Comments P.611 left column: "A current estimate based on these measurements is that there are ∼10^31 individual tailed phage virions in the global biosphere—enough to reach for 200 million light years if laid end to end—and measurements of population turnover suggest that it takes roughly 10^24 productive infections per second to maintain the global population (primary sources)." Primary source [267] abstract: "Every second, approximately 10^23 viral infections occur in the ocean. These infections are a major source of mortality, and cause disease in a range of organisms, from shrimp to whales. As a result, viruses influence the composition of marine communities and are a major force behind biogeochemical cycles."
