I have not had experience with this particularly vicious mastitis, thank God. I have read about it, and have found some good informational links which I am going to include in this post. One thing to be aware of – this (and other types) mastitis can be spread from one goat to another so do wash your hands very thoroughly before milking the next (or do this one last) if you even suspect your doe has black mastitis.
Some of the links will take you to a page which has more information but includes mention of black mastitis, so you will need to do a “find” on the page for the word gangrene or black mastitis.
Gangrene Mastitis Blog – This blog chronicles the experience had by Andi and her owner. Please be advised there are graphic photos of the affected teat.
Natural Cures for Top 10 Goat Ailments from Acres U.S.A. This link contains excerpts from Pat Coleby’s book Natural Goat Care and contains several treatments for mastitis, including black mastitis. I have had the pleasure of corresponding with Pat by snail mail, she is very knowledgeable about our caprine friends.
Quote from Saanendoah:
Gangrene mastitis is not a particular “kind” of mastitis, but most often the result of the most common mastitis’ causing bacteria, coagulase-positive Staphylococcus aureus. Staph aureus can produce alpha toxin, a potent vasoconstrictor that is thought to be involved in the pathogenesis of gangrene mastitis. Other common pathogens are sometimes involved, including coagulase-negative Staphylococci, and any number of Gram-positive, Gram-negative, and coliforms bugs.
