ultrastructure of spermiogenesis and the spermatozoon of opecoeloides furcatus (trematoda, digenea, opecoelidae), a parasite of mullus barbatus (pisces, teleostei).	spermiogenesis and mature spermatozoa of opecoeloides furcatus (digenea, opecoelidae) are described by means of transmission electron microscopy. spermiogenesis in this fluke matches the general pattern of digenetic trematodes. striated rootlets associated with the two centrioles and an intercentriolar body are present in the differentiation zone. flagellar rotation of two flagella and their proximodistal fusion with a median cytoplasmic process also characterize the spermiogenesis of o. furcatu ...	2000	10780739
the life cycle of opecoeloides columbellae (pagenstecher, 1863) n. comb. (digenea, opecoelidae): evidence from molecules and morphology.	the cosmopolitan digenean family opecoelidae comprises several hundred species, whose adults live in the digestive tract of marine and freshwater fishes. the genus opecoeloides odhner, 1928 is represented in the mediterranean by a single species, opecoeloides furcatus (bremser in rudolphi, 1819), that has been recorded from six definitive hosts species. to see if this broad host range could be the result of an underestimation of species diversity, we obtained its1 ribosomal dna sequences as well ...	2000	10856510
the occurrence of two opecoeliid digeneans in mullus barbatus and m. surmuletus from the spanish south-eastern mediterranean.	the infection by opecoeloides furcatus and poracanthium furcatum (opecoeliidae) was studied in 121 mullus barbatus and 113 m. surmuletus collected from the spanish south-eastern mediterranean. the prevalence of infection was most frequent in m. surmuletus with values of 81.42% for o. furcatus and 38.05% for p. furcatum. in m. barbatus the prevalences of o. furcatus and p. furcatum were 54.54% and 14.88% respectively. statistically significant differences were found between the infection of the t ...	2000	10881288
parasite communities in the red mullet, mullus barbatus l., respond to small-scale variation in the levels of polychlorinated biphenyls in the western mediterranean.	we examined parasite populations and communities in the mediterranean sentinel fish species, mullus barbatus, sampled at a small-scale pcb gradient at the shelf sediments off catalonian coasts of the western mediterranean. a recurrent feature at both the population and community level was the differentiation of the samples along the increasing pcb levels simultaneously registered in the sediments. both directly transmitted ectoparasites and endoparasites with complex life-cycles transmitted via ...	2012	22748503
