Over the course of the past few weeks, we have covered cooling towers and how they can serve as potential breeding grounds for Legionella bacteria. This appears to be the case in Long Island as a school district there announced that Legionella bacteria was found in the cooling towers at three of their schools. According to the Sachem Central School District at Holbrook’s superintendent, James Nolan, the bacteria was detected in the cooling towers at Seneca, Sequoya and East schools after conducting scheduled testing in order to be in compliance with New York state regulations. Once discovered, the cooling towers…
Earlier this week, we wrote about Spartan Bioscience and how the company had partnered with the Public Services and Procurement Canada (PSPC) to conduct a study examining cooling towers at federal government buildings. The results from the test were a bit negative as it was revealed that around 39% of the cooling towers had tested positive for Legionella bacteria at levels greater than 10 bacteria per milliliter while approximately 8% of the cooling towers tested positive for Legionella levels that were greater than 100 bacteria per milliliter. Now, about a week later from when the initial results were revealed, the PSPC is coming…
About a month ago, we wrote about Spartan Bioscience and their rapid on-site Legionella DNA testing. Last Wednesday, Spartan Bioscience announced their results from a study examining Canadian federal government buildings. This 12-week long study tested 51 different cooling towers across Montreal, Ottawa, and Toronto and compared their weekly on-site Legionella DNA testing against the monthly Legionella culture testing that at the moment, tends to be the far more common method for testing. The Public Services and Procurement Canada (PSPC) designed and ultimately performed this study in collaboration with Spartan Bioscience, a notable partnership since PSPC is one of the…
Earlier this week, we posted about Baumholder, a US army base in Germany that had to decontaminate around 20 housing units after finding high levels of Legionella bacteria there. Now, just 35 miles away, officials at the Landstuhl Regional Medical Center are ordering the decontamination of the hospital’s water system after finding Legionella bacteria in two separate areas of the facility. According to the hospital’s spokeswoman Stacy Sanning, the inspectors had originally tested there on February 23 however only recently notified the Landstuhl Regional Medical Center a few days ago of the high levels of Legionella bacteria. Though it remains…
For today’s post, we are once again going to take a bit of a step back from the news and examine some of the fundamentals of Legionella bacteria and Legionnaires’ disease. With that in mind, today’s post will be doing a review of the basics regarding how testing for Legionella is done. Traditionally, Legionella is found by a culture on a buffered charcoal yeast extract agar. One very common procedure for detecting Legionella in water is to concentrate the bacteria before inoculating it onto a charcoal yeast extract agar along with some agents like polymixin, GVPC, vancomycin, glycine, and cyclohexamide in order to suppress any…
At the Baumholder Army Base in Germany, approximately 20 buildings were decontaminated after finding high levels Legionella bacteria. According to the base doctors, no one staying at the base tested positive for Legionnaires’ disease. Army officials explained their attempts to decontaminate the buildings last Wednesday and according to the commander of U.S. Army Garrison Rheinland-Pfalz Col. Keith Igyarto, workers are doing everything necessary to protect the health of everyone living in the base. The discovery of these buildings came about when the Army tested 124 buildings within the military base and community for Legionella bacteria this past February in order…
The subject of using big data to try and model for future outcomes has been a popular one in relations to numerous types of fields. Yet in regards to this post, one application for modeling which seems particularly interesting is in regards to epidemiology and specifically Legionnaires’ disease. Now the primary paper I could find dates back to March of 2011 however it does draw some interesting conclusions. Essentially they attempt to model a Legionnaires’ disease outbreak using symptom-onset data from several specific outbreaks in order to estimate the beginning and end of the release of Legionella. The researchers are…
Over the past few weeks, we have included several articles regarding the Quincy, Illinois Veteran’s Home Legionnaire’s disease outbreak and the state’s attempts to not only find out exactly what happened, but to also take steps to try and ensure this kind of severe outbreak can never happen again. As of yesterday, this process of figuring out next steps took a new decisive turn by having Gov. Bruce Rauner’s administration announce its plans to replace the residence halls at Quincy, Illinois veterans’ facility. The plan, which was revealed by the Illinois Department of Veterans’ Affairs Director Erica Jeffries, was initially…
Back in February, it was reported by KFOR that around six employees who worked inside the Robinson Renaissance Building had tested positive for Legionella bacteria. In addition, it was also revealed through lab results that the Legionella bacteria was located within one of the building’s cooling systems. Now new testing has been conducted on the downtown Oklahoma City building, testing which shows the building has been cleared of Legionella bacteria. This was revealed when KFOR was given additional information about the extensive testing which had taken place at the building since back in February when KFOR first received the information.…
Due to a Legionnaires’ disease outbreak at the Island Walk gated community at the West Villages development in North Port last Friday, the Sarasota County Health Department will be testing the pool as well as the spa area of the facilities. The environmental health director for the Sarasota County Health Department Tom Higginbotham said the test kits had arrived on Tuesday and that the water from the hot tub along with both pools would be tested. Mr. Higginbotham also mentioned that the health department’s investigation should take around two days and that while the spa and two pools are the focus of the investigation,…
