Cysts Resembling Hydatids In A Chicken, Gerald D. Schmidt, Robert L. Rausch Jan 1986

Cysts Resembling Hydatids In A Chicken, Gerald D. Schmidt, Robert L. Rausch

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Two large cysts recovered from the abdominal cavity of a domestic chicken superficially resembled hydatid cysts of Echinococcus spp. No protoscolices were present. Microscopic examination of the internal lining of one of the cysts revealed a single cuboidal to columnar, ciliated epithelium, leading to a diagnosis of oviduct cysts. Earlier records of hydatids of fowl are reviewed.

Spanish abstract: Reporte de Caso--Quistes en un pollo semejantes a la hidatidosis. Se encontraron dos quistes grandes en la cavidad abdominal de un pollo doméstico. Superficialmente los quistes parecían quistes hidatidícos de Echinococcus spp. No se encontraron escólecis o cabezas de la tenia. …

Helminth Parasites Of Thomomys Bulbivorus (Richardson) (Rodentia: Geomyidae), With The Description Of A New Species Of Hymenolepis (Cestoda), Scott Lyell Gardner Jun 1985

Helminth Parasites Of Thomomys Bulbivorus (Richardson) (Rodentia: Geomyidae), With The Description Of A New Species Of Hymenolepis (Cestoda), Scott Lyell Gardner

Harold W. Manter Laboratory of Parasitology: Faculty Publications

A cestode, Hymenolepis tualatinensis n. sp., is described from the pocket gopher, Thomomys bulbivorus (Richardson) (Rodentia: Geomyidae), from the Willamette Valley in Oregon. Helminths of four additional species were found. Trichuris fossor Hall, 1916, Ransomus rodentorum Hall, 1916, Heligmosomoides thomomyos Gardner and Jasmer, 1983, and Hymenolepis horrida (von Linstow, 1901), of which all but H. thomomyos represent new host records. A significant change in prevalence of the whipworm T. fossor in the population of T. bulbivorus from spring through summer was noted. Significant differences in prevalence of infection of helminths in pocket gophers collected from two different …


Nearshore Foodwebs And The Distribution Of Acanthocephalan Parasites In Antarctic Seabirds, Eric P. Hoberg Jan 1985

Nearshore Foodwebs And The Distribution Of Acanthocephalan Parasites In Antarctic Seabirds, Eric P. Hoberg

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Field studies, in the vicinity of Palmer Station during the austral summer of 1982— 1983, yielded an extensive collection of acanthocephalans and other parasites from seabirds, fish and invertebrates. The continuing analysis of this material has resulted in the elucidation of factors that control the occurrence of Corynosoma spp. in Antarctic seabirds. Notably, the host-distribution of Corynosoma spp. suggested that these parasites were being acquired from piscine or possibly amphipod prey, generally in nearshore habitats.


Alcataenia Pygmaeus Sp. N. (Cestoda: Dilepididae) From The Whiskered Auklet, Aethia Pygmaea, In The Western Aleutian Islands, Alaska, With A Comment On The Genera Alcataenia And Rissotaenia, Eric P. Hoberg Jul 1984

Alcataenia Pygmaeus Sp. N. (Cestoda: Dilepididae) From The Whiskered Auklet, Aethia Pygmaea, In The Western Aleutian Islands, Alaska, With A Comment On The Genera Alcataenia And Rissotaenia, Eric P. Hoberg

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Alcataenia pygmaeus sp. n. is described from whiskered auklets, Aethia pygmaea (Gmelin), from the western Aleutian Islands, Alaska. It is distinguished from its congeners by the overall small size of the strobila and a combination of other characters. The rostellum is armed with 34-38 hooks that measure 41-49 µm in length. The cirrus sac is relatively short, 101-174 µm in length, and reaches or just crosses the poral osmoregulatory canals. There are 36-50 testes located entirely posterior to the female organs. The scolex is deeply embedded in the mucosal tissue of the duodenum of the host. This is the first …


Myxomatosis In Western Australia, D R. King, S. H. Wheeler Jan 1984

Myxomatosis In Western Australia, D R. King, S. H. Wheeler

Journal of the Department of Agriculture, Western Australia, Series 4

Since myxomatosis was introduced to Western Australia in the early 1950s rabbit plagues have ceased. However, myxomatosis has not proven to be the whole answer to the rabit problem.

