Glycoprotein K Specified By Herpes Simplex Virus Type 1 Is Expressed On Virions As A Golgi Complex-Dependent Glycosylated Species And Functions In Virion Entry, T. P. Foster, G. V. Rybachuk, K. G. Kousoulas

Faculty Publications

To facilitate detection of glycoprotein K (gK) specified by herpes simplex virus, a 12-amino-acid epitope tag was inserted within gK domain III. Recombinant virus gKprotC-DIII, expressing the tagged gK, was isolated. This virus formed wild-type plaques and replicated as efficiently as the wild-type KOS virus in Vero cells. Anti-protein C MAb detected high-mannose and Golgi complex-dependent glycosylated gK within cells as well as on purified virions. The gK-null virus ΔgK (gK-/-) entered Vero cells substantially more slowly than the wild-type KOS (gK+/+), while ΔgK virus grown in complementing VK302 cells (gK-/+) entered with entry kinetics similar to those of the …

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 …

Microscale Patchiness Of Bacterioplankton Assemblage Richness In Seawater, Richard A. Long, Farooq Azam

Faculty Publications

We sought to test the hypothesis that bacterial species richness and composition vary at the millimeter scale in the marine pelagic environment, in response to the heterogeneous distribution of organic matter. To test this hypothesis, it was necessary to design and test a protocol to sample, lyse and analyze (by polymerase chain reaction/denaturing gradient gel electrophoresis [PCR-DGGE]) bacterioplankton species richness in a single microliter of seawater. Significant variation in bacterial species richness was found amongst 1 μl samples. Greater species richness was seen when seawater was enriched with diatom detritus. Examination of species richness at 2 mm intervals over a …

Evaluation Of Directly Observed Therapy In Pulmonary Tuberculosis Patients In Nepal: Treatment Outcome And Patient Compliance, Baishali Bhattacharya

Masters Theses & Specialist Projects

Tuberculosis is the leading cause of infectious disease in Nepal. An estimated 60% of the adult population aged between 15-45 years is infected with tuberculosis, and 45% of the total population is infected. Ten percent of people infected with TB progress to active disease. To combat tuberculosis, Directly Observed Therapy (DOT) was adopted in Nepal in 1996. DOT was administered at four national demonstration sites in 1996 and expanded over time so that 56% of the population to date have been covered by DOT. This study aimed to evaluate DOT in pulmonary TB patients in Nepal in terms of patient …

The Effect Of Lead Acetate On The Susceptibility Of C3heb/Fej Mice Infected With The Parasite Trypanosoma Cruzi, Savonna Warren

Masters Theses & Specialist Projects

Lead has been mined by man for centuries with evidence of its use dating back 6000 years. Chronic exposure to lead can result in encephalopathy, anemia, and nephropathy. Today, cases of lead poisoning are uncommon; however, lead continues to be incorporated into the body through subclinical exposures. These low dosages of lead have been shown to have a deleterious effect on the immune system. Experimental animals exposed to low levels of lead are unable to effectively respond to a number of bacterial and viral challenges. The present study focuses on the relationship between lead and parasitic infection. Parasitemia, mortality, serum …

Effects Of Antioxidant Supplementation With Vitamin E And Selenium On Cytokine Production In Mice Infected With Trypanosoma Cruzi, Dong Chen

Masters Theses & Specialist Projects

Dietary supplementation with the antioxidants vitamin E and selenium (Se) has been shown to be beneficial against the intracellular parasite Trypanosoma cruzi during experimental Chagas' disease. Supplementation of mice with vitamin E and selenium at levels well above the recommended daily allowance for these two substances results in significantly decreased parasitemia levels and increased longevity. However, the mechanistic role of the antioxidants in this process is not well understood. It is known that vitamin E and selenium can reduce oxidative stress and improve host immune responses. In addition, the synthesis of many regulatory cytokines is known to be influenced by …

Fusobacteriosis In Captive Wild-Caught Pronghorns (Antilocapra Americana), J. F. Edwards, D. S. Davis, T. J. Roffe, F. Ramiro-Ibañez, P. H. Elzer

Faculty Publications

An outbreak of Fusobacterium necrophorum-induced septicemia occurred in a group of 40 captive wild-caught pronghorns (Antilocapra americana). Primary pododermatitis or necrotic stomatitis progressed to produce fatal septicemia with metastatic lesions in the forestomachs, lung, liver, and cecum in 38 of the animals. Two remaining animals were euthanatized because of chronic pododermatitis. Housing the animals in a pasture previously used by bovids and heavy rains with persistence of ground water pools in the pasture were contributing factors in the pathogenesis of this outbreak.

