A new ADA Forsyth microbiology study presents a novel approach to microbial imaging, introducing a sectioning-based fluorescence in situ hybridization (FISH) technique that enables spatial visualization of microbial communities in greater detail.
While preserving biofilm architecture, the new approach allows visualization of both Gram-positive and Gram-negative bacteria in a single biofilm by physically sectioning embedded biofilms.
The study from Professor Jessica Mark Welch and Research Professor Gary Borisy’s lab enables researchers to observe how the oral microbiome organizes itself in states of health or disease. ADA Forsyth researchers Jennifer Gundrum and Tabita Ramirez-Puebla conducted the study, which is published in Microbiology Spectrum.
