background and objectives: hiv-1 and hcv infections are life threatening problems in patients who receive blood products. serological methods have proven useful in detecting these infections, but there are setbacks that make it challenging to detect these infectious agents. by the advent of nucleic acid testing (nat) methods, especially in multiplex format, more precise detection is possible. m...

Bacterial meningitis infection is a leading global health concern for which rapid and accurate diagnosis is essential to reduce associated morbidity and mortality. Loop-mediated isothermal amplification (LAMP) offers an effective low-cost diagnostic approach; however, multiplex LAMP is difficult to achieve, limiting its application. We have developed novel real-time multiplex LAMP technology, T...

A multiplex real-time PCR assay was developed using molecular beacons for the detection of Vibrio cholerae by targeting four important virulence and regulatory genes. The specificity and sensitivity of this assay, when tested with pure culture and spiked environmental water samples, were high, surpassing those of currently published PCR assays for the detection of this organism.

ABSTRACT A real-time fluorescent polymerase chain reaction (PCR) detection method for the sudden oak death pathogen Phytophthora ramorum was developed based on mitochondrial DNA sequence with an ABI Prism 7700 (TaqMan) Sequence Detection System. Primers and probes were also developed for detecting P. pseudosyringae, a newly described species that causes symptoms similar to P. ramorum on certain...

BACKGROUND Shigella species are among the common causes of bacterial diarrhoeal diseases. Traditional detection methods are time-consuming resulting in delay in treatment and control of Shigella infections thus there is a need to develop molecular methods for rapid and simultaneous detection of Shigella spp. In this study a rapid multiplex PCR were developed for simultaneous detection of three ...

Two new primer sets of a 766- and a 344-bp fragment were introduced into the conventional Bruce-ladder PCR assay. This novel multiplex PCR assay rapidly and concisely discriminates Brucella canis and Brucella microti from Brucella suis strains and also may differentiate all of the 10 Brucella species.

Multiplex protein quantification has been constrained by issues of assay specificity, sensitivity and throughput. This research presents a novel approach that overcomes these limitations using antibody-oligonucleotide conjugates for immuno-polymerase chain reaction (immuno-PCR) or proximity ligation, coupled with competitive PCR and MALDI-TOF mass spectrometry. Employing these combinations of t...
