Defining Antibiotic-Resistant Bacteria
According to the Centers for Disease Control and Prevention, antibiotic resistance occurs when germs like bacteria and fungi develop the ability to defeat the drugs designed to kill them. That means that germs are not killed and only continue to grow. Resistant infections can be difficult, and sometimes impossible to treat. Examples of antibiotic-resistant bacteria are:
People receiving care in healthcare facilities, like hospitals and nursing homes, can get serious infections called healthcare-associated infections (HAIs). They occur during or after procedures like surgery, or from devices like catheters and ventilators. Sometimes these infections can be caused by antibiotic-resistant germs. Here are some of the ways these infections can spread in a healthcare setting:
Antibiotic resistance affects people at any stage of life. This resistance can lead to extended hospital stays, additional follow-up appointments and the use of treatments that may be costly or potentially toxic. Scientific evidence shows that traces of antibiotics and antifungals, germs resistant to them and genes that cause resistance traits can spread in waterways and soils. Human activity can contaminate the environment (water, soil) with antibiotics and antifungals. Contamination occurs from:
A growing list of infections – such as: pneumonia, tuberculosis, blood poisoning, gonorrhea and foodborne diseases – are becoming harder to treat as antibiotics become less effective. Physicians are unable to recognize antibiotic resistance until the treatment process. For example, an antibiotic that had previously been successful for a patient suddenly stops working or becomes less effective. It takes time to realize what is happening, and meanwhile, the patient becomes sicker. An infection that previously could be treated at home may require a hospital admission.
Over the years, various strains of bacteria have adapted to the medicines that typically kill them. These bacteria fight back against the drugs rendering them ineffective. The bacteria, known as superbugs, continue multiplying and cause infections despite treatment with several antibiotics. Some bacterial infections with superbug status are:
You may be more likely to develop or be impacted by antibiotic resistance if you have AIDS, are being treated for an autoimmune disease (like lupus with immunosuppression therapy), have cancer or are an organ transplant recipient.
