Avian Influenza And The Approach To Designing An H5n1 Vaccine, Lauren N. Hickey May 2027

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. …

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. …

Optimizing Marination Methodology, Holding Temperature, And Holding Time To Upgrade The Physicochemical And Sensorial Attributes Of Japanese Quail (Coturnix Japonica) Breast Fillets, Naveen Uduwawithana, Ruvini Mutucumarana

Turkish Journal of Veterinary & Animal Sciences

The aim was to optimize the effect of meat marination method (unmarinated, tumbling, injection, and immersion), holding temperature (4 oC and 8 oC), and holding time (4 h, 8 h, and 12 h) on the physicochemical and sensorial properties of Japanese quail (Coturnix japonica) breast fillets. Ninety-six deboned breast fillets (mean weight ± SD; 10 g ± 2) from 42-day-old unsexed Japanese quails were marinated. Injection marination showed the highest uptake (p < 0.05). The method × temperature × time interaction (p < 0.05) was significant for cooking yield, meat pH, hardness, cooking loss, and surface color lightness (L*). The highest pH (p < 0.05) was reported when the unmarinated control was retained for 8 h. Tumbling marinated meat when held for 12 h at 8 oC yielded the maximum cooking yield (60.3%). The cooking loss was minimal in unmarinated, tumbled, and immersion-marinated meat when held for 12 h. Irrespective of the temperature, 4-h holding time caused the minimum meat hardness in all four treatments. Tumble-marinated meat when held for 12 h at 8 oC resulted in the minimum cooking loss, hardness, and lightness (L*), as well as the maximum cooking yield. Meat when held at 4 oC for 4 h following injection marination had the highest scores for color, aroma, marinade penetration, flavor, and overall acceptability. In conclusion, quail breast fillets when tumble-marinated and held at 8 oC for 12 h were the best in terms of overall meat quality. Quail breast fillets held for 4 h at 4 oC following injection marination were rated highest by the panelists.

How To Improve Neonatal Beef Calf Health: A Hands-On Workshop Approach, Gabriele Maier, Essam Abdelfattah, Erik Fausak Oct 2026

How To Improve Neonatal Beef Calf Health: A Hands-On Workshop Approach, Gabriele Maier, Essam Abdelfattah, Erik Fausak

Journal of Extension

Even though failure or inadequate transfer of passive immunity in beef calves is common, few interventions on the ranch address the issue. A workshop series that used calf simulators and live calves improved rancher knowledge on passive transfer and other topics relevant to neonatal calf health across operation sizes and experience levels. At the conclusion of the workshop, participants expressed a positive attitude towards using pain control for painful procedures in calves, with cost being the most important reason for not using it. Based on participant feedback, roundtable discussions would improve the workshop format.

The Effect Of Alpha-Lipoic Acid On Sperm Cryobiology And Post-Thaw Quality Of Sperm In Livestock Species, Kashif Ali Malak, Nazar Ali Korejo, Hira Sajjad Talpur, Asmatullah Kaka, Atif Ali Malak, Muhammad Aqeel, Rasool Bux

Journal of Bioresource Management

The cryopreservation of semen is a prerequisite for artificial insemination, germplasm banking and the global distribution of elite livestock breeding. However, spermatozoa are particularly sensitive to cooling and freezing/thawing processes due to the presence of large amounts of polyunsaturated fatty acids in their plasma membranes and limited cytoplasmic antioxidant stores. An increase in reactive oxygen species, lipid peroxidation, mitochondrial dysfunction, acrosomal injury and DNA fragmentation occurs due to stress associated with cryopreservation, which results in the lowering of motility as well as viability and post-thaw low quality of sperm. Alpha-lipoic acid is a natural disulfide compound that acts as a …

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 …

Urinary calculi are commonly encountered in veterinary practice; however, information regarding their distribution of stone that underwent analysis and associated clinical findings remains limited. This study investigated the distribution of urolithiasis and the associations between stone types and clinical and laboratory findings in dogs and cats presented to the Chulalongkorn Small Animal Teaching Hospital between 2020 and 2024. The three most common stone types in both species were calcium oxalate (CaOx), struvite, and urate, with relatively stable trends over the 5-year period. Small-breed dogs had a higher risk of developing CaOx urolithiasis than medium-breed dogs (OR = 10.4, 95% CI …

New Frontiers In Diagnosing Equine Lameness, Hyrum Hoopes, Karl Hoopes Aug 2026

New Frontiers In Diagnosing Equine Lameness, Hyrum Hoopes, Karl Hoopes

All Current Publications

Lameness is one of the most common and expensive health problems seen in horses. Modern technology allows veterinarians to look beneath the surface. Tools such as artificial intelligence (AI), computed tomography (CT), magnetic resonance imaging (MRI), digital radiography (X-rays), nuclear scintigraphy, ultrasound, and positron emission tomography (PET) give clearer, more detailed pictures of what’s happening inside the horse’s leg. Each technology offers different advantages, from identifying uneven movement to revealing hidden damage within bones, joints, or soft tissues. When combined with veterinary visual evaluation, they help pinpoint the cause of lameness faster and more accurately than ever before.

The Thai Journal of Veterinary Medicine

A six-year-old female French Bulldog was referred for neurological diagnostic tests and treatment for progressive paraparesis over an 8-day period. The dog had a history of intervertebral disc extrusion (IVDE) surgical correction two years prior. Neurological examination revealed T3–L3 myelopathy. Magnetic resonance imaging of the thoracolumbar spine confirmed IVDE with spinal cord compression at T13–L1. A minimally invasive percutaneous endoscopic foraminotomy and discectomy (PEFD) was performed to remove the extruded disc material. The patient regained the ability to stand and showed voluntary limb movement 48 hours post-surgery. At the 4-week follow-up, the patient showed a complete recovery to her baseline …

Acemannan/Alginate Composite Hydrogels Promote Sto Cell Spreading And Metabolic Activity, Hong Yongxing, Tharasanit Theerawat Aug 2026

Acemannan/Alginate Composite Hydrogels Promote Sto Cell Spreading And Metabolic Activity, Hong Yongxing, Tharasanit Theerawat

The Thai Journal of Veterinary Medicine

Alginate-based hydrogels are widely used as biocompatible scaffolds. However, their limited cell-adhesive properties restrict their application in tissue engineering. This study aimed to fabricate acemannan/alginate (ACE/ALG) composite hydrogels and evaluate their cytocompatibility and ability to support STO cell spreading and metabolic activity. Composite hydrogels were prepared by blending different concentrations of ACE with alginate, followed by Ca²⁺-mediated ionic crosslinking. Rheological analysis showed that ACE incorporation increased both the storage modulus (G′) and loss modulus (G″) of the hydrogels. Cell viability and morphology were evaluated using Live/Dead staining on day 7, and cellular growth was assessed using an MTT assay on …

The Thai Journal of Veterinary Medicine

Contamination of chicken meat with antimicrobial-resistant bacteria, particularly multidrug-resistant (MDR), colistin-resistant, and extended-spectrum β-lactamase (ESBL)-producing Escherichia coli (E. coli), threatens its safety for human consumption. This study was conducted to determine the prevalence and antimicrobial resistance (AMR) profiles, particularly ESBL production and colistin resistance in E. coli isolated from retail chicken meat in fresh markets in Bangkok, Thailand. A total of 200 (81.6%) E. coli isolates were recovered from 245 chicken meat samples collected from fresh markets across six regions of Bangkok. Among the isolates, 189 (94.5%) exhibited resistance to at least one antimicrobial agent tested, with the …
