This photo shows the contents of a lump on the inside of the donor's cheek. The exudate was mostly perfectly clear and thinly viscous with a discrete whiteish area. Under the microscope the white area is revealed as a huge biofilm of spirochetes.
This photo shows a gigantic biofilm in periferal blood in a chronically ill patient never treated for Lyme borreliosis and NHS negative for the disease. The donor's problem with 'sticky blood' was so severe that it was impossible to make a normal thin-film smear.
Another biofilm from the same donor's blood
