Figure 4From: Evidence of microevolution of Salmonella Typhimurium during a series of egg-associated outbreaks linked to a single chicken farmVariable P2-P4 phage region in S. Typhimurium 135@ compared to SL1344, DT135 and DT12. Orange arrows indicate genes encoded in the P2-Hawk prophage sequence from S. Typhimurium 135@; the two cargo genes are darkened. Purple arrows indicate genes encoded in the P2 SopEÏ• phage from SL1344; the sopE effector gene is darkened. The P4 phage, conserved in SL1344, DT135 and S. Typhimurium 135@ is shown in blue. The integrase genes of each prophage are labelled (int).Back to article page
