What is a Superbug?

A superbug is a bacterium that has developed resistance to multiple antibiotics. Also known as multidrug-resistant bacteria, superbugs are a major concern in the public health community around the world, as they pose a serious threat to patients, especially hospitalized patients and patients with compromised immune systems. These bacteria are also of interest to pharmaceutical companies, as they are a driving force behind the need to develop new classes of antibiotics.

Superbugs develop because bacteria are highly adaptable. When antibiotics are introduced into the body in an attempt to eradicate bacteria, these drugs are often very effective at killing bacteria, but some bacteria usually continue to grow. In people who are relatively healthy, the immune system can eliminate these bacteria, but in others, the bacteria will multiply and spread, passing on the gene for resistance to a specific antibiotic.

Resistance to an antibiotic is not uncommon in the bacterial community, thanks to the exchange of genetic material between bacteria. However, when a bacterium becomes multi-resistant it can become a serious problem as it can pass on the multi-resistant genes and create a superbug. Treating superbugs is challenging, as you need to either culture the bacteria to find out which antibiotic can be used against them, or use multiple courses of antibiotics in an attempt to kill them, and hope that using multiple antibiotics won't actually creates more resistance to antibiotics.

Some infamous superbugs include bacteria in the genera Streptococcus and Enterococcus, along with Staphylococcus aureus Y Clostridium difficile . These superbugs are commonly seen in hospital settings, because hospitals are an ideal breeding ground for multidrug-resistant bacteria, among all the antibiotics used in the hospital setting, and all sick patients who are vulnerable to bacterial colonization. Concerns about drug resistance have led many hospitals to implement strict sterilization and hygiene policies to reduce the risk of transmitting drug-resistant organisms between patients.

The biggest concern with a superbug is the development of a bacteria that is capable of resisting all antibiotics on the market, making it effectively impossible to eradicate. As it is, treating patients with superbug infections is complicated by the cost of antibiotics, individual patient health concerns, accessibility of medications, and difficulty in getting patients to adhere to regimens. of antibiotics. The emergence of a superbug that resists all drugs could be a public health disaster.
