Contagious Equine Metritis

Description

Contagious equine metritis (CEM) is a contagious venereal disease caused by Taylorella (formerly Haemophilus) equigenitalis and is characterised by a mucopurulent vaginal discharge and early return to oestrus. Infected stallions are asymptomatic and act as reservoirs of T. equigenitalis. Usually, only 30-40% of mares served by an infected stallion develop clinical signs and most infected mares recover uneventfully. CEM is commonly associated with an early return to oestrus, but only rarely with abortion. T equigenitalis may persist for 2-10 weeks in some mares, but may also establish a carrier state for many months in others.

Courier services and specimen delivery

For NSW submissions, please contact the relevant Customer Service team for courier account details and to order consignment notes.

For submitters outside of NSW, Couriers can be contacted directly to make bookings and arrange collection of packages at the submitters own cost.

Commercial couriers may use either road or air transport and specimens should therefore be packed in accordance with International Air Transport Association (IATA) requirements. Most submission sent by veterinarians to the APHL for testing are defined as “Biological Substance Category B” and must be packed according to the IATA packing instructions 650 (Biological Substance Category B). As requirements for transport can change, customers should consult with their transport agent to obtain current requirements.

Samples may also be hand delivered to the site during normal business hours (8.30am - 4.30pm).
