Background:
The Achilles heel in osteomyelitis is that bacteria, primarily Staphylococcus aureus, grow as a biofilm in the bone lesions.
Materials And Methods:
In the present study, we explored the serum level of specific antibodies to S. aurues biofilm in porcine models of osteomyelitis.
Results:
Significantly increased levels of antibodies towards the specific biofilm antigen SA0688 were measured in serum from pigs with S. aureus-associated acute and chronic osteomyelitis 5-7 and 10-14 days after inoculation, respectively. Simultaneously with raised antibody levels, an increase in serum interleukin 6 (IL 6) levels was also seen.
Conclusion:
The observed biofilm-specific antibody response represents a T-helper cell 17 (Th17) response and potentially a T-helper cell 1 (Th1) response. This is in agreement with previous studies in mice and rabbits speculating that S. aureus induces a Th1- and Th17-biased adaptive immune response, instead of a protective Th2 response, in order to evade the immune system, resulting in a chronic infection.
