Thermal Environmental Effects And Group Size On Growing Swine Immune Status, S.H. Pohl, D.J. Hurley, R.C. Thaler, C.C. Chase

South Dakota Swine Research Report, 2001

The effects of environmental conditions on the immune system of growing pigs (30-50 kg) were studied using T and B cell proliferation counts. Pigs were exposed to a constant 32°C ambient temperature versus a naturally occurring diurnal temperature variation during hot weather and a constant 10°C vs 21°C ambient temperature during cold weather. In addition, T and B cell proliferation counts were compared for pigs in single, 9 and 18 pigs/pen group sizes. Concancavalin A (ConA), Phytohemagglutinin (PHA) and Staphylococcal enterotoxin B (SEB) mitogens were used to determine T cell activation over time. Pokeweed (PWM), Lipopolysaccharide (LPS) and Salmonella typhimurium …

Avian Vacuolar Myelinopathy: A Newly Recognized Fatal Neurological Disease Of Eagles, Waterfowl And Other Birds, John R. Fischer, Lynn A. Lewis, Tom Augspurger, Tonie E. Rocke

United States Fish and Wildlife Service: Publications

Since 1994, wildlife biologists and wildlife health specialists have worked to determine the cause of avian vacuolar myelinopathy (AVM), a neurologic disease of bald eagles (Haliaeetus leucocephalus) and other birds. The causes of morbidity and mortality in wildlife typically are determined through both antemortem and postmortem examinations, combined with ancillary tests for microbiological organisms, toxicants and other etiologies. However, the etiology of AVM has not been determined yet, despite extensive diagnostic investigations, including examinations for common disease agents, as well as infrequent or unusual causes of mortality. With the failure of standard diagnostic testing to determine the cause …

United States Fish and Wildlife Service: Publications

"Prairie-dogs are distributed over a large part of the Great Plains and Rocky Mountain regions. Their colonies often number thousands of individuals, and their destruction of grasses and other forage plants makes them of considerable economic importance. Drastic measures are frequently necessary to prevent the destruction of crops of grain and hay. The Biological Survey is exterminating these rodents in national forests and in the public domain. The information in this report, in regards to the several species and their distribution, as indicated by maps, will aid materially in efforts, national or state, to control or exterminate them," said Henry …

Effects Of Pre-Milking Teat Sanitation On The Quality Of Raw Milk, Laurie Depiazzi, Ian Bell

Bulletins 4000 -

The effect of Quartermate pre-milking teat sanitation on milk quality was investigated in twelve dairy herds over a period of eight weeks. Pre-milking teat sanitation was carried out on all cows for six weeks on each of six farms and mesophile and thermophile bacteria counts of raw milks were compared before the milk line (“cluster” samples), and at various points within milking plants. Rates of mastitis, vat milk iodide levels and specific bacteria were also monitored.

Determination Of Protein Profile And Presence Of Antibodies In Llama Seminal Plasma (Llama Glama), Francisco Flores Lópes

Theses and Dissertations

Internationally, Bolivia has the largest llama population followed by Peru. This makes our country a power in this renewable resource for working and generating economic development. This is mainly because of the quality of llama meat, which has nutritional properties superior to other animal species. The development and research in our country of llamas is not very significant. But in other countries advanced studies have been done for years, specifically in the area of reproduction, which represents problems for intensive repopulation because of singular characteristics of semen and copulation. The present research work was done at the UAC in Tiahuanacu …

Morphological Variation Of Allocreadium Lobatum (Digenea: Allocreadiidae) In The Creek Chub, Semotilus Atromaculatus (Osteichthyes: Cyprinidae), In Nebraska, Usa, Monte S. Willis

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

Allocreadium lobatum Wallin 1909, a parasite of fresh-water fish, was originally described as having distinct lobate testes, and subsequent descriptions have left this original description unchanged. The present study quantifies the observation of distinctly non-lobate testes that could be categorized as round or asymmetrical in addition to the previously described lobate testes. Six hundred thirty-six A. lobatum were collected from 228 Semotilus atromaculatus over a 9 month period. Overall, 21.3%, 61.6%, and 16% were found to be round, asymmetrical, and lobate testes respectively (N = 1,071). Analysis of testis morphology found the increasing presence of lobate testis as …

