Miller, and T. T. Dunagan Department of Physiology, Southern Illinois University, Carbondale, Illinois 62901 ABSTRACT: The circular and longitudinal muscles of the body wall of the acanthocephalan, Macra- canthorhynchus hirudinaceus, were studied. Both circular and longitudinal muscles were found to be electrically inexcitable. Evidence was also obtained for a through conduction system located near the median-longitudinal lacunar canal. Isolated muscles could not be stimulated to contract, cut body wall fragments could be stimulated. Strength-duration, tension-time, and relaxation-time curves were obtained. On the basis of the difference in response to stimuli a separate activation system for each set of muscles is postulated. The cuticular layer of the body wall was not necessary for contrac- tion; however, its presence did alter the tension-time and relaxation-time parameters. Considerable variation occurs in the physi- inaceus are considerably different from those ology of invertebrate muscles.

True flies associated with decaying wood add further significant species to the site’s saproxylic fauna. There is also a strong

  • Ultrastructural Observations on the Oncomiracidium Epidermis and Adult Tegument of Discocotyle Sagittata, a Monogenean Gill Parasite of Salmonids
    Parasitology Research https://doi.org/10.1007/s00436-020-07045-z FISH PARASITOLOGY - ORIGINAL PAPER Ultrastructural observations on the oncomiracidium epidermis and adult tegument of Discocotyle sagittata, a monogenean gill parasite of salmonids Mohamed Mohamed El-Naggar1,2 & Richard C Tinsley3 & Jo Cable2 Received: 14 September 2020 /Accepted: 28 December 2020 # The Author(s) 2021 Abstract During their different life stages, parasites undergo remarkable morphological, physiological, and behavioral “metamorphoses” to meet the needs of their changing habitats. This is even true for ectoparasites, such as the monogeneans, which typically have a free-swimming larval stage (oncomiracidium) that seeks out and attaches to the external surfaces of fish where they mature. Before any obvious changes occur, there are ultrastructural differences in the oncomiracidium’s outer surface that prepare it for a parasitic existence. The present findings suggest a distinct variation in timing of the switch from oncomiracidia epidermis to the syncytial structure of the adult tegument and so, to date, there are three such categories within the Monogenea: (1) Nuclei of both ciliated cells and interciliary cytoplasm are shed from the surface layer and the epidermis becomes a syncytial layer during the later stages of embryogenesis; (2) nuclei of both ciliated cells and interciliary syncytium remain distinct and the switch occurs later after the oncomiracidia hatch (as in the present study); and (3) the nuclei remain distinct in the ciliated epidermis but those of the interciliary epidermis are lost during embryonic development. Here we describe how the epidermis of the oncomiracidium of Discocotyle sagittata is differentiated into two regions, a ciliated cell layer and an interciliary, syncytial cytoplasm, both of which are nucleated.

    APPENDIX 1 Classified list of fishes mentioned in the text, with scientific and common names. ___________________________________________________________ Scientific names and classification are from Nelson (1994). Families are listed in the same order as in Nelson (1994), with species names following in alphabetical order. The common names of British fishes mostly follow Wheeler (1978). Common names of foreign fishes are taken from Froese & Pauly (2002). Species in square brackets are referred to in the text but are not found in British waters. Fishes restricted to fresh water are shown in bold type. Fishes ranging from fresh water through brackish water to the sea are underlined; this category includes diadromous fishes that regularly migrate between marine and freshwater environments, spawning either in the sea (catadromous fishes) or in fresh water (anadromous fishes). Not indicated are marine or freshwater fishes that occasionally venture into brackish water.

For the direct life cycle monogenean Discocotyle sagittata infecting rainbow trout, Oncorhynchus mykiss, variables potentially influencing aggregation can be analysed individually. This study was based at a fish farm where every host individual becomes infected by D. sagittata during each annual transmission period. Worm burdens were examined in one trout population maintained in isolation for 9 years, exposed to self-contained transmission.

Acta vet. scand. 1995, 36, 299-318. - An extensive litera­ ture survey on metazoan parasites from rainbow trout Oncorhynchus mykiss has been conducted. The taxa Monogenea, Cestoda, Digenea, Nematoda, Acanthocephala, Crustacea and Hirudinea are covered. A total of 169 taxonomic entities are recorded in rainbow trout worldwide although few of these may prove synonyms in future anal­ yses of the parasite specimens. These records include Monogenea (15), Cestoda (27), Digenea (37), Nematoda (39), Acanthocephala (23), Crustacea (17), Mollusca (6) and Hirudinea ( 5).

A THESI S SUBMITTED FOR THE DEGREE OF DOCTOR OF PHILOSOPHY WITHIN THE UNIVERSITY OF QUEENSLAND JULY, 1982 DECLARATION This thesis has been prepared in accordance with the rules set out in the Combined Higher Degree Handbook 1982, for the degree of Doctor of Philosophy at the University of Queensland. The work presented is this thesis is entirely my own except where otherwise acknowledged and no part of it has been submitted for any other degree at this or any other university R. A. Watson July 1982 ABSTRACT Two new lepocreadiid digeneans, Tetracerasta blepta, gen. nov., sp. nov. and Stegodexamene callista, sp. nov. are described from the intestines of the long-finned freshwater eel, Anguilla reinhardtii, from the Brisbane River, Queensland, and the Australian bass, Macquaria novemaculeata, from the Richmond River, New South Wales, Australia. Their life-cycles have been elucidated and completed in the laboratory. All developmental stages are described and illustrated. Eggs from adults of these lepocreadiid species were obtained from eels. These hatched and miracidia from them injected a precocious sporocyst into uninfected laboratory-reared prosobranch gastropods, Posticobia brazieri. Following two generations of rediae in the digestive gland of the snail, large ophthalmotrichocercous cercariae were produced. The cercariae of..!.:._ blepta penetrated uninfected tadpoles of Litoria lesueuri and the gudgeons, Hypseleotris compressus and ~ galii.
