Abstract SARS-CoV-2, the causative agent of COVID-19 pandemic, can infect a wide range mammals. Since its spread in humans, secondary host jumps SARS-CoV-2 from humans to multiple domestic and wild populations mammals have been documented. Understanding extent adaptation these animal hosts is critical for assessing threat that spillback animal-adapted into poses. We compare genomic landscapes isolated species profiling mutational biases indicative potentially different selective pressures...

The association of the receptor binding domain (RBD) severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spike protein with human angiotensin-converting enzyme (hACE2) represents first required step for cellular entry. SARS-CoV-2 has continued to evolve emergence several novel variants, and amino acid changes in RBD have been implicated increased fitness potential immune evasion. Reliably predicting effect on ability interact more strongly hACE2 can help assess implications public...

There is mounting evidence of SARS-CoV-2 spillover from humans into many domestic, companion, and wild animal species. Research indicates that have infected white-tailed deer, deer-to-deer transmission has occurred, indicating deer could be a wildlife reservoir source novel variants.

Escherichia coli O157: H7 (EHEC) is a major foodborne pathogen largely transmitted to humans through the consumption of undercooked ground beef. This study investigated efficacy two food-grade, plant-derived antimicrobials, namely rutin (RT), and resveratrol (RV) with or without chitosan (CH) in enhancing EHEC inactivation hamburger patties. Further, effect aforementioned treatments on beef color lipid oxidation was analyzed. Additionally, deleterious effects these antimicrobial determined...

The COVID-19 pandemic has spurred interest in potent and thermostable SARS-CoV-2 vaccines. Here, we assess low-dose immunization with lyophilized nanoparticles decorated recombinant antigens. Spike glycoprotein or its receptor-binding domain (RBD; mouse vaccine dose, 0.1 μg) was displayed on liposomes incorporating a particle-inducing lipid, cobalt porphyrin-phospholipid (dose, 0.4 μg), along monophosphoryl lipid A 0.16 QS-21 μg). Following optimization of lyophilization conditions,...

SARS-CoV-2 continues to evolve and evade vaccine immunity, necessitating vaccines that offer broad protection across variants. Conventional mRNA face cost scalability challenges, prompting the exploration of alternative platforms like trans-amplifying (TA) advantages in safety, manufacturability, antigen dose optimization. Using consensus sequences immunodominant antigens is a promising design strategy for board cross-protection. Combining these two features, we designed evaluated TA...

Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) continues to pose a significant threat public health. Notably, SARS-CoV-2 demonstrates the capacity infect various non-human animal species, including both captive and free-living animals. Earlier experimental studies revealed low susceptibility of domestic cattle (Bos taurus) ancestral B.1 lineage; however, recent findings indicate greater permissiveness Delta variant. While some detected evidence infection in Italy, Germany,...

Multi-drug resistant (MDR) Acinetobacter baumannii is a major nosocomial pathogen causing wide range of clinical conditions with significant mortality rates. A. strains are equipped multitude antibiotic resistance mechanisms, rendering them to most the currently available antibiotics. Thus, there critical need explore novel strategies for controlling in baumannii. This study investigated efficacy two food-grade, plant-derived antimicrobials (PDAs), namely trans-cinnamaldehyde (TC) and...

Abstract Millions of individuals who have recovered from SARS-CoV-2 infection may be eligible to participate in convalescent plasma donor programs, yet the optimal window for donating high neutralizing titer COVID-19 immunotherapy remains unknown. Here we studied response trajectories antibodies directed surface spike glycoprotein and vitro live virus titers (VN) 175 donors longitudinally sampled up 142 days post onset symptoms (DPO). We observed robust IgM, IgG, viral neutralization...

Abstract Many animal species are susceptible to SARS-CoV-2 and could potentially act as reservoirs, yet transmission of the virus in non-human free-living animals has not been documented. White-tailed deer ( Odocoileus virginianus ), predominant cervid North America, infection, experimentally infected fawns can transmit virus. To test hypothesis that may be circulating deer, we tested 283 retropharyngeal lymph node (RPLN) samples collected from 151 132 captive Iowa April 2020 through...
