EQUINE MALARIA 
Synonyms: Piroplasmosis of horses; South African horse sickness; 
“biliary fever.” 
Characterization. This affection of horses is characterized by a 
high temperature and a yellowish tint of the mucous membranes. 
The spleen is enlarged and the blood contains Piroplasma equt. 
History. The disease appears to have been first described by 
Wiltshire in 1883. Guglielmi discovered the parasite of this affection 
in 1899, and Rickmann found it in a large number of horses that died 
of “horse sickness.’ A good description of this affection was given 
by Theiler in 1901. 
Geographical distribution. This disease appears to be very largely 
restricted to Southern Africa and Europe. The disease known as 
malarial fever in the United States has not been demonstrated to be 
due to a piroplasma. Peters reported malaria in horses in the West. 
The diagnosis was made from the symptoms and lesions as he did not 
find the Piroplasma.
