Antibiotic Resistance

Antibiotics are one of the most important discoveries of modern medicine, saving millions of lives by treating infections caused by bacteria.

Although antibiotics kill most bacteria, some will survive. The bacteria that survive have developed resistance. Antibiotic resistance occurs when the bacteria cannot be killed by an antibiotic.

About

Using antibiotics when they are not needed can lead to antibiotic resistance. Antibiotics will not kill resistant bacteria and, even worse, resistance can be transferred from one bacterium to another. Antibiotics are specific and are only effective against bacterial infections. 

A public health concern

It is important to remember that it is the bacteria that are resistant, not the individual. Even very healthy people who have never taken an antibiotic can become infected with antibiotic-resistant bacteria. That is why antibiotic resistance is a public health issue:  the public needs to use antibiotics wisely so that individuals are not adversely affected.   

Respiratory tract infections

With the exception of pneumonia, most respiratory tract infections resolve on their own, without antibiotics.  Infections that are due to viruses include colds, influenza (the "flu"), croup, laryngitis, bronchitis, bronchiolitis, most sore throats as well as some ear and sinus infections and do not require antibiotics. 

Viruses

Viruses do not need antibiotics. Although ear and sinus infections can be caused by either bacteria or viruses, bacterial infections often develop after a viral infection and usually resolve without antibiotics. The Canadian Pediatric Society recommends watchful waiting as the preferred treatment for ear infections in children over the age of  6 months to see if the infection will go away on its own. 

In the news

CBC-TV's The Nature of Things presents Antibiotic Hunters. This documentary travels to an ocean reef, a rainforest canopy, a frigid cave and even the mouth of a giant lizard - all in the urgent search for new antibiotics. Watch the episode here.

Upcoming events

November 13 - 19, 2017 is World Antibiotic Awareness Week
