Zika virus (ZIKV) causes no-to-mild symptoms or severe neurological disorders. To investigate the importance of viral and host genetic variations in determining ZIKV infection outcomes, we created three full-length infectious cDNA clones as bacterial artificial chromosomes for each of three spatiotemporally distinct and genetically divergent ZIKVs: MR-766 (Uganda, 1947), P6-740 (Malaysia, 1966), and PRVABC-59 (Puerto Rico, 2015). Using the three molecularly cloned ZIKVs, together with 13 ZIKV region-specific polyclonal antibodies covering nearly the entire viral protein-coding region, we made three conceptual advances: (i) We created a comprehensive genome-wide portrait of ZIKV gene products and their related species, with several previously ...

This study was designed to compare the efficiency of COWP and CuSO4 at controlling H. contortus populations in goats. A study group of 60 female goats was randomly separated into 3 groups. The does in each group were administered either a copper sulfate drench by weight, a Levamisole drench by weight, or a 4g bolus of COWP. Fecal egg counts and Faffa Malan Charts (FAMACHA), were performed every 2 weeks, and Packed Cell ...


Can Prescribed Fire Reduce Tick Parasitism Of Birds?, Leslie A. Sterling, Kim Medley, Katie Westby, Solný Adalsteinsson 2018 Washington University in St Louis

Can Prescribed Fire Reduce Tick Parasitism Of Birds?, Leslie A. Sterling, Kim Medley, Katie Westby, Solný Adalsteinsson

Undergraduate Research Symposium Posters

Tick-borne diseases spread through enzootic transmission cycles that often involve ticks parasitizing bird hosts. Some avian species are competent reservoirs, amplifying the pathogens that cause tick-borne illnesses in humans. Prescribed burns in forests have the potential to reduce tick-borne disease risk if they limit interactions between ticks and infectious wildlife hosts. Although prescribed burns are increasingly being used for a variety of habitat management purposes, little is known about how they affect tick-host interactions. We hypothesize that if prescribed fires reduce tick abundance, then birds in burned forest plots will host fewer ticks than birds in unburned forest plots. Experimental ...


Antibiotic Residues In Milk From Three Popular Kenyan Milk Vending Machines, Amos Kosgey, Anakalo Shitandi, Jason W. Marion 2018 Eastern Kentucky University

Antibiotic Residues In Milk From Three Popular Kenyan Milk Vending Machines, Amos Kosgey, Anakalo Shitandi, Jason W. Marion

EKU Faculty and Staff Scholarship

Milk vending machines (MVMs) are growing in popularity in Kenya and worldwide. Milk vending machines dispense varying quantities of locally sourced, pasteurized milk. The Kenya Dairy Board has a regulatory framework, but surveillance is weak because of several factors. Milk vending machines’ milk is not routinely screened for antibiotics, thereby increasing potential for antibiotic misuse. To investigate, a total of 80 milk samples from four commercial providers (N = 25), street vendors (N = 21), and three MVMs (N = 34) were collected and screened in Eldoret, Kenya. Antibiotic residue surveillance occurred during December 2016 and January 2017 using Idexx SNAP tests for ...

Protocol For A Scoping Review Of Influenza A Viruses Infecting Swine Or Directly Related To Swine, Sheila Keay, Zvonimir Poljak, Annette O'Connor, Robert Friendship, Terri O'Sullivan, Jan Sargeant

Veterinary Diagnostic and Production Animal Medicine Reports

Influenza A viruses are endemic in swine populations, a global zoonotic concern, and associated with economically significant disease in food animal production. Global partnerships (Star-IDAZ 2014, USDA 2014, European Food Safety Authority 2015, WHO 2017) have conducted gap analyses on Animal Influenza Research and set research agendas for various species. To date, however, an explicit inventory of the broad areas of accumulated research on Influenza A viruses in swine or directly related to swine (IAV-S), constructed in compliance with syntheses standards for literature mapping (Arksey and O’Malley 2005), is not available.

In particular, a baseline descriptive categorization of the ...

