...parasite with a microscope, and Dr. Charles Donovan demonstrated that specimens could be extracted from the spleen. In their honor, the deadly parasite is called Leishmania donovani. Variants of kala-azar are found in southern Europe and South America. A complex treatment involving daily injections of a potentially toxic, antimony-based compound (as in the drug Pentostam) has been available for a half-century...
...bacteria. Along with thousands of fish killed and infected, as many as 28 people who have come into contact with the water have developed symptoms including skin rashes, respiratory problems and memory loss. The culprit appears to be an obscure microbe called Pfiesteria piscicida, which under certain circumstances turns toxic. Though the precise trigger remains unclear, suspicion has fallen on agricultural runoffs, particularly from the region's numerous chicken farms. In addition to closing waterways, Governor Parris Glendening has named a panel to investigate the runoff problem and has called a summit of Governors from surrounding states to consider regional...
Scientists say it is too soon to know why these Pfiesteria became toxic, but most suspect "nutrient loading," that is, an excess of nutrition pouring into the waters in which the bacteria live. The nutrients could come from many sources, including sewage- treatment plants. But in an area that is home to about 600 million chickens (outnumbering humans about 500 to 1), poultry is the leading suspect. Chicken manure is commonly used as fertilizer on farmlands around the affected waterways. Environmentalists say when it runs off into the water, it brings excessive levels of nitrogen. They have called for restrictions...
