Helminth infection and control

In two widely separated places of Lake Bunyonyi at Chabahinga, near Kabale, and in Muko, we found the same three species of fresh water snails: 1. (1) Pl. pfeifferi Krauss. 2. (2) B. coulboisi Bourg. and B. mutandaensis Preston. 3. (3) L. natalensis (undussumae) von Martens. Bulinus were the most abundant, Planorbis also numerous, and Lymnaea comparatively rare. Amongst the Planorbis (and Bulinus) of Chabahinga we found none infected with Schistosoma cercariae, but amongst the Planorbis at Muko we found two specimens shedding Schistosoma cercariae. Both Planorbis died before we had time to try an animal experiment. We did not examine the natives of Muko, but amongst those of Chabahinga, near Kabale, we found a few boys infected with S. mansoni. Infection, however, was very light, and none of the affected complained of any symptoms. S. mansoni thus exists at an altitude of 6,300 feet.
