What Is Antibiotic Resistance_
                     What Is Antibiotic 
Resistance?
The term antibiotic resistance (AR or 
ABR) is a subset of AMR, as it applies 
only to bacteria becoming resistant to 
antibiotics. Resistant bacteria are more 
difficult to treat, requiring alternative 
medications or higher doses, both of 
which may be more expensive or more 
toxic.
Sometimes, the antibiotic can be used in non-
standard ways to effectively treat infections caused 
by resistant bacteria. Medications that kill or 
prevent the growth of bacteria are called 
antibiotics. 
Know More- What is Antibiotic Resistance?
The use of antibiotics and the 
development of resistance has had an 
intertwined history. 
Bacteria and other microorganisms 
that cause disease have evolved 
mechanisms to defend themselves 
from the actions of antibiotics.
Antibiotics are a class of medicines that 
are used to treat infections caused by 
microorganisms (bacteria). Antibiotic 
resistance occurs when pathogens, such 
as bacteria, become resistant to the 
action of antibiotics.
Infections from antibiotic-resistant 
bacteria are difficult, and sometimes 
impossible, to treat. For some 
infections, with few or no treatment 
options available, patients may die as a 
result of an antibiotic-resistant 
infection.
Antibiotics can save lives—but any 
time antibiotics are used, they can 
cause side effects and lead to 
antibiotic resistance.
Antibiotic resistance happens when 
germs like bacteria and fungi develop 
the ability to defeat the drugs 
designed to kill them. That means the 
germs are not killed, and continue to 
live and possibly spread.
Taking antibiotics when they are 
not needed means that you are 
more likely to be exposed to 
resistant bacteria.
