Are You Looking For Answers To Legionella Questions?

See if you can stump Dr. Miller. We don’t think there are any Legionella questions that you can ask us that Dr. Miller and the Environmental Safety Technologies team can’t answer. 

Legionella Questions Dr Richard Miller

For over 40 years, Dr. Richard Miller has worked with Legionella.  Dr. Miller began his Legionella research at the University of Louisville in the fall of 1977.  The Legionnaires’ disease bacterium had recently been isolated by the CDC, and it didn’t even have a name yet.

Today, and since co-founding Environmental Safety Technologies over 25 years ago, Dr. Miller along with co-founder Shauna Weis and their team have answered
Legionella questions and provided clients with top-of-the-line Legionella testing services on building water systems.   EST’s testing is in accordance with
ANSI/ASHRAE Legionella Standard 188-2015 and the CDC Toolkit: Developing a Water Management Program to Reduce Legionella Growth and Spread in Buildings (2017).

Dr. Miller and the Environmental Safety Technologies team have extensive microbiology knowledge and experience.  This experience was acquired via:

  1. Laboratory research unraveling the physiology, metabolism, and pathogenesis of this bacterium.
  2. Legionella testing of cooling towers, potable water, whirlpool spas and decorative fountains for a growing list of clients, and…
  3. Teaching Legionnaires’ disease (and more than 30 other bacterial and fungal infectious diseases lecture topics) to the medical students at the University of Louisville.

With this experience, we believe we are up for the challenge to answer any Legionella questions you have about Legionella, Legionnaires’ disease, or about medical microbiology more broadly. Give us a shot and see if you can Stump Dr. Miller.

FAQ – Legionella Questions and Answers

Below are some frequently asked Legionella questions.  Some of these Legionella questions are very specific and challenging from our clients, partners, and prospective clients. We encourage you to try and Stump Dr. Miller and the EST team by asking any question that can cover a broad range of microbiology topics, including Legionella and Legionnaires’ disease.  In addition to all other infectious diseases (especially those that are water-borne diseases), Dr. Miller has knowledge of and has given lectures on, biofilm formation and biofouling processes, microbial-induced corrosion, biofouling detection, and control.   Dr. Miller and the EST team love the challenge of answering these Legionella questions. We encourage you to ask us questions by filling out the form to the right or below.  We are willing to bet you won’t be able to Stump Dr. Miller with your Legionella questions!

Regarding continuous secondary disinfection of domestic water – For facilities that must file a PWS permit and have licensed operators involved due to state regulations, have you encountered any issues with their insurance providers? Being a PWS – they are now taking on the responsibly/risk of altering and providing safe drinking water. Are insurance companies “okay” with the buildings taking on this added risk? Are facilities even addressing this or is it on their radar? If not and assuming PWS operations are not covered under their standard insurance does becoming a PWS increase rates, require them to get another policy, etc.2019-06-13T15:10:12+00:00

Although Dr. Miler is a Microbiologist and not an Insurance Expert or Attorney we did our homework and asked a well-known insurance company in the business of specializing in providing liability insurance to water treaters to provide out the best answer:

We were informed that although a general liability policy covering General Liability and Omissions and errors (O&E’s) will generally provide adequate coverage to the limit of the policy, the insurance company needs to be notified of any changes in the offerings (products and services) offered and sold by the company proposing to sell the devices.  Depending on the coverage of the general liability policy and the company that issues the policy this may be subject to change, and additional insurance premiums may be required.

Can a building potable water system or cooling tower have more than one type of Legionella growing together (i.e. more than one species of Legionella and/or more than one serotype of Legionella pneumophila)? If yes, how is this mixed Legionella phenomenon detected in a water sample sent to your lab, and if a mixed Legionella colonization is found, how is the health risk of this Legionella mixture determined?2019-05-09T11:38:58+00:00
Where is Legionella Found?2018-12-24T18:55:37+00:00

Legionella organisms can be found in many types of water systems. However, the bacteria reproduce to high numbers in warm, stagnant water (90°-105° F), such as that found in certain plumbing systems and hot water tanks, cooling towers and evaporative condensers of large air-conditioning systems, and whirlpool spas. Cases of legionellosis have been identified throughout the United States and in several foreign countries.

How is Legionellosis spread?2018-12-24T19:08:06+00:00

Outbreaks of legionellosis have occurred after persons have breathed mists that come from a water source (e.g., air conditioning cooling towers, whirlpool spas, showers) contaminated with Legionella bacteria. Persons may be exposed to these mists in homes, workplaces, hospitals, or public places. Legionellosis is not passed from person to person, and there is no evidence of persons becoming infected from auto air conditioners or household window air-conditioning units.

Who is at risk?2018-12-24T18:54:28+00:00

People of any age may get Legionnaires’ disease, but the illness most often affects middle-aged and older persons, particularly those who smoke cigarettes or have chronic lung disease. Also at increased risk are persons whose immune system is suppressed by diseases such as cancer, kidney failure requiring dialysis, diabetes, or AIDS. Those that take drugs that suppress the immune system are also at higher risk.

Pontiac fever most commonly occurs in persons who are otherwise healthy.

Legionellosis – Two distinct forms. Legionnaires’ Disease, Pontiac Fever and their symptoms2018-12-24T18:51:13+00:00

Legionellosis is an infection caused by the bacterium Legionella pneumophila. The disease has two distinct forms:

  • Legionnaires’ disease, the more severe form of infection which includes pneumonia. Patients with Legionnaires’ disease usually have fever, chills, and a cough, which may be dry or may produce sputum. Some patients also have muscle aches, headache, tiredness, loss of appetite, and, occasionally, diarrhea. Laboratory tests may show that these patients’ kidneys are not functioning properly. Chest X-rays often show pneumonia. It is difficult to distinguish Legionnaires’ disease from other types of pneumonia by symptoms alone; other tests are required for diagnosis. The time between the patient’s exposure to the bacterium and the onset of illness for Legionnaires’ disease is 2 to 10 days.
  • Pontiac fever, a milder illness. Persons with Pontiac fever experience fever and muscle aches and do not have pneumonia. They generally recover in 2 to 5 days without treatment. For Pontiac fever, the exposure time is shorter, generally a few hours to 2 days.
What is Legionella?2018-12-24T18:51:58+00:00

Legionella are rod-shaped gram-negative bacteria with over 40 known species. These bacteria survive in free-living protozoa and within biofilms that can develop in water systems.  The first documented outbreak associated with Legionella was at the 1976 Philadelphia convention of the American Legion.  It was here that 221 attendees contracted the disease and 34 died, hints the name “Legionnaires’ disease”.
