Question

in your own words, answer the following questions in a paragraph: 1. which is generally considered more dangerous- gram positive or gram negative bacteria? (1 pt) 2. why is this the case? (3 pts) in your answer, include an explanation of how septic shock can be deadly. (1 pt) note: please do not copy directly from your notes sheet. you need to put your answer in your own words.

Explanation:

Gram - negative bacteria are generally more dangerous. Their outer membrane has lipopolysaccharides (endotoxins). When these bacteria die or are disrupted, endotoxins are released, triggering a strong immune response. This can lead to septic shock, where the body's inflammatory response becomes uncontrolled, causing widespread vasodilation, drop in blood pressure, organ hypoperfusion, and ultimately multiple organ failure, which is often fatal. In contrast, gram - positive bacteria's exotoxins, while harmful, don't typically trigger such a severe systemic response related to septic shock as frequently as gram - negative bacteria's endotoxins.

Answer:

Gram - negative bacteria are generally more dangerous. Their outer membrane contains lipopolysaccharides (endotoxins). When gram - negative bacteria are destroyed, these endotoxins are released, initiating a potent immune response. This can lead to septic shock, during which the body's inflammatory response spirals out of control. Widespread vasodilation occurs, causing blood pressure to plummet, organs to be inadequately perfused, and eventually, multiple organ failure, which is often lethal. Gram - positive bacteria, although producing harmful exotoxins, do not typically induce such a severe systemic response associated with septic shock as often as gram - negative bacteria.
