Summary

# Editorial Summary: Neuropathogenic EHV-1 Variants in Polish Abortion Cases Equine herpesvirus 1 (EHV-1) presents a significant challenge to stud farm management, with certain genetic variants capable of causing neurological disease (equine herpesvirus myeloencephalopathy, or EHM) in addition to reproductive losses. Stasiak and colleagues investigated Polish abortion isolates to establish whether neuropathogenic strains—specifically those carrying the G2254 mutation—were present in their region, recognising that EHM incidence had escalated considerably across Western Europe and North America during the preceding decade. By genetically characterising EHV-1 samples collected from aborted pregnancies on Polish breeding establishments, the researchers determined the prevalence of both neuropathogenic (G2254) and non-neuropathogenic (A2254) variants within their dataset. This work matters for equine practitioners because it provides regional epidemiological data essential for risk assessment and biosecurity planning; identifying whether neuropathogenic strains are circulating in a given population allows stud farms, vets, and breeding programmes to implement appropriate quarantine protocols and vaccination strategies to prevent both neurological outbreaks and reproductive failure.

Practical Takeaways

  • Neuropathogenic EHV-1 strains capable of causing neurological disease are circulating in Polish breeding populations and associated with abortion outbreaks
  • Genetic typing of EHV-1 isolates can distinguish between neuropathogenic and non-neuropathogenic variants to inform outbreak management and prognosis
  • Increased vigilance and biosecurity protocols are warranted given rising EHM incidence in Western countries

Key Findings

  • Neuropathogenic G2254 variant of EHV-1 was detected among isolates associated with abortions in Polish stud farms
  • Study documents prevalence of both neuropathogenic (G2254) and non-neuropathogenic (A2254) EHV-1 variants in Poland