A Protocol For A Systematic Review And Meta-Analysis Of Efficacy Of Infectious Bovine Keratoconjunctivitis And Assessment Of Comprehensiveness Of Reporting, Olivia Weaver, Ella Meyer, Binh Doan, Jan Sargeant, Annette M. O'Connor

Veterinary Diagnostic and Production Animal Medicine Reports

Infectious bovine keratoconjunctivitis, commonly known as pinkeye, limits production and weight gain in pre-weaned calves, resulting in significant economic loss each year. IBK is one of the most common diseases in pre-weaned calves which leads to clinical signs from mild conjunctivitis to severe ulceration, corneal perforation, and blindness [4]. Due to large economic losses and limits in production and weaning weight, use of effective vaccines to prevent IBK is imperative.

Moraxella bovis is the primary causal organism of IBK [4, 5]. However, available evidence does not suggest that vaccination is effective for preventing naturally occurring IBK. Although individual studies and ...

Veterinary Diagnostic and Production Animal Medicine Reports

The treatment and prevention of infectious diseases in pigs is an important aspect of swine production worldwide. The prudent use of antimicrobials and other therapeutic drugs is a primary responsibility of swine producers and veterinarians and decisions surrounding the use of drug therapy include considerations such as cost, efficacy, and food safety. The World Health Organization has published numerous reports urging all stakeholders concerned with both food-producing animals and humans to establish recommended steps to enhance the prudent use of antimicrobials (WHO, 2015). Similarly, the Organization for Animal Health has also published recommendations and position statements regarding prudent use and ...


Comparative Analysis Of Low Molecular Weight Fraction Of Conditioned Media Derived From Starvation-Dormant And Anaerobically-Dormant Mycobacterium Avium Subsp. Paratuberculosis, Marina Buciuc 2018 Minnesota State University, Mankato

Comparative Analysis Of Low Molecular Weight Fraction Of Conditioned Media Derived From Starvation-Dormant And Anaerobically-Dormant Mycobacterium Avium Subsp. Paratuberculosis, Marina Buciuc

All Theses, Dissertations, and Other Capstone Projects

Johne's disease (JD) caused by Mycobacterium avium subsp. paratuberculosis (MAP) is a contagious chronic enteritis affecting all ruminants and causing economic loss of at least $250 million annually in the US dairy industry. One of the major limitations in the diagnosis of JD is the low sensitivity of fecal culture in animals with no clinical signs of the disease, but who are actively shedding MAP. Persistence of MAP in the host with no apparent signs of infection is attributed to its ability to enter a dormant state wherein the bacterium is viable, but is not able to replicate until ...


Universal Swine Influenza Antigen And Vaccine, Zhao Wang 2018 South Dakota State University

Universal Swine Influenza Antigen And Vaccine, Zhao Wang

Electronic Theses and Dissertations

Swine influenza A viruses pose a serious concern for global health and worldwide swine industry considering their evasion from vaccine-induced immune responses. Formulation of effective influenza vaccines can be complicated by both antigenic shift to a different subtype of hemagglutinin (HAs) and antigenic drift within a particular HA subtype. To address these concerns, we employed a systematic approach to determine the antigenic determinants of swine influenza A viruses by focusing on H1 and H3 subtypes. In parallel, we used a cross-disciplinary approach including structural biology and modeling, virology, and immunology to identify swine influenza A virus-derived HA fusion intermediates broadly ...

Histomonas Elisa, Jessica L Martinez 2017 University of Tennessee, Knoxville

Histomonas Elisa, Jessica L Martinez

EURēCA: Exhibition of Undergraduate Research and Creative Achievement

Histomonas meleagridis is a protozoan parasite of avians and is the causative agent in Histomonosis, commonly known as Blackhead Disease. Current methods for diagnosing the presence of H. meleagridis are limited to parasite culture or Polymerase Chain Reaction (PCR) to amplify target DNA. This project aims to develop an enzyme-linked immunosorbent assay (ELISA) for faster and more sensitive diagnosis of Histomonas infections. Cultures of H. meleagridis parasites were purified, and surface antigens were extracted using a spectrum of chemical solutions. The various antigen solutions were subjected to an ELISA, with serum from birds immunized for H. meleagridis as positive controls ...


