Bronchitis Treatment

If an antibiotic is increased in concentration then would the effect on the bacteria be increased?

When testing the effect of an antibiotic on bacteria can it be said that to be sensitive to an antibiotic, the antibiotic must be of a large enough dose to have an effect on it. This is measured by the diameters of the growth inhibition zones. Would an increased dosage increase the sensitivity of the antibiotic to the bacterium and basically be able to kill it quicker?

Answer 1:

It's not about speed.
If you're talking using antibiotic discs on an plate of agar innoculated with bacteria, the reason that the region of inhibition is larger for the higher concentrations is a simple case of diffusion.

Antibiotics, like most chemicals, will diffuse - moving from an area of high concentration (the disc) to an area of low concentration.

As you say, the concentration of the antibiotic needs to be at a large enough dose to be effected. So...the higher the initial concentration on the disc, the larger the area of diffusion of the antibiotic, within which it's concentration is still high enough to effectively kill the bacteria and prevent growth.

Hope that makes sense.

Answer 2:

When you are dealing with an antibiotic you have to consider side effects. You want the medication to work and kill off the bacteria, but not wipe out all of the bacteria in the intestinal track.You will then wind up with increased side effects mostly nausea & vomiting, as well as diarrhea.The other consideration is overgrowth of non susceptible organisms when you increase any concentration.

A doctor will give you an antibiotic to treat a bacterial infection, but you are given a vaccine to keep a vi?

A doctor will give you an antibiotic to treat a bacterial infection, but you are given a vaccine to keep a virus (and some bacteria) from making you ill. What is the difference between these approaches?

Answer 1:

the antibiotic is to treat a bacteria. A vaccine is to prevent certain diseases / viruses

What is the difference between an antibiotic and antiseptic?

What is the difference between an antibiotic and antiseptic? Give an example of each and describe how each is used may be related to its potency.

I know the difference and examples, but what is the question asking when it says "describe how each is used may be related to its potency."

Answer 1:

I think they're asking how different methods of applying different medicines can affect how effectively they work ...

Example, Oral ingestion (tablets/pills/liquid-preparations) have to go through the digestive system before the active components can enter the blood-stream and may not therefore be as effective as if the same medicine were prepared and administered intravenously (injection).

Many medicines are available in different forms for people that can't take pills, can't have any creams applied to their skin, can't have injections (eg. blood-clotting problems) etc' ... Perhaps they want a synopsis of the effectiveness for the different methods of administering specifically anti-biotic and anti-bacterial preparations.

Answer 2:

I think antiseptics are more potent since they are only used externally, they easily irritate tissues, and they kill the bacteria whereas antibiotics are used internally and usually prevent reproduction of the bacteria.
wow.. you copied the question word for word from the lab..

How long should someone be off of an antibiotic before getting a culture?

I know that culture results (blood, urine, sputum) can be false negative if acquired while someone is taking an antibiotic. But how long should someone be off the antibiotic before a culture will be accurate?

Answer 1:

at least a week.
