PERACUTE INFECTION

• The onset of a peracute reaction is sudden and unexpected. It is manifested by inappetence, high fever, depression, deep congestion of visible mucous membranes, severe panting and racing pulse.
• Death occurs within two or three days, even before mucosal erosions develop. The peracute reactions are not common and occur most frequently in young calves and exotic animals.
