The superbug is tthe result of indiscriminate use of drugs from poultry farms, to big agri-business where they are using it in the feed for cattle for pig, even for fish/shrimp farms.

You should expect the bugs to develop immunity to the anti-biotic "toxins".

The interesting thing is that I think it was in Sweden where they have banned anti-biotic use in the feed and can now only be used if the animal is sick. Wtihin three years of the ban, the superbug disappeared.

The reason for the loss of immunity has to deal with a rather simple concept: an organism has only finite resources, if it develops a immunity to a new threat, it is generally at a loss of some other traits. When anti-biotic was removed from their environment, the immunity no longer served them as a useful trait. And it becomes a burden rather than an asset, thus more pressing or needed traits are expressed while the immunity to the anti-biotic traits are turned off or lost.

We should only use anti-biotics only when we really need it. not for a simple cold or flue... The abuse of anti-biotic is another source of major concerns of the environment.

This is worrysome though...since I'm alergic to Cipro.
