People get sick from many different types of organisms. Anitbiotics provide effective treatments for most bacterial infections. However, we may get sick from parasites, viruses and/or fungi. Antibiotics won't necessarily be effective at curing these other types of infections.
Several reasons, but most likely is either (1) not a bacterial infection, (2) wrong antibiotics given, or (very unlikely) (3) bacteria infection from antibiotic resistant species. Of course all of this is presumed with the understanding of taking the antibiotic as recommended, and taking it all.
Antibiotics only kill bacteria. If your disease is not caused by bacteria, the antibiotic will have no effect.

the use of antibiotics to prevent infections
Sick ones.
The use of antibiotics and pesticides.
One thing is that antibiotics cannot kill viruses, as viruses are DNA structures which enter the cells in your body in order to duplicate, however antibiotics cannot enter into the cells, and can therefore not stop the virus.
The effect of the decision to use antibiotics is that you will use antibiotics.
Antibiotics are used. The original kinds, and still some in use today, were purified from secretions by certain fungi, which protected themselves against bacteria this way. Today there are many kinds of antibiotics, for various applications, and most of them are synthetically produced in laboratories. They are molecular miracles.
antibiotics are really essential for treatment but some antibiotics cause side effects can be of any type it may be terotogenic which means you should not be given in pregnancy there are so many other type of allergic reactions are associated with antibiotics but it is necessary to give antibiotics
Now, they use antibiotics. Then, they didn't have one.
To kill or sometimes prevent an infection that could be harmful to their health.
Well, antibiotics can defend against bacteria some parasites and some fungi. They can't immunise your body against viruses because they evolve too quickly. That's why there is no antibiotics for the common cold. Also, if you use too many antibiotics, the cells you are trying to defend against will effectively get used to the antibiotics and will find a way to defeat them. The antibiotics will be useless.
demerit of antibiotics
Antibiotics kill the bacteria but not the people by affecting parts of the bacterial system that humans do not share. Viruses use the person's own systems to do most functions and so not have the same or as many targets for the drugs. There are some antiviral drugs but now as many as antibiotics.
