Virus-bacterium Associations Were Examined in the Natural Environment of a Termite's Hindgut

Caption

Virus-bacterium associations were examined in the natural environment of a termite's hindgut. Three general scenarios were seen. In the first (1) there was a one-to-one association: one type of virus matched one type of bacterium host. In the second (2) the host bacterium was associated with a diverse group of viruses, indicating perhaps a more ancient infection or a more susceptible host. In the third case (3) very similar viruses were seen infecting several different types of bacterial hosts. This study tested methods of examining virus-bacterium interactions in nature, rather than in vitro -- from a culture. It opens a new door to understanding the diverse and highly populated world of viruses and bacteria that we know so little about.
