摘要
Abstract
A Bacillus strain BF3 ,which was isolated from the feces of healthy and adult broiler, was i-dentified as Bacillus subtilis by its cultural characteristics,morphological characteristics,physiological and biochemical properties and 16S rDNA sequence.Inhibition of the growth of enteric bacteria by Bacillus subtilis BF3 was studied.The results showed that the Bacillus subtilis BF3 could decrease the propagation of the Salmonella pullorum and Chicken Escherichia coli obviously in the course of incubation.The strength of the antagonism was influenced by the inoculation time of Bacillus and pathogenic.The Bacillus strain was inoculated firstly,the antagonism was the strongest.Bacillus and pathogenic bacteria were inoculated at the same time, the antagonism ranked the second.The Enteric bacterium was inoculated firstly,the antagonism was the weakest.And the Bacillus strain BF3 metabolites showed powerful ability to inhibit the growth of the Salmonella pullorum and Chicken Escherichia coli.关键词
