The diagnosis of tuberculous meningitis (TBM) remains a complex issue because the most widely used conventional diagnostic tools, such as culture and PCR assay for cerebrospinal fluid (CSF) samples, are unable to rapidly detect Mycobacterium tuberculosis with sufficient sensitivity in the acute phase of TBM. Based on TaqMan PCR, we designed a novel technique consisting of an internally controll...

A real-time PCR assay was developed for rapid detection of eubacterial 16S ribosomal DNA in platelet concentrates. The sensitivity of this assay can be hampered by contaminating DNA in the PCR reagents. Digestion of the PCR reagents with Sau3AI prior to PCR amplification was effective in eliminating this contaminating DNA without affecting the sensitivity of the assay.

streptococcus agalactiae is acommensalorganism, but it may cause infection in susceptible hosts. the aim of this study was to evaluate pcr assay compared with conventional culture method for direct detection of streptococcus agalactiae . total of 203 paired low vaginal swabs were collected from women at 35-37 weeks of pregnancy from june 2013 through february 2014 for detection of streptococcus...
