Cockroach Brains May Hold New Antibiotics?
Insects naturally kill deadly MRSA and E. coli bacteria, experiment shows.
That's because the central nervous systems of American cockroaches produce natural antibiotics that can kill off bacteria often deadly to humans, such as methicillin-resistant Staphylococcus aureus (MRSA) and toxic strains of Escherichia coli, scientists said this week.
Two species of locust tested so far also have the same bacteria-killing molecules in their tiny heads.
The findings suggest that the insect world—which makes up 80 percent of all animals on Earth—may be teeming with new antibiotics, said study co-author Simon Lee of the University of Nottingham in the U.K.
Such a discovery is crucial, because scientists are scrambling to combat strains of several infectious diseases, including MRSA and E. coli, that are resistant to
