Quantitative detection of Streptococcus pneumoniae in nasopharyngeal secretions by real-time PCR.
Streptococcus pneumoniae is an important cause of community-acquired pneumonia. However, in this setting the diagnostic sensitivity of blood cultures is below 30%. Since during such infections changes in the amounts of S. pneumoniae may also occur in the upper respiratory tract, quantification of these bacteria in nasopharnygeal secretions (NPSs) may offer a suitable diagnostic approach. Real-t...
متن کاملQuantitative detection of Streptococcus pneumoniae, Haemophilus influenzae, and Moraxella catarrhalis in lower respiratory tract samples by real-time PCR.
The limitation of polymerase chain reaction (PCR) in diagnosis of lower respiratory tract infections (LRTIs) caused by Streptococcus pneumoniae, Haemophilus influenzae, and Moraxella catarrhalis has been a distinguishing colonization from infection. We assess here the usefulness of real-time quantitative PCR (RQ-PCR) performed on lower respiratory tract samples to overcome this problem. Consecu...
متن کاملMolecular detection of Mycoplasma pneumoniae by quantitative real-time PCR in patients with community acquired pneumonia
BACKGROUND & OBJECTIVES Mycoplasma pneumoniae is the most important and common cause of community-acquired pneumonia (CAP). The conventional detection methods (culture and serology) lack sensitivity. PCR offers a better approach for rapid detection but is prone to carry over contamination during manipulation of amplification products. Quantitative real-time PCR (qRT-PCR) method offers an attrac...
متن کاملQuantitative detection of chicken meat routine mislabeling in emulsion type sausages and burgers by SYBR green real time PCR assay
ABSTRACT- Today, the authenticity of meat products with less costly and desirable species has increased. Therefore and considering religious, economicalor public health concerns, proper actions should be taken to prevent such frauds. In this study, real time PCR assay was applied for rapid, sensitive and specific identification and quantification of chicken tissue in meat products. Specific pri...
متن کاملQuantitative detection of respiratory Chlamydia pneumoniae infection by real-time PCR.
Real-time PCR was evaluated as a quantitative diagnostic method for Chlamydia pneumoniae infection using different respiratory samples. Real-time PCR had efficiency equal to or better than that of nested touchdown PCR. This study confirmed sputum as the best sampling material to detect an ongoing C. pneumoniae infection.