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Development of the muskox protostrongylid lungworm, Umingmakstrongylus pallikuukensis, in its slug intermediate host, Deroceras laeve, was investigated under field conditions in the Arctic. Every two weeks, from 19 June to 28 August 1997, groups of ten experimentally infected slugs were placed in tundra enclosures in a mesic sedge meadow near Kugluktuk, Nunavut, Canada. First-stage larvae (L1) infecting slugs on or before 17 July developed to third-stage larvae (L3) in 4–6 weeks. Intensity of L3 in slugs peaked at 6–8 weeks post infection (PI) and then progressively declined by 10, 12, and 48–50 weeks PI. Abundance of L3 in …

A series of coumarin and pyranocoumarin analogues were evaluated in vitro for antiviral efficacy against measles virus (MV), strain Chicago. Of the 22 compounds tested for inhibition, six were found to have selectivity indices greater than 10. These were compounds 5-hydroxy-7-propionyloxy- 4-propylcoumarin (2a), 5,7-bis(tosyloxy)-4- propylcoumarin (7); 5-hydroxy-4-propyl-7-tosyloxy- coumarin (8); 6,6-dimethyl-9-propionyloxy-4- propyl-2H,6H-benzo[1,2-b:3,4-b′]dipyran-2-one (9); 6,6-dimethyl-9-pivaloyloxy-4-propyl-2H,6Hbenzo[ 1,2-b:3,4-b′]dipyran-2-one (10); and 7,8-cis- 10,11,12-trans-4-propyl-6,6,10,11-tetramethyl- 7,8,9-trihydroxy-2H,6H,12H-benzo[1,2-b:3,4-b′:5,6- b′′]tripyran-2-one (18). Three of the active drugs were propyl coumarin analogues (2a, 7 and 8), two were dipyranone or chromeno-coumarins (9 and 10), and one was a benzotripyranone with a coumarin nucleus (18). Some appeared to be rather specific and potent …

Production Of Transgenic Goats By Somatic Cell Nuclear Transfer, Brett C. Reggio

LSU Doctoral Dissertations

A series of experiments were conducted to produce transgenic goats by somatic cell nuclear transfer (NT). In all experiments, donor cells were electrically fused to enucleated metaphase II oocytes, then chemically activated. In a preliminary study to evaluate embryonic development following NT with proliferating or quiescent fibroblast or cumulus cells, significantly more embryos reconstructed with quiescent cumulus cells fused (77%) compared with proliferating cumulus cells (41%), proliferating fibroblasts (36%) or quiescent fibroblasts (37%). Improved development to the eight- to sixteen-cell stage was observed when fibroblast cells were serum starved (serum starved 39% vs. serum fed 15%). However, there was no …

Pine Needle Abortion – What We Know As Well As How To Predict/Prevent The Problem, Stephen P. Ford

Range Beef Cow Symposium

Pinus ponderosa or western yellow pine (Pinnace) is widely distributed in the U.S., but is most abundant in the Western U.S. and Western Canada. In the late 1920’s cattle stockmen and ranchers first suspected that ingestion of needles and buds from ponderosa pine trees caused an abortion. Original claims of ponderosa pine needles (PPN) being an abortifacient were discounted because of the many other known causes of abortions such as infectious diseases (brucellosis, leptospirosis), phosphorus and Vitamin A deficiencies. It wasn’t until 1952 that McDonald provided the first definitive evidence for a direct effect of a toxin in PPN needles …

The Mannose-Sensitive Hemagglutinin Of Vibrio Cholerae Promotes Adherence To Zooplankton, Deborah A. Chiavelli, Jane W. Marsh, Ronald K. Taylor

Dartmouth Scholarship

The bacterium Vibrio cholerae, the etiological agent of cholera, is often found attached to plankton, a property that is thought to contribute to its environmental persistence in aquatic habitats. The V. cholerae O1 El Tor biotype and V. cholerae O139 strains produce a surface pilus termed the mannose-sensitive hemagglutinin (MSHA), whereas V. cholerae O1 classical biotype strains do not. Although V. cholerae O1 classical does not elaborate MSHA, the gene is present and expressed at a level comparable to that of the other strains. Since V. cholerae O1 El Tor and V. cholerae O139 have displaced V. cholerae O1 classical …

Canine And Feline Parvoviruses Can Use Human Or Feline Transferrin Receptors To Bind, Enter, And Infect Cells, John S. L. Parker, William J. Murphy, Dai Wang, Stephen J. O'Brien, Colin R. Parrish

