Interesting article from TheBetterHealthGuy.com: http://phys.org/news/2013-06-classic-microscopy-reveals-borrelia-bacteria.html Excerpt: Filming the bacteria The two scientists are pretty much alone in what they are doing: investigating samples of living blood under the microscope - over time. They have looked at the blood of a large number of people who suspect that they are chronically ill following a tick bite. "We study the behaviour of the bacteria directly through the microscope. We have taken thousands of pictures, and we film their movement pattern in real time or with a time lapse. This allows us to see how the bacteria enter and leave the blood cells and swim around in the blood plasma. These are powerful methods, but nobody uses them any longer", says Laane. He himself is regarded as one of the foremost microscopy experts, and he has been studying bacteria for over 50 years.
