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...

Micro-Polymerase Chain Reaction Chip Construction for Fluorescence Detection Test

This paper proposes the optimal structure of a Printed Circuit Boardbased micro-PCR chip constructed on a PCB substrate using commercial adhesive tapes and plastic films. The proposed micro-PCR chip was composed of four layers. In a previous experiment, the chip had been made with a green PCB, yielding an unwanted reflection that prevented accurate analysis. In this study, the solder mask of th...

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...

Tracing of Helicobacter Pylori in Patients of Otitis Media with Effusion by Polymerase Chain Reaction

Otitis media with effusion (OME) is one of the most common causes of hearing loss (HL) in children. It has been reported that several factors such as eustachian tube dysfunction, insufficiencies in the aeration of the mastoid cells, allergies, immunity, and infections play an important role in the etiology of the disease. Little is known about the role of Helicobacter pylori (H. pylori) in extr...
