It depends, pathogens can be multicellular (cestoda, fungi), unicellular (bacteria) or they can have non-cellular build (viruses, prions).
Euglena are unicellular organisms. They are microscopic, single-celled organisms that are often found in freshwater environments.
The scientific term for unicellular organisms is "unicellular organisms" or "unicellular organisms."
An avirulent pathogen is a pathogen that is unable to cause disease in its host. This may be due to mutations that have reduced its ability to infect or harm the host, making it less pathogenic compared to a virulent pathogen.
There are infinitely many things that do not contribute to the virulence of a pathogen. Elvis does not contribute to the virulence of a pathogen.

pathogen means microorganism, so pathogen diseases means diseases caused by microorganisms

You have to specify the pathogen.
