A bacteria or virus that causes disease is known as a pathogen.
A pathogen is an agent, such as a virus, bacterium, parasite, or fungus, that causes disease in its host organism. It can infect the host and disrupt normal bodily functions, leading to symptoms of illness.
In science, the term "carrier" typically refers to a substance or organism that can transmit a disease-causing agent without displaying symptoms themselves. Carriers can spread infections to others unknowingly, posing a risk to public health. It is important to identify carriers in order to prevent the further spread of diseases.
Ivanosky (1892) and Beijernick (1898)This view was finally dispelled by Landsteiner andPopper (1909), who showed that poliomyelitis was causedby a 'filterable agent' - the first human disease to berecognized as having a viral cause
A viroid is an infectious agent that consists of a small strand of RNA and that causes disease in plants.
A unicellular infectious agent is a microorganism, such as a virus, bacterium, or protozoan, that is made up of a single cell and is capable of causing infection in a host organism. These agents are responsible for a wide range of diseases in humans, animals, and plants.

A general term for any non-disease causing agent is ________.
Pathogens such as bacteria, viruses, fungi, and parasites are capable of causing disease in humans. These agents can enter the body through various routes and disrupt normal physiological functions, leading to illness and symptoms. Prompt identification and treatment of the specific pathogen are essential to manage and control disease.
