Original Article


During March 2012 through February 2013, 100 freshwater ornamental fishes in 22 species from some aquarium fish shops were examined. Specimens were dissected and tissue samples consisted of liver, kidney, spleen, heart, intestine, ovary, brain and eye were fixed in 10 % buffered formalin and sections were provided and stained with hematoxylin and eosin, Periodic Acid-Schiff, Giemsa and acid-fast staining (Ziehl-Neelsen). At present study six species of protozoans consisting of Eimeria spp. Cryptosporidium spp., Tetrahymena corlissi, Thecamoeba spp., Giardia spp., Myxobolus spp. and two metazoan parasite consisting of Nematoda spp. and Benedenia monticelli were identified. Thecamoeba, B. monticelli and Cryptosporidium spp. were not reported in previous Iranian studies and it is the first report of infestation to this parasite in ornamental fish in Iran.
