Evaluation of Nested Polymerase Chain Reaction for Detecting Myocobacterial DNA in Pleural Fluid

Evaluation of the polymerase chain reaction method for detection of Streptococcus pneumoniae DNA in pleural fluid samples.

STUDY OBJECTIVE Streptococcus pneumoniae is the most frequent causative agent of community-acquired pneumonia (CAP); however, an etiologic diagnosis by traditional techniques can be accomplished in only a small percentage of patients with CAP. Pleural fluid is present in approximately 40% of patients with CAP; therefore, we hypothesized that detection of S pneumoniae DNA in pleural fluid by pol...

Detection Of Toxoplasma Gondii and Human Cytomegalovirus DNA in Blood from Transplant Recipients Using Multiplex Nested Polymerase Chain Reaction

Evidences from many studies suggested a polymerase chain reaction (PCR) as a valuable method for diagnosing infectious disease in the transplant recipients. We used this method for detection of Toxoplasma, gondii and human cytomegalovirus in blood specimens from patients after bone marrow or kidney transplantation. DNA of both infectious agents were detected using two separate sets of nested pr...

SPECIFIC AMPLIFICATION OF ASPERGILLUS FUMlGATUS DNA BY POLYMERASE CHAIN REACTION

Invasive aspergillosis (1 is a life-threatening condition in immunocompromised patients. An early diagnosis is of great importance because early treatment may resolve this potentially fatal infection. Recently, the polymerase chain reaction (PCR) has been used successfully in detecting specific DNA of several pathogen. In this study, nested PCR was used to detect DNA specific for A!.pergiflus s...

Detection of Mycobacterial DNA Using Nested Polymerase Chain Reaction of Pleural Biopsy Specimens: Compared to Pathologic Findings

BACKGROUND Although there are many methods including AFB smear and culture, and the analysis of pleural fluid in the etiological diagnosis of pleural effusion, it is sometimes difficult to confirm a diagnosis especially in cases of incomplete pleural biopsies. Moreover, the high incidence of tuberculous pleuritis in young people caused confusion in the differential diagnosis of pleural effusion...
