| Abstract | We report the occurrence of the microsporidian parasite Steinhausia sp. in the oocytes of the common cockle Cerastoderma edule in a natural population in France, where high mortalities occurred. Steinhausia sp. appeared primarily as sporocysts containing many small spores, and putative earlier developmental stages were also observed. Both its prevalence and infection intensity were low, and no host defence reaction was recognized, suggesting that Steinhausia sp. had no detrimental effect on C. edule. Its prevalence was higher in cockles lying on the sediment surface, but the significance of this observation could not be explained given the poor knowledge of the Steinhausia life cycle. The present data did not allow specific identification of the parasite, and further studies are required to determine whether Steinhausia sp. in the cockle is a new species, or a microsporidian infecting multiple host species. | ||||||||
