Summary Introduction
Introduction:
Bacteria are prokaryotic organisms that do not have a well-defined nucleus and an endomembrane system. They are classified as heterotrophs or autotrophs on the basis of their nutrition, as aerobes or anaerobes on the basis of their ability to survive in aerobic conditions, and as gram-positive or gram-negative on the basis of their ability to retain the

- Imagine you are a doctor treating a patient with a skin infection caused by a facultative anaerobic bacteria. You have tried several rounds of topical antibiotics, but the infection keeps returning. One of your interns suggests that you try hyperbaric chamber treatment – how would you respond? 1. “Hyperbaric chamber treatment might work because these bacteria won’t be able to obtain energy under low-oxygen conditions. Let’s give it a shot.” 2. “Hyperbaric chamber treatment won’t work because these bacteria can undergo anaerobic fermentation when oxygen levels are low. I’m prescribing oral antibiotics.” 3. “Hyperbaric chamber treatment won’t work because these bacteria can undergo aerobic respiration when oxygen is abundant. I’m going to prescribe oral antibiotics.” 4. “Hyperbaric chamber treatment might work because these bacteria won’t be able to obtain energy under high-oxygen conditions. Let’s give it a shot.”arrow_forwardConsumers are advised to avoid stuffing a turkey the night before cooking (where the stuffing would be made on the stove and then placed in the turkey), even though the turkey is refrigerated. A homemaker questions this advice and points out that the bacteria of human disease grow mainly at warm temperatures, not in the refrigerator. What explanation might you offer to counter this argument?arrow_forwardEndospores : A. are a dormant form of a bacterium AND are formed by members of medically relevant groups of bacteria. B. are a form of reproduction AND are formed by members of medically relevant groups of bacteria. C. are a dormant form of a bacterium AND are involved in anaerobic respiration. D. are formed by members of medically relevant groups of bacteria AND are involved in anaerobic respiration.arrow_forward
