Parasitological Examination Of Wasting Disease In Black Abalone, Haliotis Cracherodii : Final Report, Jeffrey D. Shields, Frank O. Perkins Jan 1997

Parasitological Examination Of Wasting Disease In Black Abalone, Haliotis Cracherodii : Final Report, Jeffrey D. Shields, Frank O. Perkins

Reports

Black abalone in southern California are afflicted with chronic intestinal infections of a rickettsia-like organism that causes a debilitating and fatal withering syndrome. The hematology of withered animals indicated that cellular degradation and apoptosis occurred in tandem with the · decline and catabolism of abalone tissues. Two types of hemocytes were found in the hemolymph. Type I and Type II Hyalinocytes were distinguished by subtle differences in their cytoplasmic vesicles. Densities of both types of hemocytes declined in abundance, and small, presumptive stem cells increased in abundance with the progression of the disease. No circulating granulocytes were present in hemolymph; …

Environmental Control Of Perkinsus Marinus And Elucidation Of Over Wintering Infections : Final Report, Eugene M. Burreson, Lisa M. Ragone Calvo

Reports

The role of low temperature and low salinity in controlling P. marinus was investigated under laboratory conditions which simulated typical and extreme winter and spring environmental conditions.


Achievements Of Soviet Scientists In Investigations Of The Helminthofauna Of Marine Animals Of The World Ocean, S. L. Delamure, A. S. Skriabin Jan 1985

Achievements Of Soviet Scientists In Investigations Of The Helminthofauna Of Marine Animals Of The World Ocean, S. L. Delamure, A. S. Skriabin

Reports

During the last 40 yr (1940 to 1980), Soviet helminthologists have examined about 9,680 specimens of marine mammals In the Northern and Southern Hemispheres, using uniform or standard methods In most cases. As a result, 20 new species of trematodes [digeneids], 19 cestodes, 9 acanthocephalans, and 23 nematodes have been described. Also several new supraspecific taxa have been established. Systematic revisions of Campuidae, Tetrabothriidae, Pseudallidae, and Anisakidae have been undertaken. The morphology, adaptation of helminths to their environments and to the host's mode of life, Infection rates and characteristics, and the seasonal and age dynamics of the helmlnthofauna have been …


Bibliography Of The Monogenetic Trematode Literature Of The World, 1758 To 1982, William J. Hargis Jr., Dennis A. Thoney May 1983

Bibliography Of The Monogenetic Trematode Literature Of The World, 1758 To 1982, William J. Hargis Jr., Dennis A. Thoney

Reports

Interest in the monogenean parasites has grown markedly in the last twenty years. To enhance and speed world-wide research activity, we prepared the first edition of this bibliography in 1969. This latest effort is intended to do the same.


Morphology Of Udonella Caligorum Johnston, 1835, And The Position Of Udonellidae In The Systematics Of Platyhelminths, A. V. Ivanov Jan 1981

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.


Zoogeography And Host-Specificity Of The Superfamily Capsaloidea Price, 1936 (Monogenea, Monopisthocotylea) : An Evaluation Of The Host-Parasite Locality Records Of The Superfamily Capsaloidea Price, 1936, And Their Utility In Determinations Of Host-Specificity And Zoogeography, Adrian R. Lawler Jan 1981

Zoogeography And Host-Specificity Of The Superfamily Capsaloidea Price, 1936 (Monogenea, Monopisthocotylea) : An Evaluation Of The Host-Parasite Locality Records Of The Superfamily Capsaloidea Price, 1936, And Their Utility In Determinations Of Host-Specificity And Zoogeography, Adrian R. Lawler

Reports

Original literature on the super family Capsaloidea Price, 1936 published prior to May 1968 was examined for parasite-host locality records in order to study the host-specificity and zoo­geography of the super family. Complete locality records, synonyms, and references for 221 species of capsaloids belonging to 70 genera and five families and parasitizing over 260 natural hosts are given. New locality records are given for Dioncus agassizi, D. remora, and Caballerocotyla manteri. Host-specificity tables are given f or all species. The host names have been updated, and the host ranges documented. Comments are made on conf used and elroneous records. The …


Ontogenesis And Phylogenetic Interrelationships Of Parasitic Flatworms, Boris E. Bychowsky Jan 1981

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 …

Bibliography Of The Monogenetic Trematode Literature Of The World, 1758 To 1969, W. J. Hargis Jr., A. R. Lawler, R. Morales-Alamo, D. E. Zwerner Sep 1969

Bibliography Of The Monogenetic Trematode Literature Of The World, 1758 To 1969, W. J. Hargis Jr., A. R. Lawler, R. Morales-Alamo, D. E. Zwerner

Reports

In preparing this bibliography we have attempted to collect all literature references pertaining to the Monogenea. Accordingly it represents an up-to-date (through September 1969) guide to the literature of these parasites, and is of maximum scope, including not only taxonomic literature but also references to ecological and physiological studies on Monogenea as well as reports of preferred methods of treating infestations of these parasites.
