Research conducted by the University of Saskatchewan is expected to change the manner in which porcine ear-tip necrosis is controlled. Porcine ear-tip necrosis, a painful infection that causes the ear of the pig to turn black and rot away, was first identified in the 1950s, is found in all regions where pigs are raised.
As part of a blind clinical trial conducted by the University of Saskatchewan, researchers have identified Fusobacterium necrophorum as the agent responsible for this condition. Dr. Mateus Costa, an associate professor with the Western College of Veterinary Medicine and an adjunct professor at Utrecht University, says this dispels the theory that ear necrosis is associated with mycotoxin, with porcine circovirus or other agents.
Quote-Dr. Mateus Costa-University of Saskatchewan:
Now we know that Fusobacterium necrophorum causes the disease so it will have a deep impact on how we handle it, how we manage it, how we control and treat it. The agent is a bacterium so antibiotics are in theory useful for trying to control the disease, although you most definitely want to work with your veterinarian to identify what antibiotics to use. Not just any antibiotic would work. It is a very challenging bacterium to deal with for two reasons.
It is present in every and any pig.
