#bacterial infection

Bacterial infections are illnesses caused by pathogenic bacteria multiplying within the body. These microorganisms can invade various tissues and organs, leading to localized or systemic diseases. Common examples include pneumonia, urinary tract infections, and skin infections. Symptoms vary widely depending on the type and location of the infection but often include fever, inflammation, and pain. Treatment typically involves antibiotics, which target and eliminate the bacteria, though resistance is an increasing concern.
