【 摘 要 】

Using phenotype techniques, characterization was realized of species and serovars of 255 strains of Listeria isolated from human material: 220-86.3% 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 1/2 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.
