Oriental Sore 
Fig. 40. From a Stegomyia fasciata which had fed from the sore on two successive days 
and was dissected twenty-four hours after the last feed. 
Fig. 37. Form with two rhizoiDlasts. Length 5 /x. 
Fig. 38. Form without flagellum. Length 6 /x. 
Figs. 39 and 40. Partially developed forms. Length 4 and o fx respectively. 
Fig. 41. Typical flagellate form. Length 7 fx. 
PLATE XIII. 
All the figures from preparations of the rabbit’s blood agar cultures of the sore parasite 
fixed in Schaudinn’s fixative and stained by Heidenhain’s iron haematoxylin method, 
except figs. 9 and 15 which are from preparations made in the same manner direct from 
the sore. 
Fig. 1. Typical cultural form. Length 13 ,u.. 
Fig. 2. Dividing form very much discoloured. The fine line connecting the separating 
halves of the nuclear karyosome still retains the stain. Length 6 /x. 
Fig. 3. Typical form showing a clear interval between the end of the rhizoplast and the 
kinetonucleus. Length 9 fx. 
Fig. 4. Dividing form showing a condition of the kinetonucleus comparable with that of 
fig. 36, PI. I. Length 7 /x. 
Fig. 5. Dividing form showing two structures in the position of the kinetonucleus. 
Length 7 /x. 
Fig. 6. Form in which the nucleus contains two chromatin masses, possibly the divided 
karyosome. Length 7 /x. 
Fig. 7. Dividing form with two flagella. Length 8 fx. 
Fig. 8. Dividing form showing the fine line connecting the halves of the karyosome. 
The kinetonucleus also dividing. The protoplasm shows commencement of division 
in the form of a groove between the rhizoplasts. Length 7 /x. 
Fig. 9. Typical parasite from the sore. Compare with figs. 25 and 26 in PL XII, which 
have been dried and stained by Giemsa’s stain. 
Fig. 10. Dividing culture form. The halves of the kinetonucleus connected by the fine 
line like that which occurs in division of the karyosome of the nucleus. 
Fig. 11. Form showing the flagellum connected with a dome-shaped structure so 
frequently seen in the dried films (cf. PL XII, figs. 30-35). 
Fig. 12. Form with nuclear karyosome in division. 
Figs. 13 and 14. Forms with dividing kinetonucleus. 
Fig. 15. Parasite from the sore. Compare with fig. 9 and PL XII, figs. 25 and 26. 
Fig. 16. Dividing form with division of kinetonucleus completed. The halves of the 
karyosome connected by the long drawn out line. Length 6*5 /x. 
PLATE XIV. 
Figs. 1 and 2. Typical appearance of the oriental sore as it occurs on the faces of children 
in Bagdad. 
Fig. 3. Girl age 14 with oriental sore on the face and another on the right wrist. The 
sore on the face is of the type of a spreading ulcer (“female sore”), that on the wrist 
is a non-ulcerating growth (“male sore”). 
Fig. 4. The same case as fig. 3, showing the spreading ulcer on the face and its tendency 
to heal in one part as it spreads in another.
