title: [Invasive listeriosis in Valencian community, Spain, during the period 2008-2010].
abstract: BACKGROUND
  Listeria monocytogenes is an uncommon cause of disease, although in certain age groups (infants, elderly, pregnant women and immunocompromised) may be an important cause of meningoencephalitis, and bacteremia. The aim of this study was to detect the incidence of invasive listeriosis cases found in Valencia during a period of 3 years.
  
  
  METHODS
  A retrospective study of invasive listeriosis detected in the period 2008-2010 was carried out. The isolation of Listeria from a potentially sterile anatomical location was considered as "case". Data from the Microbiology Surveillance Network of Valencia (RedMIVA) were used as a source of information.
  
  
  RESULTS
  98 cases of invasive listeriosis were detected, of which 58% were men. The largest number of diagnosed cases belonged to the age range 60-80 years (63%). Bacteremic infectious become evident in 57 cases (58%), central nervous system lesions were located in 30 cases (31%) and infectious in sterile liquids occurred in the remaining cases (11%). In 90 strains (92% of cases) could be performed the sensitivity to antibiotics and all were sensitive to ampicillin. Incidence rates were: 0,73 cases/100.000 inhabitants in 2008, 0,70 cases/100.000 inhabitants in 2009 and 0,58 cases/100.000 inhabitants 2010.
  
  
  CONCLUSIONS
  The average rate of invasive listeriosis in Valencian Community in the period 2008 to 2010 was 0.67 cases per 100,000 inhabitants. Temporal or geographic clusters of cases were not detected.
