What are Antibiotic Resistant Bacteria?

Antibiotic resistant bacteria are bacteria that cannot be fully inhibited or killed by an antibiotic. The antibiotic may have worked effectively against that bacteria before the resistance occurred. Bacteria become resistant to antibiotics by adapting their structure or function in some way that prevents them from being killed by the antibiotic. This mechanism might happen in several ways:

  • bacteria can neutralize the antibiotic before it has an effect


  • bacteria may be able to pump the antibiotic out


  • bacteria may be able to change the site (receptor) where the antibiotic normally works


  • bacteria can mutate and transfer genetic material that codes for resistance to other bacteria


The resistant bacteria that survive the effect of the antibiotic are able to multiply, spread to others and cause further infections in the family, community, and/or health care setting. In turn, patients infected by these resistant bacteria take the same antibiotic and see little or no effect!

These bacterial infections are more resistant to another round of the same antibiotic.


What happens when there are no antibiotics to treat infections anymore? Scary right!

You can help by avoiding indiscriminate use of antibiotics which includes self medication and use of expired antibiotics. You should also complete the prescribed dosage regimen, even when you feel better.

As such, they are developing resistance to these antibiotics. […]
