CONTROL AND PREVENTION

• Outbreaks in non-endemic areas are probably best controlled by the slaughter of affected animals.
• The long incubation period of the disease, the high resistance of the causative agent and the presence of clinically healthy carriers make control of the disease difficult in endemic areas.
• Control of the disease depends upon elimination of the infection by culling infected horses and preventing spread by hygieneic precautions.
• Cleaning and disinfection will help to prevent the disease from spreading.
• This method of control is the most satisfactory and proven to be mandatory for large breeding companies in endemic areas.
• A killed formalised vaccine prepared from the yeast form of the fungus, administered subcutaneously in a dose of 5 ml once a year, has given good results.
• An attenuated vaccine was developed by exposure of the causative agent to high temperature.
• Horses inoculated subcutaneously with 3 ml in a single dose have given a higher protection rate.
