Abstract
From 195 strains of Salmonella, 175 (89.8%) produced tetrathionate reductase (TTR). TTR-negative Salmonella were found in 7 out of 31 serotypes examined: S. paratyphi A, S. paratyphi B, S. typhimurium, S. paratyphi C, S. thompson, S. typhi, and S. enteritidis. TTR-negative S. paratyphi B and S. thompson have not previously been reported. Production of TTR is valuable for the subdivision of some Salmonella serotypes into TTR-positive and TTR-negative variants.Examination of 362 strains of Enterobacteriaceae for TTR confirmed that Escherichia coli, Shigella, Klebsiella, and Aerobacter cloacae (enterobacter) are TTR-negative, while Salmonella, Citrobacter, and Proteus are usually TTR-positive.
