| Ants bring their own antibiotics |
Antibiotics from ants.

Plant diseases are becoming more and more threats to food production, and several of them are resistant to existing pesticides
.
A Danish study showed that even in places where insecticides are no longer used, ants can secrete compounds that effectively inhibit plant pathogens
Recently, it was discovered that African four-legged ants carry compounds that can kill MRSA bacteria
.
This is a terrible bacteria because they are resistant to known antibiotics and can attack humans
Recently, in a new study just published in the "Journal of Applied Ecology", three researchers from Aarhus University reviewed the existing scientific literature and found a surprising number of ant glands and ant bacteria.
These compounds can kill important plant pathogens
.
Therefore, the researchers suggest that people can use ants and their chemical defense "weapons" to protect agricultural plants
.
Ants live in densely gregarious nests and are therefore exposed to high-risk disease transmission
.
However, they have evolved their own anti-disease drugs
"Ants are used to living in dense societies, so many different antibiotics have evolved to protect themselves and their colonies
.
These compounds have a significant impact on a range of plant pathogens
According to this research, there are at least three different ways to apply ant antibiotics: directly using live ants in plant production, simulating ant chemical defense compounds, and copying ants encoding antibiotic or bacterial genes and transferring these genes to plants
.
Researchers have previously shown that carpenter ants that "move" to apple plantations can reduce the number of apples infected with two different diseases (apple head blight and rot)
.
Based on this new research, they further pointed out the fact that ants may be able to show people a new and sustainable way to protect plants in the future
