DNA-based methodology for the identification and detection of specific bacteria in dental plaque offers advantages over culturing techniques. One drawback of current molecular techniques like real-time quantitative polymerase chain reaction (RT-QPCR) is that they are not able to distinguish between

The persistence of naturally occurring campylobacteria in aerobic compost constructed of manure from beef cattle that were administered chlortetracycline and sulfamethazine (AS700) or from cattle not administered antibiotics (control) was examined. Although there were no differences in population sizes of

The polymerase chain reaction (PCR) can confirm the presence of bacteria, but it is unable to differentiate between live and dead bacteria. Although ethidium monoazide (EMA)- and propidium monoazide (PMA)-based PCR have been evaluated, a quantity of ≥ 10(3)cells/ml dead

A method was developed for discriminating damaged viruses or naked viral RNA from intact viruses by ethidium monoazide (EMA) treatment before RT-PCR. The applied EMA treatment consisted of three steps: (1) EMA dose, (2) exposure to light, and (3) additional
