Bioinformatics platform for the genome-based taxonomical classification of bacteria and archaea

Researchers develop Type Strain Genome Server (TYGS)

23-May-2019

"TYGS is an automated high-throughput platform for state-of-the-art genome-based taxonomy", is the title of the paper published in the current issue of the internationally journal Nature Communications. In this paper, Dr. Jan P. Meier-Kolthoff and Ass. Prof. Dr. Markus Göker, both of the ...

Over-fed bacteria make people sick

17-May-2019

Since the end of the Second World War, along with the growing prosperity and the associated changes in lifestyle, numerous new and civilisation-related disease patterns have developed in today's industrialised nations. Examples of the so-called "environmental diseases" are different bowel ...

Bacteria causing infections can be detected more rapidly

A fluorescent molecule for screening Gram-positive bacteria

09-May-2019

Two years ago, a group of infants died at the university hospital and it was found to be Gram-negative bacteria that caused their death. The Gram-negative bacteria turn into pink color and Gram-positive bacteria turn into violet color when stained using the Gram stain which is a bacterial ...

Pathogens find safe harbor deep in the gastric glands

06-May-2019

Scientists have long tried to understand how pathogenic bacteria like Helicobacter pylori, a risk factor for stomach ulcers and cancer, survive in the harsh environment of the stomach. In a new study in the open-access journal PLOS Biology, researchers led by Connie Fung and Manuel Amieva at ...

Fleming’s method in miniature

02-May-2019

Scientists in the Department of Biosystems Science and Engineering at ETH Zurich in Basel have developed a method with which they can quickly test a very large number of molecules for antibiotic effect. With it, they have already successfully discovered new antibiotic candidates produced by ...

Bacteria reveal strong individuality when navigating a maze

26-Apr-2019

Researchers from ETH Zurich demonstrate that genetically identical cells exhibit differing responses in their motility towards chemical attractants. Average values hide the full picture when it comes to describing the behaviour of bacteria. Although they are considered the simplest of all life ...

How plants defend themselves

Plant immune system detects bacteria through small fatty acid molecules

16-Apr-2019

Like humans and animals, plants defend themselves against pathogens with the help of their immune system. But how do they activate their cellular defenses? Researchers at the Technical University of Munich (TUM) have now discovered that receptors in plant cells identify bacteria through simple ...

A dust-up: Microbes interact with harmful chemicals in dust

Microbes in household dust can break down harmful chemicals

15-Apr-2019

The dust that settles throughout our homes and offices almost always contains bits of chemicals that can cause problems for the human endocrine system, scientists say. But a new study indicates that the microbes we track into buildings--the microscopic bacteria and other microorganisms that ...

First bacterial genome created entirely with a computer

The method has the potential to revolutionise biotechnology

03-Apr-2019

Scientists at ETH Zurich have developed a new method that greatly simplifies the production of large DNA molecules containing many hundreds of genes. With this method, they have built the first genome of a bacterium entirely designed by a computer algorithm. The method has the potential to ...

A social bacterium with versatile habits

25-Mar-2019

Related individuals of a soil bacterial species live in cooperative groups and exhibit astonishing genetic and behavioural diversity. Many living systems share a fundamental capacity for cooperation. Plants and animals are made up of billions of cells that communicate with one another, carry out ...
