  • ABSTRACT Cells in desiccated Salmonella enterica serovar Typhimurium rdar ( r ed, d ry, and r ough) morphotype colonies were examined for culturability and infectivity after 30 months. Culturability decreased only 10-fold; however, cells were underrepresented on Salmonella selective media containing bile salts. These cells were mildly attenuated compared to the infectivity of freshly grown cells but still able to cause systemic infections in mice.
