A mechanism that prevents self-sensing
Congratulations to Dr. Martin Schuster and graduate student Parker Smith whose article: Antiactivators prevent self-sensing in Pseudomonas aeruginosa quorum sensing., Proc. of the National Academy of Sciences of the USA, 2022 (DOI: 10.3410/f.742191979.793593760), has been recommended in Faculty Opinions as being of special significance in its field by Faculty Member Andrew Goryachev.
Dr. Jerri Bartholomew and Dr. Stephen Atkinson have been awarded a grant from the Binational Agriculture Research and Development Fund in partnership with Dr. Tamar Lotan at the U. of Haifa, Israel to study how fish parasites sense and sting their fish hosts: using salmon and trout models in the USA and farmed tilapia in Israel. The objective is to characterize host sensing and signaling mechanisms in the hopes of preventing infection.
Drs. Theo Dreher and Ryan Mueller have identified the precise forms of toxin producing cyanobacteria from Detroit Lake, the source of drinking water for Salem, Oregon. Dreher said knowing which organisms to study will be key to learning how to prevent harmful algal blooms in the future. Once you identify the harmful organism you can study it in isolation and look at the factors that lead to its massive growth in a bloom, Dreher said. The study found two types[...]
Dr. Martin Schuster and graduate student Parker Smith have identified a mechanism that allows bacteria to wait for collective communication within groups of cells, preventing signal “short-circuiting” by individual cells. Bacterial communication relies on chemical signaling molecules that regulate gene expression in a process known as quorum sensing. Quorum sensing coordinates many different collective behaviors in bacterial populations such as infection, biofilm formation, microbial warfare, and nutrient acquisition.

Congratulations to former micro student Brandon Kieft and Dr. Ryan Mueller on their work showing specialization in the use of organic carbon resources by heterotrophic bacteria in the ocean. They have shed light on the mechanisms of carbon cycling in the ocean, using a novel approach to track which microbes are consuming different types of organic carbon produced by common phytoplankton species.
Microbiology Graduate Student, Benjamin Americus (Dr. Bartholomew Lab) has received the prestigious MacVicar Animal Health Scholar Award for his work on fisheries conservation, evolutionary biology, and on the parasites of salmon. He receives a $5500 stipend and $500 for supplies/travel. Ben will present a seminar on his research in the near future.
ProQuest Distinguished Dissertation Award Becca Maher, Graduate Student in Dr. Rebecca Vega-Thurber's Lab, has won the Oregon State University CGS/ProQuest Distinguished Dissertation Award. These dissertation awards are made annually to students who have completed dissertations representing original work that makes an unusually significant contribution to their disciplines.
May 2021: Dr. Jerri Bartholomew and group are helping to reveal the grim outlook for Klamath River salmon this year. Over the past several weeks, an outbreak of the parasite Ceratonova shasta has ripped through young salmon throughout the lower reaches of the Klamath watershed. Driven by high temperatures and low flows out of Iron Gate Dam, the disease is resulting in .... a “catastrophic” fish kill. Dead in the water: Serious fish kill consumes the Klamath River |[...]

Research by Dr. Maude David, OSU Microbiology, indicates that children with autism may have a subtly different set of bacteria in their gut than their non-autistic siblings, according to unpublished data presented virtually on Tuesday at the 2021 Society for Neuroscience Global Connectome.
Gut bacteria associated with animal-based diet may mitigate risk of cardiovascular disease: “The connection between TMAO and cardiovascular disease has tended to focus the conversation on how animal-based diets cause negative health consequences,” said Dr. Veronika Kivenson, the study’s lead author and a postdoctoral fellow in the College of Science with Microbiology.

Saving Atlantis. Coral reefs cover only 0.1 percent of the Earth’s surface, but they’re home to 25 percent of all marine species, and they’re being lost at an alarming rate. Pollution, overfishing and[...]
April 2, 2020: A study that included the first-ever winter sampling of phytoplankton in the North Atlantic revealed cells smaller than what scientists expected, meaning commonly used carbon sequestration models may be over-optimistic. The OSU research into the microscopic algae, part of NASA’s North Atlantic Aerosols and Marine Ecosystems Study, was published today in the International Society for Microbial Ecology Journal. The findings are significant because the spring phytoplankton bloom in the North Atlantic “is probably the largest biological[...]
