> Discoveries made by environmental virologists during the past decade or so have revolutionized our perception of the living world. It has become apparent that viruses are the most abundant living entities on Earth, outnumbering their hosts by an order of magnitude. The vast majority of viruses infect microbes ... Our inability to cultivate the vast majority (>99%) of microbes under laboratory conditions, however, has limited study of these interactions. We still do not know the hosts of most viruses.

Probing Individual Environmental Bacteria for Viruses by Using Microfluidic Digital PCR

> Viruses may very well be the most abundant biological entities on the planet. Yet neither metagenomic studies nor classical phage isolation techniques have shed much light on the identity of the hosts of most viruses. ... When we implemented this technique on the microbial community residing in the termite hindgut, we found genus-wide infection patterns displaying remarkable intragenus selectivity.
