Raw Fish and Bacteria

Why is it that GBS bacteria affect fish species, in particular, the snakehead and Asian bighead carp?

Dr Leong: Bacteria, unlike viruses, are less species specific.

For example, the human immunodeficiency virus (HIV) can be found only in monkeys and humans, but not pigs, mosquitoes or rats.

Bacteria, however, can work on different animals and are not species-specific.

GBS has been identified in other fish, especially the tilapia fish, so it has a predisposition to affect fish - See more at THIS LINK.
