Gastrointestinal microbiota composed of trillions of bacteria species bear important role in maintaining stable ecosystem inside the body. In gut, Enterobacteriaceae is present in very low densities below 108 cfu/g. Elevated number of enterobacteriaceae in gut can promote gastrointenstinal infection. Probiotics has been used for a long time in treating gastrointestinal related diseases. This reaserch aims to evaluate the effect of Enterococcus faecium IS-27526 supplementation as a novel probiotic from Indonesia on gut microbiota. Species of bacteria that were successfully identified using both morphology and physiology identification test on bacteria resulted in four major genera which are Citrobacter, Enterobacter, Serratia and Escherichia. Total bacterial and Enterobacteriaceae number were calculated between test and control group. Total bacteria population from Total Plate Count result was 222.67 x 106 cfu/ml in control group and 210.33 x 106 cfu/ml in probiotics induced group. TPC result for Enterobacteriaceae population from probiotics induced group was 11.33 x 106 cfu/ml and 12.00 x 106 cfu/ml for the control group. The use of Enterococcus faecium IS-17526 has significantly reduced the total bacterial count as well as enterobacteriaceae population in gut.
