antibiotic resistance genes

Antibiotic resistance genes are segments of DNA found in bacteria that enable them to survive exposure to antibiotics, which are medications designed to kill them or inhibit their growth. When bacteria possess these genes, antibiotics become ineffective. Resistance can arise from genetic mutations or by acquiring these genes from other bacteria. This phenomenon makes treating infections more challenging and can lead to higher medical costs and increased illness. Understanding and addressing antibiotic resistance is crucial for public health, as it threatens the effectiveness of common treatments for infections.
