also known as: Glossatella
Apisoma are ciliated Protozoans, known previously as Gloassatella. They are sessile and attach to the skin, gills and fins of fish living in infested environment. The organisms are visible under the microscope as vase-shaped parasites on body surfaces. They are found commonly in ponds only and affect ornamental or marine fish rarely. Symptoms include decreased appetite, flashing, hyperplasia of infested gill tissues, compromised osmoregulation and respiration. Poor water quality and high fish stocking densitites are factors when it comes to the parasite’s impact on the population. Treatment, particularly of heavily infestated ponds is recommended using one of the following: formalin, copper sulfate, potassium permanganate, or a salt dip. This bacterium can not infect humans.
