Summary |
Introduction |
Staphylococcus aureus, Kingella kingae and β-hemolytic streptococcus are presently the most frequently identified bacteria in child haematogenous osteoarticular infection.
Objective |
To determine the microbiological profile (bacteria and antibiotic susceptibility) of osteoarticular infections in a paediatric hospital, so as to adapt treatment protocols to the ecology of the bacteria isolated.
Patients and methods |
Prospective descriptive study, including children admitted for acute osteomyelitis or septic arthritis. A series of blood cultures was performed systematically on admission. In case of surgery, local samples were taken for bacteriology. Antibiotherapy was initiated and subsequently adapted to the bacteriological findings.
Results |
One hundred and six children were included. Thirty-five were under (Group 1) and 71 over 3 years of age (Group 2). Ninety-five underwent surgery. Peroperative samples were positive in 61 cases and blood culture in 23. Bacteria were isolated in 22 patients in G1. Extended-spectrum β-lactamase-producing Klebsiella pneumoniae was isolated in five neonates who had passed through intensive care. Staphylococcus aureus was the most frequently isolated bacterium in G2 (n=40), and was methicillin-resistant (MRSA) in six children.
Discussion |
Methicillin-susceptible Staphylococcus aureus was the most frequently isolated microorganism. Other than neonates who had passed through intensive care and the six patients with community-acquired MRSA infection, all isolated bacteria were susceptible to second-generation cephalosporins.
Level of evidence |
II, prospective descriptive prognostic study.
