My mare, whom I mentioned I've been trying to get in foal for about four yrs now, has suffered from Progressive Ethmoid Haematoma. Until last week she had not had a sinus swab cultured to establish if there were any bacteria present as it wasn't deemed necessary despite an almost persistent purulent discharge from one or both nostrils. Results came back positive today with heavy 'Streptococcus zooepidemicus' found & another bacteria which I forget the name of at present. She has obviously had this for the four years she's had the PEH and I don't know why this wasn't checked for when she went for initial treatment. Could the strep. zooepidemicus be related to her not getting in foal? I have just read that it causes endometritis in susceptible mares. Is this correct, and how are the two related? Is endometritis curable? Also, is it contagious between horses and are other pregnant mares at risk? This is really worrying and the non-pregnant issue seems to be far more complex now.. Please help!
The bacteria Streptocuccus zooepidemicus (or more correctly, Streptococcus equi, subspecies zooepidemicus) is a common respiratory pathogen in the equine, and is also the most common cause of endometritis (inflammation of the endometrium). An endometritis situation would not be caused by a systemic infection, but rather the pathogen gaining access to the reproductive tract directly. The uterine swab culture and cytology is the diagnostic tool used to identify the presence or absence of this pathogen in utero, which - if detected - is easily and effectively treated with a series of uterine infusions of a suitable antibiotic solution.
As it is a bacteria and respiratory, transmission to other animals is possible, but not a significant cause for concern. It would be unlikely to be an issue in pregnant mares, except for those mares with an incompetency of the cervix, wherein this pathogen is the leading cause of placentitis. Note again though, that this will require direct access to the vagina and cervix, and not be as a result of a systemic infection.
Jos, thank you so much for such a prompt, informative reply. It's really appreciated
