molecular cytogenetics in digenean parasites: linked and unlinked major and 5s rdnas, b chromosomes and karyotype diversification.	digenetic trematodes are the largest group of internal metazoan parasites, but their chromosomes are poorly studied. although chromosome numbers and/or karyotypes are known for about 300 of the 18,000 described species, molecular cytogenetic knowledge is mostly limited to the mapping of telomeric sequences and/or of major rdna clusters in 9 species. in this work we mapped major and 5s rdna clusters and telomeric sequences in chromosomes of bucephalus minimus, b. australis, prosorhynchoides carva ...	2015	26680763
review: bucephalus minimus, a deleterious trematode parasite of cockles cerastoderma spp.	trematodes are the most prevalent and abundant macroparasites in coastal waters. they display a complex life cycle with alternation of free-living and parasitic stages generally involving three host species. the most deleterious stage is in the first intermediate host (a mollusc) where the parasite penetrates as miracidium larvae and asexually multiplicates in sporocysts/rediae to provide cercariae larvae. however, due to basic low prevalence in ecosystems, this system remains difficult to study ...	2015	25681142
dynamics of bacterial communities in cockles (cerastoderma edule) with respect to trematode parasite (bucephalus minimus) infestation.	the bacterial communities associated with the cockle (cerastoderma edule) were investigated at the individual level through a 10-month monitoring programme. temporal changes and those changes associated with a common parasite of the cockle, bucephalus minimus, were investigated by monthly sampling of individuals, selected based on their shell length (cohort monitoring). cockle bacterial community abundance (cbca) and diversity (cbcd) were estimated by epifluorescence microscopy counts and automa ...	2011	21584755
digenean trematodes-marine mollusc relationships: a stable isotope study.	the stable carbon and nitrogen isotopic composition of digenean trematode parasites and their marine mollusc hosts was investigated to describe the potential influence of parasites on their host and its different tissues, and to obtain further insight into their trophic relationships. four parasite-host systems were studied: labratrema minimus-cerastoderma edule, monorchis parvus-c. edule, lepocreadiidae parasites-nassarius reticulatus and zoogonidae parasites-n. reticulatus. among the 4 samplin ...	2009	19419008
identification and description of bucephalus minimus (digenea: bucephalidae) life cycle in portugal: morphological, histopathological, and molecular data.	the cercaria of bucephalus minimus infects the digestive gland and gonads of its first intermediate host, the edible cockle, cerastoderma edule. light microscopy (lm) and scanning electron microscopy (sem) of the cercaria showed a tail formed by a central stem, with 2 long contractile arms presenting distinct morphological surfaces. the encysted metacercaria naturally infected the flathead grey mullet, mugil cephalus. the cysts found in the heart, liver, and spleen were shown to be identical by ...	2009	18710298
evidence of an altered protective effect of metallothioneins after cadmium exposure in the digenean parasite-infected cockle (cerastoderma edule).	the aim of the present study was to analyse the relation between parasitism and subsequent metallothioneins (mt) in the case of metal contamination. experimental exposure of parasitized and unparasitized cockles (cerastoderma edule) to cadmium (cd) was performed, with the cockle as first or second intermediate host of 2 digenean species. after 7 days of cd exposure in microcosms, cockles infected as first intermediate host by labratrema minimus exhibited metal concentrations in tissues double th ...	2007	17032474
impact of digenean parasite infection on metallothionein synthesis by the cockle (cerastoderma edule): a multivariate field monitoring.	metallothioneins (mt) are proteins that play an important role in metabolism of essential metals and detoxification of trace metals from living organisms. their synthesis is induced by metal pollution but can also be exacerbated by other factors such as reproduction processes. in this context, we monitored mt concentrations in a cockle cerastoderma edule (marine bivalve) population and highlighted the effect of a castrating digenean parasite, labratrema minimus. in spent cockles, mt levels were ...	2006	16257015
cockle emergence at the sediment surface: 'favourization' mechanism by digenean parasites?	the aim of the present work was to assess the effect of digenean trematodes on indirect mortality of the cockle cerastoderma edule, an infaunal bivalve. the tested hypothesis was that parasites altered the burrowing capacity of cockles and thus exposed them at the sediment surface, where they are more vulnerable to predators. if the predator is the final host, this mechanism, which drives the cockle out of the sediment, is considered as a 'favourization'. cockle populations from 2 stations in ar ...	2002	12542091
effects of the digenean parasites labratrema minimus and cryptocotyle concavum on the growth parameters of pomatoschistus microps and p. minutus from southwest wales.	during the present study, about 800 specimens of gobies (pomatoschistus microps and p. minutus) from two sites at gower peninsula, southwest wales, were studied. both species were infected with the digenean parasites labratrema minimus and cryptocotyle concavum. the effects of these parasites on host-growth parameters such as the condition factor, the gutted condition factor, the hepatosomatic index, and the gonadosomatic index were considered. the results of multiple regression and hierarchical ...	2001	11355688
the parasite community infecting flounders, platichthys flesus, in the tidal thames.	the composition of the parasite fauna of the flounder, platichthys flesus, retrieved from two locations in the tidal thames is described in detail for the first time. the combined parasite species list of the flounders from lots road in the upper tideway and west thurrock in the middle tideway consisted of one protozoan (glugea stephani), one monogenean (gyrodactylus sp.), four larval digeneans (cryptocotyle concava, timoniella imbutiforme, t. praeterita, and labratrema minimus), five adult dige ...	1999	10526412
population dynamics of the metacercarial stage of the bucephalid trematode, labratrema minimus (stossich, 1887) from salses-leucate lagoon (france) during the cercarial shedding period.	the population dynamics of labratrema minimus (stossich, 1887) metacercariae (trematoda, bucephalidae) were studied in its second intermediate fish host atherina boyeri from salses-leucate lagoon (northwest mediterranean sea, south of france), during the cercarial shedding period. the infection parameters (prevalence and mean abundance of infection) showed the high susceptibility of silversides (juveniles and adults) to infection. the observed variation in the mean abundance of infection with re ...	1994	8006382
