The effectiveness of antibiotics has diminished because they have been used so much the infections that they used to be so effective against have adapted so that they are resistant or even immune to the antibiotic.
By using any antibiotic, you are actually selecting for organisms that are resistant to the antibiotic. There usually a few microbes in every group that have genes that make them resistant. Just as humans have various genes, so do microbes.
Antibiotics should ONLY be used when necessary and not for every sniffle. Many times your doctor will give an antibiotic when what you have is caused by a virus. Viruses are not affected in anyway by antibiotics.

What antibiotic potency means?
how effective it is.
A or An WHAT TYPE of DRUG is effective against a wide range of pathogens?
This would be called a broad-spectrum antibiotic.
How safe are antibiotic drugs?
depends on which antibiotic you are using. For example, Azithromycin is a relatively safe and effective antibiotic. Where as Vancomycin, is a highly effective antibiotic (covers MRSA) but has a lot of morbidities associated w/ it (hearing loss, kidney malfunction, etc).
What antibiotic is given for salmonella?
They can treat salmonella, but you generally don't take any for food poisoning, as it doesn't help clinically, and can even make it last longer, as you take longer to excrete the bug. If you're really sick, or have it in your blood, or young, though, it is given for safety Azithromycin is an effective antibiotic.
Why should antibiotics not be excess used?
If an antibiotic is used excessively, it may destroy too many of the harmless and helpful microbes in the body, and it may result in the development of a strain of harmful microbes resistant to the antibiotic so that it will no longer be effective in killing them.
What antibiotic is effective against chickenpox?
none, that is a virus
What is Antibiotic Sensitivity?
Antibiotic sensitivity is an evaluation of how effective a given antibiotic is at killing the pathogen that grew in culture. When antibiotic resistance is a problem the sensitivity study helps clinicians choose the right medication.
What is effective at treating strep throat but not at treating the flu?
An antibiotic.
The zones on inhibition for two antibiotic a and b on a sarcina lutea dish measure 17 and 18mm respectively which antibiotic is more effective against sarcina lutea Why?
Antibiotic B is more effective against Sarcina lutea, as it produced a larger zone of inhibition (18mm) compared to antibiotic A (17mm). A larger zone of inhibition indicates that antibiotic B has better inhibitory activity against the bacteria, resulting in better efficacy at controlling bacterial growth.
What other tests does a woman with mastitis undergo?
Tests can be performed to determine what type of antibiotic would be most effective against that particular bacteria.
When are antibiotics not effective?
An antibiotic might not work because the symptoms are attributed to a virus rather than a bacterium. Antibiotics do not work against viruses.
What happens if you give a dog expired amoxicillin?
Hopefully, nothing. Unfortunately, after the drug is expired, the antibiotic and the inert carrier chemicals it is mixed into start to degrade. This degradation is unpredictable in the field and could do anything from rendering the antibiotic inert (ie, no longer an effective drug) to turning the antibiotic or one or more of the other chemicals into a potent toxin that could severely injure or kill the dog.
