%X was evaluated in vitro the probiotic potential of native strains isolated from feces of wild chickens (gallus gallus) belonging to the genera lactobacillus sp., bacillus sp. and saccharomyces ; probiotic activity was determined by testing acid resistance (ph 3, 4, 5.6, 7), bile salts (0,05, 0,1, 0,15, 0,3%), tolerance to nacl (2, 4, 7,10%), antagonistic activity (salmonella spp, e. coli), production gas (glucose), growth temperatures (28, 37, 43 ¡ã c) and growth capacity. the most tolerant strains were identified by biochemical tests and carbohydrate fermentation. as a result it was found that three microorganisms: saccharomyces sp. (3), bacillus sp. (7) and lactobacillus sp. (14) have probiotic properties.
