Which of the following inhibits protein synthesis?

Which of the following inhibits protein synthesis?

Chloramphenicol prevents protein synthesis over.

Which antibiotics inhibit protein synthesis select all that apply?

Aminoglycosides and tetracyclines are inhibitors of protein synthesis. Penicillins and cephalosporins inhibit nucleic acid synthesis.

Which drugs inhibit bacterial cell wall synthesis?

A number of drugs inhibit cell wall synthesis. Most important are vancomycin, which targets monomer polymerization; and the β-lactams, e.g., penicillins and cephalosporins, which block polymer cross-linking. β-lactam antibacterial agents also activate autolysins.

Why are some drugs that inhibit protein synthesis in bacteria also harmful to humans?

Why are some drugs that inhibit protein synthesis in bacteria also harmful to humans? Eukaryotic mitochondria have 70S ribosomes. Humans and bacteria have very similar types of ribosomes. Some human cells have mutated ribosomes, which are more susceptible to these drugs.

How does resistance to drugs spread in bacterial populations?

How does resistance to drugs spread in bacterial populations? Horizontal gene transfer between bacteria spreads R (resistance) plasmids. c. Both horizontal gene transfer and the growth of biofilms spread drug resistance.

How do humans contribute to antibiotic resistance?

Prevention and control. Antibiotic resistance is accelerated by the misuse and overuse of antibiotics, as well as poor infection prevention and control.

What are the 6 factors contributing to antibiotic resistance?

Overuse of antibiotics in livestock and fish farming. Poor infection control in health care settings. Poor hygiene and sanitation. Absence of new antibiotics being discovered.

Why do we find a lot of resistant bacteria in hospitals?

Patients in these facilities are commonly exposed to antibiotics and receive lots of hands on care. Additionally, most resistant germs are more common in hospitals than in the community. These are factors which can lead to spread of resistant germs.

What are 3 common examples of nosocomial infections?

Some well known nosocomial infections include: ventilator-associated pneumonia, Methicillin resistant Staphylococcus aureus, Candida albicans, Acinetobacter baumannii, Clostridium difficile, Tuberculosis, Urinary tract infection, Vancomycin-resistant Enterococcus and Legionnaires’ disease.

What is the most common type of hospital?

Most US hospitals are classified as community hospitals according to the American Hospital Association. Two-thirds are located in large cities. Some community hospitals provide general care, and others focus on certain diseases and conditions, such as orthopedics, to provide specialty care.

What are the different ways in which infectious diseases can spread?

Infectious diseases can spread in a variety of ways: through the air, from direct or indirect contact with another person, soiled objects, skin or mucous membrane, saliva, urine, blood and body secretions, through sexual contact, and through contaminated food and water.

What kind of diseases can antibiotics cure?

Antibiotics can treat bacterial infections, such as:

  • Most sinus infections.
  • Strep throat.
  • Urinary tract infections.
  • Pneumonia.
  • Most ear infections (otitis media)
  • Nasty bacterial skin infections (impetigo)

What are two differences between bacteria and viruses?

Bacteria are single-celled, living organisms. They have a cell wall and all the components necessary to survive and reproduce, although some may derive energy from other sources. Viruses are not considered to be “living” because they require a host cell to survive long-term, for energy, and to reproduce.
