Turkish Journal of Veterinary & Animal Sciences

Small (1-3 µm in diameter, ring, oval, or comma shaped) piroplasms suggestive of Babesia spp. were observed upon microscopic examination of Giemsa-stained peripheral blood smears from a 3.5-year-old American Pit Bull Terrier with clinical signs of pyrexia, weakness, mucous membrane pallor, and depression living in Aydın, Turkey, in February, 2009. To confirm the presence and to identify the species of Babesia spp., a polymerase chain reaction (PCR) technique was performed using primers amplifying a 670 bp fragment of the 18S rRNA gene of Babesia gibsoni and the PCR products were analyzed by sequencing. The nucleotide sequence was compared to the …

Research Progress In China On The Virulence Factors Of Streptococcus Suis Serotype, Xiuwei Yue, Yixuan Hou, Xiuguo Hua, Shujie Wang, Zhibiao Yang, Xuehui Cai

Turkish Journal of Veterinary & Animal Sciences

Streptococcus suis serotype 2 (S. suis 2) is an important pathogen of zoonoses, which causes meningitis in pigs and represents a high health risk for humans related to porcine industry. Two outbreaks causing severe acute diseases in humans with high morbidity and mortality were reported in China, in 1998 and in 2005, respectively, which were clinically featured with streptococcal toxic shock syndrome. Some genes (or encoded products) were known as virulence factors, such as capsular polysaccharide, suilysin, muramidase-released protein, and extracellular factor. However, these were not enough to detect many potential cases of S. suis 2. Scientists in China have …

Turkish Journal of Veterinary & Animal Sciences

Canine leishmaniasis (CanL) is a severe, intracellular parasitic zoonosis and is an endemic complaint in Iran. Dogs are considered the reservoir host for Leishmania infantum in the Old World. The aims of this study were to evaluate the relation between anti-Leishmania antibody titers (IgG) and skin symptoms of CanL in naturally affected dogs and to assess the correlation of IgG_1 and IgG_2 subclasses of titers with these symptoms. Anti-Leishmania antibody titers were evaluated in 100 dogs' blood samples with the direct agglutination test (DAT) and enzyme-linked immunosorbent assay (ELISA) methods. Based on DAT results, 45 samples were positive. Twenty-five of …

Impact Of The Haberlea Rhodopensis Extract On The Innate Immune System And Response In Rabbits Following Klh-Hemocyanin Immunization And Cyclophosphamide Treatment, Svetlana Georgieva, Lilian Sotirov, Borislav Popov, Tsvetoslav Koynarski

Turkish Journal of Veterinary & Animal Sciences

The aim of the present investigation was to study the impact of Haberlea rhodopensis extract on the innate immune response in rabbits. The complement and lysozyme activity, percent phagocytosis, and phagocytic index were studied. The analysis of the results showed that the treatment with Haberlea rhodopensis extract, cyclophosphamide, and KLH renders a remittent effect upon the classical pathway of activation of the complement system and the lysozyme concentration in the rabbit blood serum. These same factors have no direct effect on the phagocytic activity in the investigated animals. The obtained data show limited effect of Haberlea rhodopensis extract on rabbits’ …

Clostridium Botulinum In Honey: Prevalence And Antibiotic Susceptibility Of Isolated Strains, Ahmet Koluman, Berfi̇n Meli̇koğlu Gölcü, Okan Deri̇n, Si̇bel Özkök, Fabrizio Anniballi

Turkish Journal of Veterinary & Animal Sciences

Clostridium botulinum and rare strains of C. butyricum and C. baratii produce an extremely potent toxin, the botulinum neurotoxin (BoNT). Infant botulism is significant for both its high mortality rates and for the sophisticated treatment that it requires. Isolation and identification of C. botulinum according to standards depend on mouse bioassays to determine toxin-producing ability of strains. Polymerase chain reaction (PCR) is used to detect the types of toxins expressed by bacteria. Since honey is an important source of infant botulism, we determined the types of toxins secreted by C. botulinum strains and their antibiotic resistance. In this study, the …

The AIDS era has seen multiple advances in the power of genetics research; scores of host genetic protective factors have been nominated and several have translated to the bedside. We discuss how genomics may inform HIV/AIDS prevention, treatment and eradication.

Protecting The Sanctity Of Human Life: The Catholic Church & Her Relationship With Hiv/Aids Prevention, Emma Joanne Burke

Master's Theses and Capstones

Though prevention is the most stressed component of the global fight against HIV/AIDS, global agreement regarding the most successful prevention method does not exist. For example, the majority of the medical and scientific community agrees that condoms and other safe-sex practices are the key to reducing the number of HIV transmissions, while the Catholic Church and her ranking officials claim that abstinence and monogamy are the only moral solutions.

