Ayanna Glaize is a Ph. D. candidate working in Dr. Sid Thakur’s lab in the Department of Population Health and Pathobiology at North Carolina State University. Her current research is focused on antimicrobial-resistant surveillance of foodborne pathogens and developing tools that can reduce food safety risks. She is interested in extending her research of antimicrobial-resistant pathogens while expanding her scope to include metagenomics. Ayanna is also interested in becoming involved with public health research and studying neglected tropical diseases.

Tracking the Transmission of Antimicrobial-Resistant Non-O157 Escherichia coli and Salmonella Isolates at the Interface of Food Animals and Fresh Produce from Agriculture Operations Using Whole-Genome Sequencing

Glaize, A., Hull, D., Raymond, L., Vliet, A. H. M., Gutierrez-Rodriguez, E., & Thakur, S. (2022, August 4). FOODBORNE PATHOGENS AND DISEASE, Vol. 8.

By: A. Glaize n, D. Hull n, L. Raymond n, A. Vliet*, E. Gutierrez-Rodriguez* & S. Thakur n

author keywords: extended-spectrum beta-lactamase; phylogroups; antimicrobial resistance; enteropathogenic Escherichia coli; dairy; poultry
MeSH headings : Agriculture; Animals; Anti-Bacterial Agents / pharmacology; Anti-Bacterial Agents / therapeutic use; Drug Resistance, Bacterial / genetics; Escherichia coli; Escherichia coli Infections / veterinary; Microbial Sensitivity Tests; Poultry; Salmonella; Whole Genome Sequencing
TL;DR: This study demonstrates the prevalence of AMR and virulence genes on small-scale sustainable farms and highlights the advantage of using WGS to assess the impact of the VBZ to reduce the transmission of E. coli and Salmonella. (via Semantic Scholar)

2021 journal article

The effect of vegetation barriers at reducing the transmission of Salmonella and Escherichia coli from animal operations to fresh produce


By: A. Glaize n, M. Young n, L. Harden n, E. Gutierrez-Rodriguez* & S. Thakur n

author keywords: Seasonality; Repetitive PCR; Dairy; Poultry; Distance; Wind
MeSH headings : Animals; Cattle; Dairying; Escherichia coli / growth & development; Escherichia coli / isolation & purification; Escherichia coli Infections / transmission; Escherichia coli Infections / veterinary; Farms; Feces / microbiology; Lettuce / microbiology; Solanum lycopersicum / microbiology; Poultry / microbiology; Salmonella / growth & development; Salmonella / isolation & purification; Salmonella Infections, Animal / transmission
TL;DR: Data analysis suggests that the VB is an effective tool at reducing the transmission of E. coli and Salmonella from animal farms to fresh produce fields, and recommends the need for more effective bioremediation and prevention control measures to use in conjunction with VBs to reduce pathogen transmission.

Transmission of antimicrobial resistant non-O157 Escherichia coli at the interface of animal-fresh produce in sustainable farming environments

International Journal of Food Microbiology, 319, 108472.

By: A. Glaize n, E. Gutierrez-Rodriguez n, I. Hanning*, S. Díaz-Sánchez*, C. Gunter n, A. van Vliet*, W. Watson n, S. Thakur n

author keywords: Pathogen transmission; Sustainable production systems; Antimicrobial resistance; Phylotyping; Non-O157 E. coli
MeSH headings : Ampicillin / pharmacology; Animals; Anti-Bacterial Agents / pharmacology; Enterotoxigenic Escherichia coli / drug effects; Enterotoxigenic Escherichia coli / genetics; Enterotoxigenic Escherichia coli / isolation & purification; Escherichia coli Infections / microbiology; Escherichia coli Infections / transmission; Farms; Foodborne Diseases / microbiology; Genome, Bacterial / genetics; Manure / microbiology; Microbial Sensitivity Tests; Serogroup; Streptomycin / pharmacology; Sulfisoxazole / pharmacology; Vegetables / microbiology
TL;DR: The results of this study show the potential of AMR E. coli transmission between animal feeding operations and fresh produce, and more studies are recommended to study this interaction and prevent dissemination in sustainable farming systems. (via Semantic Scholar)

2018 journal article

Effect of Marek’s disease vaccines on interferon and toll like receptors when administered in ovo

Veterinary Immunology and Immunopathology, 201, 62–66.

By: I. Gimeno*, A. Glaize* & A. Cortes

author keywords: IFN; TLR; in ovo; Vaccines; Marek's disease; Chickens
MeSH headings : Animals; Chick Embryo; Chickens / immunology; Herpesvirus 2, Gallid; Interferon-gamma / genetics; Interferon-gamma / immunology; Interferons / genetics; Interferons / immunology; Marek Disease / immunology; Marek Disease / prevention & control; Marek Disease Vaccines / administration & dosage; Marek Disease Vaccines / immunology; Specific Pathogen-Free Organisms; Spleen / immunology; Toll-Like Receptor 3 / genetics; Toll-Like Receptor 3 / immunology; Toll-Like Receptors / genetics; Toll-Like Receptors / immunology; Vaccination / veterinary
TL;DR: It is shown that intra-amniotic vaccination at ED18 with HVT but not with CVI988 rendered chickens more immunocompetent at hatch and the role of increased transcription of TLR-3 and IFN-γ in such positive effect warrant further investigations. (via Semantic Scholar)
