This trypanosome is found also in domestic cattle, 
dogs, pigs, and rarely also in sheep and goats. 
Symptoms. —(i) Weakness. (2) Intermittent fever. 
(3) Oedema of testes, but not elsewhere, as in Ngana. 
(4) Paraplegia. The disease lasts many months, or 
over a year, and recovery may occur. 
Blood Examination.—Parasites may be scanty at 
first and more numerous when the febrile attacks are 
well marked. Later they again become rare, but may 
be abundant before death. 
Morphology. —Three forms occur :—(1) Tadpole 
form in the early stage of the disease, 11-13/* by 
o*l 8-1/*. (2) Long forms, 26-30/* by 1*6-2/* a few days 
before death. (3) Stumpy forms, 16-19/* by 3*4-3*5/^. 
According to Luhe, No. (1) represent an indif¬ 
ferent ; No. (2) a male (?); No. (3) a female trypanosome. 
Transmission. — Gl. palpalis is capable of trans¬ 
mitting infection. 
8. T. cazalboui (Laveran, 1906).—The cause of 
Souma, a fatal disease of ruminants in French Soudan. 
Symptoms. —Oedema, paresis, and cutaneous erup¬ 
tions urticarial in character. It is non-infective for 
monkeys, dogs, and rodents, but goats and sheep are 
readily infected. 
Transmission is by Stomoxys bouffardi. 
9. T . soudanense. —The cause of a disease of 
dromedaries in Sudan, probably a variety of Surra. 
The pathogenic action on mice is similar to that of 
the trypanosomes of El Debab and Zousfana. 
10. T. pecaudi. —The cause of Baleri, a disease of 
equines in French Soudan. The symptoms are (a) 
repeated febrile attacks, ( b ) eye symptoms, (r) skin 
eruptions and plaques, resembling those of Dourine, 
(d) oedema of genitals. Two forms occur (1) 25-35 
by 1*5/*, (2) 14-20 by 3-4/*. It resembles T. dimorphum.