Rabits continue to damage crops and pastures in many areas and resurgences of rabbit populations are reported from time to time.

Drs D.R. King and S. H. Wheeler of the Agricultural Protection Board's research section have been studying the way myxomatosis epidemics occur and spread in rabbit populations in a range of Western Australian environments. This research will provide data for planning effective control strategies intergrating the various control options available …


Dispelling Some Myths About 'Dermo', J R. Edwards Jan 1984

Dispelling Some Myths About 'Dermo', J R. Edwards

Journal of the Department of Agriculture, Western Australia, Series 4

There are a lot of misconceptions and myths about dermatophilosis, a disease which can kill young lambs, affect wool quality, make shearing difficult and make sheep susceptible to fly strike.

One misconception is perpetuated by the incorrect use of the name mycotic dermatitis, which implies that a fungus causes the disease. This is not so.

The disease is caused by the bacteria Dermatophilus congolensis, which attacks the sheep's skin and eventually forms a lesion or scab in the wool, and so is better called dermatophilosis, 'dermo' or 'lumpy wool'.

Veterinary Epidemiologist at the Albany Regional Office, J.R. Edwards, discusses …


Enteric Redmouth Disease Of Salmonids, G. L. Bullock Jan 1984

Enteric Redmouth Disease Of Salmonids, G. L. Bullock

United States Fish and Wildlife Service: Publications

Enteric redmouth disease (ERM) is a systemic bacterial infection of fishes, but is principally known for its occurrence in rainbow trout, Salmo gairdneri. The disease was first reported in the 1950's by Rucker (1966), and in recognition of that fact, the causal organism was named Yersinia ruckeri by Ewing et al. (1978). Although Wagner and Perkins (1952) described a bacterial disease that produced a red-mouth condition in rainbow trout in California and Colorado, it was caused by a different bacterium; they isolated Pseudomonas hydrophila rather than Y. ruckeri.


Alcataenia Campylacantha (Krabbe, 1869) From Pigeon Guillemots, Cepphus Columba Pallas, And Black Guillemots, Cepphus Grylle (Linnaeus), And Alcataenia Sp. Indet. (Cestoda: Dilepididae) From Kittlitz's Murrelets, Brachyramphus Brevirostris (Vigors) In Alaska, Eric P. Hoberg Jan 1984

Alcataenia Campylacantha (Krabbe, 1869) From Pigeon Guillemots, Cepphus Columba Pallas, And Black Guillemots, Cepphus Grylle (Linnaeus), And Alcataenia Sp. Indet. (Cestoda: Dilepididae) From Kittlitz's Murrelets, Brachyramphus Brevirostris (Vigors) In Alaska, Eric P. Hoberg

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Alcataenia campylacantha (Krabbe, 1869) is redescribed and reported for the first time from pigeon guillemots, Cepphus columba Pallas, in Alaska. Specimens of this cestode were also found in black guillemots, Cepphus grylle (Linnaeus) at Point Barrow, Alaska. There were no substantial differences in morphological characters between populations of this cestode from the North Atlantic and North Pacific basins. Additionally, Alcataenia sp. indet. is reported, with a partial description, from Kittlitz's murrelets, Brachyramphus brevirostris (Vigors), in Alaska. This constitutes the first record of dilepidid cestodes from birds of the genus Brachyramphus Brandt.

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Alcataenia longicervica sp. n. (Cestoda: Dilepididae) is described from murres, Uria spp., in Alaska and other localities in the Pacific basin. From Alcataenia armillaris (Rudolphi, 1810), which it most closely resembles, A. longicervica is distinguished by larger size of organs (cirrus sac, vitelline gland, and seminal receptacle), greater number of testes, and extremely long neck. In specimens of A. longicervica there are 22-27 rostellar hooks distributed in two rows. Hooks in the anterior row measure 41-49 μm in length while those in the posterior are 38-48 μm. Two species of Alcataenia, A. armillaris and A. meinertzhageni (Baer, 1956), both …


Trematode Parasites Of Marine Birds In Antarctica: The Distribution Of Gymnophallus Deliciosus (Olsson 1893), Eric P. Hoberg Jan 1984

Trematode Parasites Of Marine Birds In Antarctica: The Distribution Of Gymnophallus Deliciosus (Olsson 1893), Eric P. Hoberg

Harold W. Manter Laboratory of Parasitology: Faculty Publications

During continuing studies of avian helminths at Palmer Station, Antarctica (Hoberg 1983) trematodes were found as parasites only of charadriiform birds. Digeneans were not represented in extensive collections (including several thousand specimens of helminths) from spheniscids, procellariids, and phalacrocoracids.

