Document Summary
Unlike bacteria and viruses, parasites have a nucleus, larger genomes and more complicated cellular structure: they are eukaryotes. Unlike bacteria or viruses, parasites can be single cells (protozoan) or multicellular (such as helminths) This lecture, we will focus more on helminth infections and next time we will see protozoan infections. Over the last 100-150 years, it has been possible to develop vaccines against bacteria and viruses. Having a larger genome gives them more of an ability to outwit the host systems (they can produce more proteins than bacteria/viruses) 5% of deaths in the developed world are from id. 50% of deaths in the developing world are from id: to a large extent, it is due to parasitic diseases. The number 1 id killer in the world is tb! (#2 is malaria: tb is a bacterial infection. The areas of greatest poverty would mimic what we see in the map above: hiv, malaria and tb are highly prevalent in poorer countries.
