A real-time RT-PCR assay utilising light upon extension fluorogenic primer (LUX RT-PCR) was developed for the rapid and efficient detection of avian influenza viruses (AIV). The assay detected each of the AIV isolates tested (16/16) and gave negative results with heterologous pathogens (17/17). The detection limit of the assay proved to be 10-0.5 EID50/0.2 ml and 101.5 EID50/0.2 ml in allantoic fluid of virus-infected embryonated chicken eggs and in spiked chicken faeces samples, respectively. Based on its specificity, sensitivity and relative simplicity, the LUX RT-PCR assay provides a novel, rapid and cost-effective diagnostic tool for avian influenza surveillance and monitoring programs.

Fusarium head blight disease (FHB) in wheat, caused by Fusarium graminearum species complex (Fg complex), is a very serious disease threatening wheat production worldwide. Polymerase chain reaction (PCR) based methods have been established for rapid and quantitative detection of many plant pathogens. In this study, a specific pair of primers was designed based on the sequence of DNA fragment (740 bp) amplified by a microsatellite primer M13 from Fg complex isolates. This pair of primers was able to amplify a 380 bp fragment from all Fg complex isolates but not from any other tested fungal species. Using this pair of primers, a real-time PCR assay was developed to quantitatively detect small amounts of Fg complex in wheat seeds. This sensitive and quantitative detection assay could be useful in epidemiological studies and assessment of mycotoxin contamination in wheat seeds.