This Thesis examines the policies of the Church, including her dedication to the protection of the sanctity of human life, in an attempt to determine if the Church's words are shaping …

Theory, Measurement And Hard Times: Some Issues For Hiv/Aids Research, Samuel R. Friedman, Milagros Sandoval, Pedro Mateu-Gelabert, Diana Rossi, Marya Gwadz, Kirk Dombrowski, Pavlo Smyrnov, Tetyana Basylyeva, Enrique R. Pouget, David Perlman

Department of Sociology: Faculty Publications

Economic and political instability and related “big events” are widespread throughout the globe. Although they sometimes lead to epidemic HIV outbreaks, sometimes they do not—and we do not understand why. Current behavioural theories do not adequately address these processes, and thus cannot provide optimal guidance for effective intervention. Based in part on a critique of our prior “pathways” model of big events, we suggest that cultural–historical activity theory (CHAT) may provide a useful framework for HIV research in this area. Using CHAT concepts, we also suggest a number of areas in which new measures should be developed to make such …

Surveillance And Movements Of Virginia Opossum (Didelphis Virginiana) In The Bovine Tuberculosis Region Of Michigan, W. D. Walter, J. W. Fischer, C. W. Anderson, D. R. Marks, T. J. Deliberto, S. Robbe-Austerman, K. C. Vercauteren

United States Department of Agriculture Wildlife Services: Staff Publications

Wildlife reservoir hosts of bovine tuberculosis (bTB) include Eurasian badgers (Meles meles) and brushtail possum (Trichosurus vulpecula) in the UK and New Zealand, respectively. Similar species warrant further investigation in the northern lower peninsula of Michigan, USA due to the continued presence of bTB on cattle farms. Most research in Michigan, USA has focused on interactions between white-tailed deer (Odocoileus virginianus) and cattle (Bos taurus) for the transmission of the infectious agent of bTB, Mycobacterium bovis, due to high deer densities and feeding practices. However, limited data are available on medium-sized mammals …

Evolutionary Characterization Of The Pandemic H1n1/ 2009 Influenza Virus In Humans Based On Non-Structural Genes, Chengmin Wang, Yanyu Zhang, Bin Wu, Shelan Liu, Ping Xu, Yanmin Lu, Jing Luo, Dale L. Nolte, Thomas J. Deliberto, Mingxing Duan, Hong Zhang, Hongxuan He

United States Department of Agriculture Wildlife Services: Staff Publications

The 2009 influenza pandemic had a tremendous social and economic impact. To study the genetic diversity and evolution of the 2009 H1N1 virus, a mutation network for the non-structural (NS) gene of the virus was constructed. Strains of the 2009 H1N1 pandemic influenza A virus could be divided into two categories based on the V123I mutation in the NS1 gene: G1 (characterized as 123 Val) and G2 (characterized as 123 Ile). Sequence homology analysis indicated that one type of NS sequence, primarily isolated from Mexico, was likely the original type in this pandemic. The two genotypes of the virus presented …

Wiidiife Translocation As A Management Alternative At Airports, Paul D. Curtis, Jonathon D. Cepek, Rebecca Mihalco, Thomas W. Seamans, Scott R. Craven

United States Department of Agriculture Wildlife Services: Staff Publications

Wildlife in urban settings may be a welcome sight for many, but negative interactions between people and various wild species are increasing (Conover et a!. 1995, Conover 2002). Wildlife populations are commonly managed in part to reduce these conflicts, particularly in high-risk areas such as roadways and airports (Conover 2002). However, the public often opposes lethal control or management methods perceived as causing harm to nuisance animals (Reiter et al. 1999, Conover 2002, Treves et al. 2006), and attitudes vary considerably depending on the particular wildlife species involved (Kretser et a!. 2009). Consequently, a variety of nonlethal management approaches are …

Wild Ungulates As Disseminators Of Shiga Toxin- Producing Escherichia Coli In Urban Areas, Alan B. Franklin, Kurt C. Vercauteren, Hugh Maguire, Mary K. Cichon, Justin W. Fischer, Michael J. Lavelle, Amber Powell, J. Jeffrey Root, Elaine Scallan

United States Department of Agriculture Wildlife Services: Staff Publications

Background: In 2008, children playing on a soccer field in Colorado were sickened with a strain of Shiga toxin-producing Escherichia coli (STEC) O157:H7, which was ultimately linked to feces from wild Rocky Mountain elk. We addressed whether wild cervids were a potential source of STEC infections in humans and whether STEC was ubiquitous throughout wild cervid populations in Colorado.

