Respiratory multiplex polymerase chain reaction: An important diagnostic tool in immunocompromised patients

A Diagnostic Multiplex Polymerase Chain Reaction Assay for Ocular Herpetic Infections.

Molecular detection of Pneumocystis jirovecii using polymerase chain reaction in immunocompromised patients with pulmonary disorders in northeast of Iran

Background and Purpose: Pneumocystis pneumonia, caused by Pneumocystis jirovecii, is a fatal disease threatening patients with AIDS or immunosuppression. Assessment of colonization in these patients is of great significance, since it can lead to severe pulmonary disorders. Considering the scarcity of published reports on Pneumocystis jirovecii isolates from patients in Mashhad, Iran, we aimed t...

Impact of Multiplex Polymerase Chain Reaction Testing for Respiratory Pathogen Detection in Pediatric Patients

Polymerase Chain Reaction: a Powerful Diagnostic and Research Tool

To fully understand cellular processes, scientists often examine events at the level of nucleic acids and protein molecules. These studies are complicated by the fact that cells have miniscule amounts of molecules of interest which are too small to be seen. So we require molecular tools to visualize these molecules. Polymerase chain reaction is one such technique widely used in molecular biolog...

Polymerase chain reaction as a diagnostic tool for detecting Leishmania.

Polymerase chain reaction (PCR) has been used to identify a Leishmania parasite in a cutaneous ulcer from a 27-year-old patient infected during travel in Peru. The available classical diagnostic methods could not confirm the diagnosis in a sufficiently short time. Therefore, two sets of oligonucleotides were designed and with both of them fragments of the expected size were obtained. The sequen...
