REASONS FOR PERFORMING STUDY The influence of synovial fluid culture on short- and long-term prognosis of cases with septic synovitis requires study. HYPOTHESES Horses with a positive bacterial culture from septic synovial fluid are less likely to survive or return to successful athletic function than those with a negative bacterial culture from septic synovial fluid. METHODS Records of mat...
