Brooklynella hostilis explained

Brooklynella hostilis is a parasite of marine fish, found in wild fish, farmed fish and aquariums.[1] It is kidney-bean shaped, and approximately 60–80 μm long,[1] with bands of cilia. B. hostilis is the only species in the monotypic taxon Brooklynella, a genus in the order Hartmannulidae. It reproduces by binary fission.

B. hostilis causes the disease Brooklynellosis, also known as slime-blotch or clownfish disease.[2] In marine aquariums, B.hostilis infects most teleosts (ray finned fishes).[3] B.hostilis feeds on dead skin cells and can cause severe damage to gills.[4] Affected fish have a gray discoloration, and may breathe abnormally fast or abnormally slow.[5] The infection can cause sloughing of skin, and congestion of the gills.[6] The parasite spreads rapidly, and can easily transfer to a new host.[7] Formalin is an effective treatment.[5]
