These hyperflagellated bacteria are attenuated in mice, and an LD50 for CS2007 could not be determined because mice did not die after inoculation with the highest dose. CS2007 also elicited protection in mice from challenge with wild type S. typhimurium VO:0002624 gene NCBI_Gene_ID: 1251968; PMID: 2496146
