Copper sulfate toxicity to two isolates of Ichthyophthirius multifiliis relative to alkalinity

Antibody binding following exposure of live Ichthyophthirius multifiliis (Ciliophora) to serum from immune carp Cyprinus carpio

Trophont stages of the c~l ia te fish parasite Ichthyophtl~jrius n~ult i f i l i is were Incubated alive in vitro in serum from immune carp Cyprinus carpi0 and subsequently examined immunoh~stoloyically for bound ant~body. Parasites became immobilized in immune serum and were enveloped by gelatinous mucus-llke material. Carp antibody could not be detected bound to cilia membranes (the major sur...

Enhanced susceptibility of channel catfish to the bacterium Edwardsiella ictaluri after parasitism by Ichthyophthirius multifiliis.

Bacterium Edwardsiella ictaluri and parasite Ichthyophthirius multifiliis (Ich) are two common pathogens of cultured fish. The objective of this study was to evaluate the susceptibility of channel catfish Ictalurus punctatus to E. ictaluri and determine bacterial loads in different fish organs after parasitism by Ich. Fish received the following treatments: (1) infected by I. multifiliis at 500...

Susceptibility of channel catfish, blue catfish and channel×blue catfish hybrid to Ichthyophthirius multifiliis

Susceptibility of three strains of blue catfish, Ictalurus furcatus (Valenciennes), to Ichthyophthirius multifiliis.

This study compared the susceptibility of three blue catfish strains (D&B, USDA 101 and USDA 102) to the parasite Ichthyophthirius multifiliis (Ich). In Trial I, a cohabitation study (all strains stocked communally) was conducted and fish were exposed to theronts at 0, 200, 1000, 5000 or 25 000 theronts fish(-1), respectively. All fish died when exposed to theronts at 5000 or 25 000 theronts fi...
