Discuss population growth and the phases of a typical bacterial growth curve. Describe generation time for a bacterial population Explain how bacterial growth correlates to disease. Describe how environmental changes can alter the shape of a growth curve. Categorize microbes based on their preferred environmental niches (pH, temperature, oxygen and salt). Identify the biological properties that allow different classes of microbes to grow in extreme environments.

Regarding turbidity, which of the following statements is true? Group of answer choices Decreased bacterial concentration results in a turbid specimen due to increased light transmission Increased bacterial concentration results in a turbid specimen due to decreased light transmission. Increased bacterial concentration results in a clear specimen due to decreased light transmission.

Coliforms are commonly used as an indicator of drinking water quality. As we discussed, in March and April of 1993 there was a major outbreak of gastrointestinal illness in Milwaukee, Wisconsin caused by contamination in the public drinking water supply.  As summarized by MacKenzie et al.1, “throughout the period from February to April 1993, samples of treated water from both (water treatment) plants were negative for coliforms and were within the limits set by the Wisconsin Department of Natural Resources for water quality.”  Why, in this case, did coliforms remain at acceptable levels despite water contamination that resulted in over 400,000 cases of gastrointestinal illness?
