Streptomycin is a member of a family of antibiotics that work
by interrupting the function of bacteria cells’ ribosomes
, the complex molecular machines that create proteins by linking amino acids together.
Which mechanism of action does streptomycin use to kill bacteria?
Streptomycin kills bacteria
by compromising the ribosome
. Streptomycin is an effective antibiotic because its structure is similar to that of the anticodons that would usually bind to the ribosome. Streptomycin is significant because it was the first antibiotic that could treat tuberculosis.
How does streptomycin perform its antibiotic function?
Streptomycin is a member of a family of antibiotics that work
by interrupting the function of bacteria cells’ ribosomes
, the complex molecular machines that create proteins by linking amino acids together. … This results in the synthesis of random proteins, which ultimately kills the bacteria.
How do penicillin and streptomycin kill bacteria?
Penicillin kills bacteria
through binding of the beta-lactam ring to DD-transpeptidase
, inhibiting its cross-linking activity and preventing new cell wall formation.
How does streptomycin not kill human cells?
Antibiotics are simply chemicals that kill prokaryotic cells
Why is streptomycin not used?
A history of
clinically significant hypersensitivity to streptomycin
is a contraindication to its use. Clinically significant hypersensitivity to other aminoglycosides may contraindicate the use of streptomycin because of the known cross-sensitivity of patients to drugs in this class.
What is the most serious toxic effect of streptomycin?
Streptomycin injection is usually used for serious bacterial infections for which other medicines may not work. However, it may also cause some serious side effects, including
damage to your hearing and sense of balance
. These side effects may be more likely to occur in elderly patients and newborn infants.
What is the strongest antibiotic for bacterial infection?
The world’s last line of defense against disease-causing bacteria just got a new warrior:
vancomycin 3.0
. Its predecessor—vancomycin 1.0—has been used since 1958 to combat dangerous infections like methicillin-resistant Staphylococcus aureus.
What bacteria is resistant to streptomycin?
More recently, mutations in rRNA genes have been found to be associated with in vivo acquired drug resistance in bacterial pathogens, e.g., in
Mycobacterium tuberculosis
resistant to streptomycin (10); most of the mutations found mapped to the 530 region of 16S rRNA (15, 27).
Why is penicillin useless against a virus?
Antibiotics cannot kill viruses because bacteria and viruses have different mechanisms and machinery to survive and replicate. The
antibiotic has no “target” to attack in a virus
. However, antiviral medications
Will streptomycin kill bacteria?
Streptomycin
kills bacteria by compromising the ribosome
. Streptomycin is an effective antibiotic because its structure is similar to that of the anticodons that would usually bind to the ribosome.
Do antibiotics kill human cells?
Antibiotics are substances that
kill bacteria
without harming the cells of your body.
Why do antibiotics kills bacteria cells and not human cells?
Official Answer. Antibiotics
work by interfering with the bacterial cell wall to prevent growth and replication of the bacteria
. Human cells do not have cell walls, but many types of bacteria do, and so antibiotics can target bacteria without harming human cells.
Who should not take streptomycin?
The risk is higher if you have
kidney disease
, if you are receiving high doses of this medication, if you use this drug for a long time, if you are an older adult (older than 60 years), or if you develop a severe loss of body water (become dehydrated).
Is streptomycin safe to use?
Streptomycin may cause nerve damage or hearing loss, especially if you have kidney disease or use certain other medicines. Tell your doctor right away if you have severe dizziness, hearing problems, vision problems, balance problems, trouble concentrating, muscle weakness, numbness, or tingling.
What is the side effect of streptomycin?
Nausea, vomiting, stomach upset, or loss of appetite may occur
. Pain/irritation/redness may occur at the injection site. If any of these effects persist or worsen, tell your doctor or pharmacist promptly.
