Cockroaches, far from being a health hazard, could be a rich source of antibiotics.
A study of locust and cockroach brains has found a number of chemicals which can kill bugs like MRSA.
Scientists hope these could become a powerful new weapon to boost the dwindling arsenal of antibiotics used to treat severe bacterial infections.
The research was announced at a meeting of the Society for General Microbiology.
The researchers discovered nine different chemicals in the brains of locusts and cockroaches, which all had anti microbrial properties strong enough to kill 90% of MRSA (Methicillin-resistant Staphylococcus aureus) while not harming human cells.

"What makes harmless little green grasshoppers turn into brown, crop-chomping clouds of swarming locusts? Serotonin, according to a study published this week in Science.
When these insects go into swarm mode, they don't just get super social, they also completely change physically, becoming stronger, darker and much more mobile, says study co-author Swidbert Ott, a research fellow at Cambridge. In fact, he says, the before-and-after bugs look so different that, until the 1920s, they were assumed to be two unique species.
Burrows says that locusts can switch out of swarm mode, though it takes days rather than hours. He notes, however, that the about-face rarely happens in the wild, because the offspring of locusts that breed while swarming are born swarmers.
Today, locust invasions are controlled with pesticides that also wipe out other insects, note Burrows and Ott. This new research, however, paves the way for development of a chemical that would specifically inhibit serotonin production in the solitary grasshoppers, says Hojun Song, a postdoctoral researcher at Brigham Young University in Provo, Utah.
But remember, as Kung Fu's Master Po advised his young charge in the 1986 movie, "Do not go in fear, Grasshopper." Of the approximately 8,000 species of grasshoppers, only about 10 of them are likely to morph into swarming locusts, Burrows says. But, Song adds, more research should be conducted to determine whether other types of locusts also get hopped-up on serotonin.""What makes harmless little green grasshoppers turn into brown, crop-chomping... more
Scientists have always been baffled by the desert locust, which makes the perplexing transformation from shy loners to mindless eating machines when they get together. Serotonin has finally been tracked down as the culprit. Just looking at another locust will raise its serotonin levels. And a little contact will get the hormone flowing so strong that they eventually change color and personality.
Serotonin is, in all animals, the personality hormone. Too little, and you're depressed and isolated. Too much, and you're bouncing off the walls and licking people. The club drug Ecstasy causes a massive dump of serotonin into the blood stream. A group of people, all under the influence of Ecstasy will create a feeling of group mind, that all are connected as one.
Now imagine that all these people taking Ecstasy are already daily users of Prozac, and you've got a locust swarm.
The good news? Locusts under the influence of a serotonin inhibitor maintain their non-swarming, non-grain-guzzling tendencies, even when researches placed them in a fully hopped up swarm and pumped in some techno.Scientists have always been baffled by the desert locust, which makes the perplexing... more