The pattern of distribution of trematodes in marine birds in Antarctica is influenced by the availability of suitable intermediate hosts (mollusca) and the foraging behavior of potential final hosts. Littoral environments near Palmer are structurally simple and of low diversity due to ice scouring. The limpet, Nacella polaris, is the dominant intertidal invertebrate and one of the few molluscs that …


Angularella Audubonensis Sp. N. (Dilepididae) And Other Cestodes Of Cliff Swallows In Colorado, Jeffrey D. Stamper, Gerald D. Schmidt Jan 1984

Angularella Audubonensis Sp. N. (Dilepididae) And Other Cestodes Of Cliff Swallows In Colorado, Jeffrey D. Stamper, Gerald D. Schmidt

Harold W. Manter Laboratory of Parasitology: Faculty Publications

One hundred forty-five cliff swallows, Petrochelidon pyrrhonota, were examined for cestodes in two separate surveys in Weld County, Colorado. Seven species representing four genera were found. Angularella audubonensis sp. n. is differentiated by the small size of the rostellar hooks (8.4-13.5 μm) and the medial relationship of the cirrus pouch to the osmoregulatory canals. Other species collected were Angularella beema, Anonchotaenia globata, Mayhewia ababili, Vitta magniuncinata, Vitta parvirostris and Vitta riparia. Seven new hosts and geographic distribution records were established for Colorado, and six new records were determined for North America.


A Checklist Of Parasites Of California, Oregon, And Washington Marine And Estuarine Fishes, Milton S. Love, Mike Moser Dec 1983

A Checklist Of Parasites Of California, Oregon, And Washington Marine And Estuarine Fishes, Milton S. Love, Mike Moser

Harold W. Manter Laboratory of Parasitology: Faculty Publications

This report is a summary of the published records of parasites found from the marine and estuarine fishes of California, Oregon, and Washington. Coverage has not been limited to the western United States, but rather includes parasite reports from throughout each fish's range. Included is a host-parasite list and parasite-host cross index.

We have produced this survey because we felt there was a need for a single source which would list all the parasites infecting marine and estuarine fish from California, Oregon, and Washington. Pertinent sources are scattered over a number of journals, covering many years. Workers find it time …


Prostaglandin F2a Induced Nest Building Behavior In The Non-Pregnant Sow, And Some Welfare Considerations, Judith K. Blackshaw Jan 1983

Prostaglandin F2a Induced Nest Building Behavior In The Non-Pregnant Sow, And Some Welfare Considerations, Judith K. Blackshaw

International Journal for the Study of Animal Problems

Nest-building behavior, induced with intramuscular injections of prostaglandin F2a (PGF2a), was studied in non-pregnant sows. Acute effects were also recorded, including salivation, scratching, vomiting, defecation, and ataxia. Sows (Large White x Landrace) were housed in two different environments; six in bare pens and six in pens provided with bedding material. All cases except one (bare pen) nest-building sequences of differing intensities were recorded. Welfare suggestions include questioning the justification of using a drug (PGF2a) in pig husbandry, which has unpleasant acute effects, and the suggestion that the provision of bedding material is not necessary for a nest-building sequence to occur.

Infectious Pancreatic Necrosis (Ipn) Of Salmonid Fishes, Phillip E. Mcallister Jan 1983

Infectious Pancreatic Necrosis (Ipn) Of Salmonid Fishes, Phillip E. Mcallister

United States Fish and Wildlife Service: Publications

Infectious pancreatic necrosis (IPN) is a viral disease principally associated with salmonids, although IPN and lPN-like viruses have been isolated from various nonsa1rnonid fish and marine invertebrates. Acute infection occurs in 1- to 4-month-old salmonids and can result in cumulative mortality approaching 100%. In contrast, fish 6 months old or older can undergo subclinical or inapparent infection, but experience no significant mortality. Survivors of the disease can become lifelong carriers of the virus. Epizootics of IPN have been reported worldwide, and several virus serotypes are recognized. The disease known as IPN was probably first described by M'Gonigle (1941) as acute …


