Detection of Nocardia Asteroides Complex in Clinical Isolates by Real-Time Polymerase Chain Reaction

Background and Aims: Nocardia asteroides complex is the most common cause of infectious diseases due to nocardiosis. Interspecies differentiation of Nocardia genera is essential for prognosis and timely proper treatment, as well as for epidemiological studies. Since each genus has its own antibiotic resistance, precise careful diagnosis is of prime importance. As compared to biochemical and phe...

Quantitative Real-time Polymerase Chain Reaction (qRT-PCR). Fatemeh Mehrpooyan*

Real-time polymerase chain reaction.

Real-time PCR is the state-of-the-art technique to quantify nucleic acids for mutation detection, genotyping and chimerism analysis. Since its development in the 1990s, many different assay formats have been developed and the number of real-time PCR machines of different design is continuously increasing. This review provides a survey of the instruments and assay formats available and discusses...

Detection and quantification in real-time polymerase chain reaction

The estimation of the concentration of an infectious agent in the environment is a key step to trigger an alert when there is a biological threat. This concentration can be obtained trough a quantitative polymerase chain reaction (qPCR). Nevertheless, standard real-time procedure do not address detection delay which is a main concern in alert triggering. Therefore, we propose a method based on ...

Detection of castor contamination by real-time polymerase chain reaction.

Due to the potential for intentional contamination of food with crude preparations containing ricin, a real-time PCR method was developed for the detection of castor plant material in ground beef. One primer pair was identified and confirmed to be castor-specific and efficient for amplification of ricin in DNA extracts from castor or beef matrices. Of three different DNA extraction protocols co...
