Osteomyelitis is commonly caused by Staphylococcus aureus. Both erythromycin and
curcumin can suppress S. aureus growth, but their roles in osteomyelitis are
barely studied. We aim to explore the activities of erythromycin and curcumin
against chronical osteomyelitis induced by methicillin-resistant S. aureus
(MRSA). Chronicle implant-induced osteomyelitis was established by MRSA infection
in male Wistar rats. Four weeks after bacterial inoculation, rats received no
treatment, erythromycin monotherapy, curcumin monotherapy, or erythromycin plus
curcumin twice daily for 2 weeks. Bacterial levels, bone infection status,
inflammatory signals and side effects were evaluated. Rats tolerated all
treatments well, with no death or side effects such as, diarrhea and weight loss.
Two days after treatment completion, erythromycin monotherapy did not suppress
bacterial growth and had no effect in bone infection, although it reduced serum
pro-inflammatory cytokines tumor necrosis factor (TNF)-? and interleukin (IL)-6.
Curcumin monotherapy slightly suppressed bacterial growth, alleviated bone
infection and reduced TNF-? and IL-6. Erythromycin and curcumin combined
treatment markedly suppressed bacterial growth, substantially alleviated bone
infection and reduced TNF-? and IL-6. Combination of erythromycin and curcumin
lead a much stronger efficiency against MRSA induced osteomyelitis in rats than
monotherapy. Our study suggests that erythromycin and curcumin could be a new
combination for treating MRSA induced osteomyelitis.
