Trypanosoma vivax is a parasite species in the genus Trypanosoma. It causes the disease nagana, also known as animal trypanosomiasis, affecting cattle or wild mammals such as the nyala. It is mainly occurring in West Africa, although it has spread to South America.[1]
Symptoms of T. vivax include "rapid weight loss, lethargy, weakness, clumsiness, pale mucosa, swelling of superficial lymph nodes, anemia, and fluctuating pyrexia, causing[...]a drop in animal productivity."[2]
A novel proline racemase of medical and veterinary importance has been described in T. vivax (B8LFE4).[3]
The smallest variable surface glycoprotein (40 kDa in size) to date has been found in T. vivax, which bears little carbohydrate.[4]
It also produces vivapain, a cysteine peptidase.[5]
