So, naturalists observe, a flea. Has smaller fleas that on him prey;. And so proceed ad infinitum. Swift had never heard of the microbiome, but he described it perfectly. We have bacteria that live on us, and bacteria have bacterial viruses that live on them Figure 1.
These viruses are called bacteriophages or phages. Viruses differ from bacteria in that they are not made of cells, but instead consist of a piece of DNA or RNA packed within a protein coat. Viruses are so small that we cannot see them with normal microscopes. To give you a sense of their size, if a phage were the size of the period at end of this sentence, then humans would be almost 4 miles 6 km tall!
Phages are the simplest and most abundant organisms on earth. Phages are really very beautiful Figure 2 and the way they reproduce is quite interesting. A phage attaches to a bacterium and injects its DNA into the bacterial cell. The bacterium then turns into a phage factory, producing as many as new phages before it bursts, releasing the phages to attack more bacteria. This means that phages can grow much more quickly than bacteria. In some countries, particularly in Eastern Europe, phages are actually used to treat bacterial infections.
Each phage can only kill one type of bacteria, so if a doctor knows what kind of bacteria is infecting a patient, it might be possible to give the patient a phage that can infect and kill that type of bacteria. Phages cannot infect human cells, and so they pose no threat to us. We have known for years that lots of phages are present in the gut, but we really did not know very much about them.
So, we started to study them. First, we separated the phages away from everything else in the gut, and then we sequenced them. We were amazed to learn that there are tens of thousands of different phages in the human gut. Most of them were completely unknown. Some of the gut phages are very simple and only have three genes, while others are huge and have more than genes.
If there are lots of phages present in the gut and they replicate very quickly, why do they not just wipe out all of the gut bacteria? Since it is a dry virucide, it leaves no residue and poses no risk of corrosion or damage to surfaces and devices.
