LONDON — Cockroaches and locusts, which are widely hated for their dirty image, could actually be more of a health benefit than a health risk, according to the Daily News and Analysis.
Scientists at Nottingham University have discovered that the insects contain powerful antibiotic molecules in their brains that could be used to develop new treatments against methicillin-resistant Staphylococcus aureus (MRSA) and Escherichia coli (E. coli), the article stated.
According to the article, scientists have identified up to nine different molecules in the tissues of cockroaches and locusts that are toxic to bacteria and they hope will pave the way for new treatments for multi-drug resistant bacterial infections.
The tissues of the brain and nervous system of the insects were able to kill more than 90 percent of MRSA and E. coli bacteria, without harming human cells, the article noted.
