Polymerase Chain Reaction for the Diagnosis of Tuberculosis

Dear Editor-in-Chief We read with interest the study by Khazaei et al. (1) in which the authors have nicely concluded that PCR is more sensitive test than Ziehl-Neelsen staining and histo-pathological examination for the diagnosis of tuberculosis (TB). They have rightly pointed to use PCR, selectively, in acidfast bacilli negative paucibacillary forms of TB. However, we intend to highlight few...

Development of New Modified Simple Polymerase Chain Reaction and Real-time Polymerase Chain Reaction for the Identification of Iranian Brucella abortus Strains

Brucellosis is primarily a worldwide zoonotic disease caused by Brucella species. The genus Brucella contains highly infectious species that are classified as biological threat agents. In this regard, the identification of Brucella can be a time-consuming and labor-intensive process posing a real risk of laboratory-acquired infection to the laboratory staff. This stud...

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 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...
