0 Comments

Which antibiotic is more effective against Staphylococcus aureus quizlet?

Which antibiotics were effective against S. aureus? Penicillin and tetracycline were most effective.

Which antibiotics were effective against E coli?

Tetracycline was the most effective true antibiotic tested against E. coli.

Which antibiotics were most effective against MRSA quizlet?

In conclusion, the most effective antibiotics in S. aureus strains were identified as vancomycin, linezolid, levofloxacin, and daptomycin. Surveillance studies need to be carried out periodically in every hospital to engage in an effective fight against MRSA -based hospital infections and to reduce resistance rates.

Which antibiotic was not effective against E coli quizlet?

The streptomycin antibiotic is not effective on E. coli I as it is resistant to it, so it continued growing on the agar plate. It was not resistant to ampicillin, so the ampicillin destroyed the bacteria.

Which two antibiotics were most effective against S aureus?

The antibiotics most effective against all S aureus cultures for outpatients were linezolid (100%), trimethoprim sulfamethoxazole (95%) and tetracyclines (94%). Linezolid (100%), trimethoprim sulfamethoxazole (100%) were most effective against MRSA isolates.

How can you tell how effective an antibiotic is against a bacteria just by looking at the petri dish?

Here, traditional diagnostic techniques, such as the disk-diffusion test (see video below), will look at the growth of bacteria in the sample in the presence of antibiotics. An antibiotic is considered effective at treating the infection if it stops bacteria multiplying on the petri dish on which it has been cultured.

Is amoxicillin effective against E coli?

Amoxicillin is effective against many different bacteria including H. influenzae, N. gonorrhoea, E. coli, Pneumococci, Streptococci, and certain strains of Staphylococci.

What is the best antibiotic for E coli UTI?

Drugs commonly recommended for simple UTIs include:

  • Trimethoprim/sulfamethoxazole (Bactrim, Septra, others)
  • Fosfomycin (Monurol)
  • Nitrofurantoin (Macrodantin, Macrobid)
  • Cephalexin (Keflex)
  • Ceftriaxone.

What is the most effective treatment for E coli?

coli infections, usually bladder or other urinary tract infections, are treated with antibiotics, such as trimethoprim/sulfamethoxazole, nitrofurantoin, or a fluoroquinolone. However, many bacteria, particularly those acquired in a health care facility, are resistant to some antibiotics.

What difference in antibiotic sensitivity did you observe between S aureus and MRSA?

aureus and MRSA A. There were no differences between the effectiveness of the antibiotics on the two types of bacteria. The antibiotic that was most effective against S. aureus was not effective against MRSA.

Which answer choice does not contain at least one cellular process inhibited by antibiotics quizlet?

Answer: C. Eukaryotic protein synthesis and eukaryotic cell wall synthesis are not inhibited by antibiotics.

Which structure did you see in the eukaryotic cells that is absent in the prokaryotes quizlet?

Eukaryotic cells contain a membrane-bound nucleus and numerous membrane-enclosed organelles (e.g., mitochondria, lysosomes, Golgi apparatus) not found in prokaryotes.

What antibiotic would you prescribe Sue Why?

For sue I can also prescribe sulfa drugs class of antibiotics, also referred to as sulfonamide. These antibiotics are synthetic antibiotics and contain the sulfanilamide molecular structure. Sulfa drugs are used to treat and prevent bacterial infections in humans. So the bacteria by Sue is Gama negative.

Why is penicillin effective at killing bacteria quizlet?

Penicillin is effective against bacteria because it prevents the bacterium from forming a cell wall once it has divided. Because human cells do not contain a cell wall, penicillin does not target the proteins that help make up the cell wall. Therefore, antibiotics do not kill human cells.

Which type of bacteria are typically more difficult to treat using antibiotics?

Enterobacteriaceae, such as Klebsiella pneumoniae and Escherichia coli (E. coli) can cause serious infections of the urinary tract, bloodstream and wounds, and can also cause pneumonia. These infections are becoming difficult to treat because some bacteria have become resistant to all or most available antibiotics.
