A research team at the University of Cologne has discovered a previously unexplained bacterium in the amoeba that is related to Legionella and may cause disease. Researchers from the working group of Professor Dr. Michael Bonkowski at the Institute of Zoology has named one of the newly discovered bacteria ‘Pokémon’ because they live in spherical amoebas, comparable to video game Pokémon trapped in a ball. Their findings are published in the journal. Frontiers in Microbiology, Cells and Infection.
Bacteria in sequence Legionellales It has long been of scientific interest as some of these bacteria are known to cause lung disease in humans and animals, such as “Legionnaires disease”, which is caused by Legionella pneumophila, and sometimes fatal. They live and multiply as intracellular parasites in the host organism’s cells. Especially the host of Legionellales are amoebas. The term ‘amoeba’ is used to describe many different microorganisms that are not closely related. But with variable shape and artificial displacement “We want to screen for amoebas for Legionellales And selected the amoeba group for our research that had no close correlation with the previously studied host, the choice fell into the Thecofilosea amoeba group, which is often overlooked by researchers, ”explains Marcel Dominik, Solbach.
And, of course, the spherical Thecofilosea serves as the host organism for Legionellales in Thecofilosea amoebae, from environmental samples, scientists can detect. Legionellales “There are many species, including two previously unexplained genus and one unexplained from the Legionella genus.” Studies show that the range of well-known host organisms of these bacteria is significant. Much wider than previously thought.In addition, the findings suggest that many amoebas may act as hosts of Legionellales And may be carriers of the disease for further investigation We are now sequencing the complete genomes of these bacteria, ”said project leader Dr. Kenneth Dumack.
In the future, these new discoveries will help to better understand how bacteria Legionellales How are they interrelated and clarified their interaction with their host, as well as the path of infection in order to prevent the spread of disease in humans?
The researchers named one of the bacteria they discovered as “Pokémon.” The type name “Pokémon” is a play on the video game franchise “Pokémon”, which celebrates its 25th anniversary this year. And most parents are likely familiar with this name, which describes the intracellular lifestyle. The bacteria in Thecofilosea amoebae are ball-shaped. Because in the “Pokémon” series, little monsters are captured as balls, just like “Pokemon” in Thecofilosea.
