Extensive SEM examinations show a network of rod-shaped nanobacteria and small subspherical aggregates that strongly resemble coccoid
This unfavorable ratio may have also promoted the dominance of coccoid
bacteria, which may better assimilate nutrients because of their higher surface-to-volume ratio.
The most striking pattern was the absence of coccoid
cyanobacteria in any of the water column samples collected in 2006 (Fig.

to long, curved, clubbed forms, often resembling diphtheroids.

form of Helicobacter pylori as a morphological manifestation of cell adaptation to the environment.
Ornithosis is caused by a group of closely related, gram-negative, aerobic, nonmotile, coccoid
bacteria that are obligate intracellular bacteria.
Gudmundur Omar Fridleifsson, the Lagoon's chief geologist, experiments with the local strains of blue-green coccoid
and filamentous algae (said to have anti-aging properties) for use in future products.
A failure to detect H pylori may be attributable, at least in part, to the presence of coccoid
forms of H pylori, which develop as a temporary expression of the bacterium's adaptation to an extragastric environment.

31) The bacterium in biofilm consists of gram-positive coccoid
cells that divide and form microcolonies.
