About The Cover

A human eosinophil (upper right) is adhering to the surface of a larval schistosome that was coated with antibodies from patients suffering from schistosomiasis. The cell membrane is broken and granules are spilling from the cell (×11,000). See page 1065. [Courtesy of John P. Caulfield, Brigham and Women's Hospital, Harvard Medical School, Boston, MA 02115]
