Amplification of Coccidioidal DNA in Clinical Specimens by PCR

Amplification of coccidioidal DNA in clinical specimens by PCR.

Coccidioides DNA was amplified from serum by a PCR using coccidioid-specific primers. A 239-bp product was visualized when 10 fg of exogenous coccidioidal DNA was subjected to amplification. This product was demonstrated in some human and mouse sera prior to the detection of coccidioidal antibodies.

Amplification of Coccidioidal DNA in Clinical Specimens by PCR

Recombinant DNA sequences generated by PCR amplification.

The polymerase chain reaction (PCR) has greatly enhanced the field of molecular biology by making numerous regions of the genome (coding and noncoding), in both extant and extinct taxa, accessible for detailed analysis. PCR is especially well suited for applications in systematic biology because conserved regions that flank variable portions of the genome can be used as primer sites for the amp...

Detection of cytomegalovirus DNA in human specimens by LightCycler PCR.

Detection of human cytomegalovirus (CMV) DNA in clinical specimens is considered a cornerstone in the diagnosis of CMV disease. The aim of this study was to evaluate a newly designed LightCycler-based quantitative CMV PCR. Specimens of human origin (n = 200) were tested using the LightCycler PCR, the quantitative COBAS AMPLICOR CMV MONITOR (CACM) assay, and a qualitative in-house PCR assay for ...

PCR Typing of Trichophyton Rubrum Isolates by Specific Amplification of Subrepeat Elements in Ribosomal DNA Nontranscribed Spacer

Background: Trichophyton rubrum (T. rubrum) is the most common cause of dermatophytosis of skin and nail tissue. Strain identification in Trichophyton rubrum is important for identification of strain-related differences in infectivity potential or transmissibility and epidemiological studies. PCR typing could determine whether the original isolate is responsible for re-infection or a new strain...
