Results from a Kirby Bauer antibiotic assay on a Gram-negative bacterial culture are described as follows: A) the bacterium is resistant to penicillin, an antibiotic that targets synthesis of the peptidoglycan cell wall and B) the bacterium is resistant to tetracycline, an antibiotic that targets the small subunit of the ribosome, inhibiting protein synthesis. Which of the results represents intrinsic resistant and which represents acquired resistants?
What does it mean to say that a cell is “competent” and how is this relevant to natural bacterial transformations?
The ribosome is the target for many important antibiotics. These drugs must discriminate between bacterial and eukaryotic ribosomes to achieve drug specificity and toxicity. For the two common antibiotics below, what is their mechanism of action and why are they more toxic to bacteria than eukaryotes?
a) Tetracycline
b) Erythromycin

- How can i explain my answers in depth in microbology for example this question: Assume that there are horizontal gene transfers between two completely different bacterial species.
