Causes of Blood poisoning

In most cases, blood poisoning occurs when bacteria escape from an infection and enter the bloodstream. Blood poisoning can also result from wounds, burns and infected surgical incisions, all of which release enough bacteria into the bloodstream to cause septicaemia.  Internal conditions ranging from urinary tract infections and pneumonia, to boils, abscessed teeth and gum problems, may cause blood poisoning if enough bacteria escape into the bloodstream. The bacteria from the infected sites are then carried in the blood to the body’s tissues. The immune system attempts to combat this by releasing endotoxins into the bloodstream to defend the blood vessels against leaking. You may feel feverish and chilled, as the body attempts to bring the poisoning under control and prevent fluid loss into tissues. If this not prevented, infections such as meningitis or typhoid that affect the whole body may develop.
