| 摘 要： | 本试验旨在检测2株枯草芽孢杆菌对致病性大肠杆菌和沙门氏菌抑菌作用。以致病性大肠杆菌和沙门氏菌作为指示菌，采用2株枯草芽孢杆菌与大肠杆菌和沙门氏菌同时接种及先后接种的方法，对其与大肠杆菌和沙门氏菌的生物颉颃作用进行了研究。结果表明，先接种枯草芽孢杆菌再接种致病菌抑制作用最明显且在24 h时抑菌作用最强，同时接种枯草芽孢杆菌和致病菌抑制作用次之，先接种致病菌再接种枯草芽孢杆菌的抑制作用最弱。提示，2株枯草芽孢杆菌对致病性大肠杆菌和沙门氏菌都有一定的抑制作用，但抑制作用的强弱有差异，且与枯草芽孢杆菌和致病菌接种的时间长短有关。

| Abstract: | The effects of 2 Bacillus subtilis strains，Q4 and Q10 inhibiting the growth of E. coli and Salmonella.Regarded E.coli and Salmonella as indicators，investigated by the co-incubation， pre-incubation and post-incubation method.The results revealed that 2 Bacillus subtilis strains showed different ability to inhibit the growth of E. coli and Salmonella after incubating with Q4 and Q10， respectively.Having inoculated Bacillus subtilis and then co-incubation pathogens inhibition were most obvious in means of the strongest inhibitory effect at 24 h，at the same time，pre-incubation Bacillus subtilis and then co-incubation pathogen the inhibition was the weakest of all，the pathogens and Bacillus subtilis co-incubation were the second. From the former consequences that 2 Bacillus subtilis strains of Q4 and Q10 had inhibitory effect on the pathogen，but there were differences in inhibition，and related to the duration of Bacillus subtilis and pathogen inoculation. |
