ya I heard of this a few years back...but before they were looking at the coating of shell for antibiotics. The reason they are such a great source for this is because cockroaches go some pretty nasty places and need a good defense to keep from getting an infection. Some biologists say that they are as a species older than dinosaurs and are unchanged since then...because they are perfect in design. Did you know that they can survive a nuclear fallout? Some scientists were doing experiments on roaches and decided to nuke em with a high dose of radiation to kill them off...then put then in a bag and dumped them in the trash. They seemed dead, but they wer'nt they were just dazed. The escaped out of the bag, radioactive and all, into the neighboring community's houses.
Ohh and bug spray....ya we used raid on them...2 weeks later we found a bunch of abino roaches around the house.
They will probably outlive humanity and that is why we hate them
