Conclusion
The molecular panel presented offers the advantage of an easy, reliable, and cost-effective system when compared to other molecular detection methods. However, further evaluation is needed. Our assay holds promising for more rapid pathogens related in clinical sepsis.
Methods
Primers for amplification of enterobacteriaceae, IC, and16S rDNA were designed, and then PCR was performed. Minimal analytical sensitivity was determined by cloning and colony PCR, and specificity was tested on the basis of their respective standard strains. This study is a cross-sectional Model.
Objective
Sepsis is a systemic inflammatory response associated with high mortality rates in the clinical setting. A multiplex endpoint polymerase chain reaction (PCR) based assay for rapid detection of enterobacteriaceae involved in septicemia, which included Internal Control (IC) and 16S rDNA, is presented here. To develop a panel of primers for DNA fragments of 16S rDNA, enterobacteriaceae, IC, and evaluate analytical sensitivity and specificity of the test. Materials and
Results
Our results showed the rpoB gene as the most promising target for detection of enterobacteriaceae by PCR amplification. Specificity and sensitivity of endpoint PCR were 100%, 100%, and 100%, and 10, 1, and 100 copies/reaction for enterobacteriaceae, IC, and 16S rDNA, respectively.
