Check out this very interesting article that states that bee hives that are more genetically diverse (have a queen that has mated with more than one drone, or male, bee) are not only less susceptible to pathogens and infectious disease, but they have higher contents of certain bacteria that we consider to be probiotic and healthy for the human immune system as well! The researchers hypothesize that these bacteria may help in the fight against CCD – Colony Collapse Disorder.