Immune Response Genes Modulate Serologic Responses To Vibrio Cholerae Tcpa Pilin Peptides, Michael D. Meeks, Terri K. Wade, Ronald K. Taylor, William F. Wade

Dartmouth Scholarship

Cholera is an enteric disease caused by Vibrio cholerae. Toxin-coregulated pilus (TCP), a type 4 pilus expressed by V. cholerae, is a cholera virulence factor that is required for host colonization. The TCP polymer is composed of subunits of TcpA pilin. Antibodies directed against TcpA are protective in animal models of cholera. While natural or recombinant forms of TcpA are difficult to purify to homogeneity, it is anticipated that synthesized TcpA peptides might serve as immunogens in a subunit vaccine. We wanted to assess the potential for effects of the immune response (Ir) gene that could complicate a peptide-based …

The aim of this study is to document the attitude of community pharmacists to fulfill the concept of pharmaceutical care and to evaluate how they manage a case of acute uncomplicated lower urinary tract infection. METHODS: Eighty-eight community pharmacists in the Eastern province of Saudi Arabia were presented with a patient claiming urinary tract infection and seeking medical treatment. RESULTS: Only one attendant pharmacist refused to dispense medications without prescription. Fifteen others (17%) dispensed urinary …

Bacteremia Associated With Early Childhood Caries, Eddie Chang

Loma Linda University Electronic Theses, Dissertations & Projects

Previous research has investigated the post-operative bacteria levels caused by a variety of clinical procedures such as anesthetic injections, standard dental procedures, endodontic treatment, periodontal surgery, root scaling, and oral surgical procedures in children. Other studies have suggested that bacteremias are often caused by oral infections. Although numerous studies have examined how oral infections lead to various medical conditions (i.e. brain abscess) none have studied the potential for preoperative bacteremia that may arise in conjunction with early childhood caries (ECC). The purpose of this study was to compare potential systemic facultative and anaerobic bacteria found in otherwise healthy children who …

Development Of A Model For Infective Endocarditis Via Intravenous Injection And Tooth Infection Of Rats Using Pathogenic Bacteria, Shahrokh Shabahang

Loma Linda University Electronic Theses, Dissertations & Projects

Historically, focal areas of infection have been linked to a number of systemic ailments. During the early part of the 20th century, patients who were suffering from inexplicable diseases and who were suspected of having infected teeth were referred to the dentist for multiple extraction of their dentition. The discovery of antibiotics provided a false sense of security that the war against microorganisms is no longer a concern for mankind. However, more recently, it has become common belief that increasing numbers of systemic diseases are linked to chronic infections. Recovery of bacteria from representative tissues has led investigators to believe …

Using An Importance-Performance Analysis Of Summer Students In The Evaluation Of Student Health Services., Candice Cline Duvernois

Electronic Theses and Dissertations

Hitherto, students have not evaluated the importance and performance of services provided by the student health service (SHS) at East Tennessee State University. An evaluation could provide valuable feedback to providers and administration.

In 2001, there were 944 student visits in the summer sessions. Approximately 256 students were offered a survey containing an Importance-Performance scale of which 151 (59.0%) responded. The I-P scale rates the importance students place on healthcare services and the performance of the SHS in delivering services (i.e., patient satisfaction).

Based on mean scores, students reported high importance, high performance on urgent care, pharmacy and patient education. …

Antibiotic Resistance: Multi-Drug Profiles And Genetic Determinants., Lashan Denise Taylor

Electronic Theses and Dissertations

Antimicrobial susceptibility profiles were assembled for isolates of Moraxella catarrhalis collected from the Mountain Home Veteran's Affairs Medical Center (VAMC) clinical laboratory in Johnson City, Tennessee. The goal of the study was to identify isolates for genetic characterization using comparisons of susceptibility profiles. Isolates of Moraxella catarrhalis collected from July 1984 through 1994 were analyzed for β-lactamase production using a Cefinase disk assay.

