Legionella on the rise – Swiss government deploys task force

The number of cases of Legionnaire’s disease in Switzerland has increased by 35 percent since 2016. The Swiss government wants to stop the epidemic with a task force according to the Sonntagsblick.

Factsheet: Viable but non-culturable bacteria

 

what are vbnc bacteria?

What are VBNC bacteria?

The viable but non-culturable (VBNC) state is a unique strategy with which bacteria respond to unfavorable environmental conditions. In the VBNC state bacteria have a low metabolic activity and often do not grow or divide. Nevertheless, they are viable and in some cases, they can still be infectious.

Why are VBNC bacteria a problem?

As some of the VBNC bacteria can still be infectious and cause disease, they are considered a threat to humans and animals. Importantly, the standard method for detection of many bacteria in food and drinks, is based on cultivating bacteria in culture media. Because VBNC bacteria usually do not show growth on agar plates or in liquid culture media, they are not detected by the standard method.

Examples of pathogens that can enter the VBNC state

• Legionella pneumophila
• Listeria monocytogenes
• Pseudomonas aeruginosa
• Salmonella typhi
• Salmonella typhimurium
• Streptococcus faecalis

How can VBNC bacteria be detected?

The combination of immunomagnetic separation of target cells and detection by flow cytometry via fluorescent antibodies is fast and reliable.
rqmicro successfully adapts this technology, and is thereby able to provide solid results for VBNC while keeping the cell integrity intact.

Check out this page to find out more about rqmicro’s solution on VBNC detection.

Viable but Nonculturable Bacteria: Food Safety and Public Health Perspective

Increase of Legionellosis cases in Europe – Infographics July 2017

 

The number of cases of the potentially fatal Legionnaires’ disease seems to be rising in Europe according to the July 2017 Legionnaires’ disease surveillance and outbreak report. It concludes that there is a lack of rapid and reliable control measures for water systems to prevent outbreaks.

Infographics - Legionnaires' disease in Europe rqmicro July 2017

Preventing outbreaks with efficient monitoring

One highly efficient means of preventing Legionellosis outbreaks is the regular and close monitoring of water systems, which is of particular importance for facilities like hospitals with transplant programs or elderly homes (Tablan O.C., 2003). The accredited standard method for Legionella detection, ISO 1173, is based on cultivating Legionella on plates, which can lead to variable results and takes up to 14 days. One reason for this is that a non-negligible portion of Legionella present in a sample do not grow on agar and is thus not detected by the standard method – the viable but non-culturable fraction of cells. Additionally, competing flora often overgrows agar plates and thereby prevents growth of Legionella. Therefore, the accuracy and reliability of the data acquired with the standard method is neither satisfactory nor sufficient for the evaluation of water systems.

The rqmicro method provides highly precise and fast solutions:

  • Separation, concentration and purification of target cells from any matrix in 1 -2 hours instead of 14 days – Rapid testing method provides immediate process feedback
  • Getting rid of 95% of the competing flora – Delivery of ready-to-use samples for cultivation on agar plates, flow cytometry, PCR, microscopy, etc.
  • Detection of viable but non-culturable bacteria – Minimizing the risk of not only Legionnaires’ disease but also Pontiac fever
  • Automatization & easy implementation – Limited training required

rqmicro’s vision is that consumers worldwide benefit from water and food which is free from microbiological contamination. A crucial step towards realizing that vision is to detect pathogens in a quick and accurate way. Our CellStream instrument and the test kit for Legionella pneumophila SG 1 represent an important step towards the realization of this vision.
