[Septic arthritis caused by Kingella kingae in children].

INTRODUCTION

Approximately 50% of cases of bacterial arthritis occur in childhood. Currently Kingella kingae is considered as an emerging pathogen.

CLINICAL CASE: A ten month old male patient presented joint immobility in right knee. Arthrocentesis was performed.Kingella kingae was identified. He received treatment with ampiciline for 14 days.

DISCUSSION: This pathogen colonizes the posterior pharynx.Isolation in solid culture media may be difficult.

CONCLUSION

It is essential to consider this pathogen when septic arthritis is suspected, and to routinely use blood culture bottles for processing samples of synovial fluid.
