What is an important example of an antibiotic bacteria?
Important examples are: methicillin-resistant Staphylococcus aureus (MRSA) vancomycin-resistant Enterococcus (VRE) multi-drug-resistant Mycobacterium tuberculosis (MDR-TB)
How do antibiotics work against bacteria explain giving an example?
Antibiotics work by blocking vital processes in bacteria, killing the bacteria or stopping them from multiplying. This helps the body’s natural immune system to fight the bacterial infection. Different antibiotics work against different types of bacteria.
What are antibiotics How are they produced give two examples?
Antibiotics are chemicals that kill or inhibit the growth of bacteria and are used to treat bacterial infections. They are produced in nature by soil bacteria and fungi.
What is an antibiotic give 2 example?
Antibiotic is a chemical secreted by microorganisms (bacteria or fungi) that kills or hinders the growth of some kinds of bacteria. Examples. Penicillin and streptomycin.
What are the different classes of Antibiotics?
Classes of antibiotics include the following:
- Aminoglycosides.
- Carbapenems.
- Cephalosporins.
- Fluoroquinolones.
- Glycopeptides and lipoglycopeptides.
- Macrolides.
Which of the following processes in bacteria can be interrupted by antibiotics?
Depending on these effects an antibiotic is said to be bactericidal or bacteriostatic….Selected Resources.

What are the different antibiotics?
The main types of antibiotics include:
- Penicillins – for example, phenoxymethylpenicillin, flucloxacillin and amoxicillin.
- Cephalosporins – for example, cefaclor, cefadroxil and cefalexin.
- Tetracyclines – for example, tetracycline, doxycycline and lymecycline.
- Aminoglycosides – for example, gentamicin and tobramycin.
What are antibiotics give examples Class 8?
Antibiotics are the drugs that are used to cure diseases caused by bacteria. Antibiotic stops the production of a compound needed for the growth of the cell wall of bacteria. This prevents the cell wall from expanding when the other parts of the cell are growing. Examples, Penicillin and Streptomycin.
How to investigate the effect of different antibiotics on bacteria?
To investigate the effect of different antibiotics on bacteria. Type and amount of bacteria used – E.coli will be used as the bacteria and it will be evenly spread across an agar medium Volume of antibiotic used for each disc – mast ring will be used with equal concentrations of each antibiotic
Which bacteria will be used as the bacteria in the agar?
Type and amount of bacteria used – E.coli will be used as the bacteria and it will be evenly spread across an agar medium Volume of antibiotic used for each disc – mast ring will be used with equal concentrations of each antibiotic
What is the hypothesis of antibiotics?
Experimental Hypothesis- Increasing the antibiotic concentration decreases bacterial growth.Scientific TheoryBacteria are prokaryotes and can be identified by their shape. Spherical bacteria are called cocci, rod shaped bacteria are called bacilli, spiral shaped bacteria are called spirilla and curved shape bacteria are called vibrio.
Why do antibiotics become less effective over time?
Each time you take antibiotics, you are more likely to have some bacteria that the medicine does not kill. Over time these bacteria change (mutate) and become harder to kill. The antibiotics that used to kill them no longer work. These bacteria are called antibiotic-resistant bacteria.
