Multidrug resistant bacteria are bacteria that have developed resistance to multiple antibiotics, making them difficult to treat. They pose a significant challenge in clinical settings and public health due to limited treatment options.
5 Must Know Facts For Your Next Test
Multidrug resistant bacteria can arise through gene mutations or by acquiring resistance genes from other bacteria.
Common examples include MRSA (Methicillin-resistant Staphylococcus aureus) and VRE (Vancomycin-resistant Enterococci).
The misuse and overuse of antibiotics in humans and animals accelerate the development of multidrug resistant bacteria.
These bacteria can cause severe infections that are harder and more expensive to treat, often requiring alternative medications with more side effects.
In hospitals, strict infection control measures are necessary to prevent the spread of multidrug resistant bacteria.
