From: Role of phage ϕ1 in two strains of Salmonella Rissen, sensitive and resistant to phage ϕ1
Strains chemical phenotypes and phage ϕ1 binding activities. a RRϕ1+ (lane b), RSϕ1- (lane c), and RW (lane d) display the smooth, rough, and semi-rough phenotypes, respectively. The reference marker (lane a) is the LPS from E. coli O55:B5. b RRϕ1+ strain (ϕ1-resistant and smooth) does not bind the phage; RW strain (ϕ1-sensitive and semi-rough) binds the phage, while RSϕ1- strain (ϕ1-sensitive and rough) displays an intermediate level of phage binding activity
