The gene for heat shock protein 60 (HSP60) was amplified from the DNA extract of Salmonella enterica serovar Typhimurium strain (LT2), ATCC 19585, using Polymerase Chain Reaction (PCR). The HSP60 gene was partially sequenced, inserted into expression vector and cloned into a competent Escherichia coli. The expressed recombinant HSP60 protein was purified by Ni-NTA affinity chromatography. Immunization of BALB/c mice with the purified recombinant HSP60 protein resulted in a significant anti-HSP60 antibody titers. The groups of the immunized and control mice were challenged with lethal doses of S. Typhimurium (LT2) ATCC 19585. Immunized mice had a higher survival rate than control mice suggesting the protective value of the recombinant HSP60 protein used for vaccination.
