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…
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…
Earlier last month, researchers with the National Institutes of Health reported that many hospital plumbing systems are a ‘vast’ reservoir of drug-resistant superbug germs and other bacteria like Legionella. This report came after NIH officials had done checks of the plumbing at the their flagship hospital near Washington, D.C., checks which showed drains could be packed with bacteria and ultimately concluded that this issue is likely present at other hospitals. Now the report also mentioned that the superbugs are not very common anywhere else in the hospitals and as such, they are simply unlikely to be an overall threat to…
Over the course of the past month, we have not only covered various sporadic cases and outbreaks of Legionnaires’ disease, but have also tried to shine light onto other developments within the field. A seemingly simple question, however, has been on my mind as I continue to go through these stories; is there a vaccine that could prevent individuals from being at risk to Legionnaires’ disease? And if there is not a vaccine, then why not? Well the first question is relatively simple to answer; no, there are currently no vaccines for Legionnaires’ disease. There have certainly been attempts to…
The source of Legionella bacteria and where individuals contract Legionnaires’ disease can often be unexpected. In a study from researchers out of the University of Padua, it was found that two men contracted Legionnaires’ disease after using two separate car washes in Italy. And while the location may seem somewhat surprising, according to microbiologist Dr Tom Makin, a senior consultant at Legionella control in the UK, perhaps it shouldn’t be. Indeed Dr. Makin remarks that, “(C)ar washes are capable of generating the right sized aerosols that can be inhaled into the lungs where the Legionella bacteria cause infection, such as pneumonia.’…
In a study released late last year, the Center for Disease Control and Prevention found that cooling towers (CTs) were found to be a leading source of Legionnaires’ disease outbreak across the United States. These results were obtained by obtaining aliquots from various water samples collected during routine Legionella testing from approximately 196 cooling towers across eight of the nine continental US climate regions in order to control for regional differences. After examining these 196 samples, Legionella spp were found in 78 of the samples, L. pneomophila were isolated in approximately 53 of the samples, and L. pneumophila serogroup 1…
The Centers for Disease Control and Prevention‘s Morbidity and Mortality Weekly Report provided data that in 2015, 6,079 cases of Legionnaires’ disease occurred nationwide. Of those cases, 2,809 occurred in 20 states and New York City, and among that figure, 468 cases were possibly associated with health care facilities, while 85 of those definitely were. Of the 85 cases confirmed to be associated with health care facilities, 68 of them- or 80%- were associated with long-term care facilities, and and 15- or 18%- were associated with hospitals. Legionnaires’ disease is a type of bacterial pneumonia caused by exposure to Legionella bacteria. The bacteria…
Positive findings of Legionella bacteria were found throughout the water system in the Rio All-Suite Hotel and Casino in Las Vegas. The investigation came about after two guests contracted Legionnaires ’ disease following their stay at the Rio Hotel in March and April. Test results conducted by The Southern Nevada Health District following the second reported case of the disease showed the presence of the bacteria. The company is now taking action to remediate the problem and disinfect the water. Guests are being alerted and are being relocated while remediation is taking place. Legionnaires’ disease is a type of pneumonia…
According to a CDC report based on 27 different outbreaks investigated by the CDC from 2000-2014, released last year, found that hotels and resorts are the most common source of Legionnaires’ Disease outbreaks in the United States. Hotels and resorts were 25 percentage points ahead of long term care facilities and other health care related facilities. Senior living facilities, workplace, and community-associated outbreaks were each found to be responsible for 7% of Legionnaires’ Disease outbreaks. Travel associated outbreaks (hotels and resorts) were found to be the most common source of outbreaks but were also found to have the lowest median fatality rate at…
According to data from the CDC, the number of deaths caused by Legionnaires’ Disease has just about tripled over the past two decades. In 2002 there was 63 deaths directly attributed to Legionnaires’ Disease. The CDC reported 170 deaths caused by Legionnaires’ Disease in 2015, the most recent year that was analyzed. When Legionnaires’ Disease is taken into account as a contributing factor to death, the number of deaths in 2015 increases to 217. Legionnaires’ Disease is the underlying cause of death in 78.3% of fatalities associated with the disease. The data also shows that the mortality rate for Legionnaires’ Disease…
