Here we report the design and evaluation of a loop-mediated isothermal amplification (LAMP) assay for detecting Acinetobacter baumannii DNA based on the 16S-23S rRNA intergenic spacer (ITS) sequence. The results showed that target DNA was amplified and visualized within 30min and with a detection limit 100-fold greater than PCR.
Compared to the composite gold standard cytotoxin B assay and toxigenic culture, the loop-mediated isothermal amplification (LAMP) test for Clostridium difficile had a sensitivity and specificity of 98%, positive predictive value of 92%, and negative predictive value of >99%. A one-hour turnaround time for the LAMP test provides rapid diagnosis and cost savings.
Molecular diagnostic measurements are currently underpinned by the polymerase chain reaction (PCR). There are also a number of alternative nucleic acid amplification technologies, which unlike PCR, work at a single temperature. These 'isothermal' methods, reportedly offer potential advantages over PCR such as simplicity, speed and resistance to inhibitors and could also be used for quantitative...
A reverse transcription loop-mediated isothermal amplification (RT-LAMP) assay targeting the nucleocapsid phosphoprotein gene of infectious bronchitis virus (IBV) was developed. The detection limits for the IBV RT-LAMP assay were 10(1) 50% egg infection dose (EID(50)) per 50 microl of titrated viruses and no cross-reaction of IBV RT-LAMP was found when tested with other viruses including Newcas...
