In a report published this week in the journal Nature Microbiology, researchers describe a never-before-seen antibiotic agent that vanquished several strains of multidrug-resistant bacteria. In rats, the agent — which the researchers dubbed malacidin — attacked and broke down the cell walls of methicillin-resistant Staphylococcus aureus and cleared the animals' MRSA skin infections within a day.

Bacteria that are resistant to antibiotics kill 700,000 people a year worldwide. If we don’t find new treatments, the annual death toll could rise to 10 million by 2050.

Researchers are tackling the problem of antibiotic resistance head on — by hunting for the genes that enable bacteria to become resistant to life-saving medications.

The increase in antibiotic resistant bacteria poses a major healthcare threat. In the face of an almost complete absence of new antimicrobial drugs in development, antibiotic resistance (ABR) has become one of the main public health problems of our time.

It’s worth noting that this continued antibiotic use, and continued and rising appearance of resistant bacteria on meat, is happening as the FDA has abandoned attempting to regulate livestock producers’ use of antibiotics, and has switched to a voluntary approach. Given the trend, I think it’s worth asking how well that voluntary approach is going to work.
