| associations between fish reproductive cycle and the dynamics of metazoan parasite infection. | the parasite fauna of the stone loach (barbatula barbatula) was investigated monthly from may to december 2001. four parasite species were recorded: gyrodactylus spp. (monogenea), tylodelphys clavata (digenea), proteocephalus sagittus (cestoda), and raphidascaris acus (nematoda). the changes in the seasonal dynamics of parasite infection were investigated throughout the 8 months. the potential effect of the reproductive investment of the host, measured by gonad mass and gonado-somatic index (gsi ... | 2005 | 15565460 |
| proteocephalid tapeworms (cestoda: onchoproteocephalidea) of loaches (cobitoidea): evidence for monophyly and high endemism of parasites in the far east. | the parasite fauna of loaches (cypriniformes: cobitoidea), a group of small bottom-dwelling freshwater fishes with a mostly eurasian distribution, remains a largely unknown quantity. here we revise the taxonomy of tapeworms of the genus proteocephalus weinland, 1858 (cestoda: proteocephalidae) that had been found in loaches from the palaearctic region (central europe, japan and russia [primorsky region]). molecular phylogenetic analysis based on two nuclear (ssr- and lsrdna) and two mitochondria ... | 2017 | 27702602 |
| seasonal dynamics of proteocephalus sagittus in the stone loach barbatula barbatula from the hana river, czech republic. | the seasonal cycle of the cestode proteocephalus sagittus (cestoda: proteocephalidae) was studied for the first time in the stone loach barbatula barbatula from the hana river, czech republic. a total of 180 loaches were examined monthly from january to december 2001. the parasite occurred in loaches throughout the year but infection parameters differed significantly among seasons, with the highest values of prevalence and abundance from the late winter to the early summer. parasite recruitment ... | 2004 | 15469625 |
| resurrection of proteocephalus sagittus (grimm, 1872) (cestoda: proteocephalidea) based on morphological and molecular data. | this paper presents a redescription of the proteocephalidean cestode proteocephalus sagittus (grimm, 1872) based on freshly collected specimens from the type-host, the stone loach barbatula barbatula (l.) (family balitoridae), from the czech republic. this species has recently been synonymised with p. torulosus (batsch, 1786), a parasite of cyprinid fishes in the holarctic region, but it differs in the following characters: (i) scolex morphology (scolex rounded, with more apically situated sucke ... | 2003 | 14707502 |
