Microalgae (which included cyanobacteria, coccoid
green algae, chrysophytes, individual cells and fragments, and relatively unbranched filaments of red, brown, and green algae) dominated 10 sample dates.
The bacterial cells can appear coccoid
, cocco-bacillary or filamentous.
Also, some coccoid
forms wrapped in a kind of sheath which joined others forming an elongated structure, similar to those described for the first time by Ramachandran Nair .

Helicobacter pylori," Journal of Medical Microbiology, vol.
More than 140 coccoid
species have been recorded on various Quercus species from the Palaearctic region (Kozar, 1998).
During the rainy season, the total biovolume reached its lowest values, the cyanobacteria assemblage was represented by coccoid
and filament forms, N[H.sub.4.sup.+] concentrations were high (15-21[micro]M) and DIN:SRP ratio was high (40-159).
An autopsy performed by the county medical examiner revealed visible colonies of coccoid
bacteria, which had formed in Stokes' heart, causing acute inflammation of the heart tissues, the presence of which was preserved on slides and confirmed by microscopic inspection.
He regarded the organism as highly pleomorphic with phases varying from small granules to fungal type elements, including coccoid
forms, mycelia and rod forms.
Alternatively, this microorganism could exist in the nose in an unculturable inactive coccoid
state, only to initiate proliferation and cause disease under specific circumstances.
pylori bacterium appears to survive in water in a coccoid
form, even in very cold water (22).
Far more resistant and sturdy structures are made by Enthophysalis major, a coccoid
cyanobacterium that colonizes the large sand ripples, as much as a meter wide, made in lagoons and channels by frequent changes in current direction.
Under these climatic, microclimatic, and substratum conditions chasmoendolithic coccoid
cyanobacteria may occur in exfoliating surfaces (Danin & Garty, 1983: Photograph 9; Danin, 1986b, 1992b).
