Quix Flashcards
The 2 under of Trypanosoma Brucei (T. Brucei)
- Animal parasite
- Causes nagana’s disease
Humans are prone to T.b. gambience due to the parasites’s resistance to trypanolytic factors and coexistence to malaria
Trypanosoma brucei
Whose reservoir of Dogs, pigs, sheep?
Trypanosoma brucei
Inflammation, swelling of lymph nodes
Winterbottom’s sign
The 2 winterbottom’s sign LAB DIAGNOSIS
Febrile stage: Blood and lymp nodes aspirate
Sleeping stage: CSF
