What are Specific organisms (that may be cellular) with biological chemical or thermal agents that cause disease. i.e. germs and virus are called?

Specific organisms that cause disease, including cellular and acellular entities, are referred to as pathogens. These include bacteria, fungi, parasites (cellular), and viruses (acellular). Pathogens can produce biological, chemical, or thermal agents that disrupt normal biological functions and result in disease in their hosts. Examples include Staphylococcus aureus (bacteria), Candida albicans (fungus), Plasmodium spp. (parasite), and influenza virus.
