Psittacosis is a well-recognised zoonotic disease of birds that can cause serious flu-like symptoms and pneumonia in humans.
Until 2014, it had not been considered as a cause of abortion in horses.
A second cluster of infections at the same university has confirmed Psittacosis to be the cause.
A scientific paper that was presented at the Bain Fallon Equine Conference last week, confirmed that there have been 30 cases of Psittacosis abortion on 15 separate properties in NSW in 2016.
I am writing today to advise you that our practice has just had laboratory confirmation of a Psittacosis abortion in a mare on the Darling Downs in Queensland.
As Psittacosis is a known zoonotic infection that can now be transmitted from horses to humans, there are workplace health and safety implications for all stud managers when staff deal with aborting mares.
Students and staff that were infected with the Psittacosis bacterium were wearing gloves, overalls and boots at the time of transmission. For this reason, it is now recommended that anyone coming into close contact with an aborting mare, foal or placenta should, in future, be wearing, overalls, gloves, P2 mask and eye protection.
It is important to note that in the recent study, 12 of the infected mares had live foals that quickly succumbed to severe respiratory infections, 8 of which were fatal. During this period the foals are very infectious to humans.
