When Vibrio is not Vibrio: misidentified Aeromonas sp. associated with equine abortions and neonatal death, revealed by MALDI-TOF and 16S rRNA sequencing

Share:

"Highlights

  • API 20NE misidentified Vibrio sp. from 27 equine necropsies between 1996-2022.
  • MALDI-TOF and 16S rRNA identified 96% of 25 cultivable strains as Aeromonas sp.
  • Strains came from abortions and neonatal deaths with causality not always established.
  • Recurrent isolations since 2014 point Aeromonas sp. as emergent equine opportunists."
