A new selective medium for the isolation of Listeria monocytogenes (Lm), is described. The medium contained propolis, nalidixic acid, polymyxin B and rivanol as selective substances. The new medium (propolis-agar) was compared with two other selective media and one nonselective medium. No inhibitory effect was found on the 6 strains of Lm tested, and Lm was easily isolated from a mixture of Lm and contaminating bacteria. The selective effect was better than for the two other selective media tested.
本文描述了一种用于分离单核细胞增生李斯特菌（Lm）的新型选择性培养基。该培养基含有蜂胶、萘啶酸、多粘菌素B和利凡诺作为选择性物质。将这种新型培养基（蜂胶琼脂）与另外两种选择性培养基和一种非选择性培养基进行了比较。在所测试的6株Lm菌株上未发现抑制作用，并且能够轻松地从Lm与污染细菌的混合物中分离出Lm。其选择效果优于所测试的另外两种选择性培养基。
