Avian Influenza And The Approach To Designing An H5n1 Vaccine, Lauren N. Hickey
Avian Influenza And The Approach To Designing An H5n1 Vaccine, Lauren N. Hickey
Honors Program: Senior Projects (Public)
The Avian influenza virus (AIV) H5N1 has been responsible for the culling and deaths of millions of birds since 2022 with concern for wildlife, livestock, and human infections occurring as well. With eggs flying off the shelves in grocery stores, even individuals not involved in the agricultural industry have seen the drastic effects of this disease first-hand. For chickens, this virus works quickly and overpowers the innate immune system before the adaptive immune system has time to properly respond. Therefore, a safe and effective vaccine could reduce the number of poultry deaths and prevent the continuous spread of the infection. …

Genetic Diversity And Morphotypes Of Haemonchus Contortus In Sheep In Thailand: A Combined Morphological And Molecular Approach, Gunjan Das, Mohamed H. Hamad, Witchuta Junsiri, Piyanan Taweethavonsawat
The Thai Journal of Veterinary Medicine
Haemonchus contortus is a highly pathogenic gastrointestinal nematode of small ruminants, yet molecular information on sheep-derived isolates in Thailand remains limited. This study aimed to characterize H. contortus recovered from sheep in Nakhon Pathom Province using integrated morphological and molecular approaches. Adult nematodes collected post-mortem from the abomasum were examined morphologically, and the internal transcribed spacer 2 (ITS2) region of ribosomal DNA was amplified and sequenced. Morphological examination identified males with characteristic copulatory bursae and females exhibiting linguiform, knobbed, and simple vulvar morphotypes. ITS2 sequences showed 95.26–98.11% identity with reference H. contortus sequences deposited in GenBank. Molecular and phylogenetic analyses …

The timing of biological events for wildlife species reflects and influences ecological and evolutionary processes and helps guide management actions to meet conservation objectives. Climate change may cause phenological shifts across trophic levels and ecosystems, which can have broad ecological impacts. Shifts may also result in mistiming between management practices based on historical conditions and current biological events, reducing the effectiveness of natural resource management and conservation efforts. We analyzed nesting phenology patterns over recent decades across North America for 44 species of grassland-nesting birds, including waterfowl, upland gamebirds, shorebirds, and passerines, many of which have experienced precipitous population declines. …

Double-crested cormorants (Nannopterum auritum) are piscivorous, migratory waterbirds that often conflict with fisheries interests in North America, stemming from depredation effects on fish populations. A new permitting process in the United States allows natural resource agencies to request permits for lethal take of cormorants in special instances like depredation of managed fish stocks. This rule does not include guidance for when cormorant take might be actionable. We developed a hierarchical structured decision making (SDM) framework for evaluating whether, when, and how much cormorant take might be necessary. A broad-scale, or “umbrella,” SDM framework established the overarching problem, objectives …

The Impact Of A Nf-Κb Signaling Inhibitor On The Antibacterial Activity Immune Response In The Cat Flea (Ctenocephalides Felis), Caroline M. Singer
The Impact Of A Nf-Κb Signaling Inhibitor On The Antibacterial Activity Immune Response In The Cat Flea (Ctenocephalides Felis), Caroline M. Singer
College of Graduate Studies: Theses & Dissertations
Ctenocephalides felis are vectors of several bacterial pathogens that cause disease in humans and animals, including Bartonella henselae and Rickettsia felis. Successful pathogen transmission requires that microbes survive the immune defenses of the flea digestive tract following blood feeding. In insects, humoral immune responses are regulated primarily by the Toll and immune deficiency (IMD) signaling pathways, with the IMD pathway serving as the principal defense against Gram-negative bacteria. Although genomic and transcriptional evidence indicate that cat fleas encode and express components of the IMD signaling pathway, the functional roles of individual pathway components within the flea digestive tract remain …
Surveillance Of A Novel Vesivirus Discovered In An Urban Mephitis Mephitis Population, Amanda E. Diggins
Surveillance Of A Novel Vesivirus Discovered In An Urban Mephitis Mephitis Population, Amanda E. Diggins
Honors Theses and Capstones
Caliciviridae is a family of non-enveloped, positive-sense, single stranded RNA viruses, including eleven defined genera that contain important pathogens of humans and animals. Within the Caliciviridae family, the genus Vesiviridae includes feline calicivirus, a leading cause of upper respiratory disease in cats, and vesicular exanthema of swine virus, a historical disease of domestic swine that has now been implicated in several marine mammal vesicular diseases, one of which has been confirmed zoonotic. Urban landscapes create a unique environment for rapid intra- and interspecies transmission of viruses. Clustered resources attract high-density populations of synanthropic wildlife species, increasing spatial overlap and heightening …