Cranes Of The World: 7. Endangered Species And Conservation, Paul A. Johnsgard Jan 1983

Cranes Of The World: 7. Endangered Species And Conservation, Paul A. Johnsgard

Cranes of the World by Paul A. Johnsgard

Few families of birds, other than some associated with small island archipelagos, have such a large proportion of their species in danger of extinction as does the crane family. Of the 14 extant species of cranes, King (1979) regards two full species (whooping crane and Siberian crane) as endangered, three more (Japanese, hooded, and white-naped) as vulnerable, and the black-necked crane as of indeterminate status. Additionally, one race (the Mississippi) of the sandhill crane is classified as endangered, and the Cuban race is regarded as rare and local. Thus, more than a third of the world's crane species are currently …


Gastrointestinal Helminths Of The Cougar, Felis Concolor L., In Northeastern Oregon, Robert L. Rausch, C. Maser, Eric P. Hoberg Jan 1983

Gastrointestinal Helminths Of The Cougar, Felis Concolor L., In Northeastern Oregon, Robert L. Rausch, C. Maser, Eric P. Hoberg

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Helminths of nine species were identified from 39 cougars obtained in northeastern Oregon (Walbowa, Baker, and Union counties), viz., Taenia omissa Lühe, 1910 (100%); T. ovis krabbei Moniez, 1879 (61%); T. hydatigena Pallas, 1776 (10%); Mesocestoides lineatus (Goeze, 1782) (5%); Toxascaris leonina (von Linstow, 1902) (69%); Toxocara cati (Schrank, 1788) (15%); Physaloptera praeputialis von Linstow, 1889 (13%); Pterygodermatites affinis (Jagerskiold, 1904) (ca. 2%); and Trichinella sp. (larvae) (ca. 2%). In addition, undeveloped cestodes of the genus Taenia in 26 animals had lost rostellar hooks and could not be identified. Host-records, prevalence, and biological characteristics of some of the helminths are …

Monoclonal Antibodies To Novel Myeloid Antigens Reveal Human Neutrophil Heterogeneity., Edward D. Ball, Robert F. Graziano, Li Shen, Michael W. Fanger Sep 1982

Monoclonal Antibodies To Novel Myeloid Antigens Reveal Human Neutrophil Heterogeneity., Edward D. Ball, Robert F. Graziano, Li Shen, Michael W. Fanger

Dartmouth Scholarship

Three cytotoxic murine monoclonal antibodies that recognize myeloid-specific antigens have been produced by immunization with normal human neutrophils or myeloblasts from a patient with acute myelomonocytic leukemia. Two of these, PMN 6 and PMN 29, are specific for neutrophils; the third monoclonal antibody, AML-2-23, is reactive with the majority of normal monocytes as well as a subpopulation of mature neutrophils. Although neutrophils from all individuals tested expressed these antigens, cytofluorographic analysis revealed that the percentage of cells bearing the PMN 6 and AML-2-23 antigens varied among individuals. Significant additional heterogeneity in the density of each antigen among antigen-bearing cells was …


Evidence For The Horizontal Acquisition Of Murine Akr Virogenes By Recent Horizontal Infection Of The Germ Line, Stephen J. O'Brien, Janet L. Moore, Malcolm A. Martin, James E. Womack Apr 1982

Evidence For The Horizontal Acquisition Of Murine Akr Virogenes By Recent Horizontal Infection Of The Germ Line, Stephen J. O'Brien, Janet L. Moore, Malcolm A. Martin, James E. Womack

Biology Faculty Articles

Several recent reports have established the biological and molecular genetic similarity between the endogenous AKV virus of strain AKR, and an N-ecotropic endogenous virus found in the genome of feral Japanese mice, Mus musculus molossinus. The similarities are so striking as to suggest a common origin of these viruses, which are present in some, but not all, inbred mouse strains. The virogenes of AKR mice may have been acquired by either: (a) common descent of AKR (and other AKV+ strains) from a common ancestor of AKR and molossinus animals, or (b) horizontal germ line infection of the AKR …


Electrophoretic And Immunological Studies On The Relationship Of The Brachyphyllinae And The Glossophaginae, Robert J. Baker, Rodney L. Honeycutt, Michael L. Arnold, Vincent M. Sarich, Hugh H. Genoways Nov 1981

Electrophoretic And Immunological Studies On The Relationship Of The Brachyphyllinae And The Glossophaginae, Robert J. Baker, Rodney L. Honeycutt, Michael L. Arnold, Vincent M. Sarich, Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

