The financial support of Australian Wool Innovation Ltd (AWI) made it possible for representatives of a range of organisations from across Australia to meet and review ovine footrot. This national workshop held in Perth in August 2003, was the first of its kind for several years and brought together senior researchers, policy makers and producers from all States. The workshop provided an opportunity for the varied approach to footrot control across Australia to be considered in terms of a national approach to footrot control and also for individual States to review their current strategies in the light of experiences in …

Ionizing Radiation And Endostatin Gene Therapy Against Lung Tumor, Xian Luo

Loma Linda University Electronic Theses, Dissertations & Projects

Although many advances have been made in radiotherapy, tumor radioresistance and normal tissue damage continue to always be important issues for radiation oncologists. Numerous reports have also documented that radiation exposure increases the risk for malignancy and suppresses immune mechanisms. However, increasing evidence has suggested that anti-angiogenic therapy that targets tumor blood supply may alter abnormal tumor vasculature, thus synergizing radiotherapy. The governing hypothesis of the present study was that modification of tumor vasculature by antiangiogenic gene therapy can increase the efficacy of radiotherapy and that radiation can also improve DNA transfection efficiency by increasing expression of the administered gene. …

Genetic Analysis Of The Putative Streptolysin O Regulator From Streptococcus Pyogenes, Robert Tyrone Billingslea

McCabe Thesis Collection

Group A streptococci (Streptococcus pyogenes) is one of the most frequent pathogens of humans. It is estimated that between 5-15% of normal individuals harbor the bacterium, usually in the upper respiratory tract, without signs of disease. S. pyogenes can initiate an active infection when defenses are compromised or when the organism is able to penetrate the host's defenses. When the bacteria invade vulnerable tissues, a variety of suppurative infections can occur. Acute S. pyogenes infection may be present as pharyngitis ("strep throat"), scarlet fever (rash), impetigo (infection of the superficial layers of the skin) or cellulitis (infection of the deep …

Association Study Of The Angiotensin-Converting Enzyme (Ace) Gene G2350a Dimorphism With Myocardial Infarction, M Perwaiz Iqbal, Saeed Mahmood, Naseema Mehboobali, Mohammad Ishaq, Tasnim Fatima, Saddiqa Parveen, Philippe Frossard

Department of Biological & Biomedical Sciences

The angiotensin converting enzyme (ACE) is a strong candidate gene for myocardial infarction (MI). Insertion-deletion dimorphism in intron 16 of this gene has been inconclusively found to be associated with it. Several new polymorphisms in the ACE gene have been identified and among these, a dimorphism in exon 17, ACE G2350A, has a significant effect on plasma ACE concentrations. To assess the value of genotyping the ACE G2350A dimorphism in a genetically homogeneous population, we carried out a case-control study of dimorphism G2350A for a putative association with MI among Pakistani nationals. We investigated a sample population of 370 Pakistanis, …

A 22 question demographic instrument was used for background information, and an 18 question multiple-choice assessment was used to assess knowledge of prevention, recognition and management of EIA. A panel of experts reviewed and modified the survey instruments, which were piloted at a local private high school prior to distribution. The survey was distributed to 250 high school coaches in the Hampton Roads area during a fall …

A Survey Into The Prevalence Of Parasitic Helminths In Boiler Breeders, Anita Sarathi

Inquiry: The University of Arkansas Undergraduate Research Journal

A survey was conducted to determine the prevalence of helminth infections in spent broiler breeders. Intestinal tracts from 10 birds from each of five farms were obtained and examined for parasite identification and quantification. Heterakis gallinarum infections were the most common, followed in order of decreasing incidence by Capillaria obsignata, Ascaridia galli and Raillietina cesticillus. Peak worm burdens for individual birds were 121 (A. galli), 535 (H. gallinarum), 2I5 (C. obsignata) and 125 ( R. cesticillus). Significant farm-to-farm variation in worm burdens was observed.

Facts About Footrot - A Special Booklet For Neighbours Of Properties Which Have Been Quarantine For Footrot, Or Farmers Wanting To Know More About Footrot, Department Of Agriculture, Western Australia

Animal production and livestock published reports

Footrot is a contagious disease of sheep and goats caused by a mix of different bacteria, with the essential one being Dichelobacter nodosus. The bacterial infection can cause varying degrees of damage to the horn of the foot, leading to lameness, and significant loss of body weight and wool production.

