目的探索乙型溶血性链球菌的有效检测方法,为提高此类检测检出率提供依据。方法用合成和自制1%葡萄糖肉汤及匹克氏肉汤增菌,将食品染菌并检测其存活期。结果皮克氏肉汤增菌效果最佳,奶制品及其它营养丰富的食品中的乙型溶血性链球菌存活期较长。结论乙型溶血性链球菌增菌液用匹克氏肉汤效果最佳。不含蛋白质的碳水化合物,不需要进行该菌的检测。 Objective To explore the effective detection of hemolytic streptococcus B, to provide the basis for improving the detection rate of such detection. Methods The synthetic and homemade 1% dextrose broth and Piccolin broth were added to inoculate bacteria and their survival was tested. Results Piccolin broth had the best bacteriostasis effect, and B. thrombolyticus in dairy products and other nutrient-rich foods had a longer survival time. Conclusion Streptococcus hemolyticus Streptococcus bovis Broth with the best effect. Protein-free carbohydrates do not require detection of the bacteria.
