Abstract
A comparison of life-history traits of 16 phages infecting E. coli reveals that although these viruses don't age, there is a trade-off between mortality and growth rate, which parallels that observed in many other species.

In the abstract, the mortality rate is described as being negatively correlated with multiplication rate, whereas it is positively correlated.
