This is a condition in which there is a bacterial infection focus somewhere in an organ or tissue, and bacteria are constantly or intermittently leaking from that focus into the bloodstream. If the body's defenses are weak, the bacteria are highly virulent, or both coexist, new lesions will form in a location separate from the original focus, progressing to sepsis. Blood cultures are performed to confirm bacteremia, but it is often difficult to strictly distinguish between bacteremia and sepsis.

臓器あるいは組織のどこかに細菌感染巣があって,絶えずあるいは断続的に,その病巣から細菌が血液中に流出している状態をいう。生体の防御力が弱いか,細菌の毒力が強いか,あるいはその両者が併存する場合には,原病巣と別の部位に新しい病巣をつくって敗血症に進展する。菌血症を証明するには血液培養を行うが,菌血症と敗血症の厳密な区別は困難な場合が少くない。