There are two main forms of footrot - virulent and benign. Both are caused by D. nodosus. Footrot is diagnosed using two methods; inspecting sheep's feet, and testing skin scrapings in the laboratory

Human Rabies Post-Exposure Treatment In Arkansas, 1994-2000, D. Blake Sasse

Journal of the Arkansas Academy of Science

The Arkansas Department of Health recorded 118 incidents where humans in Arkansas were treated following exposure to confirmed rabid animals from 1994-2000. Domestic species accounted for 64% of incidents and 76% of total human exposures with the ratio of human exposures per rabid animal 17 times higher for domestic animals than wild animals. Records of 218 cases of human exposure to potentially rabid wild animals during this period were also examined to determine method of contact. While 72% of cases involving raccoons (Procyon lotor), skunks (Mephitis mephitis and Spilogale putorius), and foxes (Urocyon cinereoargenteus and Vulpes vulpes) were initiated by …

Evaluating The Disparity Of Female Breast Cancer Mortality Among Racial Groups - A Spatiotemporal Analysis, Chiehwen E. Hsu, Holly Jacobson, Francisco Soto Mas

Faculty, Staff and Student Publications

Background The literature suggests that the distribution of female breast cancer mortality demonstrates spatial concentration. There remains a lack of studies on how the mortality burden may impact racial groups across space and over time. The present study evaluated the geographic variations in breast cancer mortality in Texas females according to three predominant racial groups (non-Hispanic White, Black, and Hispanic females) over a twelve-year period. It sought to clarify whether the spatiotemporal trend might place an uneven burden on particular racial groups, and whether the excess trend has persisted into the current decade.

Methods The Spatial Scan Statistic was employed …

Evaluation Of Immunogenicity Of Transgenic Chloroplast Derived Protect, Vijay Koya

Electronic Theses and Dissertations

Anthrax, a fatal bacterial infection is caused by Bacillus anthracis, a gram-positive, spore forming, capsulated, rod shaped organism. Centers for Disease Control (CDC) lists anthrax as Category A biological agent due to its severity of impact on human health, high mortality rate, acuteness of the disease and potential for delivery as a biological weapon. The currently available human vaccine in the United States (AVA anthrax vaccine adsorbed) is prepared from Alum adsorbed formalin treated supernatant culture of toxigenic, non-encapsulated strain of Bacillus anthracis with the principle component being protective antigen (PA83). Evaluation of anthrax vaccine given to nearly 400,000 US …

Potential Mechanisms Explaining The Antitumor Effect Of Total-Body Irradiation, Glen Michael Miller

Loma Linda University Electronic Theses, Dissertations & Projects

While numerous reports have documented that radiation exposure increases the risk for malignancy and suppresses immune mechanisms, increasing evidence has suggested that low-dose total-body irradiation (TBI) may alter leukocyte composition and function leading to heightened immune responsiveness and long-term remission of certain cancers. Having observed that moderate-dose TBI produces an antitumor effect in the Lewis lung carcinoma (EEC) model, the major goal of this study was to determine whether changes in tumor growth could be correlated with radiation-induced alterations of immune system parameters. The governing hypothesis was that selective immune augmentation, i.e. upregulation of specific leukocyte subsets, is primarily responsible …

Photodynamic Therapy, Ashley Thomas

McCabe Thesis Collection

Photodynamic therapy is a new treatment that is being introduced into the veterinary community. Photodynamic therapy is the use of light activated chemotherapy to kill cancer cells (Dougherty, 1998). It has already been approved by the US Food and Drug Administration to be used as a form of cancer treatment in humans, but has not been carried over to the veterinary community. That is until now. Photodynamic therapy is now being tested in the veterinary community in hopes to find the same results that the human medical community has when dealing with certain types of cancer. They also hope to …

The Short-Term Effects Of Grade 1 And 2 Joint Mobilizations On Subject Pain Range Of Motion And Muscle Activity In The Pathological Lumbar Spine, Sean Hanrahan

The purpose of this study was to examine the short-term effects of Grades 1 and 2 posteroanterior joint mobilizations (JM) at the pathological lumbar spine on subject pain, range of motion (ROM), and muscle force. All subjects were determined to have sustained mechanical dysfunction of the lumbar spine of less than 48 hours as assessed through a standardized evaluation. Subjects were randomly assigned to a group; the control group received ice and stretching while the experimental group received JM in addition to ice and stretching. The JM's were performed at 3 consecutive lumbar segments surrounding the area of greatest discomfort. …

The Ecological Ramifications Of Disease And Density In The Caribbean Spiny Lobster, Panulirus Argus, Donald C. Behringer Jr.

Biological Sciences Theses & Dissertations

In 1999, I discovered the first virus known to be pathogenic to any species of lobster. HLV-PA is a pathogenic herpes-like virus that infects juvenile Caribbean spiny lobster, Panulirus argus, in the waters off south Florida (USA), and it alters the behavior and ecology of this species in fundamental ways. Gross signs of HLV-PA infection are lethargy, morbidity, cessation of molting, and discolored, “milky” hemolymph that does not clot. HLV-PA infects the hemocytes of host lobsters, specifically the hyalinocytes and semi-granulocytes, but not the granulocytes. When hemolymph from infected donors was injected into healthy juvenile lobsters, 90% of the …

Enterobius Vermicularis: Ancient Dna From North And South American Human Coprolites, Alena M. Iñiguez, Karl J. Reinhard, Adauto Araújo, Luiz F. Ferreira, Ana Carolina P. Vicente

School of Natural Resources: Faculty Publications

A molecular paleoparasitological diagnostic approach was developed for Enterobius vermicularis. Ancient DNA was extracted from 27 coprolites from archaeological sites in Chile and USA. Enzymatic amplification of human mtDNA sequences confirmed the human origin. We designed primers specific to the E. vermicularis 5S ribosomal RNA spacer region and they allowed reproducible polymerase chain reaction identification of ancient material. We suggested that the paleoparasitological microscopic identification could accompany molecular diagnosis, which also opens the possibility of sequence analysis to understand parasite-host evolution.

