The document discusses laboratory tests used to identify enteric bacteria, including the IMViC test, TSIA test, and Sims test. The IMViC test checks for indole production, methyl red reaction, Voges-Proskauer reaction, and citrate utilization. The TSIA test checks for fermentation patterns and hydrogen sulfide production. The Sims test checks for motility, indole production, and hydrogen sulfide production. Control organisms used include E. coli, Enterobacter aerogenes, and Citrobacter freundii.
