Kingella kingae as the Main Cause of Septic Arthritis: Importance of Molecular Diagnosis.

Background: Kingella kingae is an emergent pathogen causing septic arthritis (SA) in children.The objective of this study was to analyze the etiology of SA in children before and after the implementation of universal 16S rRNA gene polymerase chain reaction and sequencing (16SPCR) in synovial fluid.

Methods: Children ≤14 years with acute SA from a Madrid cohort (2002-2013) were reviewed.
