Horses with Acute and Subacute Grass Sickness have 10 times more anaerobic cocci (clostridium) than healthy ones.


If positive for the clostridium bacteria listed below then times when pasture is high in protein or carbohydrate become an increased risk factor,  triggering an increase in clostridium.​

The use of an ivermectin anthelmintic significantly increases the risk of EGS.
