Next generation sequencing of DNA from nematode eggs has been utilised to give the first account of the equine ‘nemabiome’. In all equine faecal samples investigated, multiple species of Strongylidae were detected; ranging from 7.5 (SEM 0.79) with 99+% identity to sequences in the NCBI database to 13.3 (SEM 0.80) with 90+% identity. This range is typical of the number of species described previously in morphological studies using large quantities of digesta per animal. However, the current method is non-invasive, relies on DNA analysis avoiding the need for specialist microscopy identification and can be carried out with small samples providing significant advantages over current methods.
