Background: Suppurative arthritis induced by Scedosporium apiospermum (S. apiospermum) or Mycobacterium fortuitum (MF) was rare, and even more so when caused by a mixed infection of the two. In this paper, we report the rare case of suppurative arthritis induced by S. apiospermum and MF.
Methods: A 46-year-old patient whose left knee was accidentally injured by a rotary tiller. His left knee joint was clearly swollen although debridement and suturing had been performed twice at a local hospital. Bacterial culture result was MF and S. apiospermum after admission. Definitive therapy (debridement combined with treatment using three antibiotics) was initiated.
Results: Although the fungus reappeared when he tried to discontinue the drug, after the third debridement combined with treatment using three antibiotics for 8 months, the infection was controlled and did not recur.
Conclusions: This demonstrates that early bacteriological examination is essential. Treatment of fungus generally requires a long course. However, course of medication should be related to the patient's specific conditions and the implementation of the operation.
