Abstract
The present report is an account of observations made in Bagdad during the year 1910 (March to November) on the Oriental Sore as it occurs in this part of the world. Though the sore of Bagdad may not differ very markedly from that of other places, it is so common here that all stages and types of the sore may easily be studied, and such points as the early age of infection, immunity, and duration of the disease are very clearly exemplified. Accordingly, a more or less complete account of this disease of Bagdad, known locally as the Date boil or Arabic “Uchut,” will be given, though descriptions of the sore as it occurs in several parts of the world have been published by other observers. During the investigations various side issues arose, and as these suggest certain interesting points, three sections have been added dealing with (1) the life history of Lankesteria culicis (Ross) a gregarine of Stegomyia fasciata, (2) Haemogregarina canis and its development both in the dog and the tick Rhipicephalus sanguineus, and (3) Her-petomonas muscae domesticae, and other flagellates of the house-fly.
