Tissue of dead solves mystery Fuzzy rod shapes in lab dish point to legionnaires' as cause of deaths at nursing home By CAROLYN ABRAHAM

From Friday's Globe and Mail
The answer, so anxiously awaited, came at last from the dead themselves.
Tissue swatches from the lungs of three deceased residents of the Seven Oaks nursing home in Toronto finally provided the key cells to be plucked and cultured.
By lunchtime yesterday, the puzzle's missing piece took shape in a petri dish: the clustered, fuzzy rods of Legionella pneumophila -- a craver of water, soil and lungs.
It was a surprise.
Doctors had suspected from the outset...

I saw an article on Radio-Canada television news earlier this week about hospital air moving equipment in a number of Quebec hospitals that appears not to have been cleaned in 20 or more years.I suspect that this might be the tip of the iceberg.

Ping Cui from Canada writes: It is not surprise to me and the battle is not over yet.
Based on my professional experiences and world-wide medical scientific research, I highly suspect that the source of legionnaires' disease comes from the building heating, ventilation and air conditioning (HVAC) system. Contaminated indoor air might have spread all over the building. Systematic measures are available on how to identify, evaluate and control legionnaires' disease, thus highly recommended to follow.
I am still worried about the people who live, work and visit the building. I am also worried about the adjacent daycare facility where kids and staff stay inside of the building where they may share the same building HVAC system.
Similar health complains have been received all over Ontario, especially in highly sealed buildings. These buildings rely on mechanical ventilation system to provide outside fresh air. More often, these problematic building's fresh air vales have been closed for months or even for years. Contaminated indoor air has been re-circulated all the time and provides a good chance to affect people's health inside these buildings. It is strongly recommended conducting a good competent professional inspection following appropriate procedures.

Stuart Cotts from Tillsonburg, Canada writes: Canadians don't know how fortunate we are.Once again Dr. Don Low
(and associates) is called to duty and has the answer.He
actually came down with SARS when he was in the middle of that
outbreak, and here he is again, risking lung and limb to get an
answer.Imagine if we would have lost him during the SARS
outbreak.
We had Fred Banting, now Donald Low.
He has my vote for the Order of Canada.
