Aeromonas species are ubiquitous Gram‐negative bacteria that inhabit a wide range of aquatic and terrestrial environments. Initially recognised as pathogens in fish, their role as opportunistic ...

A discovery has been made of the way in which the glgS gene (now renamed as the “surface composition regulator”, scoR) acts in bacteria and how the mechanisms involved in bacterial infection can be ...

Klebsiella pneumoniae infections occur in humans of all ages, however the highest risk groups appear to be infants, the elderly and the immunocompromised. One or more virulence factors may contribute ...

Scientists at the Department of Energy's Lawrence Berkeley National Laboratory have elucidated the process that activates the pathogenic genes of a bacterium. Publishing in Science Adavances, the ...

A new study has shown that the physical movements of the gut influence how enterohemorrhagic E. coli (EHEC) colonizes and activates its virulence genes in living hosts. Using zebrafish models, ...

Scientists have discovered the key chemical that signals Bacillus anthracis, the bacterium that causes anthrax, to become lethal. This finding opens up new avenues of exploration for the development ...

Bacteria are constantly moving by help of motility organs called flagella or pili to colonize new niches. Also, bacteria can exchange information, like “speaking to each other”, and thus acquire new ...

In many cases, the fundamental differences between harmless microbes and those that are considered to be harmful, i.e., common pathogenic, can be attributed to genes encoded on mobile elements such as ...

Metabolic dysfunction-associated steatotic liver disease (MASLD) is an independent risk factor for cardiovascular disease ...
