Antibiotics are essential for treating bacterial infections, and streptomycin and gentamicin are both commonly used antibiotics. However, there are some key differences between these two antibiotics that are important for healthcare professionals and patients to be aware of.
In this blog, we will explore the differences between streptomycin and gentamicin, and explain why understanding these distinctions is important.
Mechanism of action
Streptomycin and gentamicin are both antibiotics belonging to the aminoglycoside class. They have similar mechanisms of action, which involve blocking the production of essential proteins, hindering bacterial growth and ultimately leading to cell death. However, they differ in certain respects.
Streptomycin is more effective against aerobic bacteria, while gentamicin is more effective against anaerobic bacteria. Furthermore, gentamicin is known to be more toxic to humans and typically requires careful monitoring to ensure proper dosages are taken.
Ultimately, the choice of which antibiotic to use depends on the type of infection and the health of the patient.
Side effects
The main difference between streptomycin and gentamicin lies in their respective side effects. Streptomycin is associated with more severe side effects like dizziness, nausea, vomiting, and hearing loss, while gentamicin is generally considered to be safer with fewer side effects. However, gentamicin can still cause irritation and inflammation in the eyes, ears, and skin.

Uses and benefits
Streptomycin and gentamicin are both antibiotics used to treat bacterial infections. They are both derived from a soil bacteria, Streptomyces, which produces the antibiotics. The major difference between the two is that streptomycin is a bactericidal antibiotic, meaning it kills bacteria, while gentamicin is a bacteriostatic antibiotic, meaning it stops bacteria from reproducing and growing.
Streptomycin is more effective against aerobic bacteria (bacteria that require oxygen to survive) and is used to treat tuberculosis, plague, and certain types of pneumonia. Gentamicin, on the other hand, is more effective against anaerobic bacteria (bacteria that do not require oxygen to survive).
It is used to treat a variety of bacterial infections, such as urinary tract infections, bone and joint infections, and certain types of skin infections. In general, gentamicin is a better choice for treating anaerobic bacteria, while streptomycin is better for treating aerobic bacteria.
Availability and cost
The two antibiotics streptomycin and gentamicin are both used to treat bacterial infections, but there are some key differences between them. Streptomycin is generally seen as the more affordable option, as it is typically available in generic form and at a lower cost than gentamicin. However, gentamicin is usually more effective in treating certain types of bacteria, such as pseudomonas aeruginosa, and may be used in more serious cases of infection.
However, gentamicin is usually more effective in treating certain types of bacteria, such as pseudomonas aeruginosa, and may be used in more serious cases of infection. Each of these antibiotics has its own advantages and disadvantages, so it is important to discuss the cost and effectiveness with a doctor before deciding which one to use.
Streptomycin vs gentamicin: what’s the difference
Streptomycin and gentamicin are both antibiotics that are used to treat a wide variety of bacterial infections, but there are some distinct differences between them. Streptomycin is an aminoglycoside antibiotic that works by disrupting the protein synthesis of bacteria, while gentamicin is a broad-spectrum antibiotic that works by inhibiting the growth of bacteria.
Streptomycin is typically more effective against Gram-positive bacteria, while gentamicin is more effective against Gram-negative bacteria. Additionally, streptomycin is more likely to cause nephrotoxicity and ototoxicity, while gentamicin is more likely to cause neurotoxicity. Therefore, it is important to understand the differences between these two antibiotics before deciding which one to use.
Bottom Line
The major difference between streptomycin and gentamicin is that streptomycin is a broad-spectrum antibiotic that works against a wide range of gram-positive and gram-negative bacteria whereas gentamicin is a narrow-spectrum antibiotic that works only against gram-negative bacteria. Both antibiotics are effective against several infectious diseases, including tuberculosis, endocarditis, and meningitis.
In general, gentamicin is used more often than streptomycin because it is more potent and has fewer side effects.
