Platyhelminthes: Amphilinidea)

Poddubnaya2 and Willi E. R. Xylander3 1 Institute of Parasitology, Slovak Academy of Sciences, Hlinkova 3, 040 01 Košice, Slovak Republic; 2 I.D. Papanin Institute for Biology of Inland Waters, Russian Academy of Sciences, 152742 Borok, Yaroslavl Province, Russia; 3 Senckenberg Museum für Naturkunde Görlitz, Postfach 300 154, 02806 Görlitz, Germany Abstract: Spermiogenesis in the amphilinidean cestode Amphilina foliacea (Rudolphi, 1819) was examined using transmission electron microscopy. The orthogonal development of the two flagella is followed by a flagellar rotation and their proximodistal fu- sion with the median cytoplasmic process. This process is accompanied by extension of both the mitochondrion and nucleus into the median cytoplasmic process. The two pairs of electron-dense attachment zones mark the lines where the proximodistal fusion of the median cytoplasmic process with the two flagella takes place. The intercentriolar body, previously undetermined inA. foliacea, is composed of three electron-dense and two electron-lucent plates. Also new for this species is the finding of electron-dense material in the apical region of the differentiation zone at the early stage of spermiogenesis, and the fact that two arching membranes appear at the base of the differentiation zone only when the two flagella rotate towards the median cytoplasmic process. The present data add more evidence for a close relationship between the Amphilinidea and the Eucestoda. -

W. Bruno1,*, B. Nowak2, D. G. Elliott3 1FRS Marine Laboratory, PO Box 101, 375 Victoria Road, Aberdeen AB11 9DB, UK 2School of Aquaculture, Tasmanian Aquaculture and Fisheries Institute, CRC Aquafin, University of Tasmania, Locked Bag 1370, Launceston, Tasmania 7250, Australia 3Western Fisheries Research Center, US Geological Survey/Biological Resources Discipline, 6505 N.E. 65th Street, Seattle, Washington 98115, USA ABSTRACT: The identification of protozoan and metazoan parasites is traditionally carried out using a series of classical keys based upon the morphology of the whole organism. However, in stained tis- sue sections prepared for light microscopy, taxonomic features will be missing, thus making parasite identification difficult. This work highlights the characteristic features of representative parasites in tissue sections to aid identification. The parasite examples discussed are derived from species af- fecting finfish, and predominantly include parasites associated with disease or those commonly observed as incidental findings in disease diagnostic cases. Emphasis is on protozoan and small metazoan parasites (such as Myxosporidia) because these are the organisms most likely to be missed or mis-diagnosed during gross examination. Figures are presented in colour to assist biologists and veterinarians who are required to assess host/parasite interactions by light microscopy.

Cestodes in South American Freshwater Teleost Fishes: Keys to Genera and Brief Description of Species
Cestodes in South American freshwater teleost fishes: keys to genera and brief description of species Amilcar Arandas Rego 1 James C. Chubb 2 Gilberto C. Pavanelli 3 ABSTRACT. Keys to genera of cestodes in South American freshwater teleost fi shes are provided, with diagnoses of genera and short descriptions of species. Two new genera are proposed, Chambrie/la gen. n. for Goezee/la agoslinhoi Pavanelli & Santos, 1992 and G. paranaensis Pavanelli & Rego, 1989, and Brooksie/la gcn.n. tor A/JIpho lero/JIO/phus praepulialis Rego, Santos & Silva, 1974. Nomimoscolex /JIagna Rego, Santos & Silva, 1974, previously species inquirenda, is transferred to the genus Proleocephalus Weinland, 1858. Goezee/la nupeliensis Pavanelli & Rego, 1989 is considered a species inquirenda. Species and host lists are included. KEY WORDS . Cestoda, Proteocephalidea, freshwater fi shes, parasitology Eighty nine taxa of cestodes from six orders are known in South American freshwater teleost fishes . Most belong to the Order Proteocephalidea, found parti cularly in siluriform fishes . Classi fication of Proteocephalidea is based on the studies of LA RUE (19 I I, 1914), WOODLAND (I933a,b,c, 1934a,b,c, 1935a,b,c), FREZE (1965), WARDL E & McLEOD (1952), SCHMlDT (1986) and REGO (1994). BROOKS (1978) and BROOKS & RASMUSSEN (1984) acknowledged two major taxa of Proteocephalidea, Proteo cephalidae and Monticelliidae, established by LA RUE (191 I). Separation at fami1y levei was based on arrangement of the reproductive organs in re lation to the longitudinal muscle bund1es. REGO (1995) recommended modification to the taxo nomy, suggesting that South American proteocephalids should be reduced to one family Proteocephalidae, with two subfamilies, Corallobothriinae and Proteocepha linae, distinguished by the presence or absence ofa metascolex. -
Parasites of Cartilaginous Fishes (Chondrichthyes) in South Africa – a Neglected Field of Marine Science
Institute of Parasitology, Biology Centre CAS Folia Parasitologica 2019, 66: 002 doi: 10.14411/fp.2019.002 http://folia.paru.cas.cz Research article Parasites of cartilaginous fishes (Chondrichthyes) in South Africa – a neglected field of marine science Bjoern C. Schaeffner and Nico J. Smit Water Research Group, Unit for Environmental Sciences and Management, Potchefstroom Campus, North-West University, Potchefstroom, South Africa Abstract: Southern Africa is considered one of the world’s ‘hotspots’ for the diversity of cartilaginous fishes (Chondrichthyes), with currently 204 reported species. Although numerous literature records and treatises on chondrichthyan fishes are available, a paucity of information exists on the biodiversity of their parasites. Chondrichthyan fishes are parasitised by several groups of protozoan and metazoan organisms that live either permanently or temporarily on and within their hosts. Reports of parasites infecting elasmobranchs and holocephalans in South Africa are sparse and information on most parasitic groups is fragmentary or entirely lacking. Parasitic copepods constitute the best-studied group with currently 70 described species (excluding undescribed species or nomina nuda) from chondrichthyans. Given the large number of chondrichthyan species present in southern Africa, it is expected that only a mere fraction of the parasite diversity has been discovered to date and numerous species await discovery and description. This review summarises information on all groups of parasites of chondrichthyan hosts and demonstrates the current knowledge of chondrichthyan parasites in South Africa. Checklists are provided displaying the host-parasite and parasite-host data known to date. Keywords: Elasmobranchii, Holocephali, diversity, host-parasite list, parasite-host list The biogeographical realm of Temperate Southern Af- pagno et al. -

Neuropeptide signalling systems in flatworms Abstract Two distinct families of neuropeptides are known to endow platyhelminth nervous systems – the FMRFamide-like peptides (FLPs) and the neuropeptide Fs (NPFs). Flatworm FLPs are structurally simple, each 4–6 amino acids in length with a carboxy terminal aromatic-hydrophobic-Arg-Phe-amide motif. Thus far, four distinct flatworm FLPs have been characterized, with only one of these from a parasite. They ah ve a widespread distribution within the central and peripheral nervous system of every flatworm examined, including neurones serving the attachment organs, the somatic musculature and the reproductive system. The only physiological role that has been identified for flatworm FLPs is myoexcitation. Flatworm NPFs are believed to be invertebrate homologues of the vertebrate neuropeptide Y (NPY) family of peptides. -
