Differentiation of species of Eimeria from the fowl using a computerized image-analysis system.

Oocysts of Eimeria species from the fowl have been identified using a computerized image-analysis system (Leitz T.A.S. Plus Image-Analyser). The system enabled semiautomatic measurement of oocyst dimensions with subsequent species of diagnosis based on graphic statistical evaluation of size and shape of measured parasites. E. mitis, E. acervulina, E. brunetti, E. maxima, E. tenella and complex of E. necatrix and E. praecox were distinguishable both in pure cultures and in mixtures. It was not possible to distinguish E. praecox from E. necatrix using this system.
