ABSTRACT
Infectious diseases are caused by living organisms that invade and damage organ function – they are commonly termed ‘pathogens’.The means by which pathogens produce disease are almost infinitely variable. The previous chapters have detailed the standard common organ infections such as bacterial pneumonias, viral hepatitis, Helicobacter gastritis and bacterial dysentery. Here, some multisystem infections and parasitic diseases that are encountered both globally and also in Europe are described.
