A strain of Listeria monocytogenes recovered from blood and cerebrospinal fluid had no detectable catalase activity, a characteristic used for primary identification. The sporadic occurrence of pathogenic catalase-negative strains highlights the need for a reconsideration of diagnostic criteria and questions the role of catalase in the pathogenesis of listeria infection.
从血液和脑脊液中分离出的一株单核细胞增生李斯特菌检测不到过氧化氢酶活性,这一特性用于初步鉴定。致病性过氧化氢酶阴性菌株的散发性出现凸显了重新考虑诊断标准的必要性,并对过氧化氢酶在李斯特菌感染发病机制中的作用提出了质疑。
