Method "Cells were observed living or fixed in OsO4 vapours using Nomarski Interference microscopy. For electron microscopy cells were fixed in 1% OsO4 and 5% glutaraldehyde in filtered (0.2µm) seawater in centrifuge glasses for about 15 min."
Comments "The cells measured 4–5µm. The overall shape of the cells was ovoid. From one side they appeared ovoid and from a perpendicular view they appeared spherical (Fig. 1). In the anterior end there was a prominent flagellar tuft that was easily visible even at a low magnification. It stretched about 3/4 of the cell length when viewed from the ovoid side, but when viewed from the side where the cells had a circular transect, it appeared narrow-from this angle it could sometimes be observed that the flagella emerged from a longitudinal depression on the cell surface. Superficially, the living, rapidly swimming bacterium appeared more like a small unicellular eukaryote than a prokaryote organism."
