the life cycle of monorchis parvus (digenea: monorchiidae) demonstrated by developmental and molecular data.	cercaria cerastodermae i, a digenean parasite of cerastoderma edule, was recorded for the first time in the atlantic ocean off the iberian peninsula. sporocysts were present in the hemolymph of the digestive gland, gonad, gills, and foot of the mollusc. most of the cercariae present within sporocysts were encysted as metacercariae. the corresponding adult stages were obtained after experimental infection of several diplodus sargus artificially reared in fish farms and that had previously been pr ...	2000	10864243
species diversity among the genus monorchis (digenea: monorchiidae) parasitic in marine teleosts: molecular, morphological and morphometrical studies with a description of monorchis blennii n. sp.	molecular, morphological and morphometrical studies were conducted on two species of the genus monorchis (monorchiidae), monorchis parvus and monorchis monorchis, collected in different fish hosts from the mediterranean sea. the analysis of internal transcribed spacer 1 sequences of ribosomal dna showed that m. monorchis specimens from parablennius gattorugine were strongly divergent (12.9%) from specimens of this species collected in spondyliosoma cantharus and diplodus puntazzo. this high gene ...	2002	11954908
ultrastructure of spermiogenesis and the spermatozoon of monorchis parvus looss, 1902 (digenea, monorchiidae), a parasite of diplodus annularis (pisces, teleostei).	the present paper describes the characteristic ultrastructural features of spermiogenesis and the spermatozoon of monorchis parvus (trematoda, digenea, monorchiidae). this spermiogenesis is characterized by a flagellar rotation of about 120 degrees and the formation of a novel ultrastructural element: a centriolar extension. it nevertheless follows the general pattern of digeneans. it begins with the formation of a differentiation zone, comprising striated rootlets associated with two centrioles ...	2004	15118909
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
ultrastructure of the spermatozoon of helicometroides atlanticus (digenea, monorchiidae), an intestinal parasite of parapristipoma octolineatum (pisces, teleostei) in senegal.	the mature helicometroides atlanticus spermatozoon exhibits an anterior electron-dense material, two axonemes of the 9+"1" pattern, a nucleus, two mitochondria, extramembranous ornamentations located at the level of the first mitochondrion and cortical microtubules arranged into two fields: a ventral field corresponding to the mitochondrial side and a dorsal field corresponding to the nuclear side. it lacks of spine-like body and a cytoplasmic expansion as in monorchis parvus the only species of ...	2015	25660562
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
