For a while, new evidence has been accumulating linking the gut microbiota to brain function. A new paper published recently in Cell Reports, shows that the intermediary is a type of white blood cell, evidencing as well the relationship between […]

It all began in 1891, when Dr. William B. Coley, a bone sarcoma surgeon at the Memorial Hospital in New York, injected streptococcal organisms into a patient with inoperable cancer. He thought that the infection he induced would have the […]

Listeria monocytogenes is a food-borne Gram positive bacteria that causes the infection listeriosis. It is responsible for serious clinical manifestations including gastroenteritis, and meningitis and encephalitis in newborns, with 20 to 30 % of clinical infections resulting in death. […]

Bacteria are the workhorses for a large number of biotechnological processes. From different fermentation processes to insulin production, they are widely used in industry due to their efficiency, fast duplication times and ease of maintenance. But often their behaviour […]

Few weeks ago, a new report by WHO reveals that antibiotic resistance is now a major threat to global public health: “the world is headed for a post-antibiotic era”. One of the priorities is the treatment of urinary tract infections […]
