Question
Using your text and websites such as those listed above, research 5 bacteria: Streptococcus, Escherichia, Arthrospira (fr. Spirulina), Anabaena, Lactobacilus, and 1 more of your choice _____________. Identify the shape, mode of nutrition, locations found, role in the ecosystem, and disease and host of these 5 bacteria and 1 more of your choice (6 total). Most bacteria are harmless (or beneficial), though a few are pathogenic bacteria. You may find websites from the Center for Disease Control (CDC) and National Institute of Health (NIH) helpful for the pathogenic organisms. You are not turning in the data you collect; your data will help prepare you for your laboratory quiz.
