It is important to define what do you mention with "microbes". Protists, bacteria and other unicellular organisms are living organisms, with all the "machinery" necessary to leave and multiplicate. They do not need a host.
However, viruses need a host and, thus, they are not considered a living organism.
Basically, all living organisms perform the same basic things, like eat, develop, multiplicate, etc. Unicellular organisms are not an exception.
