Bacteria divide by transverse binary fission. Some cocci divide in random planes to form irregular clumps of individual cells looking under the microscope like bunches of grapes (staphylococci). Others always divide in the same plane, giving rise to chains of cells of varying length (streptococci). A few tend to remain in pairs, looking rather like beans, lying side-by-side or end-to-end depending on the species. Most bacilli simply elongate, constrict in the middle and separate into two daughter cells.

The Italian naturalist Agostino Bassi is usually credited with the first crucial observation: that muscardine, a serious disease of silkworms was invariably associated with the presence of a fungus, now known as Beauveria (Botrytis) bassiana. Bassi’s findings were first made known at a demonstration held at the University of Pavia in 1834 and published in two monographs during the next two years (6). Other discoveries followed and, once Robert Koch, while still a country doctor in Eastern Germany, had succeeded in establishing the role of Bacillus anthracis as the cause of anthrax in 1876 (7), the floodgates opened to a golden age of microbial discovery.

These studies, which have had profound ramifications, were eventually rewarded by the award of a Nobel Prize which they shared in 1969. FUNGI The lifestyle of viruses, existing in an intimate relationship with the cells on which they depend for survival, has made them a much more difficult target than bacteria for selectively active therapeutic agents. Very few antiviral agents were available until the HIV pandemic concentrated the minds of scientists inside and outside the pharmaceutical industry, and even now few, if any, of the agents available to the prescriber are reliably curative (see Chapter 8).
