Demand is skyrocketing in China for mice that mimic the diseases of humans
These numbers seem amazingly small.<p>I would expect there to be at least 10 billion lab-mice worldwide - enough for an almost 1:1 pairing with humans.   You can&#x27;t do large population scale studies of disease spread and antibiotic resistance etc. unless you have big populations.  We also have tens of thousands of man made chemicals we need to know the safety of, and a simple test on 100 mice isn&#x27;t going to detect the subtle side effects.<p>Mice are <i>so</i> easy to keep, they could be entitely mechanicly reared, and an experiment involving 1000 mice should be a simple matter of a few clicks on a computer.
