Discovery of new bacterial genus creates the basis for further research into Legionellales infection pathways

Some bacteria of the order Legionellales are known to cause lung diseases in humans (and animals) - such as "Legionnaires' disease", which is caused by the species Legionella pneumophila and can sometimes be fatal.

Cologne researchers discover new Legionella species. Scientists from the working group of Professor Dr. Michael Bonkowski from the Institute of Zoology at the University of Cologne have discovered a new bacterial genus. In future, the researchers' new findings could help to better understand the relationships of Legionellales bacteria, as well as the relationships to their host organisms, but also the infection pathways, and thus better prevent outbreaks of infections and related diseases in humans.

The lifestyle of these intracellular bacteria, called "Pokemonas", which live in ball-shaped Thecofilosea amoebae, led to the choice of name: the scientists were reminded of the mini-monsters from the game "Pokémon". These are caught in spherical balls (so-called Pokéballs in the game).

Some Legionella species, such as Legionella pneumophilia, can multiply in drinking water due to unfavourable circumstances (stagnant water, biofilm formation). An excessively high concentration of these or other water-borne germs in tap water poses potential infection risks - especially for immunocompromised or elderly people.

Sterile water filters from Aqua free help you to protect your patients (hospital, nursing homes, medical practice) or your tenants from infections caused by water-borne germs.

The results of the research work of the researchers from the working group of Professor Dr. Michael Bonkowski from the Institute of Zoology (Terrestrial Ecology), under the direction of Dr. Kenneth Dumack from the University of Cologne has been published in the journal "Frontiers in Cellular and Infection Microbiology".