A multi-drug profile consisting of 11 β-lactam antibiotics was performed on the 41 M. catarrhalis isolates. Kirby Bauer disk assays were performed for 7 cephalosporin and 4 non-cephalosporin antibiotics.

In summary, 2 observations implicate more complex resistance …

Intracellular Signaling Molecules Activated By Epstein-Barr Virus For Induction Of Interferon Regulatory Factor 7, Luwen Zhang, Lihong Wu, Ke Hong, Joseph S. Pagano

Nebraska Center for Virology: Faculty Publications

Epstein-Barr virus (EBV) latent membrane protein 1 (LMP-1) is the principal oncogenic protein in the EBV transformation process. LMP-1 induces the expression of interferon regulatory factor 7 (IRF-7) and activates IRF-7 protein by phosphorylation and nuclear translocation. LMP-1 is an integral membrane protein with two regions in its C terminus that initiate signaling processes, the C-terminal activator regions 1 (CTAR-1) and CTAR-2. Here, genetic analysis of LMP-1 has determined that the PXQXT motif that governs the interaction between LMP-1 CTAR-1 and tumor necrosis factor receptor-associated factors (TRAFs) is needed to induce the expression of IRF-7. Mutations in the PXQXT motif …

Morphological And Molecular Description Of Haematoloechus Meridionalis N. Sp. (Digenea: Plagiorchioidea: Haematoloechidae) From Rana Vaillanti Brocchi Of Guanacaste, Costa Rica, Virginia León-Règagnon, Daniel R. Brooks, Derek A. Zelmer

Harold W. Manter Laboratory of Parasitology: Faculty Publications

An undescribed species of Haematoloechus inhabits the lungs of Rana vaillanti in northwestern Costa Rica. The new species is most similar morphologically to H. medioplexus, having a very small, but well-developed, ventral sucker and lacking extracecal uterine loops, and apparently was misidentified previously as H. medioplexus in Rana palmipes from Colombia. It differs from H. medioplexus, notably by (1) the shape of the oral sucker, which is elliptical in H. meridionalis and spherical in H. medioplexus; (2) the posterior extent of the vitelline fields, which terminate at the same level in H. medioplexus, but always at …

Evaluation Of A Tetracycline-Inducible Promoter In Staphylococcus Aureus In Vitro And In Vivo And Its Application In Demonstrating The Role Of Sigb In Microcolony Formation, B. T. Bateman, N. P. Donegan, T. M. Jarry, M. Palma

Dartmouth Scholarship

An inducible promoter system provides a powerful tool for studying the genetic basis for virulence. A variety of inducible systems have been used in other organisms, including pXyl-xylR-inducible promoter, the pSpac-lacI system, and the arabinose-inducible P_BAD promoter, but each of these systems has limitations in its application to Staphylococcus aureus. In this study, we demonstrated the efficacy of a tetracycline-inducible promoter system in inducing gene expression in S. aureus in vitro and inside epithelial cells as well as in an animal model of infection. Using the xyl/tetO promoter::gfp_uvr fusion carried on a shuttle …

Anti-Class Ii Monoclonal Antibody-Targeted Vibrio Cholerae Tcpa Pilin: Modulation Of Serologic Response, Epitope Specificity, And Isotype, Jia-Yan Wu, Ronald K. Taylor, William F. Wade

Dartmouth Scholarship

Toxin-coregulated pilus (TCP) is a colonization factor required for cholera infection. It is not a strong immunogen when delivered in the context of whole cells, yet pilus subunits or TcpA derivative synthetic peptides induce protective responses. We examined the efficacy of immunizing mice with TCP conjugated to anti-class II monoclonal antibodies (MAb) with or without the addition of cholera toxin (CT) or anti-CD40 MAb to determine if the serologic response to TcpA could be manipulated. Anti-class II MAb-targeted TCP influenced the anti-TCP peptide serologic response with respect to titer and isotype. Responses to TcpA peptide 4 were induced with class …