The giant panda (Ailuropoda melanoleuca) is a world-recognized rare wildlife endemic to China. Oral microorganisms may cause dental and other systemic diseases. Additionally, antibiotic resistance in this cute mammal may spread widely to travelers. In this mini review, we illustrated the oral core microorganisms of the giant pandas and their characteristics, as well as their prevalence of antibiotic resistance genes. Although there is limited availability in panda sample collection, researchers have made great efforts to find the characteristics of the giant pandas’ oral microbiota, including Enterococcus faecium, Enterococcus faecalis, and Staphylococci, with antibiotic resistance genes optrA …
Recovery And Characterization Of Moraxella Species From Bovine Specimens, Laura G. Leger
Recovery And Characterization Of Moraxella Species From Bovine Specimens, Laura G. Leger
School of Veterinary and Biomedical Sciences: Dissertations, Theses, and Student Research
The family Moraxellaceae is made up of a diverse group of 24 named species that fall into three phylogenetic groups. While most Moraxella spp. act as commensal respiratory and/or ocular flora of mammals, some are associated with disease. One of these diseases, infectious bovine keratoconjunctivitis (IBK), has significant welfare and economic impacts to both cattle and cattle producers. Moraxella bovis is the only experimentally determined cause of IBK, however, an association of Moraxella bovoculi with disease has been proposed. Currently, available vaccines do not have high levels of efficacy in the field. Culture based methods are the gold standard for …

nfluenza A viruses (IAVs) can infect birds and various mammals. In this study, we retrospectively isolated and characterized IAVs (n=8) from oropharyngeal and cloacal swab samples of free-grazing ducks collected during December 2018 to December 2021, by using egg inoculation and whole-genome sequencing. The IAVs could be subtyped as IAV-H4N2 (n = 3) and IAV-H4N8 (n = 5) using real-time RT-PCR assays. Genetic and phylogenetic analyses revealed that all eight genes of Thai IAV-H4 belong to the Avian Eurasian lineage. Both Thai IAV-H4N2 and IAV-H4N8 exhibited low pathogenic avian influenza (LPAI) characteristics and were susceptible to oseltamivir and amantadine. This …
Overcoming Vaccine-Associated Enhanced Respiratory Disease In Swine Flu With Lipid Nanoparticle-Dna Technology, The Nguyen
School of Veterinary and Biomedical Sciences: Dissertations, Theses, and Student Research
The two primary challenges in developing vaccines against swine influenza A virus (IAV-S) are the continuous viral evolution and vaccine-associated enhanced respiratory disease (VAERD). Current vaccine strategies share a common limitation: the significant time required for licensing updated vaccines. Moreover, the strain selection for vaccine updates depends entirely on predictions, raising the risk that chosen strains may not match circulating viruses. Such mismatches not only reduce vaccine efficacy but also risk exacerbating disease severity through VAERD. Here, in this thesis, we developed and evaluated a novel DNA-based vaccine platform designed to address the need for rapid updates in response to …

