Excited to share that our recent work exploring how saliva modifies the displayed phenotypes of oral streptococci is now published and available in @mSphereJ ! A lot of talented undergraduates who are now in dental school or will be next year contributed

Red 🔴, Blue 🔵 and….Green 🟢? Just in time for July 4, check out our latest publication on the design and evaluation of new fluorescent strains of oral streptococci to use in microscopy applications, such as mixed-species biofilms https://t.co/NaWVgnGncf

AADOCR continues to support community water fluoridation as a safe, effective, and evidence-based intervention for the prevention of dental caries. https://t.co/7yDWIK1qA1 #caries #cavities #dentalcare #oralhealth

TWiM 330: More mouth microbiology 🦷 TWiM explains how to recode E. coli so it uses only one stop codon, and an exploration of the mechanisms of bacterial adhesion within dental plaque. Hosts: Vincent Racaniello, Michael Schmidt, and Michele Swanson. 📺 https://t.co/wYON90Q80k

Kaspar Lab at @AADOCR 2025 in New York City!! Excited to see Iris, Nicole and Jacob give their first presentations at a national conference #AADOCR2025

Tomorrow, 1:30pm. AADOCR in NYC. Honored to be a speaker alongside Drs. Jessica Mark Welch and @mbiojournal Editor in Chief @whiteleylab #microbiology #dentistry

We are excited and thankful to have received a NoA today from NIDCR on a new R03 examining nutritional niches within oral biofilms. This grant was reviewed last summer and went through council in the fall. Encouraging to see new grants being released given the circumstances

Supporting undergraduate research at @ugr_osu Denman Forum! Izzy Williams and Allen Choi, both senior undergraduates, presented today - both are first authors on lab publications. Congrats Izzy and Allen! Izzy also presenting at @AADOCR next week.

Bring home some hardware this year: -Nicole Fleming: Alumni Achievement -Robbie Bettinger: Alumni Merit, 3rd place DDS -Jarett Pittman: @DentsplySirona SCADA, 2nd place DDS -Jacob Harris: 1st place PhD -Lab: Basic Science Research Paper of the Year Congrats to all!

Kaspar Lab @OhioState College of Dentistry Research Day 2025!! @osuresearch @OhioStateERIK @OhioStateCTSI

This shows how undergrads/dental students can make meaningful research contributions. Unfortunately, with disruptions in NIH funding, my group may not be able to offer these opportunities in the future. Please, support research programs across the US for these students !!

Also assisting with the project were Emily and Madisen, former undergraduate researchers now in their D1 year at OSU, and Iris Shin a current D2 that made mutants in the summer between undergrad/D1 year. And of course Dan, now in med school at OU in Cleveland.

Jacob, as part of a dental school summer research project, tested a pyruvate oxidase mutant that decreases H2O2 production, as well as added catalase, to S. mitis / S. mutans coculture biofilms and determined this is the likely source of biofilm inhibition.

Through measuring hydrogen peroxide production, Izzy found this strain produces 5x more H2O2 than any other strain in our collection. Izzy will be presenting in a few weeks at @AADOCR in the NSRG Rising Researcher competition and has been an amazing undergrad researcher

In collecting data for another project, we noticed that this strain of S. mitis effectively inhibited S. mutans biofilm formation. A couple students in the lab, Izzy Williams an @OhioState senior, and Jacob Tuckerman, a current D3 dental student, ran with this to find out why

Big next few weeks for the lab, showcasing our research - out now in @AppEnvMicro is our new study showing a specific strain of S. mitis, ATCC 49456, effectively inhibits caries pathogen biofilm formation though high levels of hydrogen peroxide production!

Sometimes we forget about the importance of oral health, especially for adolescents. Support oral health research to keep our most vulnerable out of the hospital or staying home from school with something as simple as tooth decay! #SupportOralHealthResearch

Another new year, time for another semester directing first year Microbiology/Immunology

Kaspar Lab, Fall 2024 edition! Last lab meeting of the semester, and holiday white elephant gift exchange results! So thankful for all of these students, getting to be in the lab with them, and watching them grow over time. Wouldn’t be anywhere without them. Onwards to 2025!

We are currently looking for an Assistant Professor of Microbiology, within the area of microbial cell biology! https://t.co/dDd6C5nt5c

Pls share: Microbiology faculty position available at Texas A&M University.
