Abstract
The results of a Dot immunobinding assay (Dot Iba) for the detection of mycobacterial antigen in the cerebrospinal fluid (CSF) of 45 patients with tuberculous meningitis (TBM) were compared with the results of a polymerase chain reaction (PCR) for the detection of Mycobacterium tuberculosis. In eight patients with culture proven TBM, Dot-lba gave positive results, while PCR yielded positive results only in six patients. The overall sensitivities of Dot-lba and PCR in 37 patients with culture negative (probable) TBM were 75.67% and 40.5% respectively. Dot-lba, in contrast to PCR is a rapid and relatively easier method. More importantly, Dot-lba is suitable for the routine application for the laboratory diagnosis of TBM and therefore best suited to laboratories in the developing world. (C) 2002 Elsevier Science Inc.
