Research molecular biologist Dana Nayduch of the Agricultural Research Service, U. S. Department of Agriculture (USDA-ARS), will speak on "Can Surveying Microbial Communities of House Flies Help Us Understand Emerging Threats to Animal and Human Health?" at 4:10 p.m., Wednesday, March 1 in 122 Briggs Hall, Kleiber Hall Drive, UC Davis campus.
Her lecture also will be virtual. The Zoom link:

Nayduch, based in Manhattan, Kansas, will be introduced by her colleague, medical entomologist-geneticist Geoffrey Attardo, assistant professor, UC Davis Department of Entomology and Nematology.
"Dana is doing very cool work with house flies and looking at how bacteria in the fly are trading antibiotic resistance genes among themselves," said Attardo. "It's an interesting and scary system as antibiotic resistance is so high due to antibiotic usage in livestock rearing."
"House flies (Musca domestica L.) are ubiquitous, cosmopolitan pests inhabiting urban, rural and agricultural environments throughout the world. In these habitats acquire microbes from septic substrates that are used for feeding and reproduction, Nayduch says in her abstract. "Flies subsequently harbor and disseminate these microorganisms which may pose a risk to human and animal health. Our research characterizes and analyzes microbial communities of house flies using culture-based and molecular approaches in order to better understand their roles in the transmission of important bacterial disease agents and/or antimicrobial resistance. Because the microbial communities within house flies represent a snapshot of the microbes found in their local habitat, we also gain valuable insight into existing and emerging microbial threats to humanand animal health through our surveys which can help in predicting and preventing disease."
A pre-seminar coffee will take place from 3:30 to 4:10 in 158 Briggs.
Dana received her bachelor's degree in animal science from Rutgers University and her doctorate in zoology from Clemson University, where she studied house flies as vectors for pathogens. She served as a postdoctoral fellow at Yale University School of Public Health, working on molecular-genetic studies of tsetse flies. She then joined Georgia Southern University (GSU) as an assistant professor of biology in 2004, advancing to associate professor in 2009. At GSU she received NIH-R15 funding to study house fly-microbe molecular interactions.
Active in the Entomological Society of America (ESA), Nayduch is the vice president-elect of the Medical, Urban and Veterinary Entomology (MUVE) Section. A peer reviewer for the Journal of Medical Entomology and an editorial board member and subject editor for Annals for ESA, she organized and edited the first special collection for Annals: “Filth Fly-Microbe Interactions."
The UC Davis Department of Entomology and Nematology's winter seminars are held on Wednesdays at 4:10 p.m. in 122 Briggs Hall. All are virtual. Urban landscape entomologist Emily Meineke, assistant professor, coordinates the seminars. (See schedule.) She may be reached at ekmeineke@ucdavis.edu for technical issues.
