b
Nine non-Typhi Salmonella strains including six serovar Typhimurium strains, one serovar Enteritidis strain, one serovar Virchow strain, and one Salmonella group B strain were not detected using ABC and MABC media, since they did not produce α-galactosidase. Two strains of serovar Typhi failed to grow on MABC medium.
