Acute bacterial meningitis is a medical emergency, and delays in initiating effective antimicrobial therapy result in increased morbidity and mortality. Culture-based methods, thus far considered the "gold standard" for identifying bacterial microorganisms, require 24 to 48 h to provide a diagnosis. In addition, antimicrobial therapy is often started prior to clinical sample collection, thereby...

BACKGROUND AND OBJECTIVES In the last few years molecular methods have allowed the identification of leukemia-associated genetic lesions, which may represent the most accurate predictors of clinical outcome. These considerations strengthen the need for rapid identification of the abnormalities. Our aim was to demonstrate whether a modified multiplex reverse transcription polymerase chain reacti...

BACKGROUND In this study, we evaluated the analytical performance and clinical potential of a one-step multiplex real-time PCR assay for the simultaneous detection of 14 types of respiratory viruses using the AdvanSure RV real-time PCR Kit (LG Life Sciences, Korea). METHODS Three hundred and twenty clinical specimens were tested with the AdvanSure RV real-time PCR Kit and conventional multipl...

INTRODUCTION Accurate etiological diagnosis of meningitis is important, but difficult in resource-limited settings due to prior administration of antibiotics and lack of viral diagnostics. We aimed to develop and validate 2 real-time multiplex PCR (RT-PCR) assays for the detection of common causes of community-acquired bacterial and viral meningitis in South African children. METHODS We devel...

background and aims: infectious bronchitis virus (ibv) causes an acute, highly contagious respiratory and kidney disease of chickens which results in significant economic losses in commercial broilers, layers and breeders. rapid identification of ibv serotypes involved in respiratory complex is a problem in the differential diagnosis. materials and methods: in this study, a single and multiplex...

PURPOSE EML4-ALK is a lung cancer oncogene, and ALK inhibitors show marked therapeutic efficacy for tumors harboring this fusion gene. It remains unsettled, however, how the fusion gene should be detected in specimens other than formalin-fixed, paraffin-embedded tissue. We here tested whether reverse transcription PCR (RT-PCR)-based detection of EML4-ALK is a sensitive and reliable approach. ...

Abstract A multiplex reverse transcription polymerase chain reaction (multiplex RT-PCR) assay was developed to enable the simultaneous detection and differentiation of four viruses that infect passion fruit, citrus-associated rhabdovirus (CiaRV), East Asian Passiflora virus (EAPV), latent (PLV), Telosma mosaic (TeMV). The optimized parameters included primer concentration, annealing temperature...

A novel multitarget real-time PCR (RT-PCR) assay for the rapid identification of Bordetella pertussis, B. parapertussis, and B. holmesii was developed using multicopy insertion sequences (ISs) in combination with the pertussis toxin subunit S1 (ptxS1) singleplex assay. The RT-PCR targets for the multiplex assay include IS481, commonly found in B. pertussis and B. holmesii; IS1001 of B. parapert...

AIMS To develop a highly sensitive and rapid protocol for simultaneous detection and differentiation of Tobacco mosaic virus (TMV) and Tomato mosaic virus (ToMV) in pepper and tomato. In this study, we use the multiplex PCR technique to detect dual infection of these two viruses. METHODS AND RESULTS A multiplex RT-PCR method consisting of one-tube reaction with two primer pairs targeted to re...
