The
bacteria
are
a
group
of
great
diversity
with
a
procaryotic
cellular
organization.
Classification
of
bacteria
based
on
structural
and
functional
attributes
although
attempted
has
been
difficult.
Active
interest
in
classifying
bacteria
led
Chester
in
1899
and
1901
to
publish
the
manual
of
determinative
bacteriology.
This
manual
subsequently
was
modified
by
David
Bergey
into
what
is
now
known
as Bergey's
manual
of
Determinative
Bacteriology which
is
the
major
treatise
on
bacterial
taxonomy
since
its
first
publi.
cation
in
1923.
