Specific bacterial infections are caused by harmful bacteria that invade the body, leading to various health issues. Common examples include strep throat, caused by Streptococcus bacteria, and tuberculosis, caused by Mycobacterium tuberculosis. These infections can affect different parts of the body, such as the throat, lungs, or skin, and may present symptoms like fever, pain, and inflammation. Treatment for bacterial infections typically involves antibiotics, which are medications designed to kill or inhibit the growth of bacteria. However, it's important to use antibiotics responsibly to prevent the development of antibiotic-resistant bacteria, which can make infections harder to treat.
