Trypanosoma suis Ochmann, 1905

Trypanosoma suis is a species of excavate trypanosome in the genus Trypanosoma that causes one form of the surra disease in animals. It infects pigs. It does not infect humans.
Discovery
[edit]Trypanosoma suis was first encountered and described by Ochmann in 1905. He found the parasite in a herd of sick pigs in Dar-es-Salaam, Tanzania. Hence the name as the word suis means pig. Eventually it was lost in consecutive renaming of the parasite until the 1950s.
Rediscovered
[edit]Trypanosoma suis is rarely seen and has been lost and rediscovered several times. In the 1950s T. suis is rediscovered in Burundi by two Belgian researchers.[1]
T. suis remains the most rare member of the Salivarian trypanosomes. The only isolated specimen known of this species is kept at the Kenya Trypanosomiasis Research Institute, Nairobi.[2]
The next detection was only made by Hutchinson and Gibson 2015. Newly developed molecular biology methods allowed the discovery of an uncertain Trypanosoma in samples from a few years prior from Tanzania and the Central African Republic. This molecular profile was then applied to blood smear slides from 1952 and 1953, a match was found, and the rediscovery of T. suis was declared.[3]: 323 : 335
Transmission
[edit]The parasite is known to be transmitted by the tsetse fly[4] Glossina brevipalpis.[1]
