During a research project on the occurrence of Listeria monocytogenes 194 strains were isolated in southern West Germany during the years 1972 to 1974:154 from soil and plant samples (20.3%), 16 from feces of deer and stag (15.7%), 9 from old moldy fodder and wildlife feeding grounds (27.2%), and 8 from birds (17.3%). The highest number of isolates was obtained from uncultivated fields. The beta-hemolytic serovars 1/2b and 4b were were predominant; other serovars (some of them identified for the first time), including nonhemolyzing strains, have been encountered frequently. It is suggested that Listeria monocytogenes is a saprophytic organism which lives in a plant-soil environment and therefore can be contracted by humans and animals via many possible routes from many sources.
在一项关于单核细胞增生李斯特菌发生情况的研究项目中，1972年至1974年间在德国西南部分离出194株该菌：154株来自土壤和植物样本（20.3%），16株来自鹿和雄鹿的粪便（15.7%），9株来自陈旧发霉的饲料和野生动物觅食地（27.2%），8株来自鸟类（17.3%）。分离出的菌株数量最多的是未开垦的田地。β-溶血血清型1/2b和4b占主导；还经常遇到其他血清型（其中一些是首次鉴定），包括非溶血菌株。有人认为，单核细胞增生李斯特菌是一种腐生生物，生活在植物-土壤环境中，因此人类和动物可通过许多可能的途径从许多来源感染该菌。