Methodology/Principal Findings: We collected 483 fecal samples from Rocky Mountain elk and mule deer in urban and non-urban areas. Samples testing positive for STEC were higher in urban (11.0%) than non-urban (1.6%) areas. Elk fecal samples in urban areas had a …

Glutaredoxin-2 Is Required To Control Proton Leak Through Uncoupling Protein-3, Ryan J. Mailloux, Jian Ying Xuan, Brittany Beauchamp, Marjorie F. Lou, Mary-Ellen Harper

School of Veterinary and Biomedical Sciences: Faculty Publications

Glutathionylation has emerged as a key modification required for controlling protein function in response to changes in cell redox status. Recently, we showed that the glutathionylation state of uncoupling protein-3 (UCP3) modulates the leak of protons back into the mitochondrial matrix, thus controlling reactive oxygen species production. However, whether or not UCP3 glutathionylation is mediated enzymatically has remained unknown because previous work relied on the use of pharmacological agents, such as diamide, to alter the UCP3 glutathionylation state. Here, we demonstrate that glutaredoxin-2 (Grx2), a matrix oxidoreductase, is required to glutathionylate and inhibit UCP3. Analysis of bioenergetics in skeletal muscle …

Accessory Genes Confer A High Replication Rate To Virulent Feline Immunodeficiency Virus, Ryan M. Troyer, Jesse Thompson, John H. Elder, Sue Vandewoude

School of Veterinary and Biomedical Sciences: Faculty Publications

Feline immunodeficiency virus (FIV) is a lentivirus that causes AIDS in domestic cats, similar to human immunodeficiency virus (HIV)/AIDS in humans. The FIV accessory protein Vif abrogates the inhibition of infection by cat APOBEC3 restriction factors. FIV also encodes a multifunctional OrfA accessory protein that has characteristics similar to HIV Tat, Vpu, Vpr, and Nef. To examine the role of vif and orfA accessory genes in FIV replication and pathogenicity, we generated chimeras between two FIV molecular clones with divergent disease potentials: a highly pathogenic isolate that replicates rapidly in vitro and is associated with significant immunopathology in vivo, …

Confronting Criminal Law’S Violence: The Possibilities Of Unfinished Alternatives, Allegra M. Mcleod

Georgetown Law Faculty Publications and Other Works

Confronting criminal law’s violence calls for an openness to unfinished alternatives — a willingness to engage in partial, in process, incomplete reformist efforts that seek to displace conventional criminal law administration as a primary mechanism for social order maintenance. But despite all indications that the status quo in U.S. criminal law administration is profoundly dysfunctional — an institutional manifestation of the deepest pathologies in our society — contemporary criminal law reform efforts and scholarship focus almost exclusively on relatively limited modifications to the status quo. These modifications may well render criminal law administration more humane, but fail to substitute alternative …

Towards A Framework Convention On Global Health: A Transformative Agenda For Global Health Justice, Lawrence O. Gostin, Eric A. Friedman

Georgetown Law Faculty Publications and Other Works

International law has responded weakly to the inequities in health care, public health, and the broader determinates of health that collectively cause the greatest loss of lives and human potential every year. Approximately one-third of global deaths can be attributed to enduring and unconscionable inequities. Despite significant progress in improving global health over the past several decades, these inequities persist. Current global governance for health is inadequate to the task of resolving these inequities, from lack of accountability and enforcement to inadequate funding and the absence of leadership required to respond to the threats to health that arise from other …

Viral Escape From Hiv-1 Neutralizing Antibodies Drives Increased Plasma Neutralization Breadth Through Sequential Recognition Of Multiple Epitopes And Immunotypes, Constantinos K. Wibmer, Jinal N. Bhiman, Elin S. Gray, Nancy Tumba, Salim S. Abdool Karim, Carolyn Williamson, Lynn Morris, Penny L. Moore

Research outputs 2013

Identifying the targets of broadly neutralizing antibodies to HIV-1 and understanding how these antibodies develop remain important goals in the quest to rationally develop an HIV-1 vaccine. We previously identified a participant in the CAPRISA Acute Infection Cohort (CAP257) whose plasma neutralized 84% of heterologous viruses. In this study we showed that breadth in CAP257 was largely due to the sequential, transient appearance of three distinct broadly neutralizing antibody specificities spanning the first 4.5 years of infection. The first specificity targeted an epitope in the V2 region of gp120 that was also recognized by strain-specific antibodies 7 weeks earlier. Specificity …

