title: Teichoic acid antibody test: its use in patients with coagulase-positive staphylococcal bacteremia.
abstract: We have studied the occurrence and specificity of teichoic acid antibodies (TAAs), measured by double diffusion in agar, in 114 patients with bacteremia of whom 47 had coagulase-positive staphylococcal bacteremia. A total of 30% of the 47 patients with coagulase-positive staphylococcal bacteremia had a TAA titer of 1:8 or more, and an additional 30% had a titer of 1:2 or 1:4. High TAA titers were most often connected with coagulase-positive staphylococcal endocarditis, osteomyelitis, and deep wound infections. None of the six coagulase-negative patients with staphylococcal bacteremia nor any of the 92 controls had titers exceeding 1:1. A total of 10% of the other patients with bacteremia showed positive results on the TAA test at low titer levels. Compared to the antistaphylolysin value, the TAA test was about equally specific but more sensitive.
