Can pigeons and rats help our immune system?

Question

I was walkin down the street today and i saw a pigeon eating some old food and i wondered how the pigeon does not get ill eating that but if a human ate it we would get food poisoning so obviosuly the pigeon had a better immune sytem than me. so i wonder can we not extract the genes that make a pigeon immune to most diseases and transfer them to a human to make us immune?

Answer 1

Yes but what of the disease the rat/pigeon is susceptible to but humans arent!! If only it was that simple!!
