Increase in Extraintestinal Infections Caused by Salmonella enterica Subspecies II–IV

Abstract

To garner information regarding site of infection and age and sex of persons infected with Salmonella enterica subspecies II–IV, we retrospectively analyzed data on Salmonella spp. infections in California, USA, 1985–2009. These subspecies were found to cause significantly more frequent invasive disease (e.g., bacteremia) than did Salmonella subspecies I strains.
