Validation of an influenza virus A 5′Taq nuclease assay for the detection of equine influenza virus A RNA in nasal swab samples

RNA Extraction from Equine Samples for Equine Influenza Virus

The primary goals of this chapter are to discuss common viral RNA isolation and purification methods that are routinely used by various diagnostic laboratories and to highlight the advantages and drawbacks of each method and to identify the most suitable and reliable method to increase the sensitivity and specificity of RT-PCR assays for the detection of equine influenza virus (EIV) in clinical specimens. Our experiences and review of literature show that magnetic bead-based nucleic extraction methods (manual and automatic) work well for isolation and purification of EIV RNA from nasal swab specimens. Furthermore, most of the information presented in this chapter could be directly applicable to isolation and purification of nucleic acids (both DNA and RNA) from other equine clinical samples.

Overview of the epidemiology of equine influenza in the Australian outbreak

This overview of the equine influenza (EI) epidemic as it occurred in two Australian states, New South Wales and Queensland, in 2007 describes the functions and activities of the epidemiology teams that were engaged during the outbreak and also identifies key features of the epidemiology of EI during the outbreak.
