Indole TEST :  ( Indole produced by microorganisms )

The ability to degrade amino acid to identify end products to differentiate bacteria.Indole can be detected to the culture growth ( Pure bacterial culture must be grown in sterile tryptophan or peptone broth for 24-48 hours before performing the test. ) by reaction with 5 drops of Kovac’s reagent to produce a red  or red violet colour. 

 

KOVAC’S Reagent - ( para-Dimethylaminobenzaldehyde in isoamyl alcohol and Concentrated hydrochloric acid ) 

Ehrlich Reagent - ( para-Dimethylaminobenzaldehyde in ethyl alcohol and Concentrated hydrochloric acid ) 

 

INDOLE TEST is suitable for 

Indole-Positive Bacteria that test positive for cleaving indole from tryptophan include: Aeromonas hydrophilia, Aeromonas punctata, Bacillus alvei, most Citrobacter sp., Edwardsiella sp., Escherichia coli,Flavobacterium sp., Haemophilus oxytoca, Proteus sp. (not P. shigelloides, Pasteurella pneumotropica, Streptococcus faecalis and Vibrio species. Bacteria which give negative results for the indole test include: Actinobacillus spp., Aeromonas salmonicida, Alcaligenes sp., most Bacillus sp., Bordetella sp., Enterobacter sp.,Lactobacillus spp., most Haemophilus sp., most Klebsiella sp., Neisseria sp., Pasteurella haemolytica, Pasteurella ureae, Proteus mirabilis, Pseudomonas sp., Salmonella sp., Serratia sp., Yersinia sp.50, 51 Kitasato's discovery that Escherichia coli could be distinguished from Klebsiella species (Aerobacter aerogenes) by virtue of its ability to produce indole initiated the detection of indole production as an accepted analytical tool for the bacteriologist
