Infections by bacteria, general or unspecified.
Any disease caused by bacteria. Bacteria exist in a variety of relationships with the human body. Bacteria colonize body surfaces and provide benefits (e.g., by limiting the growth of pathogens and producing vitamins for absorption (symbiotic relationship). Bacteria can coexist with the human body without producing harmful or beneficial effects (commensal relationship). Bacteria may also invade tissues, damage cells, trigger systemic inflammatory responses, and release toxins (pathogenic, infectious relationship).
