What are antibiotics effective at treating?
Antibiotics are used to treat or prevent some types of bacterial infection. They work by killing bacteria or preventing them from reproducing and spreading. Antibiotics aren't effective against viral infections, such as the common cold, flu, most coughs and sore throats.

The efficacy of antimicrobials are influenced by many factors: (1) bacterial status (susceptibility and resistance, tolerance, persistence, biofilm) and inoculum size; (2) antimicrobial concentrations [mutant selection window (MSW) and sub-inhibitory concentration]; (3) host factors (serum effect and impact on gut ...
Are antibiotics effective in preventing or treating Covid give reason for your answer?
No. According to the World Health Organization, antibiotics do not work against viruses. They only work on bacterial infections. COVID-19 is caused by a virus, so antibiotics do not work.
How do you ensure the best use of antibiotics and minimal harm?
choose the right dose, duration, and route for the condition you are treating. cause the least amount of harm for the patient - consider drug interactions, allergy and toxicity. cause the least amount of harm to future patients by increasing antimicrobial drug resistance.
Antibiotics
The word antibiotic comes from the Greek anti meaning ‘against’ and bios meaning ‘life’ (a bacterium is a life form).’ Antibiotics are also known as antibacterials, and they are drugs used to treat infections caused by bacteria. Bacteria are tiny organisms that can sometimes cause illness to humans and animals.
Bacteria
The word bacteria is the plural of bacterium. Grammatically the headline should just say “What are bacteria?” The incorrect usage has been included in the headline to remind readers that it is wrong – and hopefully help correct an increasingly common mistake in the English language.
MATERIALS
Petri dish, sample of E.coli and staphylococcus, 3 different types of antibiotic which are carbenicilin, streptomycin and tetracycline, distilled water, Dettol handwash, 75 % of ethanol, agar, tissue paper
HYPOTHESIS
The most effective antibiotic to inhibit bacteria growth is ampicillin
PROCEDURE
First of all, wash out hands with the soap or handwash. The working area is sprayed thoroughly with the disinfectant spray. It is left for at least 10 minutes, and wiped with a paper towel.
PRECAUTIONS
When carrying out the experiment, we should work very closed to the Bunsen burner to prevent any impurities in each apparatus that is used.

How do antibiotics fight infections?
Antibiotics are medicines that fight infections caused by bacteria in humans and animals by either killing the bacteria or making it difficult for the bacteria to grow and multiply. Bacteria are germs. They live in the environment and all over the inside and outside of our bodies.
Why are antibiotics important?
Antibiotics are important to treat infections and have saved countless lives. However, anytime antibiotics are used, they can cause side effects and contribute to antibiotic resistance, one of the most urgent threats to the public’s health.
When to use antibiotics when sick?
It’s important to use antibiotics only when they are needed to protect yourself from harms caused by unnecessary antibiotic use and combat antibiotic resistance.
Why are antibiotics needed for urinary tract infections?
Urinary tract infection (UTI) Antibiotics are also needed to treat life-threatening conditions caused by bacteria, such as sepsis, which is the body’s extreme response to infection.

Procedure
- First of all, wash out hands with the soap or handwash. The working area is sprayed thoroughly with the disinfectant spray. It is left for at least 10 minutes, and wiped with a paper towel. An agar plate seeded with is prepared. The petri dish is labeled on the base at the edge out of name, the date and type of bacterium it is inoculated with by usng permanent marker pen. After finishing …

- Make sure our hands are constantly being wash with disinfectant before touching any apparatus.
Limitations
- There are some limitations that cannot be avoided when carrying out the experiment. The first one was every apparatus that we used had been sterile by the laboratory assistant. Thus we had to wash our hands thoroughly before touching anything. We even could not talk during the preparation. The problem was we carried out the experiment on the lab’s table, instead of using t…
Sources of Error
- There are some sources of error when carrying out this experiment. Firstly, we prepared the experiment at room temperature. It was supposed to carry out in sterile medium to prevent anything from affecting during the preparation of bacteria and antibiotics. Next, the major problem that could be seen during the experiment was most of the groups could not be able to s…
Further Work
- To get more reliable and accurate result, this experiment should be repeated by varying the temperature to investigate the activity of antibiotic on bacteria. This means that increase the temperature would cause the antibiotic to act more rapidly compared to the temperature that we used before. Thus we do not have to wait for 24 hours to see the inhibition zone. This manipulat…
