Amplification of Coccidioidal DNA in Clinical Specimens by PCR

RAPID DETECTION OF MYCOBACTERIUM TUBERCULOSIS IN CLINICAL SPECIMENS BY POLYMERASE CHAIN REACTION

We investigated the use of DNA amplification by polymerase chain reaction (peR) for detection of Mycobacterium tuberculosis in 300 patients who were suspected of having pulmonary tuberculosis and compared the results with culture results which were performed in parallel with PCR. Two-thirds of each sample was processed for smear and culture by standard methods and one-third was prepared fo...

Effect of Lowering PCR Reaction Volumes and Increasing the Speed of DNA Amplification on the Sensitivity of PCR

ABSTRACT Recently, PCR is being reported more frequently with satisfactory results on the diagnosis of clinical infections. Widespread availability of PCR promises a sensitive and specific alternative, to traditional methods, but these benefits must be balanced against cost. Protocols using small volumes have described where the reaction taken place in capillary tubes, and small volumes work...

Survey on the genital Mycoplasmosis by multiplex PCR

Mycoplasmas hominis, Mycoplasmas genitalium and Ureaplasma urealyticum are associated with infections of the genitourinary tract, reproductive failure, and neonatal morbidity and mortality. A multiplex PCR was developed for simultaneously detection of these Mycoplasmas species in a single amplification reaction. The total number of 104 samples was collected from 104 women’s genital specimens wi...

DNA amplification for the diagnosis of cat-scratch disease in small-quantity clinical specimens.

Diagnosis of cat-scratch disease (CSD) by polymerase chain reaction (PCR) of lymph node fineneedle aspiration (FNA) and primary lesion specimens can be difficult owing to the minute amount of available material. A PCR assay specifically suited to test these specimens was developed. First, small-quantity (10 microL) samples were prepared from 17 CSD-positive and 16 CSD-negative specimens, and DN...
