Get the Facts
- Most bacteria are harmless. Many are even beneficial. Find out more about bacteria. What is the difference between and what are some examples of saprophytic, pathogenic, and nonpathogenic bacteria? What are some of the ways in which bacteria are beneficial? What diseases are caused by bacteria? What are nitrogen-fixing bacteria and how are they important to soil fertility? What would the world be like if there were no bacteria? You could use the answers in a project report. You could also prepare a data table for display showing diagrams of and listing the human diseases caused by the three major morphological types of bacteria:
- bacilli—rod-shaped
- cocci—round
- spirilla—spiral-shaped
- Antiseptics and disinfectants are used to control the growth of bacteria and to prevent infections. These chemicals cannot be used to treat internal body infections. Other chemicals called antibiotics are used to control bacterial growths inside the bodies of animals. Find out more about these special life-saving "miracle drugs." How long have they been used? What was the first antibiotic used, who discovered it, and how was it discovered?
(See the sample data table in Figure 19.3.)
