Summary of "Development and evaluation of a real-time polymerase chain reaction for fast diagnosis of sporotrichosis caused by Sporothrix globosa."

Sporothrix globosa is an important clinical pathogen in the Sporothrix complex, which is causing sporotrichosis. S. globosa is distributed worldwide, especially in Asia. The transmission medium of S. globosa is mainly contaminated soil or decaying vegetation, and the infection usually caused by transcutaneous trauma, through which the fungal conidia or yeast cells enter the host. Although the clinical manifestations of sporotrichosis caused by S. globosa is always benign, there have been several outbreaks worldwide. In this study, we established a novel real-time polymerase chain reaction (PCR) method based on the internal transcribed spacer (ITS) sequence for the identification of S. globosa. The assay was further evaluated by clinical specimens obtained from patients of sporotrichosis. The sensitivity and specificity of the real-time PCR method was both 100%. The detection limit was 10 fg. The positive detection rate for 30 clinical specimens, which were confirmed infected by S. globosa, was 100%. The real-time PCR method established in this paper is a rapid, sensitive and specific method for the identification of S. globosa. It can detect S. globosa in clinical specimen from patients with sporotrichosis, which is helpful for fast clinical diagnosis.

Medical and Biotech [MESH] Definitions

Methods used for detecting the amplified DNA products from the polymerase chain reaction as they accumulate instead of at the end of the reaction.

Methods for using more than one primer set in a polymerase chain reaction to amplify more than one segment of the target DNA sequence in a single reaction.

A heat stable DNA-DIRECTED DNA POLYMERASE from the bacteria Thermus aquaticus. It is widely used for the amplification of genes through the process of POLYMERASE CHAIN REACTION. EC 2.7.7.-.

A technique that labels specific sequences in whole chromosomes by in situ DNA chain elongation or PCR (polymerase chain reaction).

In vitro method for producing large amounts of specific DNA or RNA fragments of defined length and sequence from small amounts of short oligonucleotide flanking sequences (primers). The essential steps include thermal denaturation of the double-stranded target molecules, annealing of the primers to their complementary sequences, and extension of the annealed primers by enzymatic synthesis with DNA polymerase. The reaction is efficient, specific, and extremely sensitive. Uses for the reaction include disease diagnosis, detection of difficult-to-isolate pathogens, mutation analysis, genetic testing, DNA sequencing, and analyzing evolutionary relationships.
