金黄色葡萄球菌增菌培养基增菌效果的比较与分析

目的通过选择好的培养基，以提高金黄色葡萄球菌（以下简称金葡萄）的检出率。方法用一定数量的大肠埃希氏菌与不同数量的金葡菌混合培养，观察不同增菌液的增菌效果。结果从SCDLP增菌液中中，金葡菌划分离到Baird-parker（以下简称B-P）平板、高盐甘露醇平板、普通琼脂平板上不生长，5个血平板上仅有1个生长；从7．5％氯化钠增菌液㈨中，金葡菌划线分离道上述平板均生长。结论自配的7．5％氯化钠增菌效果较好。

Objective To choose a better commercial enrichment medium that can improve the detecting rate of Staphylococcus anurans. Methods E coil and Staphylococcus anurans were cultured together with different culturing media. Then the enriching erect of each enrichment medium was determined. Results In SCDLP enriching medium, Staphylococcus anurans rules and separates B-P plat, the salt man nit plat, Ordinary agar plats, it doesn＇t grow. But only one Staphylococcus anurans grow in 5 blood plats. In 7. 5% Sodium chloride enrichment medium, Staphylococcus anurans rules and separates above-mentioned plat grow. Conclusion The effect of the 7.5% Sodium chloride enrichment medium is good.
