background and objectives: pcr is a sensitive assay and could be used as an accurate diagnostic method for detecting various types of microorganisms' genome in low concentration in biological specimens. the demand for sensitive, rapid, safe and easy detection of pcr products has led researchers to a combination of this method with elisa. materials and methods: conserved sequences were selected ...

Epstein-Barr virus (EBV), a human herpesvirus, affects up to 95% of adults. Diagnosis of acute EBV infection can be challenging and often relies on the serologic antibody pattern to 3 distinct antigens, most often determined by indirect fluorescent antibody (IFA), enzyme-linked immunosorbent assays (ELISAs), and, more recently, multiplex assays. We compared a multiplex assay for the simultaneou...

Validation studies are a crucial requirement before implementation of new genetic typing systems for clinical diagnostics or forensic identity. Two different fluorescence-based multiplex DNA profiling systems composed of amelogenin, HumD21S11 and HumFGA (referred to as multiplex 1A), and HumD3S1358, HumD21S11 and HumFGA (multiplex 1B) have been evaluated for use in forensic identification using...

BACKGROUND/AIM Malaria is a major public health problem, especially in the Southeast Asia region, caused by 5 species of Plasmodium (P. falciparum, P. vivax, P. malariae, P. ovale, and P. knowlesi). The aim of this study was to compare parasite species identification methods using the new multiplex polymerase chain reaction (PCR) against nested PCR and microscopy. MATERIALS AND METHODS Blood ...

Objectives Emergence of methicillin resistant Staphylococcus aureus (MRSA) is a major medical problem of current era. These bacteria are resistant to most drugs and rapid diagnosis can provide a clear guideline to clinicians. They possess specific virulence factors and relevant information can be very useful. We designed this study to develop multiplex PCRs to provide rapid information. Metho...

Multiple infections by pathogens are currently the most serious problems in pig herds. Clinically, accurate diagnosis is difficult due to similarity of the symptoms of porcine pseudorabies virus (PRV), porcine parvovirus (PPV), and porcine circovirus type 2 (PCV2). A multiplex polymerase chain reaction (multiplex-PCR) was developed and optimized for the simultaneous detection of the three DNA v...

BACKGROUND A cost-effective, accurate and rapid simultaneous multiplex assay is required for testing and diagnoses of conventional and emerging viruses in clinical virology laboratories. We developed and optimized a dual priming oligonucleotide (DPO) multiplex PCR assay for detecting influenza viruses including seasonal H1N1, 2009 pandemic H1N1, H3N2, influenza B and H5N1. METHODS The optimiz...

A general analytical description of the equilibrium and reaction kinetics of DNA multiplex hybridization has been developed. In this approach, multiplex hybridization is considered to be a competitive multichannel reaction process: a system wherein many species can react both specifically and nonspecifically with one another. General equations are presented that can consider equilibrium and kin...

The integration of information from multiple databases has been an enduring subject of research for almost 20 years, and many di erent solutions have been attempted or proposed. Missing from this research has been a uniform framework. Usually, each solution develops its own ad-hoc framework, designed to address the particular aspects of the problem that are being attacked and the particular met...
