On Sunday, March 25th, it was reported that a Maine Maritime Academy graduate had won $310,000 in a lawsuit over Legionnaires’ disease which they contracted during their summer internship with LaBorde Marine Management LLC of New Orleans while aboard an offshore vessel in August 2013. The federal judge in the case awarded the graduate $150,000 for lost wages, another $150,000 for pain and suffering, as well as $10,000 for the treatment of post-traumatic stress disorder. The U.S. District Judge Ivan L.R. Lemelle concluded that LaBorde Marine Management LLC of New Orleans was negligent in keeping the intern safe from Legionnaires’…
Last week, researchers at the Technical University of Munich announced that they had developed a microarray rapid test which can detect Legionella in around 35 minutes. Now there is, in fact, a rapid test for detecting Legionella currently in clinics; urinalysis. But according to the head of the research group and the Chair of Analytical Chemistry and Water Chemistry at the Technical University of Munich PD Dr. Michael Seidel, the urinalysis test “serves only as a first indication and is not suitable for screening the water of technical systems,”. The research is part of the “LegioTyper” project which is funded by the German…
About 2 months ago, this page discussed some methods for reducing the risk of Legionnaires’ disease. That post, while informative, often felt a little wonky and clearly focused heavily upon the monitoring of the water system. While clearly designing an effective water system plan with monitoring is vital, this post intends to examine some more practical prevention methods for Legionella bacteria and the contraction of Legionnaires’ disease that can be incorporated in a water system plan. A good place to start is with the actual temperature of the water. To prevent the development of Legionella bacteria, it is suggested that water…
In another attempt to review some of the basics regarding Legionnaires’ disease and Legionella bacteria, this post will go over the mechanism of how an individual biologically contracts Legionnaires’ disease. To start, Legionella bacteria has to enter the lung, either through the aspiration of water which has been contaminated by Legionella bacteria or the inhalation of aerosolized water or soil which has been contaminated by Legionella bacteria. When in the lung, the Legionella bacteria are eventually consumed by a form of a white blood cell known as macrophages. Once inside of the macrophages within the lung, the Legionella bacteria will multiply which causes the…
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…
We recently wrote about the progress of a bill in the Illinois legislature which would promote the prompt notification in the case of an outbreak of an infectious disease like Legionnaires’ disease. There is, however, another push within these legislative efforts to also promote more rigorous Legionella monitoring. In order to keep Legionnaire’s bacteria from spreading, lawmakers are proposing, in addition to the notification requirements we discussed previously, a new water management plan which would require state operated residence facilities to monitor their potable water systems for Legionella. According to Senator Mike Hastings, “(V)eterans at these homes deserve homes that…
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…
A little over a month ago, we discussed a legislative attempt by State Representative Stephanie Kifowit from Oswego in regards to a proposed bill which would, “mandate prompt notification in the event of a future outbreak of an infectious disease” at every Illinois state Veterans home. It now appears as though there has been some traction on this proposed bill. As a review, the bill would require the notification within a day of a Legionnaires’ disease outbreak within any Illinois veterans’ homes. The more recent news, then, is that the bill was approved by the Illinois State House’s veterans’ affairs…
In today’s post, we will be taking a step back once again to review some basics surrounding Legionnaires’ disease. As such, a fundamental bit of information which may prove useful for future conversations is simply what the treatment for Legionnaires’ disease looks like in a broad way. The answer, in short, is antibiotics since in one way, a big part of treating Legionnaires’ disease is, put simply, treating a bacterial infection. A more specific answer, however, would include us listing some of the more effective antibiotics. As such, some examples include tetracyclines, quinolones, most macrolides, and ketolides. The reason these particular antibiotics are effective…
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…
