dc.description.abstract | The
development
of
showerhead
biofilms
exposes
the
user
to
repeated
contact
with
potentially
pathogenic
microbes,
yet
we
know
relatively
little
about
the
content
of
these
aggregates.
The
aim
of
the
present
study
was
to
examine
the
microbial
content
of
tape-like
films
found
protruding
from
a
domestic
showerhead.
Culturing
showed
that
the
films
were
dominated
by
aerobic
-
and
-proteobacteria.
Three
isolates
made
up
almost
the
entire
plate
count.
These
were
a
Brevundimonas
species,
a
metalophilic
Cupriavidus
species
and
a
thermophile,
Geobacillus
species.
Furthermore,
it
was
shown
that
the
Cupriavidus
isolate
alone
had
a
high
capacity
for
biofilm
formation
and
thus
might
be
the
initiator
of
biofilm
production.
A
clone
library
revealed
the
same
general
composition.
However,
half
of
the
70
clones
analyzed
could
not
be
assigned
to
a
particular
bacterial
phylum
and
of
these
29
differed
from
one
another
by
only
1–2
base
pairs,
indicating
a
single
species.
Thus
both
the
culture
dependent
and
culture
independent
characterizations
suggest
a
simple
yet
novel
composition.
The
work
is
important
as
the
biofilm
is
fundamentally
different
in
form
(tape-
like)
and
content
from
that
of
all
previously
reported
ones,
where
variously
Mycobacterium
,
Methylobacterium
and
Xanthomonas
species
have
dominated,
and
extremophiles
were
not
reported. | en_US |
