When
cultivated
on
rich
organic
media
containing
about
20%
of
animal
serum,
the
organisms
were
found
in
different
from
as
spheroid,
thin,
branching
filaments,
stellate
or
asteroid
structures
and
other
irregular
forms.
Similar
pleomorphic
(Grpleo=many;
morphe=
forms)
organisms
were
later
isolated
from
other
animals
as
sheep,
goats,
dogs,
rats
mice,
human
beings.
Similar
forms
were
also
found
growing
as
saprophytes
in
decaying
organic
matter.
These
were
named
as
pleuropneumonia
like
organisms
(PPLO).
The
species
discovered
by
Nocard
and
Roux
was
given
the
first
binomial
as
Asterococcus
mycoides
by
Borrel
at
(
1910),
meaning
rounded
and
stellate
forms
with
radial,
mold
like
filaments.
It
was
later
on
put
under
the
genus
Mycoplasma
by
Nowak
(1929)
and
these
organisms
are
now
commonly
called
as
mollicutes
or
mycoplasmas.
