Cellular and Non-Cellular Pathogens is a part of the VCE Biology area of study ‘How do Cells Communicate?’ and subtopic ‘Responding to Antigens’. A pathogen is a disease-causing agent which disrupts the functioning of infected organisms. Pathogens can be cellular, such as parasites, protozoa or bacteria, or non-cellular, such as viruses and prions.
