Nagana

Nagana is an animal disease that occurs in Africa , which significantly restricts livestock farming in the African "Tsetsa belt" (14 ° N to 29 ° S) and is caused by trypanosomes . It is transmitted by the tsetse fly .

• Trypanosoma brucei brucei : Cattle rarely or never become ill, but it is fatal to horses, donkeys, dogs, cats and various rodents.
• Trypanosoma vivax is the causative agent of the Nagana in cattle and sheep (Souma).
• Trypanosoma congolense is the most virulent pathogen in ruminants (Gambia fever).
• Trypanosoma simiae is particularly fatal in pigs, is sometimes referred to as nagana.

The original reservoir of parasites consists of immune or latently infected wild animals from Africa. Infections with different types of trypanosomes are common, also with the pathogens of human pathogenic African trypanosomiasis (sleeping sickness). Humans do not get sick with Nagana, but they can be infected with closely related pathogens (Tb gambiense; Tb rhodesiense), which can lead to sleeping sickness.
