Then Fleming set out for Rochester, Minn., and other research centers to do some personal research: he wants to know what details other workers have found out about the way penicillin works in the bloodstream. He also wants to learn more about the newer antibiotics: streptomycin, neomycin and aureomycin...
...carrying two tiny wooden boxes. Inside the boxes, carefully packed between a layer of mud and some wet weeds, were 200 tiny (¼-in. diameter) snails (Bullinus truncatus). The snails were heavily infested with larvae of the fluke Schistosoma haematobium, which burrows under the skin and travels through the bloodstream to nest in and around the bladder. The infestation causes Bilharziasis (a form of schistosomiasis), resulting in passage of blood in the urine. Half of Egypt's 19,000,000 people suffer from it; throughout Africa and Asia, an estimated 400 million people have related forms of schistosomiasis...
