Abstract

In this work, we explore a new hybridization technology using barcoded probes which has large-scale multiplexing capability. We used influenza virus to test whether the technology has application in virus diagnostics. Typing of influenza virus strains is an important aspect of global health surveillance. Standard typing procedures use serological or amplification-based assays performed sequentially. By comparison, the hybridization technology was correctly able to detect, type and subtype influenza A and B virus strains directly from clinical samples in a single reaction without prior virus isolation or amplification. Whilst currently not as sensitive as amplification-based assays, these results are a first-step towards application of this technology to the detection and typing of influenza and other viruses.

Figure 1
Detection, typing, and subtyping of influenza virus isolates. RNA extracts of influenza isolates were (A) detected and typed; and simultaneously sub-typed as strains of (B) influenza A or (C) influenza B. (D) A new probe based on PB1 sequence (probe 7) for the detection of influenza A is shown in comparison to the original MP probe (probe 1).

Determination of the linear range of the FluST assay. A series of six 10-fold dilutions of each of an isolate previously typed and sub-typed as either (A) A-H1N1pdm09 strain or (B) B-Victoria strain. Counts from both typing and sub-typing probes are given for each isolate.
