Bacterial viruses “overheard” signals from other species about hibernation. It hurt themselves
Bacterial viruses have proven capable of reading chemical signals from other species indicating how many bacteria are still available for capture, and using this information to decide whether to enter dormancy or actively replicate. However, this "eavesdropping" is only useful for the viruses that produce these chemical signals themselves, not for those that read them. Since bacterial viruses are being explored as a means of combating antibiotic-resistant infections, the ability to influence the behavior of these viruses will improve the effectiveness of such measures.
