Pathogen
An organism that causes disease
A pathogen is an organism, such as a virus, bacteria, fungi or parasite, that causes diseases in other living organisms. They can infect humans, animals, plants, or even bacteria themselves. Pathogens have the ability to invade and replicate within the host organism, leading to a range of symptoms and potential health complications.
Pathogens can be transmitted through various routes such as air, water, food, bodily fluids, and even via contact with animals or objects contaminated with the pathogen. Once inside the host, the pathogens may multiply and produce toxins that damage or kill host cells, leading to illness.
Some examples of pathogens include the influenza virus, Salmonella bacteria, HIV virus, and Plasmodium parasite that causes malaria. Effective management of pathogens may involve vaccination, antibiotic treatment, good personal hygiene, and proper sanitation measures to prevent the spread of diseases.
