 Infection can be transmitted between horses in any of the following ways:

  • direct transmission during natural mating;
  • direct transmission during teasing. An infected teaser can transmit disease to mares through contact with his genitalia;
  • indirect transmission during teasing. A teaser can transmit infected vulval discharge between mares through genital or naso-genital contact;
  • transmission to mares if semen used for AI comes from infected stallions or has been contaminated with the bacteria during semen collection or processing;
  • indirect transmission via the hands and equipment of staff or veterinary surgeons who have handled the tail or genitalia of an infected horse.
