This is not Bangs. It is not contagious within the herd and does not infect humans. It is not a bacteria or a virus. Everyone should use caution and dispose of any dead carcasses and afterbirth by burying and burning. Neospora in dogs and coyotes are infected through consuming raw meat of an infected, deer, goat, bison, horse or cow. The parasite lives in the muscle and nerves of the infected meat. It is NOT bloodborne. The canines that have the disease have very sick pups, most don't survive. This may cause the disease to be cyclic and occur more frequently as the population of coyotes peaks.
An infected cow may abort once, or several times or never abort. The Neoguard vaccine should be used on pregnant cattle if your cattle are at risk. Get your dogs tested for Neospora if you are concerned.
There are some studies that indicate mice and rats can carry the oocytes and contaminate feed. That may be why this disease seems more common in dairy operations.
When your cattle abort, get a Vet involved. Run abortion profiles and post the fetus. You will gain valuable information about your herd.
