In a groundbreaking study using Merino sheep, researchers uncovered that tiny genetic variations within gut microbes can influence brain-related behavior.

For billions of years, bacteria have waged an ongoing arms race against viruses, evolving many defense mechanisms against the ...

The bacterium known as Pseudomonas aeruginosa is an unwelcome visitor in the human body. Serious infections can result when a ...

Edward A. Birge. Springer Verlag, New York. 2000. Pp. 559. Price £44.50, hardback. ISBN 0 387 98730 4. This is very much a pre-genomic, ‘E. coli-centric’ treatise on prokaryotic genetics with a ...

A toxin produced by bacteria as a defence mechanism causes mutations in target bacteria that could help them survive, according to a study published today in eLife. The finding suggests that ...

Scientists have made a pivotal breakthrough in advancing our understanding of how bacteria move and perform genetic exchange -- that could potentially lead to the development of new antimicrobial ...

Genetic variability across patients might play an important role in shaping the microbiome composition of wounds, thereby influencing the healing process, according to a new study. Genetic variability ...

Some genetic disorders—such as cystic fibrosis, hemophilia and Tay Sachs disease—involve many mutations in a person's genome, ...

Microbes are engaged in a never-ending battle, and they have ways of attacking each other as well as defense mechanisms. Viruses that infect bacteria are called bacteriophages, and it's generally ...

Genetic material pulled from 13 teeth found in a grave in Lithuania revealed infectious diseases that felled the French ...
