Salmonella enteritidis phage types (PTs) 8, 13a and 24 could be distinguished by their virulence for BALB/c mice, their plasmid content and plasmid fingerprint. Virulent strains expressed long‐chain lipopolysaccharide and carried a 38 MDa plasmid indistinguishable from that in Salm. enteritidis PT 4. Avirulent strains were smooth but did not carry the 38 MDa plasmid. Possession of antibiotic resistance factors by some strains of Salm. enteritidis PT 24 did not contribute to the virulence of their host strains.
