seasonal variation in the population dynamics of caryophyllaeus laticeps.the biological parameters which generate seasonal fluctuations in the size of populations of caryophyllaeus laticeps are examined in detail. a mathematical model is formulated to describe the dynamics of the adult parasite within the fish host abramis brama, and the predictions of the model are compared with observed population data. the seasonality of parasite population size is shown to be caused by the combined effects of a temperature dependent mortality rate and flucate of larval parasites. ...1976967520

[hydrolytic activity of enzymes produced by symbiotic microflora and its role in digestion processes of bream and its intestinal parasite caryophyllaeus laticeps (cestoda, caryopyllidea)].bacteria capable to secrete enzymes hydrolyzing proteins and carbohydrates proved to be associated with the digestive-transport surfaces of the bream intestine and tegument of cestode caryophyllaeus laticeps. apparently, the contribution of symbiotic digestion to the hydrolysis of polymers increases during active feeding of fishes, while at low feeding rate, bacteria can compete with the host and its parasite for the available monomers. secretion of bacterial enzymes hydrolyzing both complex car ...200616771150
[the action of fenasal on the ultrastructure of the tegument in caryophyllaeus laticeps cestodes].the effect of the anthelmintic preparation fenasal on the fine structure of tegument of the cestode caryophyllaeus laticeps, a parasite of cyprinidae, was studied in vitro. 10 mcg/ml concentration of fenasal causes numerous evaginations of the external cytoplasmic layer in the scolex of helminth. inside these formations there are granules of secretion, mitochondria, vacuoles. at the same time microtrichia disappear from the surface, cytoplasmic layer gets thinner and its mitochondria degenerate. ...19883226774

phenotypic plasticity in caryophyllaeus brachycollis janiszewska, 1953 (cestoda: caryophyllidea): does fish host play a role?recent molecular phylogenetic studies on fish tapeworms of the genus caryophyllaeus gmelin, 1790 (cestoda: caryophyllidea), parasites of cyprinid fishes in the palaearctic region, have revealed unexpected phenotypic plasticity that seems to be related to definitive hosts. in the present paper, caryophyllaeus brachycollis janiszewska, 1953 is redescribed and its two morphotypes are circumscribed on the basis of newly-collected specimens. morphotype 1 from barbels [barbus spp. including the type-h ...201424832186
conflict between morphology and molecular data: a case of the genus caryophyllaeus (cestoda: caryophyllidea), monozoic tapeworms of cyprinid fishes.molecular analysis of an extensive specimen collection of morphologically distinct tapeworms of the genus caryophyllaeus gmelin, 1790 (cestoda: caryophyllidea), parasites of cyprinid fishes in the palaearctic region, brought evidence of host-related plasticity in critical morphological characters widely used for species circumscription and classification of these tapeworms. the results obtained here do not support the traditionally used morphological concept of species-defining characters of the ...201425185405
morphological polymorphism in tapeworms: redescription of caryophyllaeus laticeps (pallas, 1781) (cestoda: caryophyllidea) and characterisation of its morphotypes from different fish hosts.recent morphological and molecular data have shown that one of the most common parasites of freshwater fish in the palaearctic region, the cestode caryophyllaeus laticeps (pallas, 1781) (eucestoda: caryophyllidea), is highly polymorphic. five distinct morphotypes of c. laticeps, largely corresponding to different fish hosts and representing separate, yet closely related genetic lineages, have been recognised and they are characterised in the present paper. morphotype 1 from breams, abramis brama ...201525655116