Electrophoretic and albumin immunological data indicate that the Brachyphyllinae as currently conceived is a natural assemblage, with Erophylla sezekorni and Phyllonycteris aphylla being more closely related to each other than either is to Brachyphylla cavernarum. In both data sets, values that distinguish Erophylla from Phyllonycteris are in the general range of values that characterize congeneric species of mammals. Immunological distance values for the species Glossophaga soricina, Monophyllus redmani, Anoura caudifer, Leptonycteris sanborni, Choeroniscus minor, and Hylonycteris underuoodi indicate that these taxa are approximately equidistant from the Brachyphyllinae. Immunological comparisons of Glossophaga and Monophyllus to Anoura, Leptonycteris, Choeroniscus, …


Key To Trematodes Reported In Waterfowl, Malcolm Edwin Mcdonald Sep 1981

Key To Trematodes Reported In Waterfowl, Malcolm Edwin Mcdonald

Harold W. Manter Laboratory of Parasitology: Library Materials

This key is the second in a series for identification of the helminths reported in waterfowl (Family Anatidae, Order Anseriformes). The first was a key to nematodes (McDonald 1974).

The trematodes show the greatest variety of forms among the helminth parasites of waterfowl, including over half of all species reported; sometimes this group also includes the greatest part of the worms in a single bird. Over 500 species of trematodes have been reported in waterfowl. Almost all of these have been included in the present set of keys; it was not possible, however, to obtain the descriptions of a few …

Incorporation Of Carbon-14 Metabolites Into The Sex Pheromon 26-Dichlorophenol Of Dermacentor Andersoni Stiles; And The Disruption Of Pheromone Activity In D. Andersoni And D. Variabilis (Say) By Quinones, Daniel Martin Gainsburg Apr 1981

Incorporation Of Carbon-14 Metabolites Into The Sex Pheromon 26-Dichlorophenol Of Dermacentor Andersoni Stiles; And The Disruption Of Pheromone Activity In D. Andersoni And D. Variabilis (Say) By Quinones, Daniel Martin Gainsburg

Biological Sciences Theses & Dissertations

The Rocky Mountain wood tick, Dermacentor andersoni Stiles, injected with (u-14c) sodium acetate or DL-(benzene ring-u-14c) tryptophan for in vivo studies, was found to produce sex pheromone, 2,6-dichlorophenol, containing 14c activity. Ambiguous results were obtained with L-(u- 14c) tyrosine, and no incorporation of 14c label into pheromone was observed with DL-(ring-u- 14c) phenylalanine or DL-(side chain-3-14c) tyrosine. Attempts were made to determine the site of synthesis, but in vitro studies proved inconclusive.

Disruption of sex pheromone activity in D. andersoni and the American dog tick, D. variabilis (Say) was achieved …


Breeding And Use Of Nonhuman Primates In The Usa, Joe R. Held Jan 1981

Breeding And Use Of Nonhuman Primates In The Usa, Joe R. Held

International Journal for the Study of Animal Problems

Several species of nonhuman primates, each possessing specific characteristics of particular value, are used by the United States biomedical community in various health-related activities. These animals are man's closest relatives and are indispensable in understanding and controlling human health problems. The destruction of primate habitats and embargoes on the export of primates from source countries have decreased the supply of these animals. The inadequate and erratic supply of these resources threatens the continuation of many ongoing and new activities contributing to improving human health. In the U.S., a program has been developed to meet the health needs of primates:

Gastrointestinal Cestodes And Nematodes Of Coyotes From Southeastern Illinois, Valerie Keener Jan 1981

Gastrointestinal Cestodes And Nematodes Of Coyotes From Southeastern Illinois, Valerie Keener

Masters Theses

Gastrointestinal tracts of 45 coyotes, Canis latrans, from southeastern Illinois were examined for cestodes and nematodes. The following parasites and incidences (%) were observed: Taenia sp. (71.1); Physaloptera sp. (53.3); Ancylostoma sp. (20.0); Ascarididae (11.1); Thelazia sp. (2.2); Trichuris sp. (2.2); Uncinaria sp. (2.2). Ancylostoma sp. occurred significantly more often in juveniles than adults. Parasites averaged low numbers per coyote, and no ulceration or blood in the tracts was seen.
