ABSTRACT Bacillus cereus as an endemic soil-dwelling rod-shaped bacteria that can cause food-borne illness is harmful to humans while it is true that other strains can be beneficial as probiotics for animals. This characteristics of B. cereus made way in determining its effectiveness as protectant and eradicant to selected fruits and vegetable pathogens such as Klebsiella pneumonia Alcaligenes spp. Xanthomonas spp. and Proteus vulgaris. Through In-Vitro analysis B. cereus as a protectant was most effective within 12 to 24 hours as antagonist against Alcaligenes spp. and Klebsiella pneumonia but not against Xanthomonas spp. As protectant for 36 to 48 hours B. cereus was most effective antagonist against Proteus vulgaris but not against Xanthomonas spp.Bacillus cereus as an eradicant for 24 hours was not effective as antagonist against all pathogens but for 48 hours it was most effective as antagonist against Alcaligenes spp but was not effective against Klebsiella pneumonia.
