Our gut is permanently full of large numbers of bacteria and other organisms but serious infections relatively rarely occur due to its extraordinary immune system. Infections of these organs can, however, occur in specific situations. Specialised bacteria and parasites can damage the gut or its functions including direct invasion or toxins. The liver can be damaged by hepatitis viruses, parasites and other infections.
Common gut bacteria (Gram negative bacteria) which in their normal place inside the gut cause no serious problems occasionally bypass the body's defences and can set up serious infections including septicaemia. Public health including the sanitation movement reduced but has not eliminated transmission of these potentially dangerous infections. This lecture will consider infections that normally live inside our gut, how the body keeps them there and what happens when this fails.
