Bacterial infection, or infection with bacteria, occurs when these microorganisms invade and multiply within the body, causing disease. Bacteria can enter through various routes, such as cuts, respiratory droplets, or contaminated food and water. Once inside, they can produce toxins that damage tissues, evade the immune system, or both, leading to symptoms ranging from mild irritation to severe illness. The body's immune response attempts to fight the infection, but in some cases, this can lead to an overreaction, causing inflammation and further tissue damage. Common bacterial infections include strep throat, pneumonia, urinary tract infections, and sepsis, which can be life-threatening if not treated promptly with antibiotics or other medical interventions. Understanding the mechanisms of bacterial infection is crucial for prevention and effective treatment.
