An investigation of 83 strains of Salmonella enteritidis phage type 30 showed that these bacteria were unusual in expressing either trace amounts of, or no, lipopolysaccharide (LPS). Regardless of whether strains expressed LPS or not, or carried a 38 MDa mouse virulence' plasmid, these strains were avirulent for BALB/c mice.
