[Evaluation of a new colorimetric test (VIP) to determine the presence of lactobacillus in saliva].

This techniques using Rogosa agar modificated with green of bromocresol, placed into tubes (10 ml) containing 4 ml, was developed for qualitative estimation in saliva of lactobacilli in a quick form. We spotted with a pipette 0.1 ml of saliva dilution into different tubes with the culture medium previously mentioned. The tubes were incubated at 37 degrees C for 24 and 48 hours. The results obtained showed a great agreement with the number of latobacilli in the agar.
