Diversity and Universality of Endosymbiotic Rickettsia in the Fish Parasite Ichthyophthirius multifiliis
Although the presence of endosymbiotic rickettsial bacteria, specifically Candidatus Megaira, has been reported in diverse habitats and a wide range of eukaryotic hosts, it remains unclear how broadly Ca. Megaira are distributed in a single host species. In this study we seek to address whether Ca. Megaira are present in most, if not all isolates, of the parasitic ciliate Ichthyophthirius multi...
متن کاملAntibody 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...
متن کاملIchthyophthirius multifiliis as a potential vector of Edwardsiella ictaluri in channel catfish.
There is limited information on whether parasites act as vectors to transmit bacteria in fish. In this trial, we used Ichthyophthirius multifiliis and fluorescent Edwardsiella ictaluri as a model to study the interaction between parasite, bacterium, and fish. The percentage (23-39%) of theronts fluorescing after exposure to E. ictaluri was significantly higher than control theronts (~ 6%) using...
متن کاملSystemic and cutaneous mucus antibody responses of channel catfish immunized against the protozoan parasite Ichthyophthirius multifiliis.
Fish acquire protective immunity against the ciliated protozoan parasite Ichthyophthirius multifiliis following sublethal infection or inoculation with I. multifiliis immobilization antigens (i-antigens). In both cases, parasite-immobilizing antibodies have been identified in sera and mucosal secretions. To investigate the kinetics of this immune response, antibody levels were determined by enz...
متن کاملProtective immunity of Nile tilapia against Ichthyophthirius multifiliis post-immunization with live theronts and sonicated trophonts.
Two immunization trials were conducted to evaluate host protection of Nile tilapia, Oreochromis niloticus against Ichthyophthirius multifiliis (Ich). Immunizations were done with live theronts or sonicated trophonts by bath immersion and intraperitoneal (IP) injection. The immunized fish were challenged with theronts 21 days post-immunization in trial I and 180 days post-immunization in trial I...
