Superbugs are bacteria that are resistant to multiple antibiotics, posing a serious threat to patients, especially those with compromised immune systems. They are a driving force behind the need to develop new classes of antibiotics. Hospitals are an ideal breeding ground for multi-resistant bacteria. The emergence of a superbug that has resisted all drugs could be a public health disaster.
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 worldwide, 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 the bacteria, but some bacteria usually continue to grow. In relatively healthy individuals, the immune system can kill 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 very uncommon in the bacterial community, thanks to the exchange of genetic material between bacteria. When a bacterium becomes multidrug-resistant, however, it can become a serious problem, as it can pass on multidrug-resistant genes and create a superbug. Treating superbugs is challenging, as you either need to culture the bacteria to find out which antibiotic can be used against them, or use multiple rounds of antibiotics in an attempt to kill them and hope that using multiple antibiotics doesn’t actually create more. resistance to antibiotics.
Some notorious superbugs include bacteria of the genera Streptococcus and Enterococcus, along with Staphylococcus aureus and Clostridium difficile. These superbugs are commonly seen in hospital settings, because hospitals are an ideal breeding ground for multi-resistant bacteria, among all the antibiotics used in a hospital setting, and all sick patients vulnerable to bacterial colonization. Concerns about drug resistance have led many hospitals to implement strict sterilization and sanitation policies to reduce the risk of transmission of drug resistant organisms among patients.
A superbug’s biggest concern is the development of a bacterium that would be able to resist all antibiotics on the market, effectively making its eradication impossible. As it stands, treating patients with superbug infections is complicated by the cost of antibiotics, each patient’s individual health concerns, the affordability of medications, and the difficulty of getting patients to adhere to antibiotic regimens. The emergence of a superbug that has resisted all drugs could be a public health disaster.
