Abstract
Summary: A model system for the study of phage conversion ofSalmonella entericaserotype Enteritidis is reported. Temperate phages 1,2,3 and 6 from the phage typing scheme were used to convert several individually recognized phage types into others. Phage type 4 was converted to PT8, PT6a to PT4, PT6a to PT7, PT13 to PT13a and PT15 to PT11; some new phage lysis patterns were also detected.This model was used to examine the relationships between phage types within a previously denned clonal lineage, SECLIII, to establish whether or not Enteritidis likeSalmonella entericaserotype Typhi andSalmonella entericaserotype Paratyphi B possessed type determining phages. We were able to convert PT1 to PT20, and PT15 to PT11.Keywords
