Eickelboom filament type 1863 is most commonly observed dispersed in solution or occasionally near the edges of the floc at 1000x oil-immersion microscopy. The cell shape resembles small sausage-like rods typically 0.8-1.0 µm in width, 1-1.5 µm in dimension, and generally not exceeding 75 µm in length. Septa (cross-walls) are visible, and no sheath is present. Literature by Dr. David Jenkins, Dr. Michael Richard, and others associate type 1863 filament morphology with fat, oil and grease.
At a genetic level and based on our ongoing project of comparing as many micro to DNA samples as possible, filament type 1863 is most
