Abstract
The availability of purified Bonamia ostreae suspensions and the devel opment of an inoculation protocol enabled experimental infections with the European flat oyster, Ostrea edulis, to be carried out. Different infectious doses were tested and the kinetics of bonamiasis studied, The 50% infectious dose (ID), determined from inoculations with 10 to 10(6) B. ostreae per individual, was estimated to be 80 000 parasites for 3-year-old oysters, This 50% ID was used to screen for parasite-re sistant oysters, Preliminary results suggested that the F-1 progeny of oysters that survived previous outbreaks of bonamiasis were more resi tant to B. ostreae.
