Foals in the early stages of clinical disease may not show any specific signs, instead appearing ''''off-suck'''' (inspecting the dams udder can give some indication of when the foal last suckled). This may be accompanied by '''lethargy''', '''malaise''', frequent '''recumbancy''' and '''pyrexia'''. The bacteria may '''localise''' in different organs, producing clinical signs directly related to that organ:

The disease may then advance to '''septic shock'''. Clinical signs include prolonged recumbancy, depression, dehydration, and tachycardia with cold extremities, weak thready pulses, slow capillary refill time and muddy mucous membranes; indicative of hypotension. Dependant on the organs affected, signs of individual or multiple organ dysfunction may be present.
