is a fastidious microorganism associated with blood culture negative endocarditis. In this study, 40 sera with cross-reactivity between species from patients from Sfax, Tunisia, were serologically tested for Thirteen sera were positive for with IgG titers ≥1:800. Western blot and cross-absorption confirmed the diagnosis of endocarditis in 12 cases and endocarditis in 1 case. These sera were also positive by LightCycler nested PCR amplification for the (7 of 13) and (11of 13) genes. Eleven patients had a definite diagnosis of endocarditis, which represents 9.8% of all endocarditis. Because endocarditis seems to be very common in Tunisia, we suggest that its serology be performed systematically whenever endocarditis is suspected.
