Epizootiology Of Late Summer And Fall Infections Of Oysters By Haplosporidium Nelsoni, And Comparisons To Annual Life Cycle Of Haplosporidium Costalis, A Typical Haplosporidan, J. D. Andrews

VIMS Articles

The two haplosporidan parasites that cause diseases of oysters along the middle North Atlantic coast of North America differ in their habitats, in timing of oyster mortalities, and in their adaptations to the host. Haplosporidium nelsoni (MSX) kills oysters throughout the year over a wide range of salinities (about 15 to 30 ppt). It has a long infective period of nearly 6 months. This pathogen rarely completes sporulation in its life cycle in oysters. It is highly pathogenic and exhibits irregular activity suggesting that it is poorly adapted to the host species. In contrast, Haplosporidium costalis (SSO) has a short, …

Morphology Of Udonella Caligorum Johnston, 1835, And The Position Of Udonellidae In The Systematics Of Platyhelminths, A. V. Ivanov

Reports

The platyhelminth, Udonella, lives on parasitic copepod crustaceans and, according to the present system of classification belongs to monogenetic trematodes (Monogena) among which it is usually placed in the group Monopisthocotylea (Fuhrmann, 1928; Bychowsky, 1937; Dawes, 1946; Sproston, 1946). However, the morphology of Udonella has not yet been studied thoroughly by anyone, and a number of unusual features of the structure, ontogenesis and biology of this form cause doubts with regard to its belonging to the Monogena.

Ontogenesis And Phylogenetic Interrelationships Of Parasitic Flatworms, Boris E. Bychowsky

Reports

The purpose of this report is to establish relationship among individual groups of parasitic flatworms, namely, among monogenetic trematodes (Monogenea), digenetic trematodes (Digenea), tapeworms proper (Cestoda), and the so-called Cestodaria group (AMPHILINIDAE and GYROCGTYLIDAE). The attempt to establish the above-mentioned relationships is made to a variable degree for different groups. The main point of this report is the establishment of phylogenetic relationship in the Monogenea, not only for the entire group as a whole, but also for the individual families which are members of this group. We feel that another important point is our attempt at clarifying the phylogenetic position …

Parasites Of California Marine And Estuarine Fish, Milton S. Love, Mike Moser

Harold W. Manter Laboratory of Parasitology: Faculty and Staff Publications

While working on the parasites of several California marine fish, it was difficult to find out which parasites had been reported from our fish. Pertinent sources were scattered over a number of journals, covering many years. We compiled this list because we felt there was a need for a single source which would give all the parasites infecting California marine fish. As "marine fish" was a somewhat vague term, we decided to use it in a broad sense and included estuarine and anadromous fish in the survey. In addition, we have included records from landlocked populations of anadromous fish, such …

Parasites Of Channel Catfish In Illinois Hatcheries, Charles Dale Meryman

Masters Theses

Ninety channel catfish (Ictalurus punctatus) were trapped during September 1973 through April 1974 at three hatcheries located at Worden, Centralia, and Kinmundy, Illinois. All were examined for parasites and 87 were parasitized. The trematodes Azygia angusticauda and Neascus sp. were found in the gastrointestinal system and Cleidodiscus floridanus and Dactylogyrus sp. were attached to the gills. Five cestode genera, including Bothriocephalus sp., Corallobothrium giganteum, Eubothrium sp., Haplobothrium sp., and Proteocephalus ambloplitis were present. Rhabdochona sp. was the only nematode found. Protozoans; Costia sp., Myxobolus sp., Scyphidia macropodia and Trichodina discoidea and one kind of glochidium were observed. …

Parasites From Gizzard Shad, Dorosoma Cepedianum, In Lake Charleston, Illinois, Francis M. Yabai Kaikumba

Masters Theses

Eighty gizzard shad (Dorosoma cepedianum) from Lake Charleston, Charleston, Illinois were examined for parasites. Eight fish were parasitized. Three fish contained the acanthocephalan Tanaorhamphus longirostris, three fish harbored cestodes of the genus Glaridacris and two fish had the nematode Camallanus oxycephalus. The latter is here reported for the first time from gizzard shad. Twenty fish were infected with the fungus Saprolegnia sp. The numbers of helminth parasites harbored by shad are less than reported for other forage fish. However, the incident of parasitism reported in this study is greater than that reported by previous workers.

Parasites Of Some Penaeid Shrimps With Emphasis On Reared Hosts, Robin M. Overstreet

Harold W. Manter Laboratory of Parasitology: Faculty and Staff Publications

Information is presented about parasites and commensals of penaeid shrimps, allowing those who rear shrimps and those who are interested in associated organisms of shrimp to have a better knowledge of the organisms that are or may be associated with brown, white, and pink shrimps. It covers common and rare organisms and diseases, primarily in the northern Gulf of Mexico, listing several previously unreported species including an undescribed gregarine, a larval nematode (Spirocarnallanus pereirai), a commensal nematode (Leptolaimus sp.), a leech (Myzobdella lugubris), a blue-green alga (Schizothrix calcicola), a hydroid (Obelia bicuspidata …

Bibliography Of Diseases And Parasites Of Marine Fish And Shellfish (With Emphasis On Commercially Important Species), Carl J. Sindermann

