      Following the discovery of a powerful antibiotic compound in the bloodstream of giant pandas, a new research claims cockroaches may be an indirect source of another powerful antibiotic.

      Emerald cockroach wasps are a parasitic species that lay their eggs on cockroaches, making the cockroach both a home and a source of food for the larvae.
When the wasp has identified its victim, it paralyzes the cockroach with a venomous sting.
The first sting prevents the roach’s legs from moving while the second delivers venom to the brain to prevent the roach’s escape reflex from kicking in.
The cockroach is then dragged into a burrow by the wasp, where it then lays an egg on the roach’s abdomen.
As the larva grows, it burrows into the cockroach and proceeds to eat its living host from the inside out.
 
 
     The problem with this is cockroaches are full of bacteria, virus and fungi that could potentially kill the larva.
When researchers from the University of Regensburg, Germany looked into how the larvae managed to survive off such an unsanitary food source, they were astounded to discover that the larvae actually secretes a cocktail of antibiotics that stop the growth of bacteria, fungi and viruses, thereby making the cockroach a fit home and meal for young larvae.
 
     “The cockroach is the only food source and cradle [for the larva],” explains Gudran Herzner, a biologist at the university.
“The larva has to protect, first, its food from degradation by microbes, and then it has to protect itself from food borne illnesses that these microbes might cause.”
 
     One of the compounds that are secreted by the larva has been identified as a powerful antibiotic that fights bacteria that is responsible for tuberculosis, a contagious disease caused by an infection of the lungs.
 
     While the antibiotic compounds used by the larva have been identified before, this is said to be the first study to have found it in one source: the emerald cockroach wasp larva.
