| [on 2 larval trematodes of antedon mediterranea lmk. (echinoderma): metacercaria sp. (monorchiidae odhner, 1911), and metacercaria of diphterostomum brusinae stoss., 1904 (zoogonidae odhner, 1911)]. | | 1966 | 5953772 |
| [new findings of trematodes in commercial fishes of the eastern atlantic]. | three fish trematode species are found from the new hosts: pseudobacciger harengulae in sardina pilchardus and sardinella aurita; diphterostomum brusinae in parapristipoma octolineata, pagellus acarne and umbrina canariensis; lecithocladium angustiovum in pomadasys incisus caught in the east atlantic. all species were found in the new localities. some characters of d. brusinae morphology are detailed. measurements of trematode species from different hosts are given. key to species of genus pseud ... | 1996 | 9480452 |
| 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 |
| morphological and molecular analysis of metacercariae of diphtherostomum brusinae (stossich, 1888) stossich, 1903 from a new bivalve host mytilus galloprovincialis. | the digenean trematode diphtherostomum brusinae (stossich, 1888) stossich, 1903 presents a complex life cycle that may involve more than one intermediate host. the present study represents the first description of the metacercariae from d. brusinae infecting the labial palps of a new intermediate host, mytilus galloprovincialis, in the aveiro estuary, portugal. the morphology of this parasitic stage was studied by light (lm) and scanning electron microscopy (sem) and some differences were report ... | 2010 | 20701832 |
| morphological and molecular studies on life cycle stages of diphtherostomum brusinae (digenea: zoogonidae) from northern portugal. | diphtherostomum brusinae was first recorded by the present study in the north of portugal. sporocysts, containing cercariae and encysted metacercariae, were observed in the gonads and digestive gland of the gastropod nassarius reticulatus. metacercariae were also found infecting the foot, mantle border and gills of the cockle cerastoderma edule. the adult form was lodged in the rectum of the definitive host diplodus sargus. the morphology of the three parasitic stages was studied by light (lm) a ... | 2009 | 19265558 |
| assessment of digenean parasitism in nassarius reticulatus (l.) along the portuguese coast: evaluation of possible impacts on reproduction and imposex expression. | a survey was performed between june and september 2006 along the portuguese coast to assess the prevalence of digenean parasitism in the netted whelk nassarius reticulatus, a bioindicator of tributyltin (tbt) pollution. it was also intended to evaluate the effect of parasites on the reproduction of this gastropod species and their interference on the development of imposex (the superimposition of male characters onto prosobranch females) and male penis, based on field data. five digenean species ... | 2009 | 18712950 |
| spermiogenesis and sperm ultrastructure of diphterostomum brusinae (digenea, zoogonidae), a parasite of diplodus annularis (pisces, teleostei). | this paper constitutes the first ultrastructural study of spermiogenesis and the spermatozoon of a digenea belonging to the family zoogonidae, diphterostomum brusinae. spermiogenesis follows the general pattern found in the digeneans. it begins with the formation of a differentiation zone in the spermatid. the two centrioles give rise to flagella. these two flagella undergo a rotation of 90 degrees and fuse with the median cytoplasmic process. the proximo-distal fusion occurs at the level of att ... | 2004 | 15322926 |
