title: Rapid identification of Burkholderia pseudomallei in blood culture supernatants by a coagglutination assay.
abstract: In total, 309 blood culture supernatants were tested for the presence of Burkholderia pseudomallei antigen using an in-house coagglutination test prepared by sensitising Cowan I staphylococcal cells with B. pseudomallei polyclonal antiserum. The coagglutination test gave a sensitivity, specificity, positive predictive value and negative predictive value of 100% in comparison with blood culture. A subset of 102 supernatants was also tested for B. pseudomallei antigen using a monoclonal antibody-based latex agglutination test. The sensitivity, specificity, positive predictive value and negative predictive values of this test were 100%, 90%, 75% and 100%, respectively.
