BACKGROUND The aim of this study was to detect the occurrence of parasites in fish in Armand River, Chaharmahal va Bakhtyari Province regarding the importance of native fish population in the river. METHODS The occurrence of parasites was investigated in 6 native fish (Capoeta capoeta, C. damascina, C. aculeta, Barbus barbulus, B. grypus and Glyptothorax silviae) collected from the current ma...

The expression of type I membrane Fas receptors on the surface of Ichthyophthirius multifiliis (Ich) theronts and the possible association between Fas expression and theront apoptosis induced by the immune antibody was examined. Fas receptors were detected on the theront surface using fluorescein isothiocyanate-conjugated mouse monoclonal antibody against Fas. Fas-positive theronts significantl...

The objective of this research was to establish loop-mediated isothermal amplifications (LAMP) that could be used detect parasitic ciliate Ichthyophthirius multifiliis (I. multifiliis) in freshwater cyprinid fish. Primers were developed from the distinguishing fragments 18S ribosomal RNA I. and LAMP test then evaluate optimize various concentrations chemicals, time temperature. results indicate...

Channel catfish (Ictalurus punctatus) that survive infection with the parasitic ciliate Ichthyophthirius multifiliis acquire immunity to subsequent challenge and produce specific antibodies in serum that immobilize the parasite in vitro. Cellular surface protein antigens targeted by these antibodies are referred to as immobilization antigens (i-antigens). By using an immobilizing mouse monoclon...

White spot disease, caused by the parasitic ciliate Ichthyophthirius multifiliis, is a significant threat to freshwater fish farming industry worldwide, resulting in massive mortality and economic losses. Eliminating free-swimming theronts from culture environment considered crucial for control of I. multifiliis infection. It well-documented that planktonic ciliates are valuable food resources ...
