Salmonella enterica serovar Typhimurium is a Gram-negative pathogen that causes gastroenteritis in humans and a typhoid-like disease in mice and is often used as a model for the disease promoted by the human-adapted S. enterica serovar Typhi. Despite its health importance, the only S. Typhimurium strain for which the complete genomic sequence has been determined is the avirulent LT2 strain, which is extensively used in genetic and physiologic studies. Here, we report the complete genomic sequence of the S. Typhimurium strain 14028s, as well as those of its progenitor and two additional derivatives. Comparison of these S. Typhimurium genomes revealed differences in the patterns of sequence evolution and the complete inventory of genetic alterations incurred in virulent and avirulent strains, as well as the sequence changes accumulated during laboratory passage of pathogenic organisms.
