“Pokemon”-new bacteria related to lung parasites, named after Pokémon

A analysis crew from the University of Cologne found beforehand undescribed bacteria in amoeba, that are related to Legionella and will even trigger illness. The crew of Michael Bonkowski from the Dr. Dr. Institute of Zoology has named a newly found bacteria “Pokemon” as a result of they reside in spherical amoeba, and Pokémon in video video games are related, they’re trapped in a ball.The outcomes of their analysis have been printed within the journal Frontiers of Cellular and Infectious Microbiology.

Legionella bacteria have lengthy been of scientific curiosity as a result of a few of them are recognized to trigger lung illnesses in people and animals-such as Legionnaires’ illness, which is brought on by Legionella pneumophila, typically presumably Is deadly. Legionella bacteria reside and multiply as intracellular parasites within the cells of the organism. The host of Legionella is particularly amoeba. The time period “ameba” is used to describe a wide range of microorganisms that aren’t intently related however have variable shapes and crawling actions by way of the prosthetic foot.

“We need to display screen the amoeba of the amoeba and choose a gaggle of amoeba for our analysis. These amoeba usually are not intently related to the beforehand studied host. This alternative falls on the amoeba group Thecofilosea, which is usually ignored by researchers,” explains Marcel Dominik Solbach.

In truth, the spherical Thecofilosea is the host organism of Legionella. In Proteus from environmental samples, scientists have been in a position to detect varied species of Legionella, together with two beforehand undescribed Legionella species and one undescribed species from the genus Legionella. “The outcomes present that the vary of recognized host organisms for these bacteria is way wider than beforehand thought. In addition, these findings point out that extra amoeba might turn out to be hosts for Legionella, and due to this fact might turn out to be illness transmission vectors. To examine additional, we at the moment are sequencing the whole genomes of those bacteria. Kenneth Dumack, who led the mission.

In the long run, these new discoveries will assist to higher perceive the connection between Legionella, and make clear the interplay between them and the host and the route of an infection to forestall human illness outbreaks.

The researchers named a type of bacteria they discovered “Pokemon”. The identify Pokemonas relies on the online game “Pokémon” (Pokémon), which celebrated its twenty fifth anniversary this 12 months. Most faculty kids, college students and their mother and father must be conversant in it. The identify implies the intracellular way of life of spherical amoeba bacteria, as a result of within the “Pokemon” collection of video games, little monsters are captured in balls, similar to “Pokemon” in Thecofilosea.
