Loop-mediated isothermal amplification (LAMP) test is widely used in molecular diagnostics as a point-of-care technique alternative to traditional PCR especially resource-limited countries. LAMP has been recently diagnose leptospirosis. Therefore, we undertook systematic review and meta-analysis compare the accuracy of with diagnosis Sixty-one studies were extracted from three international dat...

The objective of this study was to know the herd and animal level prevalence of Q fever in domestic ruminants in some selected districts in Bangladesh. Randomly collected 111 bulk milk and 94 sera samples of cattle, sheep, and goats were tested by indirect ELISA (iELISA). DNA extracted from 23 aborted fetal membranes was analyzed by real time (rt) PCR. The positive cut-off value of iELISA in bu...

A loop-mediated isothermal amplification (LAMP) assay allows rapid diagnosis of Toxoplasma gondii infection. In the present study, the LAMP assay was evaluated using blood from both naturally and experimentally infected pigs. The sensitivity of the LAMP assay was compared with that of Q-PCR. Both assays detected T. gondii in the blood of experimentally infected pigs, with 100% agreement. In inf...

SUMMARY Q-Gene is an application for the processing of quantitative real-time RT-PCR data. It offers the user the possibility to freely choose between two principally different procedures to calculate normalized gene expressions as either means of Normalized Expressions or Mean Normalized Expressions. In this contribution it will be shown that the calculation of Mean Normalized Expressions has ...

The aim of this study was to develop a LightCycler-based real-time PCR assay for monitoring the Epstein-Barr virus (EBV) DNA load in unfractionated whole blood. This assay was compared with quantitative competitive PCR (Q-PCR) for EBV. The LightCycler-based assay was highly sensitive and reproducible when quantifying plasmid DNA in either the presence or absence of healthy donor blood DNA. Ampl...

Pre- and postnatal diagnosis of chromosomal aberrations is generally based on conventional cytogenetic analysis. In this paper, we have devised a quantitative polymerase chain reaction (Q-PCR) method to determine gene dose effects and applied it in cases of regular trisomy 21 as a model. The method is based on quantitative assessment of PCR products after using primers amplifying DNA fragments ...

Molecular surveys of marine picoeukaryotes have revealed a large number of sequences unrelated to cultured organisms, such as those forming the marine stramenopile (MAST)-4 clade. Recent FISH (fluorescent in situ hybridization) data have shown that MAST-4 cells are uncultured heterotrophic flagellates of 2-3 microm in size that have a global distribution in non-polar marine waters. However, FIS...

Hybrid gene PML-RARα is the molecular target found in most cases of acute promyelocytic leukemia (APL) and has been used for diagnosis and minimal residual disease studies. The standard molecular technique employed is qualitative reverse transcriptase-polymerase chain reaction (RT-PCR), but with the emergence of real time PCR (Q-PCR), PML-RARα gene detection approaches have been described allow...

Bovine tuberculosis (BTB) is a zoonotic disease caused by Mycobacterium bovis, a member of the Mycobacterium tuberculosis complex (MTC). The quick and specific detection of this species is of extreme importance, since BTB may cause economic impacts, in addition to presenting imminent risks to human health. In the present study a nested real-time PCR test (nested q-PCR) was used in post-mortem e...

Tuberculosis (TB) is a major public health problem in Nepal and ranks as one of the most prevalent communicable diseases throughout the country. In Nepal, 45% of total population is infected with TB and 40,000 people get TB every year. Twenty thousand new sputum positive cases are seen every year and 5000-7000 people die each year from TB. Thirty sputum samples were collected from Sukraraj Trop...
