Mastitis in ewesMastitis in ewes can be fatal and usually results in the end of her productive life.The usual presentation is acute gangrenous mastitis (blue or black bag) usually caused by either Staphylococcus Aureus or Mannheimia Haemolytica. S. Aureus is normally present on the teat skin but damage to the teat ends allows it access into the teat canal and causes mastitis.M. Haemolytica is present in the tonsils of lambs so colonises the udder during suckling. The bacteria produces toxins which prevent blood flow and cause the udder to turn blue/black hence the name. This often occurs around peak lactation (three to six weeks post-lambing) and the initial clinical signs may be as subtle as a ewe looking lame or a lamb bleating because it's hungry. The disease then rapidly progresses.The risk factors include:
