Antibiotic-resistant bacteria are germs that have evolved to survive despite the presence of antibiotics, which are medications designed to kill or inhibit their growth. This resistance can occur through genetic changes in the bacteria, often due to the overuse or misuse of antibiotics in humans and animals. As a result, infections caused by these bacteria can become difficult to treat, leading to longer hospital stays and increased medical costs. The rise of antibiotic-resistant bacteria poses a significant public health threat worldwide. Common examples include Methicillin-resistant Staphylococcus aureus (MRSA) and Vancomycin-resistant Enterococcus (VRE). Efforts to combat this issue include promoting responsible antibiotic use, improving infection control practices, and investing in research for new treatments.
