis Tyzzer, 1927; E. adenoeides Moore, Brown, 1951; E. meleagrimitis Tyzzer, 1929. Most widely spread proved the Eimeria meleagridis species (52 per cent), followed by E. adenoeides (28.4 per cent), and E. meleagrimitis (26.6 per cent).