Meiotic And Mitotic Phenotypes Conferred By The Blm1-1 Mutation In Saccharomyces Cerevisiae And Msh4 Suppression Of The Bleomycin Hypersusceptibility, Georgia Anyatonwu, Ediberto Garcia, Ajay Pramanik, Marie Powell, Carol Wood Moore

Publications and Research

Oxidative damage can lead to a number of diseases, and can be fatal. The blm1-1 mutation of Saccharomyces cerevisiae confers hypersusceptibility to lethal effects of the oxidative, anticancer and antifungal agent, bleomycin. For the current report, additional defects conferred by the mutation in meiosis and mitosis were investigated. The viability of spores produced during meiosis by homozygous normal BLM1/BLM1, heterozygous BLM1/blm1-1, and homozygous mutant blm1-1/blm1-1 diploid strains was studied and compared. Approximately 88% of the tetrads derived from homozygous blm1-1/blm1-1 mutant diploid cells only produced one or two viable spores. In contrast, just one tetrad among all BLM1/BLM1 and BLM1/blm1-1 …

Experimental Channel Catfish Virus Infection Mimics Natural Infection Of Channel Catfish, Robin L. Stingley, Wayne L. Gray, Billy R. Griffin, Reid Landes

Journal of the Arkansas Academy of Science

Channel catfish virus (CCV) causes a severe hemorrhagic disease in channel catfish fry and fingerlings. CCV epizootics are associated with elevated water temperatures and high mortality rates. Survivors of acute disease are latently infected with i virus. In this study, we investigated conditions effecting CCV pathogenesis and latency utilizing an experimental immersion model to simulate natural infection and a population of Arkansas catfish verified to have no prior CCV exposure, the results indicate that the Auburn- 1 laboratory strain is comparable to CCV field isolates in virulence and ability to establish latent infection. The study confirms that water temperature and …

The Effects Of Classic And Variant Infectious Bursal Disease Viruses On Lymphocyte Populations In Specific-Pathogen-Free White Leghorn Chickens, Christina L. Johnson, Ashley K. Cox, April D. Keeter, Will J. Quinn, Gisela F. Erf, Lisa A. Newberry

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Infectious bursal disease virus (IBDV) is a pathogen that primarily infects B lymphocytes in domestic avian species. This viral infection has been associated with immunosuppression, clinical disease/mortality, and enteric malabsorption effects. The purpose of this experiment was to compare the effects of a classic (USDA-STC) and a new variant IBDV (RB-4, known to induce primarily the enteric disease) on immune cell populations in lymphoid organs. Seventeen-day-old specific-pathogen-free (SPF) White Leghorn chickens were either not infected (control) or inoculated with either USDA-STC or RB-4 IBD viral isolate. On days 3 and 5 post-inoculation (PI), lymphoid tissues were collected to prepare cell …

Regulation Of Proto-Oncogenes Expression In Developmental Epilepsy, Mahnoush Shafiei

Seton Hall University Dissertations and Theses (ETDs)

Seizures cause selective neuronal cell loss in vulnerable regions such as the hippocampus, cortex, thalamus or substantia nigra (SN) in human or experimental animals. While the HF can propagate seizures, the SN pars reticulata (SNR) regulates the spread ol seizures in an age-dependent fashion, and the pars compacta (SNC) affects extrapyramidal motor control. In mature animals, both structures are wlnerable to seizure-induced damage. In prepubescent rats, seizure susceptibility is reduced and CA 1 region rs primarily affected. The proto-oncogenes, Bcl-2 and Bax, encode specific proteins that inhibit and promote programmed cell death, respectively. In order to determine whether proto-oncogenes are …

Evidence For The Involvement Of A Tsetse Midgut Lectin-Trypsin Complex In Differentiation Of Bloodstream-Form Trypanosomes, L. U. Abubakar, G. Zimba, C. Wells, F. Mulaa, E. O. Osir

All Peer-Reviewed Publications

We have previously described a bloodmeal-induced molecule (lectin-trypsin complex) from the midgut of the tsetse fly, Glossina longipennis, with both lectin and trypsin activities (Osir et al., 1995). In this paper, we report on the isolation of a similar molecule from the midguts of Glossina fuscipes fuscipes and provide direct evidence for its involvement in the development of African trypanosomes. The molecule (native Mr ∼65,700) has two non-covalently linked subunits, Mr ∼28,800 and Mr ∼35,700. The native molecule was found to be capable of inducing differentiation of bloodstream-form trypanosomes into procyclic (midgut forms) in vitro. In the assays, specific antibodies …
