Research InterestsFish Diseases, Parasitology, Pathogens of Zebra Fish

Courses Taught:  MB 480/580 General Microbiology; BHS 329 Mechanisms of Disease;  VMB 760 Veterinary Parasitology; Health and Colony Management of Laboratory Fish, An annual summer course at the Center for Science Entrepreneurship in Bar Harbor, Maine,  MDI Biological Laboratory.


Presently the Kent lab is focusing on two major research areas; diseases of zebrafish in research facilities and impacts of pathogens on wild fishes in Oregon. In both areas, we are focusing on the study of chronic infectious diseases. In the past decade there has been a dramatic increase in the use of zebrafish as a model in biomedical research. Underlying chronic diseases are of concern as they relate to non-protocol induced variation in laboratory fish, as they would with any laboratory animal.  Microsporidosis (caused by Pseudoloma neurophilia); mycobacteriosis (caused by various species of Mycobacterium); the nematode Pseudocapillaria tomentosa, and Mycoplasma-related intestinal cancers are all common in zebrafish facilities, and are under investigation at this time. This work is supported by NIH Office of Research Infrastructure Programs (NIH ORIP), National Institute of Allergy and Infectious Diseases (NIH NIAID), and the National Cancer Institute (NIH NCI).  Co-investigators for this research at OSU include Dr. Thomas Sharpton (Departments of Microbiology and Statistics), Dr. Justin Sanders (Department of Biomedical Sciences), and Dr. Karen Guillemin (University of Oregon).  Dr. Kent is also a Co-PI at the Zebrafish International Resource Center at the University of Oregon where he assists with health studies and their diagnostic service.  esDr. Kent was instrumental in the design of an on-line manual on zebrafish diseases for the research community and he and Dr. Robert Tanguay established the SPF (Specific Pathogen Free) zebrafish research colony at the Sinnhuber Aquatic Resource Center (OSU).  This was supported by the NIEHS Environmental Health Sciences Center and NIH ORIP.  

Wild Fishes in Oregon: for the last several years we have been investigating the role of multiple pathogen infections with prespawning Chinook salmon from the Willamette River in collaboration with Dr. Carl Schreck and Dr. James Peterson (Dept. of Fisheries and Wildlife, OSU; and USGS) and Dr. Justin Sanders through the support of the U.S. Army Corps of Engineers.  The Kent lab has also recently completed a study on the impacts of parasites on endangered sucker species in the Klamath Lake in collaboration with Dr. Doug Markle (Dept. of Fish and Wildlife, OSU) and Dr. James Peterson.  This research is funded by the U.S. Bureau of Reclamation.

Dr. Kent also investigates other parasites, including those infecting terrestrial animals, and is exploring the taxonomic variability of Neorickettsia spp. associated with salmon poisoning, a common and deadly disease of dogs in Oregon.  This work is in collaboration with Dr. Sanders and Dr. Vasyl Tkach (University of North Dakota).


With appointments in the College of Science, College of Agriculture, and the Carlson College of Veterinary Medicine, Dr. Kent received both the OSU Alumni Association Distinguished Professor Award and the Agricultural Research Foundation Distinguished Faculty Award for his superior academic performance, professional renown and service to the University and to the Public.  He also received the 2018 Outstanding Steward of Zebrafish Husbandry from the Zebrafish Husbandry Association (International Society) for his research with zebrafish.
