In order to facilitate optimal plant DNA quantitation and identification, an assay has been developed that uses generic plant PCR primers that amplify a region in the chloroplast genome of plant samples. The assay uses the SYBR green detection dye to detect the PCR product with a universal PCR primer set to the large subunit of ribulose bisphosphate carboxylase, rbcL, but can be used with any o...

Dengue fever is an emerging disease in Pakistan with uninterrupted increase in number of cases since 2006 Dengue fever epidemic in Lahore Pakistan. This study was planed to identify serotypes of dengue virus (DENV) involved in epidemic of 2008. The patients were screened in the microbiology laboratory with immunochromatographic kits then confirmed by antibody capture Enzyme linked immunosorbent...

Background and Aims: Accurate and rapid diagnosis is necessary for effective control and prevention of foot-and-mouth disease (FMD). In present study, was evaluated real time reverse transcription-polymerase chain reaction (rRT-PCR) assay along with diagnostic routine methods for the detection of all seven serotypes of FMD virus (FMDV), namely O, C, A, SAT1, 2, 3 and Asia 1 in biological sample...

results results of the current study showed that the minimum inhibitory concentration value of cinnamaldehyde against m. tuberculosis was 200 µg/ml. moreover, rt-pcr data showed that a total of 25 genes were regulated by the cinnamaldehyde. of these, 12 genes were up-regulated, and 13 genes were down-regulated. conclusions cinnamaldehyde is a pattern to expand the new anti-tb drugs, because the...

stevens-johnson syndrome (sjs) and toxic epidermal necrolysis (ten) are severe adverse cutaneous reactions to drugs. we describe the case of a 19 year old patient with sjs/ten overlap syndrome, who developed severe interstitial pneumonia after she had received antiepileptic drugs. a cytomegalovirus infection was diagnosed by real time polymerase chain reaction (rt-pcr) detection on bronchoalveo...

results all eight candida species were successfully detected, identified and quantitated based on the icl gene. a seven-log range of the gene copy number and a minimum detection limit of 103 copies were achieved. conclusions a one-tube absolute quantification real-time pcr that differentiates medically important candida species via individual unique melting temperature was achieved. analytical ...

Molecular methods are being increasingly applied to detect, quantify and study microbial populations in food or during food processes. Among these methods, PCR-based techniques have been the subject of considerable focus and ISO guidelines have been established for the detection of food-borne pathogens. More particularly, real-time quantitative PCR (qPCR) is considered as a method of choice for...

Brucellosis is primarily a worldwide zoonotic disease caused by Brucella species. The genus Brucella contains highly infectious species that are classified as biological threat agents. In this regard, the identification of Brucella can be a time-consuming and labor-intensive process posing a real risk of laboratory-acquired infection to the laboratory staff. This stud...

We present a Bayesian hierarchical model for quantitative real-time polymerase chain reaction (PCR) data, aiming at relative quantification of DNA copy number in different biological samples. The model is specified in terms of a hidden Markov model for fluorescence intensities measured at successive cycles of the polymerase chain reaction. The efficiency of the reaction is assumed to depend on ...
