Epidemiological and virological investigations of equine influenza outbreaks in Ireland (2010-2012).

ABSTRACT:

Background

Outbreaks of equine influenza (EI) in endemic populations cause disruption and economic loss.

Objectives

To identify (i) factors involved in the spread of EI (ii) virus strains responsible for outbreaks (iii) single radial haemolysis (SRH) antibody levels correlating with protection against current virus strains (iv) evidence of vaccination breakdown.

Methods

RT-PCR, virus isolation and SRH were carried out on nasopharyngeal swabs and blood samples collected from horses, ponies and donkeys on affected premises. Data relating to 629 samples from 135 equidae were analysed.
