Περίληψη:
Rapid, accurate and inexpensive diagnosis of bacterial meningitis is
critical for patient management. This study describes the development
and evaluation of a multiplex PCR assay for the detection of Neisseria
meningitidis, Streptococcus pneumoniae and Haemophilus influenzae type
b, which globally account for 90% of cases of bacterial meningitis. The
single-tube assay, based on the ctrA, ply and bex targets, respectively,
enabled detection of 5-10 pg DNA. When the assay was tested with
clinical samples (n = 425), its sensitivity for the three targets was
93.9%, 92.3% and 88%, respectively, while the overall specificity and
positive predictive value of the assay was 100%. The negative
predictive value was 99.1-99.5%. The methodology permits rapid and
accurate detection of the three main pathogens that cause bacterial
meningitis.
