[Studies on coccidia of geese in the south-west region of France. Proposed key for the classification differentiation of different species based on the morphology of the sporulated oocyst].

Eight coccidian species found in the domestic goose (Anser anser domesticus) in the south-west of France are described. An identification key based on the morphological features of sporulated oocysts is proposed. Of the eight species, two had not, previously, been reported in domestic geese; one of them might be a new species.
