Histological images (A to D) and tissue imprint (E) of Haplosporidia in oysters. A to C. Developmental stages of Haplosporidium nelsoni in Crassostrea virginica from Nova Scotia, Canada. A. Plasmodia (arrows) in the connective tissue of the digestive gland between the tubules. B. Sporocysts (arrows) within the epithelium of the digestive-gland tubules. C. Spores with a prominent operculum (arrow) in the disrupted tissue of a digestive-gland tubule (courtesy of M. Maillet). D and E. Bonamia ostreae from heavily infected Ostrea edulis from France. D. Numerous B. ostreae (arrows) located within haemocytes in the connective tissue between the tubules of the digestive gland. E. Imprint of connective tissue containing many B. ostreae (arrows), some with two nuclei, freed from ruptured haemocytes. All bars = 10 µm.
