More than 60 percent of all human infectious diseases originate in animals, and within the past century, an unprecedented number of diseases have emerged that pose significant risks to wild

and domestic animal and human populations. Many of them originate in wild birds. Jen Owen, an associate professor in the Michigan State University (MSU) Department of Fisheries and Wildlife, is working on a project funded by the National Science Foundation (NSF) to assess variation in the pathogen load in virus-infected birds.

It is an NSF Career grant, one of the most prestigious awards given to early-career faculty members. Unlike many others, these grants require both a research and a teaching component and an integration of the two. Through the project, Owen is looking to better understand why some individuals within a population carry higher pathogen loads than others. She is particularly interested in “supershedders,” the ones in a population that, for unknown reasons, are responsible for most of the pathogen load.

“We’re looking to see if there is a genetic basis for supershedders by using transcriptomics and RNA sequencing,” she said. “We want to see if there are genes that are differently expressed in supershedders than in non-supershedders.”

Owen said there is a significant knowledge gap in disease epidemiology when it comes to understanding the intrinsic and extrinsic factors that determine variation in infectiousness. Knowingmore about the basis for pathogen load variation and why some individuals shed much larger amounts will provide information to develop more realistic epidemiological models that lead to cost-effective, targeted prevention and control strategies, she said.
