Abstract

Individuals of the clam Mytella guyanensis (Bivalvia: Mytilidae) from the estuarine region of the Cachoeira river (Ilhéus, Bahia) have been analyzed to detect the frequency of occurrence and infected sites by protozoans of the genus Nematopsis Schneider, 1892 (Apicomplexa: Eugregarinida: Porosporidae), in the period between August 2005 and May 2006. A total of 480 individuals were analyzed, measuring between 34.5 and 74.9 mm of height (Average: 55.4 mm; DP ± 6.7). Nematopsis were found in 387 of them, occurring more frequently within the gills (298 animals) and the mantle (248). The parasite was also observed in the digestive gland and the musculature. Some severely infected individuals presented modifications in the conformation of the gills and the mantle.
