In this genus, vesicle trafficking to the flagellar pocket is predicted by the GPI valence hypothesis. Paul Ehrlich found that the blindness-causing atoxyl kills organisms in this genus, before discovering (-5[1])that syphilis can be treated by its derivative salvarsan. The anti-hair growth drug eflornithine kills organisms in this genus. By inhibiting replication of interlocked mini- and maxicircles in their kDNA, organisms of this genus are killed by the intercalator (*) ethidium bromide. This genus uses variant surface glycoproteins, or VSGs, to avoid the immune system. The “kissing bug” transmits a species in this genus discovered by Carlos Chagas. After crossing the blood-brain barrier, (10[1])the brucei (“BRUCE-ee”) species in this genus disrupts the sleep-wake cycle. For 10 points, name this genus of protozoans whose transmission through tsetse flies (-5[1])causes nagana and African sleeping sickness. ■END■
