IDEXX Laboratories world campus in Westbrook, Maine IDEXX Laboratories, Inc., has developed an innovative water test called Legiolert™ to detect the presence of Legionella pneumophila in water sources, such as drinking water. This detection system can accurately depict the presence of Legionella pneumophila in potable water systems in seven days, as opposed to up to fourteen days using the customary culture methods of detecting the bacteria. Legiolert™ allows testers to skip steps of the usual testing procedures, such as colony counting and confirmation, which saves valuable laboratory time and reduces both the need for training and the risk of interpretation errors. Legionella pneumophila is the primary source of…

A new study by a team at Virginia Tech has linked the outbreak of Legionnaires’ disease in Flint, MI to the city’s decision to switch its water supply.

The results showed that the vast majority of outbreaks were caused by negligence on the part of maintenance employees who did not maintain biocides effectively, repair or change equipment on schedule, or did not adequately maintain the plumbing. These look like easily fixable problems, but it’s more complicated than it seems. The guidelines for preventing Legionella are not standards, and there are virtually no laws requiring specific Legionella prevention. This means…

         The marvel of modern medicine has drastically changed the way society functions on an everyday basis. Obviously the benefits of the advancements from the past century outweigh the drawbacks, but some issues have arisen from our progress that threaten the very purpose for which the advancements were made. For instance, the discovery of the first antibiotic, Penicillen, in 1928 by Alexander Fleming was one of the most groundbreaking advancements in modern history, and has allowed for the treatment of bacterial infections since. This greatly reduced the death rate and pioneered a new realm of medicine that has been…

   Taking a shower is a staple of personal hygiene, and is generally considered a necessity. It is important to stay clean, and showers provide us with that luxury, but the environment that cleans us can also house a number of harmful substances and organisms if not properly maintained. Mirror posted an article detailing a few different ways “your shower could kill you”, and while the article is a little more alarmist than necessary it does provide some interesting facts on a few different bacteria, fungi, and pathogens that can help identify preventative measures. Additionally, the article identifies which populations are…
