Identification of seven Eimeria species in Swedish domestic fowl

The aim of the study, conducted during the period 1992 to 1996, was to iden tify the Eimeria species present in Swedish chickens, All samples, includin g titter, faeces and guts from dead birds submitted for coccidial diagnosis , were obtained from farms where no live coccidiosis vaccines had ever been used, Identification of the different species was based on the criteria of oocyst morphology, location and characteristics of intestinal lesions, mor phology of parasite endogenous stages, prepatent time and isoenzyme electro phoresis profiles of glucose phosphate isomerase, All seven Eimeria species of the domestic fowl were identified, namely E. acervulina, E. brunetti, E . maxima, E. mitis, E. necatrix, E. praecox and E. tenella, Furthermore, Sw edish monospecific isolates of E, maxima, E, necatrix and E, tenella were e stablished.
