For example, benzyl penicillin has very little effect on most organisms found in the human digestive system gut. Some bacteria have developed resistance to antibiotics that were once commonly used to treat them. In the past, these infections were usually controlled by penicillin.
The most serious concern with antibiotic resistance is that some bacteria have become resistant to almost all of the easily available antibiotics. These bacteria are able to cause serious disease and this is a major public health problem. Important examples are:. Standard precautions in hospitals are work practices that provide a basic level of infection control for the care of all people, regardless of their diagnosis or presumed infection status. These precautions should be followed in all hospitals and healthcare facilities and include:.
Implementing standard precautions minimises the risk of transmission of infection from person to person, even in high-risk situations. Additional precautions are used when caring for people who are known or suspected to be infected or colonised with highly infectious pathogens micro-organisms that cause disease.
Additional precautions are tailored to the particular pathogen and route of transmission. Additional precautions may include:. Antibiotic resistant bacteria can also be passed from person to person within the community.
This is becoming more common. Ways to prevent transmission of organisms, including antibiotic resistant bacteria, are:. This page has been produced in consultation with and approved by:. Anthrax is a rare but potentially fatal bacterial disease that occasionally infects humans.
The Western obsession with cleanliness may be partly responsible for the increase in allergic asthma and conditions such as rhinitis. In health care, antibiotics are one of our most powerful drugs for fighting life-threatening bacterial infections. Antibiotic resistance happens when the germs no longer respond to the antibiotics designed to kill them. That means the germs are not killed and continue to grow. It does not mean our body is resistant to antibiotics.
Bacteria and fungi are constantly finding new ways to avoid the effects of the antibiotics used to treat the infections they cause.
Infections caused by antibiotic-resistant germs are difficult, and sometimes impossible, to treat. In many cases, antibiotic-resistant infections require extended hospital stays, additional follow-up doctor visits, and costly and toxic alternatives.
Anytime antibiotics are used, they can contribute to antibiotic resistance. This is because increases in antibiotic resistance are driven by a combination of germs exposed to antibiotics, and the spread of those germs and their mechanisms of resistance. When antibiotics are needed, the benefits usually outweigh the risks of antibiotic resistance. However, too many antibiotics are being used unnecessarily and misused, which threatens the usefulness of these important drugs.
For example, too many antibiotics are being prescribed unnecessarily to humans in the United States. If you do not provide this required data, we will not be able to provide you with the services.

No one can completely avoid the risk of resistant infections, but some people are at greater risk than others for example, people with chronic illnesses.
If antibiotics lose their effectiveness, then we lose the ability to treat infections and control public health threats. Many medical advances are dependent on the ability to fight infections using antibiotics, including joint replacements, organ transplants, cancer therapy, and treatment of chronic diseases like diabetes, asthma, and rheumatoid arthritis.
Penicillin, the first commercialized antibiotic, was discovered in by Alexander Fleming. Ever since, there has been discovery and acknowledgement of resistance alongside the discovery of new antibiotics.
In fact, germs will always look for ways to survive and resist new drugs.
