| immunization of cultured juvenile rockfish sebastes schlegeli against microcotyle sebastis (monogenea). | to determine whether immunization with microcotyle sebastis antigen could induce protection against the parasite's establishment, naive juvenile rockfish were immunized by injection or immersion with whole worm antigen of m. sebastis. the infestation intensities of immunized groups following a challenge (2 wk after boosting) with 5000 m. sebastis eyed-eggs were significantly lower than those of control groups, when determined 7 wk postinfection. the fish in the groups boosted with m. sebastis an ... | 2000 | 10785860 |
| treatment of microcotyle sebastis (monogenea: polyopisthocotylea) infestation with praziquantel in an experimental cage simulating commercial rockfish sebastes schlegeli culture conditions. | the antiparasitic efficacy of praziquantel against the blood-sucking polyopisthocotylean microcotyle sebastis was tested in an experimental cage simulating commercial rockfish-culture conditions. juvenile rockfish sebastes schlegeli were separated into 4 pilot net-pens, and the fish in the groups were either fed a control diet (group c), fed a praziquantel-adsorbed diet (group f), bathed in 100 ppm praziquantel for 4 min (group b), or bathed in 100 ppm praziquantel for 4 min and then fed a prazi ... | 2000 | 10843562 |
| treatment of microcotyle sebastis infestation in cultured rockfish sebastes schlegeli by oral administration of praziquantel in combination with cimetidine. | the effect of cimetidine on the treatment efficacy of praziquantel against microcotyle sebastis infestation in cultured rockfish sebastes schlegeli was investigated. juvenile rockfish were divided into 7 groups, and orally administered praziquantel alone (50, 100 and 200 mg kg(-1) body wt, bw) or in combination with cimetidine at a dose of 200 mg kg(-1) bw for each praziquantel dose. the fish in the control group were administered only saline. the results clearly showed that coadministration of ... | 2001 | 11324814 |
| cimetidine enhances the plasma praziquantel concentration and treatment efficacy against microcotyle sebastis in cultured rockfish sebastes schlegeli. | the effect of cimetidine on the praziquantel concentration in the blood of the rockfish sebastes schlegeli and the consequent effect on the treatment efficacy against microcotyle sebastis were investigated. fish were divided into 7 groups and orally administered praziquantel alone (200 and 100 mg kg(-1) body weight [bw]) or in combination with cimetidine (in doses of 200, 100 or 50 mg kg(-1) bw cimetidine with a praziquantel dose of 100 mg kg(-1) bw). the fish in the sixth group were coadministe ... | 2002 | 12093041 |
| a common origin of complex life cycles in parasitic flatworms: evidence from the complete mitochondrial genome of microcotyle sebastis (monogenea: platyhelminthes). | the parasitic platyhelminthes (neodermata) contains three parasitic groups of flatworms, each having a unique morphology, and life style: monogenea (primarily ectoparasitic), trematoda (endoparasitic flukes), and cestoda (endoparasitic tapeworms). the evolutionary origin of complex life cyles (multiple obligate hosts, as found in trematoda and cestoda) and of endo-/ecto-parasitism in these groups is still under debate and these questions can be resolved, only if the phylogenetic position of the ... | 2007 | 17270057 |
| molecular cloning, functional characterization and localization of an annexin from a fish gill fluke microcotyle sebastis (platyhelminthes: monogenea). | the full cdna of an annexin gene from microcotyle sebastis (msanx) was cloned for the first time in monogeneans. the cdna of msanx comprises 1199bp with a 29bp 5' untranslated region, an open reading frame of 1062bp, and a 108bp 3' untranslated region. the recombinantly produced msanx bound phosphatidylserine vesicles in the presence of ca2+, whereas no msanx was precipitated in the absence of free ca2+. phylogenetically, msanx formed a cluster with human annexin a13, known as the earliest annex ... | 2009 | 18955089 |
| the mitochondrial genome of polylabris halichoeres (monogenea: microcotylidae). | this study presents the complete mitochondrial (mt) genome of polylabris halichoeres, which is the largest mt genome sequenced of monogeneans so far and the second complete sequence after microcotyle sebastis from the microcotylidae. it is basically similar to that of m. sebastis, with the exception of a high level of gene rearrangement located between trnc and trnl((uur)), a translocation of trnm and trnh, as well as a highly repetitive region (hrr) in the large non-coding region (ncr). we also ... | 2011 | 21707321 |
| Post-larval development of the microcotylid monogenean Sparicotyle chrysophrii (Van Beneden and Hesse, 1863): comparison with species of Microcotylidae and Heteraxinidae. | The chronology of post-larval development in S. chrysophrii, a polyopisthocotylean monogenean parasite of the gilthead seabream (Sparus aurata L.), was experimentally studied. It is compared with other species within the Microcotylidae and the Heteraxinidae, including an analysis of the changes in attachment and the growth rate. Gilthead seabreams infected by larvae of S. chrysophrii were killed periodically in order to collect the different developmental stages. Parasite total body length, hapt ... | 2011 | 22015332 |
