Superbugs' Natural Nemesis — Bacteriophage

Many people may have seen some popular science videos featuring microbes that resemble alien spacecraft, with icosahedral heads, spider-like legs, and a tail pin. These remarkably unique-looking microbes are called bacteriophages, which are a very special type of virus while its host is bacteria, not animal. Their appearance may not seem natural, but what's astonishing is that bacteriophages have been around for 3 billion years, almost appearing alongside bacteria on Earth. They are virtually omnipresent, outnumbering all organic life forms on Earth combined.
