Method Primary source [42] abstract: "Using both laboratory and environmental B. anthracis strains, [investigators] show that lysogeny can block or promote sporulation depending on the phage, induce exopolysaccharide expression and biofilm formation, and enable the long-term colonization of both an artificial soil environment and the intestinal tract of the invertebrate redworm, Eisenia fetida."
Comments P.361 right column bottom paragraph: "Findings by Schuch and Fischetti revealed that some of the prophages were able to profoundly alter the sporulating capacity of the bacterium in broth cultures (primary source). For example, after 1 d of incubation at 37 °C under good aeration, the ΔSterne strain produced about 5 × 10^8 spores/ml whereas lysogens carrying Wip4, Wip5, or Frp1 prophages did not sporulate (<10 spores/ml)."
