Answer #1

ANSWER: The slope of the exponential curve of a tetracycline resistant bacteria in the presence of tetracycline will decrease since the overall growth of bacteria will slow down.

The plasmid contains the gene for resistance and in the presence of antibiotic for which it is resistant, the bacteria has to express more resistance gene to maintain its resistance, for which it needs energy. The energy is thus diverted towards maintaining resistance and this will lead to overall decrease in the growth of bacteria.

Bacteria are the most common cause of sepsis, with 62.2% of patients with positive blood cultures harboring Gram-negative bacteria and 46.8% infected with Gram-positive bacteria. This overlap can be explained by polymicrobial sepsis, which is frequently simulated in mouse models. While Escherichia coli can be found in approximately 1 in 6 culture-positive patients, Gram-positive bacteria such as methicillin-resistant Staphylococcus aureus (MRSA) have made up an increasing percentage of sepsis with the advent of excessive antibiotic treatment. Now, you collected blood...
