Microparasite
Encyclopedia
A microparasite is a parasite that complete a full life cycle
within one host
and can be transmitted directly to conspecific
hosts. They often reproduce within a host's cells and are generally too small to be seen with the naked eye. Most are viruses, bacteria
and fungi with a smaller number being protists. Examples include salmonella
and HIV
