In vitro experiment revealed that the zone of inhibition of probiotic 1 was higher than probiotic 3 followed by probiotics 2. In vivo experiment also revealed that the elimination of pathogenic Micrococcus sp.oxt from 1.54 x 1011 colony forming units (cfu)/ml to 2.50 x 101 by probiotic 1 was higher than; to 2.00 x 101 cfu/ml by probiotic 3 and; to 3.3 x 101 cfu/ml by probiotics 2. The present investigation confirmed the elimination of pathogenic bacterium, Micrococcus sp.oxt in both in vitro and in vivo experiments.
