ok what if they have that person on antibiotics, and then the infection occured?

Answer 1

Before even trying to give a patient a certain antibiotic some laboratory tests should be done first like Culture and Sensitivity test where we will find out what kind of bacteria is present in the body and what anitbiotics will react to it. Now, if the person still gets the infection, we will have to try the next generation antibiotic..means we will have to get a stronger antibiotic because probably the bacteria got immuned with the first one. If still..it did not react, the last option is the third generation antibiotic (which SHOULD NOT be given unless the bacteria is really non-reactant to the first & second generation antibiotics) which is the strongest one. Doctors are given strict rules that they should not just give any antibiotic to patients if not sure of what the main problem is because the more we introduce a wrong antibiotic to a patient, the more immune the bacteria will become and this can kill a patient. Hope this helps. God bless

Answer 2

Antibiotics are formulated to target specific organisms. Antibiotic X works on bacteria A & B but not C. Any bacterium not sensitive to that antibiotic or any bacterium resistant to that antibiotic can cause a concurrent infection. Does this make it clearer for you?

The person above stated that you can become "immune" to an antibiotic. Not true. What happens is bacterial mutation that results in resistance to the antibiotic.

Answer 3

Different antibiotics work on different things. Say you were on antibiotics for an ear infection and while on them you came in contact with strep throat. The medication for the ear infection would not prevent you from getting strep throat because the antibiotic for one does not work for the other.

Also, if you have had an antibiotic many times over your life time, you can become immune to its effects. Either way, it could cause you to still get sick while on medication.

Answer 4

Then why would you be on that antibiotics anyways?
