Journal of Environmental Health 2013 Abstracts - page 11

Over 3,900 water samples from 688 cooling towers were tested for
2008 in New Zealand
Of 80 (2.05% isolation rate)
isolates, 10 (12.5%) were
Legionella pneumophila
serogroup 1; 10 (12.5%) were
L. anisa
; nine (11.2%) were
serogroup 8; and one (1.2%) was
L. longbeachae
serogroup 2. Forty-one
isolates were
L. pneumophila
serogroups. Over 3,990 water samples
from 606 cooling towers were tested for
in 2009 in New Zealand. Of 51
(1.28% isolation rate)
isolates, 18 (35.3%) were
L. pneumophila
serogroup 1,
and 39 (76.4%) were other
L. pneumophila
L. pneumophila
serogroups were significantly associated with legionellosis cases
in 2008 and 2009.
L. longbeachae
serogroups were equally significantly associated with
legionellosis cases. This significant association of
L. longbeachae
with legionellosis
particularly of
L. longbeachae
serogroup 1 is unique in that part of the world. The
authors’ study also showed that the aqueous environment of the cooling tower is not a
natural habitat for pathogenic
L. longbeachae.
Regular monitoring and maintenance of
cooling towers have prevented outbreaks of legionellosis.
Direct From CDC: Kick Off 2013 With Exciting Workforce Development
Elaine Curtiss, MEd
With the New Year, many people make resolutions to improve upon themselves.
This month’s column highlights several training opportunities to help environmental
public health professionals improve upon their knowledge, skills, and abilities. These
trainings include environmental public health online courses, environmental assessments
for foodborne-illness outbreaks training, the Environmental Health Training in
Emergency Response (EHTER) course, and integrated pest management training.
Demystifying the Future: City of the Future: Part One
Thomas Frey
This month’s column is the first part of a series that explores the city of the future.
It talks about the diminishing value of proximity in our decisions on where to live, work,
and conduct business. It also explores how factors such as human interaction, trends,
money, and income will affect our future cities. The April
Journal of Environmental
will include the second part of this column.
