Species-specific detection of Candida tropicalis using evolutionary conserved intein DNA sequences.

Development of molecular markers for specific detection of microbial pathogens using real-time polymerase chain reaction (PCR) is an appealing and challenging technique. A real-time PCR is an emerging technology frequently used to detect the aetiologic agents. In recent times, designing species-specific primers for pathogen detection is gaining momentum. The method offers rapid, accurate and cost-effective strategy to identify the target, thus providing sufficient time to instigate appropriate chemotherapy. The study highlights the use of intein DNA sequence as molecular markers for species-specific identification of Candida tropicalis. The study also offers a prototype model for developing multifaceted PCR assays using intein DNA sequences, and provides a developmental starting point for point-of-care testing in near future.
