- Pathogen means disease causing microorganisms such as bacteria, fungal and viruses.
- Pathogenic bacteria can causing disease or infections.
- Pathos is the Greek word for "disease" and genes means "born of". So a pathogen is something that causes disease.
- Pathogen spread in several different ways. Forms of person-to-person transmission include air, water,saliva,touch and the exchange of contaminated body fluids.
- An best example of person-to-person transmission is someone with the cold virus coughing or sneezing on someone, allowing the germ to infect another person.
- Although most bacteria are harmless or often beneficial, some are pathogenic.
- Many humans actually host large numbers of bacteria at any given time.
- These bacteria are known as commensal or “good” bacteria
(probiotics), because they perform some vital and useful functions in the human
body. Commensal bacteria in the gut, for example, help to break down and digest
food.
