Antibiotics can only kill bacteria. Not fungi or viruses.
biology
MIC - Minimum Inhibitory Concentration is the lowest concentration of an antibiotic needed to stop the microbe from reproducing.MBC - Minimum Biocidal Concentration is the lowest concentration of an antibiotic needed to kill the microbe.
If you overuse it then when you really need it, it won't work. The reason is that your doctor should do a culture, like a throat swab, and run a sensitivity test to see if an antibiotic is needed and which one will affect the microbe. You want to hit the microbe with accuracy and not with a "shot-gun". When treating the microbe with the right drug, the persons' normal flora will not become resistant to that antibiotic. I get really upset if a culture and sensitivity isn't done because the antibiotic may be needed to knock a microbe out and now it will not work at all or have to be given higher doses.
The microbe is virus
The common cold is caused by a VIRUS not a microbe (a microbe is a bacteria).
Microbes that are susceptible to a particular antimicrobial agent are those that can be effectively controlled or killed by that agent. Susceptibility testing is conducted to determine which antimicrobials are effective against specific microbes, aiding in treatment selection. It helps guide clinicians in choosing the most appropriate antibiotic to target the microbial infection.
If a microbe is not affected by antibiotics, it is said to be resistant to the antibiotic.
Viruses are microscopic and can not be killed by antibiotics (against life) as they are not living.
It is a term for antibiotics. An ultra broad range antibiotic can be used against many no. of microbes not a particular microbe. Meropenem is an ultra broad spectrum antibiotic.
Minimum inhibitory concentration, a measure of how well an antibiotic does at controlling a certain microbe.
The type of microbe which causes Malaria is Protozoa... well that's what i was told by my science teacher :) x
Bacteria.