Biology Faculty Articles

Canine parvovirus (CPV) enters and infects cells by a dynamin-dependent, clathrin-mediated endocytic pathway, and viral capsids colocalize with transferrin in perinuclear vesicles of cells shortly after entry (J. S. L. Parker and C. R. Parrish, J. Virol. 74:1919–1930, 2000). Here we report that CPV and feline panleukopenia virus (FPV), a closely related parvovirus, bind to the human and feline transferrin receptors (TfRs) and use these receptors to enter and infect cells. Capsids did not detectably bind or enter quail QT35 cells or a Chinese hamster ovary (CHO) cell-derived cell line that lacks any TfR (TRVb cells). However, capsids bound and …

Investigations Into The Innate Resistance Of The Tick, Dermacentor Variabilis, When Challenged With The Bacterium, Escherichia Coli, Shane Michael Ceraul

Biological Sciences Theses & Dissertations

In addition to the soluble response, many invertebrates control bacterial infections by means of phagocytosis or melanotic encapsulation. In some insects, Escherichia coli growth is reported to be inhibited by aggregation/encapsulation. Soluble and phagocytic responses to bacterial challenge have been reported in ticks, but evidence of an aggregation/encapsulation response was reported only for inanimate (araldite) implants. This study was done to determine how ticks control infection by E. coli. Ticks were challenged by direct inoculation of bacteria into the hemocoel cavity. Using plate counts, no viable E. coli were detected I hour post-inoculation. A direct fluorescence assay (DF A) …

Re-Thinking The Summer Drenching Program, Brown Besier

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

The summer drenching program has provided highly effective sheep worm control in Western Australia for many years - but recent research challenges its long term sustainability.

Trial results suggest that in large parts of the State, summer drenching is the main factor leading to the development of drench resistant worms. Alternative programs less likely to lead to drench resistance will require greater monitoring of worm burdens and panning pasture moves.

Utilization Of Alpha-1-Acid Glycoprotein Levels In The Serum As A Parameter For In Vivoassay Of Influenza Virus Inhibitors. Antivir Chem Chemother, R. W. Sidwell, M. H. Wong, K. W. Bailey, Dale L. Barnard, M. K. Jackson, Donald F. Smee

Animal, Dairy, and Veterinary Science Faculty Publications

Alpha-1-acid glycoprotein (AGP), an acute phase protein in serum assayed by single radial immunodiffusion using a commercially available kit, was found to significantly increase in mice infected with influenza A and B viruses. Experiments were run to determine the rate of increase of serum AGP and its relation to other influenza disease parameters, including lung consolidation, development of lung virus titres, decline in arterial oxygen saturation (SaO2), histopathological changes in the lung, and death of the animal. Maximal AGP levels occurred by day 3 in the animals, at about the same time lung virus titres reached their peak and inflammatory …

New Host And Geographic Records For Two Protostrongylids In Dall's Sheep, Susan J. Kutz, A. M. Veitch, Eric P. Hoberg, B. T. Elkin, Emily J. Jenkins, L. Polley

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Biodiversity survey and inventory have resulted in new information on the distribution of Protostrongylidae in Dall’s sheep (Ovis dalli dalli) from the Northwest Territories (Northwest Territories, Canada) and from Alaska (Alaska, USA). In 1998, Parelaphostrongylus odocoilei adults were found for the first time in the skeletal muscles of Dall’s sheep in the Mackenzie Mountains (Northwest Territories). Adult P. odocoilei were associated with petechial and ecchymotic hemorrhages and localized myositis; eggs and larvae in the lungs were associated with diffuse granulomatous pneumonia. Experimental infections of the slugs Deroceras laeve and Deroceras reticulatum with dorsal-spined first-stage larvae assumed to be …

Onchocercosis In Red Deer (Cervus Elaphus) From Spain, Mónica Santín-Durán, José M. Alunda, Eric P. Hoberg

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Onchocercosis, caused by Onchocerca flexuosa, was observed in red deer (Cervus elaphus) from Spain for the first time. Adult specimens of O. flexuosa were found in nodules in subcutaneous tissues in 42 of 125 (33%) red deer between October 1994 and September 1995; intensity of infection 6 SD was 3.93 ± 5.26 nodules per infected host. A clear seasonal pattern in the distribution of nodules was observed, with higher values of prevalence and intensity in fall and winter in contrast to spring and summer. Significant differences were found among age groups in prevalence, but not in the …
