利用表型技术对255株人源李斯特菌的种类和血清型进行鉴定，其中220-863%来自可能侵袭性疾病的患者，35-13.7%来自定植的健康个体。这些毒株是从1969年至2000年在巴西的几个地区收集的。在0-10岁或41-60岁的个体中，单核细胞增生李斯特菌在脑脊液中比在血液培养中更常见，包括肾移植受者的样本。血培养株均检出单核细胞增生李斯特菌血清型。主要的血清型为4b（154-60.3%）和(t)/(2) a（74-29%）。在这项研究中，单核细胞增生李斯特菌引起侵袭性疾病，如脑膜炎或败血症，或定植个体，被确定。因此，应进一步研究临床和病理以及流行病学问题，包括与食源性传播相关的危险因素。
Using phenotype techniques, characterization was realized of species and serovars of 255 strains of Listeria isolated from human material: 220-863% were from patients with possible invasive disease, while 35-13.7% were from colonized healthy individuals. The strains were collected in several regions of Brazil from 1969-2000. In individuals aged 0-10 or 41-60 years old Listeria monocytogenes was isolated more often in cerebral spinal fluid than in blood cultures, including samples from renal transplant recipients. All Listeria monocytogenes serovars were detected in blood culture strains. The predominant serovars characterized were 4b (154-60.3%) and (t)/(2) a (74-29%). In this study, Listeria monocytogenes causing invasive diseases, such as meningitis or septicemia, or colonizing individuals, were identified. Consequently further studies focusing on clinical and pathological as well as epidemiological issues, including risk factors associated with foodborne transmission should be pursued.
