Abstract:

Four of 50 sea cucumbers, Holothuria floridana, from the Florida Key were infected with a new species of gregarine protozoan parasite. Gonospora holoflora n.sp. has pyriform gamonts up to 400 μm long, slightly ovoid gamerocysts 125 μm by 150 μm, and oval oocysts 7 μm by 11 μm without tails. The parasite remains attached to the coelom-side of the holothuroid intestine at least until the terminal stage cyst is reached. The holothuroid exhibited a coelomocyte reaction to the parasitic infection producing numerous lymphocytes that covered the coelom-side of the intestine.
