background legionellaceae contains legionella genus with over 52 species and 64 serogroups. it is one of the most important causes of respiratory disease in human. more than 30% of hospital-acquired pneumonia is caused by legionella. ventilator-associated pneumonia (vap) is an infection acquired in hospital wards, particularly in intensive care unit (icu). this disease approximately affects 9% ...

Avian hepatitis E virus (HEV) isolates could be separated into at least three genotypes. In this study, the development of the first duplex TaqMan real-time reverse transcription-PCR (RT-PCR) assay for detection and quantification of avian HEV is presented. Primers and probes binding within relatively conserved open reading frame 3 (ORF3) were designed. Tenfold dilution series of in vitro-trans...

Maize chlorotic mottle virus (MCMV) infects maize plants and causes significant losses in corn production worldwide. In this study, a real-time TaqMan RTPCR assay for efficient detection of MCMV was described. A pair of primers amplifying a 131-bp DNA fragment and a TaqMan probe was designed targeting the novel molecular marker based on MCMV genome analysis sequences. The assay designed was hig...

We describe a simple method for detection of Plasmodium vivax and Plasmodium falciparum infection in anophelines using a triplex TaqMan real-time polymerase chain reaction (PCR) assay (18S rRNA). We tested the assay on Anopheles darlingi and Anopheles stephensi colony mosquitoes fed with Plasmodium-infected blood meals and in duplicate on field collected An. darlingi. We compared the real-time ...

background and objectives: pneumonia with acinetobacter baumannii has a major therapeutic problem in health care settings. decision to initiate correct antibiotic therapy requires rapid identification and quantification of organism. the aim of this study was to develop a rapid and sensitive method for direct detection of a. baumannii from respiratory specimens. materials and methods : a taqman ...

We developed a rapid and sensitive method for the routine detection of all members of the enterovirus genus in different clinical specimens by using real-time TaqMan quantitative PCR. Multiple primer and probe sets were selected in the highly conserved 5'-untranslated region of the enterovirus genome. Our assay detected all 60 different enterovirus species tested, whereas no reactivity was obse...

BACKGROUND DNA genotyping with mutation-specific TaqMan(R) probes (Applied Biosystems) is broadly used in detection of single-nucleotide polymorphisms but is less so for somatic mutations because of its limited selectivity for low-level mutations. We recently described coamplification at lower denaturation temperature-PCR (COLD-PCR), a method that amplifies minority alleles selectively from mix...

Neisseria meningitidis (Nm), Haemophilus influenzae (Hi), and Streptococcus pneumoniae (Sp) are the lead causes of bacterial meningitis. Detection of these pathogens from clinical specimens using traditional real-time PCR (rt-PCR) requires DNA extraction to remove the PCR inhibitors prior to testing, which is time consuming and labor intensive. In this study, five species-specific (Nm-sodC and ...
