| 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." |
