Abstract
The usual diagnosis of life-threatening human brain bacterial meningitis are expensive, time consuming or non-confirmatory. A quick PCR based diagnosis of meningitis in cerebrospinal fluids (CSF) using specific primers of virulent Omp85 gene of Neisseria meningitidis can detect as low as 1.0 ng of genomic DNA (G-DNA) in 80 min for confirmation of bacterial meningitis caused by N. meningitidis infection. The 257 bp amplicon of Omp85 gene does not show homology with other suspected pathogens in CSF and can be used as a specific genetic marker for diagnosis of the disease.
