Nayduch, based in Manhattan, Kansas, will speak at 4:10 p.m., Wednesday, March 1 in 122 Briggs Hall. Her lecture also will be virtual. The Zoom link:
"Dana is doing very cool work with house flies and looking at how bacteria in the fly are trading antibiotic resistance genes amongst themselves," said the seminar host, medical entomologist-geneticist Geoffrey Attardo, assistant professor, UC Davis Department of Entomology and Nematology. "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. Flies subsequently harbor and disseminate these microorganisms which may pose a risk to human and animal health," Nayduch says in her abstract. "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 will take place from 3:30 to 4:10 in 158 Briggs.
Nayduch, an authority on fly-microbe interactions, joined USDA in August of 2011. She is a member of the USDA-ARS Arthropod-Borne Animal Diseases Research Unit, researching molecular and microbiological studies of Culicoides midges and house flies. She works with several laboratories on comparative transcriptomic and microbiomic studies of Muscid flies.
Nayduch 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.
Nayduch, active in the Entomological Society of America (ESA), 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. A pre-seminar coffee is held from 3:30 to 4:10 p.m. in 158 Briggs. Urban landscape entomologist Emily Meineke, assistant professor, coordinates the seminars. (See schedule.)
