Normal ocular flora

  • The conjunctival sac of the equine eye usually has a normal bacterial and fungal flora.
  • Studies from around the world have shown that prevalence rates vary for individual organisms often reflecting geographical locations, local environment and management practices, seasonal changes, disparity of culture collection, culture media used and animal bias.
  • Almost all studies agree that gram-positive bacteria predominate.
  • Anaerobic bacteria are not usually recovered from the external eye of normal horses.
