Background: Candida albicans is the predominant yeast reported from human infection. Non-albicans species have been recently developed as medically vital fungi. Therefore, it essential to detect and identify pathogens at level prescribe appropriate treatment. Methods: This study assessed two complementary methods, including real-time polymerase chain reaction-high resolution melt (PCR-HRM) reac...

among the viruses infecting honey bees, chronic bee paralysis virus (cbpv) is known to induce significant losses in honey bee colonies. cbpv is an unclassified polymorphic single stranded rna virus. using rt-pcr, the virus infections in honey bees can be detected in a rapid and accurate manner. bee samples were collected from 23 provinces of iran, between july-september 2011 and 2012. a total o...

The limitation of polymerase chain reaction (PCR) in diagnosis of lower respiratory tract infections (LRTIs) caused by Streptococcus pneumoniae, Haemophilus influenzae, and Moraxella catarrhalis has been a distinguishing colonization from infection. We assess here the usefulness of real-time quantitative PCR (RQ-PCR) performed on lower respiratory tract samples to overcome this problem. Consecu...

Orientia tsutsugamushi is the causative agent of scrub typhus. For the diagnosis of scrub typhus, we investigated the performances of conventional PCR (C-PCR), nested PCR (N-PCR), and real-time quantitative PCR (Q-PCR) targeting the O. tsutsugamushi-specific 47-kDa gene. To compare the detection sensitivities of the three techniques, we used two template systems that used plasmid DNA (plasmid d...

Tapah fish (Wallago leerii) is a with high economic value in Riau Province. Molecular research on W. leerii very important to do. This study aims determine the molecular characteristics of from Province based Cytochrome b gene. The universal primer used for Polymerase Chain Reaction (PCR) process. PCR result partial gene length 373 bp. Multiple alignments were performed nucleotide sequences riv...

INTRODUCTION This study was performed to compare nested-polymerase chain reaction (PCR) with viral culture as a diagnostic tool for genital herpes simplex virus (HSV) infection in a sexually transmitted infection (STI) clinic in Singapore. METHODS 103 consecutive patients presenting with clinical features suggestive of genital herpes were enrolled in the study. Two swabs were obtained from ea...

BACKGROUND We intend to design and validate a low-cost assay for the detection of hepatitis C virus (HCV) RNA using rapid-cycle RT-PCR. The procedure is performed in a closed system with little risk of contamination allowing PCR and product identification to be performed within one or two hours. METHODS A SYBR Green-based real-time RT-PCR for rapid detection of HCV. Amplicon synthesis was mon...

We developed a rapid thermocycling, real-time detection (also known as real-time PCR) method for the detection of Legionella species directly from clinical specimens. This method uses the LightCycler (Roche Molecular Biochemicals, Indianapolis, Ind.) and requires approximately 1 to 2 h to perform. Both a Legionella genus PCR assay and Legionella pneumophila species-specific PCR assay were desig...

We compared Streptococcus pneumoniae serotype 1 isolates causing disease among children in six geographic regions of the United States to determine genetic relatedness. Genomic fingerprints were determined by repetitive element polymorphism PCR (Rep-PCR). Multilocus sequence type characterization was performed on selected isolates. Four different genomic banding patterns were identified by Rep-...
