The effect of Perkinsus
olseni infection on clam reproduction.
Villanueva-Fonseca & Escobedo-Bonilla (2013) evaluated the presence of Perkinsus
Spawned oysters were removed from individual cups, and shell height (mm), dry tissue weight (g), and Perkinsus
marinus (dermo) infection intensity were determined for each female.
According to the Office International des Epizooties (OIE), two species of the phylum Perkinsozoa, Perkinsus
marinus and Perkinsus
olseni, are notifiable (OIE, 2012) due to the substantial mortality rates and economic losses with which they are associated around the world (Villalba et al.

By 2006, this 54-yr record covered a number of unique periods, including the period of time after the onset of MSX, a disease caused by the protozoan Haplosporidium nelsoni, circa 1957 (Haskin and Andrews, 1988; Ford, 1997) and the period after the onset of Dermo, a disease caused by the protozoan Perkinsus
marinus, circa 1990 (Ford, 1996; Cook et al.