Cross-Reactive Immunity To Porcine Reproductive And Respiratory Syndrome Virus And Its Contribution To Protection, Ignacio Correas 2017 University of Nebraska - Lincoln

Cross-Reactive Immunity To Porcine Reproductive And Respiratory Syndrome Virus And Its Contribution To Protection, Ignacio Correas

Dissertations & Theses in Veterinary and Biomedical Science

Due to the vast geographical distribution and significant economic losses generated, porcine reproductive and respiratory syndrome virus (PRRSV) can be considered the most important swine pathogen of contemporary times. Current control and eradication strategies against PRRSV have difficulty succeeding because of their complex nature and the absence of an effective vaccine. A major obstacle for PRRSV vaccine development is the broad heterogeneity of the virus, both at the genetic and antigenic level, its rapid evolution, and an incomplete knowledge of the immune responses responsible for clearing the virus from the host. Specifically, how known correlates of protection against PRRSV—neutralizing ...


Developing A Plant Virus-Based Expression System For The Expression Of Vaccines Against Porcine Reproductive And Respiratory Syndrome Virus, Hong Hanh Tran 2017 The University of Western Ontario

Developing A Plant Virus-Based Expression System For The Expression Of Vaccines Against Porcine Reproductive And Respiratory Syndrome Virus, Hong Hanh Tran

Electronic Thesis and Dissertation Repository

Virus-based expression systems have been widely exploited for the production of recombinant proteins in plants during the last three decades. Advances in technology have boosted scale-up manufacturing of plant-made pharmaceuticals to high levels, via the complementation of transient expression and viral vectors. This combination allows proteins of interest to be produced in plants within a matter of days and thus, is well suited for the development of plant-made vaccines or therapeutics against emerging infectious diseases and potential bioterrorism agents. Several plant-based products are currently in varying stages of clinical development. To investigate the viability of virus-based expression systems for plant-made ...

Bovine tuberculosis is a zoonotic disease of global public health concern. Development of diagnostic tools to improve test accuracy and efficiency in domestic livestock and enable surveillance of wildlife reservoirs would improve disease management and eradication efforts. Use of volatile organic compound analysis in breath and fecal samples is being developed and optimized as a means to detect disease in humans and animals. In this study we demonstrate that VOCs present in fecal samples can be used to discriminate between non-vaccinated and BCG-vaccinated cattle prior to and after Mycobacterium bovis challenge.

Equine arteritis virus (EAV) has a global impact on the equine industry as the causative agent of equine viral arteritis (EVA), a respiratory, systemic, and reproductive disease of equids. A distinctive feature of EAV infection is that it establishes long-term persistent infection in 10 to 70% of infected stallions (carriers). In these stallions, EAV is detectable only in the reproductive tract, and viral persistence occurs despite the presence of high serum neutralizing antibody titers. Carrier stallions constitute the natural reservoir of the virus as they continuously shed EAV in their semen. Although the accessory sex glands have been implicated as ...

Infection Of Commercial Laying Hens With Newcastle Disease Virus: Differing Responses Between Birds Provide Potential For Genetic Improvement Through Selection, Kaylee Rowland, Huaijun Zhou, Rodrigo Gallardo, David Bunn, Susan J. Lamont

Susan J. Lamont

Exotic Newcastle Disease Virus (ENDV) cause extremely rapid mortality in chickens after exposure to the virus. People rely heavily on poultry to provide protein and income in many places where NDV is not effectively controlled through vaccination and biosecurity. Losses from NDV contribute to worldwide hunger and poverty. It may be possible to use genetic selection to produce chickens that have a stronger immune response in the face of NDV challenge. For genetic selection to be successful, two major elements are required: differences in immune response among chickens and genetic control of these differences. This study clearly demonstrated the existence ...
