Description: Segment 1 Scientists are shown working in a bacteriological laboratory. The metaphor of growing plants in gardens is used to describe how scientists grow cultures of bacteria. The process is demonstrated. First, the culture media is made. All the equipment needed is displayed, and a scientists demonstrates the process. Next, growing the bacteria is demonstrated. Bacteria from vinegar, water, rich earth and dust are grown. The growth of bacteria through cell division is shown in high magnification.

The bacteria are examined and shown in close up. The process of staining the bacteria in order to see them more clearly is demonstrated. The three common shapes of bacteria are shown in an illustration, and in high magnification. The film ends with intertitles explaining that most bacteria are harmless, a few are harmful and some are very useful. Time start: 00:06:50:01 Time end: 00:13:46:17 Length: 00:06:56:16
