Age-Dependent Carriage of Kingella kingae in Young Children and Turnover of Colonizing Strains

Abstract

In a longitudinal study, Kingella kingae carriage rate was nil below 6 months of age, 1.5% at 6 months, 9.6% at 12 months, remained stable between 10.4% and 12.0% during the second year of life, and decreased significantly to 5.3% at 30 months. Replacement of carried strains occurred over time.
