title: [Kingella kingae osteoarticular infections in children. A report of a series of eight new cases].
abstract: Kingella kingae is a Gram-negative bacillus which belongs to the Neisseriaceae family. Its involvement in osteoarticular infections is relatively recent.
  
  
  RESULTS
  We report eight cases of Kingella kingae osteoarticular infections that have been diagnosed at the paediatric surgical centre of Rouen University Hospital since October 1995. Six boys and two girls (mean age: 30.6 months) presented with osteomyelitis in six cases and arthritis in two. Only 75% of patients had a fever at time of diagnosis. The biological findings were slightly modified. All samples were obtained from blood, bone or joint fluid. These samples were systematically inoculated into a blood culture tube. Positive Kingella kingae culture was achieved in seven local samples and in one blood culture. All children received two antibiotics via intravenous injection while waiting for the bacteriologic results. Later, the antibiotic treatment (amoxycillin) was given per os. The mean duration of treatment was 33 days. Patients were given intravenous treatment for a period of only ten days. Six patients were followed up for a period of more than 18 months and outcome was always uneventful.
  
  
  CONCLUSIONS
  Kingella kingae is usually present in the nasopharyngeal mucosa and spreads in the blood due to various infections. Different types of Kingella kingae infection have been reported with a large frequency of osteoarticular infection.
  
  
  CONCLUSIONS
  This type of infection does not present any unusual characteristics as compared to other osteoarticular infections. Because of its antibiotic sensitivity treatment duration could be reduced. Kingella kingae is a fragile microbe and its culture is often difficult; therefore, it is important to use blood culture tubes to inoculate joint fluid and bone samples.
