Why do we combine antibiotics?

Combination therapy is mostly practiced because of one or more of the following reasons: Broadening antibacterial spectrum. Use of more than one agent broadens the antibacterial spectrum of the empirical therapy and thus ensures that at least one agent will cover the infecting organism.

How do the progeny of an antibiotic sensitive bacteria become resistant quizlet?

How can a specimen acquire resistance? – Spontaneous or induced genetic mutation. – Many antibiotic resistance genes reside on transmissible plasmids. VT: occurs when genes are passed from an organism to its offspring.

Are antibiotics becoming useless and obsolete?

By 2050, 10 million people could die each year from diseases that have grown resistant to drugs. “Common diseases are becoming untreatable.” That’s the blunt warning issued on page one of a major new United Nations report on drug resistance.

How can we prevent antibiotic resistance?

There are many ways that drug- resistant infections can be prevented: immunization, safe food preparation, handwashing, and using antibiotics as directed and only when necessary. In addition, preventing infections also prevents the spread of resistant bacteria.

Is phage therapy better than antibiotics?

Phages won’t harm any of your cells except for the bacterial cells that they’re meant to kill. Phage therapy has fewer side effects than antibiotics. On the other hand, most antibiotics have a much wider host range. Some antibiotics can kill a wide range of bacterial species at the same time.

Why is phage therapy not used?

Phage therapy disadvantages Additionally, it’s not known if phage therapy may trigger bacteria to become stronger than the bacteriophage, resulting in phage resistance. Cons of phage therapy include the following: Phages are currently difficult to prepare for use in people and animals.

Do antimicrobials work on viruses?

Antimicrobial products kill or slow the spread of microorganisms. Microorganisms include bacteria, viruses, protozoans, and fungi such as mold and mildew. You may find antimicrobial products in your home, workplace, or school.

  • Cephalosporins.
  • Aminoglycosides.
  • Tetracyclines.
  • Macrolides.
  • Fluoroquinolones.

Why do antibiotics not work against viruses quizlet?

Viruses are not living and reproduce using their host cell’s metabolic pathways. Antibiotics do not affect the host cell’s metabolic processes and so the antibiotics are not effective against viruses.

What is most likely the reason why the fungus is killing the bacteria quizlet?

What seem to be the most likely reason the bacteria is being killed by the fungal growth? The fungus produces an antibacterial compound. The fungal compound reduces bacterial growth.

Why do you think penicillin has failed to destroy the bacteria we have cultured from the patient sample quizlet?

Why do you think penicillin has failed to destroy the bacteria we have cultured from the patient’s sample? Perhaps a few cells from the old infestion developed resistance and so weren’t cleared by the previous treatment. By blocking the enzyme responsible, penicillin stops the bacteria from producing new peptidoglycan.
