NewsNew imaging approach lifts lid on microbial adhesive interactions
Scientists have identified many types of bacteria in the mouth, but many problems remain in understanding how they work with one another. One of the problems is that microbes assemble themselves into densely packed multi-species biofilms. Their density and complexity pose acute difficulties for visualizing individual cells and analyzing their ...