Karbala International Journal of Modern Science
The viral disease affects the whiteleg shrimp (Litopenaeus vannamei) and causes losses. Immunostimulants are recognized as a more environmentally friendly approach to disease management and antimicrobial properties of aquatic organisms. Watercress (Nasturtium officinale) is an aquatic plant species that contains antioxidant properties that can protect the organism from disease and boost the immune system. Shrimp rely heavily on innate immunity to combat infectious agents due to their absence of adaptive immunity. Peroxinectin and scavenger receptor class B (SRB) play essential roles in the shrimp defense system. This research employs a bioinformatic to assess the immunostimulatory potential …

The Thai Journal of Veterinary Medicine
Protective antibody against classical swine fever virus (CSFV) is an important parameter used for disease monitoring in CSFV-endemic areas. Enzyme-linked immunosorbent assay (ELISA) is a simple and practical serological assay for CSFV antibody detection. However, the use of CSFV ELISAs in CSFV antibody-positive herds, i.e., CSFVvaccinated or -previously infected herds, was limited by an application of the test results. This study aimed to evaluate the correlation and estimation of protective antibody levels detected by ELISA and serum neutralization assay. A total of 522 negative and positive serums were tested by SN and ELISA in parallel. Comparisons of sample-to-positive (S/P) values …

One major limitation to the study of equine disease is the lack of in vitro models that accurately reflect the dynamic physiology of the horse. Thus, there is a pressing need to develop in vitro systems that recapitulate diverse equine tissue and organ microenvironments. To overcome this deficiency, we developed multiple biomimetic equine organoid systems that can be employed for a variety of investigations aimed at resolving outstanding questions in infectious disease pathogenesis, therapeutic development and drug metabolism, host defense mechanisms, immune-modulated disease, and equine developmental biology. Our innovative platform incorporates novel equine intestinal enteroid and airway organoid models derived …

Astronauts on the proposed Mars missions will be exposed to extended periods of social isolation (SI) and space radiation (SR). SI and SR-induced immune dysregulation can result in persistent neuroinflammation and neuronal damage which could negatively impact an astronaut’s health and ability to maintain adequate levels of performance. The synergistic effects of combined SI and SR on immune system functionality and the brain remain unknown. Determining how single and combined inflight stressors modulate the immune system is crucial for fully understanding pathways impacting astronaut health and performance. We used ground-based analogs of SI and SR in rodent models to investigate …

The Relationship Between Periodontal Disease Of Feline And Oral Core Microbiome, Ziyao Zhou
The Thai Journal of Veterinary Medicine
The microbiome of the oral cavity is complex with the average adult harboring about 50 to 100 billion bacteria which represent about 200 predominant bacterial species. There are a large number of microbes in the oral cavity of the feline, normally beneficial to oral health and safety maintenance. However, when the balance of bacteria lost, it may occur feline stomatitis and periodontitis, which seriously endanger local oral health. Environmental implication, feeding model, age and genetic factors may be main factors affecting oral composition of microbiome. Filifactor alocis, Porphyromonas gingivals, Tannerella forsythia and their interactions are main pathogen that …

Broiler chickens have been suggested as an important source of antibiotic resistance Escherichia coli (E. coli) and Klebsiella pneumoniae (K. pneumoniae). The coinfection of multiple species of bacteria provides a specific ecological niche for the plasmid-mediated exchange of antibiotic-resistance genes. However, there is limited information about antimicrobial resistance (AMR) phenotypes of E. coli and K. pneumoniae isolates from broiler chickens. This study aimed to isolate E. coli and K. pneumoniae from broiler chicken farms in Thailand by observing the antibiotic resistance profiles and detecting the coexistence of these two bacteria. A total of 26 E. coli and 29 …

Government agencies and landowners use a variety of lethal methods to reduce invasive wild pig populations and resulting agricultural damages. To provide decision-makers with information regarding Alabama farmers’ experiences with wild pigs and their preferences for management actions, we surveyed Alabama Farmers Federation members in 2020. We found that wild pigs were commonly present on livestock, timber, and crop production acreage, but wild pig damages and costs were much more common among crop producers. Respondents' wildlife acceptance capacity for wild pigs was low and all lethal control methods were considered aceptable by most reposndents, particularly those performed by landowners. While …
