Differentiate enteric gram-negative bacilli based on sulfide production, indole formation, and motility using InMicro® Prepared: SIM Medium (Sulfide, Indole, Motility). Sulkin and Willet reported that H2S detection is an important parameter to differentiate Salmonella and Shigella from other members of the family Enterobacteriaceae. Blazevic used a motility-indole medium to differentiate Klebsiella from Enterobacter and Serratia. Green et al., using smaller quantities of SIM Medium, demonstrated motility results could be interpreted after incubation periods shorter than 18-24 hours.
Sulfide, indole and motility have been combined in one tube for easy use. Indole is detected by adding Kovac’s Reagent or Ehrlich’s Reagent and it combines with para-dimethylaminobenzaldehyde to produce a red complex. The addition of agar forms a semisolid medium which is ideal for the detection of motility.
This medium contains casein and meat peptones that supply nitrogenous compounds and amino acids necessary for the growth of enteric gram-negative bacilli. Sodium thiosulfate is a sulfur source. Ferric ammonium citrate is an indicator that reacts with H2S produced by sulfate-reducing bacteria to form a black precipitate, ferrous sulfide. Organisms that possess the enzyme tryptophanase degrades tryptophan to produce indole which is detected by the addition of Kovac’s or Ehrlichs’s reagent. The addition of agar results in a semisolid medium suitable for the detection of motility.
