Abstract

In this study, a controlled experimental infection of Veiltail aquarium fish with I.multifilis has been carried out. Chemical treatment using commercial formalin, methylene blue and sodium chloride at suitable doses and time of exposure, have been used to treat the infected fish. Also the physical treatment through rising of water temperature to 25°C and 30°C with partial of full water change have been tried with great success. The protective immunity as expressed by the parasitic burden on challenged fish and mortality percent was proved in Veiltail fish that were exposed to primary high dose of infection followed by chemical or physical treatments and finally challenged with the same primary infective dose.
