Rats pose serious health threats to communities and farms, according to a new study. This is because rats readily pick up diseases from one environment and spread them to another. Most at risk are humans and poultry.
Pick up a text book on microbiology or human physiology. Chances are you’ll stumble across a reference to the number of microorganisms in the human body exceeding the number of cells ten-fold. But is this correct?

Researchers have pinpointed how Pierce's disease is transmitted from insects to grapevines. The disease costs California's grape and wine industries in excess of $100 million each year.
A new study has found how exercising while younger alters the types of gut microbes so that the composition is different than a person who takes up exercise later in life. These changes to the gut microbiome are beneficial.
The British government is seeking healthcare professionals and members of the public to become "antibiotic guardians." This is to help with using antibiotics more wisely and helping to conserve stocks.
Some scientists have been concerned that wastewater, where bacteria and antibiotics mix, could be seeding an increase in antibiotic resistance. A new study puts forward evidence that this is not the case.
Diets rich in fish oil compared with diets where lard is the predominant fat lead to very different types of bacteria being found in the guts. The bacteria appear to help with the health benefits of fish oil and the harmful effects of lard.
Listeria monocytogenes, in sufficient numbers on refrigerated food, can present the serious risk of listeriosis. Researchers have been investigating the growth mechanism of the bacterium to find a way of reducing infection rates.

This key experiment shows the successful protection of a phage-sensitive bacterial strain against a virus. Top-right - bacteria growing in the absence of a virus; Top-left - holes in the culture caused by an infecting virus; Bottom - when equipped with specific CRISPR defense system components, the bacteria became resistant to the virus.
