Legionella pneumophila in Norwegian naval vessels.
[legionellosis]
Little
is
known
about
the
occurrence
of
Legionella
pneumophila
in
water
supply
systems
on
board
ships
.
Our
aim
was
to
study
the
occurrence
of
L
.
pneumophila
in
the
water
supply
system
on
board
Norwegian
naval
vessels
as
the
basis
for
framing
preventive
strategies
against
Legionella
infection
.
Water
samples
were
collected
from
technical
installations
and
from
the
water
distribution
network
on
board
41
vessels
and
from
ten
water
filling
(
bunkering
)
stations
,
the
sampling
taking
place
in
two
rounds
separated
by
a
one
-
year
interval
.
The
samples
were
subjected
to
analysis
,
including
serotyping
and
genotyping
,
with
a
view
to
identifying
the
presence
of
L
.
pneumophila
and
of
free-living
amoebae
.
L
.
pneumophila
was
found
in
20
out
of
a
total
of
41
vessels
in
the
first
round
of
sampling
,
and
live
L
.
pneumophila
serogroup
1
was
isolated
in
seven
of
the
20
vessels
.
Free-living
amoebae
were
found
in
the
water
supply
system
in
most
of
the
vessels
,
including
all
the
vessels
with
L
.
pneumophila
.
The
same
genotype
of
L
.
pneumophila
was
identified
in
the
water
in
bunkering
stations
and
in
the
water
on
board
the
vessels
.
L
.
pneumophila
was
not
present
in
all
the
vessels
,
but
all
the
vessels
where
the
bacterium
was
found
were
also
contaminated
with
free-living
amoebae
.
We
have
demonstrated
the
probability
of
the
fresh
water
from
bunkering
stations
being
the
source
of
the
contamination
.
In
framing
preventive
strategies
,
importance
should
therefore
be
attached
to
identifying
the
source
of
contamination
and
the
presence
of
free-living
amoebae
,
as
a
premise
for
the
establishment
and
growth
of
L
.
pneumophila
in
onboard
water
supply
systems
.