Harold W. Manter Laboratory of Parasitology: Faculty and Staff Publications

The literature on diseases and parasites of marine animals has been accumulating at an accelerating rate in recent decades, and at a seemingly geometrical rate in the past few years. Reviews of selected aspects of the subject have appeared (Cheng, 1967; Sindermann, 1966; Sindermann and Rosenfield, 1967). References listed in these papers include a significant, but still a small part, of the available literature. With the proliferation of journals in many languages throughout the world, a complete bibliography, even in a narrow area of research, is almost an impossibility. Then too, the daily appearance of new published information represents an …

A New Genus Of Trematode (Digenea: Gorgoderidae) From The Ureter Of Tuna Fish (Thunnus Thynnus Maccoyii) In Australia, Harold W. Manter

Harold W. Manter Laboratory: Library Materials

A large, digenetic trematode is described from the ureter of the tuna Thunnus thynnus moccoyii from southern Australian waters. It represents a new genus and species, Cetiotrema crassum (subfamily Gorgoderinae) distinguished by the size and shape of the body, the caeca being distant from the sides of the body, the uterus being intercaecal, the vitellaria arising as three claviform lobes on each side and the seminal vesicle at least partly anterior to the genital pore.

The genus is close to Phyllodistomum Braun; P. carangi Manter, 1947, is considered to belong to Cetiotrema; P. lancea Mamaev, 1968 is very similar …

Phlyctainophora Squali Sp. Nov. (Nematoda, Philometridae) From The Spiny Dogfish, Squalis Acanthias, Dwight R. Mudry, Murray D. Dailey

Harold W. Manter Laboratory: Library Materials

Summary

Phlyctainophora squali sp. nov. is described from 23 female specimens recovered from the subcutaneous tissue of one of 440 Squalis acanthias caught off Los Angeles, California. This finding represents a new host and distribution for this genus. Phlyctainophora is placed in the family Philometridae on the basis of atrophication of vulva and anus, simple mouth, viviparity and location in tissue of fishes. The family diagnosis for Philometridae is amended to include Phlyctainophora which lacks an anterior ovary.

Digenetic Trematodes Of Marine Fishes Of Puerto Rico, Ather H. Siddiqi, Raymond M. Cable

Harold W. Manter Laboratory: Library Materials

Preface

This monograph reports the major part of an investigation begun by Raymond M. Cable in 1951, when he spent one year at the College of Agriculture and Mechanic Arts, University of Puerto Rico, Mayagiiez, Puerto Rico, collecting and studying larval trematodes and the helminth parasites of shore birds and marine fishes. The work there was done under the auspices set forth in the Preface to Part 4, Volume 16, of this series; this part was facilitated especially by Virgilio Biaggi, N. T. Mattox, and Donald Erdman, who rendered invaluable assistance in the collection and identification of fishes. One trip …

An Additional Trematode From Tortugas, Florida, And A New Name For Opisthoporus Manter, 1947, Preoccupied, Harold W. Manter

Harold W. Manter Laboratory: Library Materials

Professor José M. Ruiz of Sao Paulo, Brazil, has kindly called my attention to the fact that the generic name Opisthoporus Manter, 1947 had been used several times previously, a condition which I had indeed checked but thoughtlessly forgot. For Opisthoporus Manter, 1947 (nec Opisthoporus Benson, 1851; Opisthoporus Minot, 1877; Opisthoporus Fukui, 1929), the name Postporus is proposed. The two species become Postporus epinepheli (Manter, 1947) and Postporus mycteropercae (Manter, 1947).

The combination Pleurogonus candidulus (Linton, 1910) (misspelled "candibulus" in my paper) had been made in 1946 by Ruiz (1946: 295) where, however, it was first printed " …

Notes On The Trematode Subfamily Loimoinae (Monogenea), With A Description Of A New Genus, Harold W. Manter, Waldo L. Schmitt

Harold W. Manter Laboratory: Library Materials

The subfamily Loimoinae was named by Price (1936) for a peculiar monogenetic trematode, Loimos salpinggoides MacCal lum, 1917, from the gills of a dusky shark, Carcharias obscurus (Lesueur), at Woods Hole, Massachusetts, USA. Price (1938) redescribed this trematode, correcting several errors made by MacCallum. Manter (1938) described Tricotyle scoliodoni from a shark, Scoliodon terrae-novae (Richardson), from Beaufort, North Carolina, USA. He noted some similarities between Tricotyle and Loimos. The redescription of Loimos by Price increased these similarities.

Some Digenetic Trematodes From Deep-Water Fish Of Tortugas, Florida, Harold W. Manter

Harold W. Manter Laboratory: Library Materials

Introduction (first two paragraphs)

The parasitic fauna of ocean depths is practically unknown. Although an extensive fish population occurs at all depths, very little study has yet been made on the helminths of these fish. During the summers of 1930, 1931, and 1932 excellent opportunity was offered for the collection of parasites from fish trawled from depths varying from 40 to 582 fathoms at Tortugas, Florida. A considerable number of systematic hauls by the staff and crew of the Tortugas Biological Laboratory of the Carnegie Institution of Washington yielded an abundance and considerable variety of fish, some of rare forms, …
