What are the 5 classes of antibiotics?
In this portal, antibiotics are classified into one of the following classes: penicillins, fluoroquinolones, cephalosporins, macrolides, beta-lactams with increased activity (e.g. amoxicillin-clavulanate), tetracyclines, trimethoprim-sulfamethoxazole, lincosamides (e.g. clindamycin), urinary anti-infectives, and other
What is streptomycin used for?
STREPTOMYCIN (strep toe MYE sin) is an aminoglycoside antibiotic. It is used to treat certain kinds of bacterial infections. It will not work for colds, flu, or other viral infections.
Is streptomycin a narrow spectrum antibiotic?
This eventually leads to bacterial cell death. Streptomycin is a broad spectrum aminoglycoside antibiotic typically used for treatment of active tuberculosis, always in combination with other antituberculosis agents.
Is streptomycin a penicillin?
Penicillin is a beta-lactam antibiotic derived from Penicillium fungi. Streptomycin is an aminoglycoside antibiotic produced by Streptomyces. It binds to the 30S subunit of the bacterial 70S ribosome and blocks the initiation complex of protein synthesis.
What are the 7 main classes of antibiotics?
7 Types of Antibiotics
- Penicillins such as penicillin and amoxicillin.
- Cephalosporins such as cephalexin (Keflex)
- Macrolides such as erythromycin (E-Mycin), clarithromycin (Biaxin), and azithromycin (Zithromax)
- Fluoroquinolones such as ciprofolxacin (Cipro), levofloxacin (Levaquin), and ofloxacin (Floxin)
What are the two major classes of antibiotics?
Antibiotics can be divided into two classes based on their mechanism of action. Bactericidal antibiotics kill bacteria; bacteriostatic antibiotics inhibit their growth or reproduction.
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.
Why streptomycin is no longer used?
Streptomycin was the first effective antituberculosis drug but is no longer a first-line drug as it has the disadvantage that it is not absorbed from the intestine and must therefore be given by intramuscular injection.
Why is it better to use narrow-spectrum antibiotics?
Advantages. Narrow – spectrum antibiotic allow to kill or inhibit only those bacteria species that are unwanted (i.e. causing disease). As such, it leaves most of the beneficial bacteria unaffected, hence minimizing the collateral damage on the microbiota. Low propensity for bacterial resistance development.
Is Penicillin a narrow-spectrum antibiotic?
Examples of narrow – spectrum antibiotics are the older penicillins (penG), the macrolides and vancomycin. Examples of broad – spectrum antibiotics are the aminoglycosides, the 2nd and 3rd generation cephalosporins, the quinolones and some synthetic penicillins.
What bacteria does streptomycin target?
Streptomycin is the first discovered aminoglycoside antibiotic, originally isolated from the bacteria Streptomyces griseus. It is now primarily used as part of the multi-drug treatment of pulmonary tuberculosis. It has additional activity against several aerobic gram-negative bacteria.
Can streptomycin be given orally?
25% Streptomycin Sulfate Oral Veterinary Solution Each ml contains 250 mg. streptomycin (as sulfate). STREPTOMYCIN ORAL SOLUTION is indicated as an aid in the treatment of certain enteric diseases in which streptomycin -sensitive coliform bacteria (Escherichia, Salmonella, Vibrio, etc.)
Is streptomycin still used today?
Streptomycin was discovered in 1943. It was the first antibiotic discovered that was effective against TB. Today it is widely used as a first line TB medicine in patients that have previously been treated for TB.
Why is streptomycin so effective?
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. Over time, bacteria have become resistant to streptomycin.
