The molecular epidemiology of equine group A rotaviruses (RVAs) in Ireland from 2011 to 2015 was investigated. Of 438 diagnostic specimens submitted from foals with enteric disease, 102 (23.3%) were positive for RVA using an immunochromatographic assay. G genotypes were determined for 76 equine RVAs, of which 68 (89.5%) were G3 and eight (10.5%) were G14. Of 18 RVAs (12 G3 and six G14) characterised by P genotyping, all were P[12]. G3P[12] and G14P[12] were the most prevalent genotypes of RVA in foals in Ireland, similar to other countries and consistent with previous studies in Ireland from 1999 to 2005. Phylogenetic analysis showed that G3P[12] and G14P[12] RVAs were related to equine RVAs recently detected in Europe, Brazil and South Africa, and to the vaccine strain H-2.
