Background and Purpose: The clinical and epidemiologic features of Kawasaki disease (KD) suggest an infectious etiology however, the agent(s) remain unknown. Our purpose was to isolate the causative bacterial gene from peripheral blood leukocytes of patients with acute KD, by Universal polymerase chain reaction (UPCR), in Tehran Children’s Medical Center. Materials and Methods: Universal p...
We describe a rapid, reproducible, and sensitive method for detection and quantification of archaea in naturally occurring microbial communities. A domain-specific PCR primer set and a domain-specific fluorogenic probe having strong and weak selectivity, respectively, for archaeal rRNA genes (rDNAs) were designed. A universal PCR primer set and a universal fluorogenic probe for both bacterial a...
The aim of this study was to assess potential candidate gene regions and corresponding universal primer pairs as secondary DNA barcodes for the fungal kingdom, additional to ITS rDNA as primary barcode. Amplification efficiencies of 14 (partially) universal primer pairs targeting eight genetic markers were tested across > 1 500 species (1 931 strains or specimens) and the outcomes of almost twe...
We attempted to develop a PCR-based marker that detects various segments of rye chromosome incorporated into wheat. We designed three sets of PCR primers based on the nucleotide sequence data of a rye repetitive sequence previously reported. One of the primer sets amplified a clear ca. 1.4 kb fragment in a rye cultivar but not in any form of wheat, diploid, tetraploid or hexaploid. We used this...
BACKGROUND MNAzymes (nucleic acid enzymes formed from multiple partial enzymes) can be linked to PCR to provide a highly specific method for target detection and quantification. We investigated the feasibility of multiplexing MNAzyme quantitative PCR (qPCR) methods. METHODS We combined MNAzyme components with PCR primers and standard qPCR reagents to perform MNAzyme qPCR and reverse-transcrip...
abstract- desert truffles are hypogeous ascomyceteous ectomycorrhizal fungi, occurring in arid and semi-arid ecosystems. a pcr-based method was developed for the identification of 3 major desert truffles of iran: terfezia claveryi, tirmania pinoyi and tirmania nivea based on internal transcribed spacers of rdna. two specific pcr primers were designed for t. claveryi, 4 for t. pinoyi, and 2 for ...
OBJECTIVE Early and accurate diagnosis of bacterial meningitis is of critical concern. Optimum and rapid laboratory facilities are not routinely available for detecting the etiologic agents of meningitis. The objective of this study was to compare polymerase chain reaction (PCR) assay with culture for detection of bacteria in central nervous system (CNS) samples from patients suspected to have ...