Shifting Local Ecologies: Biocultural Interactions And Ecuadorian Public Health, Sabrina Bradford

Honors Theses

Though biology is considered universal, this thesis argues against the assumption of the universal applications of biomedicine in favor of a biocultural approach, emphasizing shifting local ecologies in an increasingly globalized world. This research investigated Ecuadorian health within an ecological context in coordination with an international public health internship that was completed through the Universidad San Francisco de Quito and the Ecuadorian Ministerio de Salud Pública. Throughout this thesis, examples are provided demonstrating that globalization, though appearing as a homogenous process on the international level, creates heterogeneous effects on the local scale. To explain the mechanisms and implications of these …

Foraging Behavior, Habitat, Health, And Survival Of Resident And Translocated Hawaiian Monk Seals At Nihoa Island, Hawaii, Tenaya A. Norris

Master's Theses

Translocations aimed at promoting population recovery for threatened and endangered species also can function as forced dispersals. To assess the efficacy of translocating Hawaiian monk seals (Monachus schauinslandi) and examine post-dispersal effects on monk seals, in 2008-2009, 12 weanling seals were translocated from French Frigate Shoals (FFS) to Nihoa Island (NIH). In addition, nine adult and eight weanling resident seals were captured at NIH. Satellite instrument attachment, biological sampling, and morphometry were conducted on seals at capture. Focal video camera drops also were conducted at 45 sites around NIH (< 100 m) in 2010-2011. Translocated and resident weanlings primarily dove to 40-60 m and used sandy-bottomed habitat < 13 km from NIH. In contrast, resident adults had greater variability in foraging behavior and habitat use. There also was a low prevalence of infectious disease in translocated and resident seals, excluding Chlamydophila abortus and enteric bacteria. First-year survival was greater for …

Compulsory Licensing Of Chronic Diseases Pharmaceuticals Thailand, Sakda Thanicul, Matthew Lim Braslow

The Thai Journal of Pharmaceutical Sciences

For pharmaceutical companies, obtaining patent protection for the pharmaceuticals they develop is essential. Patent protection assures that the pharmaceutical company will have a reasonable opportunity to recoup their most likely quite heavy investment in the new drug and allow the company to control the wholesale market price of the drugs. These key intellectual property rights are truly at the heart of the internationally recognized intellectual property regime. For patent right holders in general merchandise, say an innovative paperclip or mousetrap, the absolute right of the patent holder as to the distribution and price is perfectly acceptable. Pharmaceutical patents however, with …

Structural Characterization And Bioactivity Of Cranberry Oligosaccharides, Kimberly M. Auker

Electronic Theses and Dissertations

Complex carbohydrates from plant sources, such as the fruits of cranberry (Vaccinium macrocarpon Aiton), promote human health in a variety of ways. However, complete studies of carbohydrate function often hinge on a detailed understanding and thorough elucidation of the chemical structure. Several methods have been used in the structure elucidation of cranberry oligosaccharides, such as derivatization folloby analysis using gas chromatography-mass spectrometry (GC-MS). In this manner, the identity and quantity of glycosyl units within two cranberry oligosaccharides were investigated through hydrolysis of the oligomers and subsequent synthesis of trimethylsilyl and alditol acetate derivatives. Further analysis using partially methylated alditol acetate …

The Effect Of Masculinity On Post-Deployment Veterans' Help-Seeking Behaviors And Mental Health Outcomes, Nils-Erik Juhani Juanto Laver

Theses and Dissertations

While the current literature has investigated various barriers to reintegration for male veterans of the Armed Forces of the United States, few have investigated how internal processes such as attitudes and beliefs impact reintegration outcomes. Civilian literature has indicated that men who adhere to traditional masculine ideals tend to have a lower quality of life, less help-seeking behaviors, and more mental and physical health problems. This study set out to investigate how traditional masculine values, age, combat exposure, and relative normative male alexithymia may affect mental health, quality of life, and help-seeking behaviors in veterans who were deployed to combat …

Biology

Theodosius Dobzhansky famously proclaimed that “nothing makes sense in biology except in the light of evolution." Though Dobzhansky's statement is sometimes dismissed by biologists in other fields as self-promotion, recent advances in many areas of biology have shown it to be prophetic. For example, genomics, which emerged mostly from molecular biology, is now steeped in evolutionary biology. Evolutionary theory helps to explain our origins, our history, and how we function as organisms and interact with other life forms, all of which are crucial to understanding our future (e.g., [1]–[5]). Evolutionary approaches have helped reconstruct the history of …
