The ability of three strains of Listeria monocytogenes NCTC 7973, serovar 1/2a, NCTC 5124m serovar 4a, C-274 serovar 4b and one strain of L. seeligeri (SLCC 3954) to grow in TPB (Tryptose phosphate agar) at pH values between 5-9 and produce haemolysin has been investigated at two incubation temperatures. The minimum and maximum pH values at which haemolysin was detected were 5 and 9 respectively, at 20 degrees and 32 degrees C.
对三株单核细胞增生李斯特菌（NCTC 7973，血清型1/2a；NCTC 5124m，血清型4a；C - 274，血清型4b）以及一株斯氏李斯特菌（SLCC 3954）在两种培养温度下于pH值5至9之间的胰蛋白胨磷酸盐琼脂（TPB）中生长并产生溶血素的能力进行了研究。在20摄氏度和32摄氏度下，检测到溶血素的最低和最高pH值分别为5和9。
