Surra (from the
Marathi sūra, meaning the sound of heavy breathing through nostrils, of imitative origin) is a disease of vertebrate animals. The disease is caused by
protozoan trypanosomes of several species which infect the blood of the vertebrate host, causing fever, weakness, and lethargy which lead to weight loss and anemia. In some animals the disease is fatal unless treated.
An acute form of the disease, which is generally fatal unless treated, occurs in horses, donkeys, mules, cattle, buffalo, deer camels, llamas, dogs and cats. This form is caused by
Trypanosoma evansi (
Steel 1885)
Balbiani 1888, and is transmitted by
horse-flies, and also by the vampire bat,
Desmodus rotundus, in
South-America. This form occurs in South America, Northern Africa, and the Middle East. This was the first form of pathogenic trypanosome discovered and was first described by
Griffith Evans in
1880 while working in
India.
A chronic form of the disease, which is milder but persistent, occurs in pigs, sheep, and goats. This form is caused by
Trypanosoma suis and is transmitted by
tsetse. This form occurs in Africa.
