What is pathogen disease?
A pathogen is defined as an organism causing disease to its host, with the severity of the disease symptoms referred to as virulence. Pathogens are taxonomically widely diverse and comprise viruses and bacteria as well as unicellular and multicellular eukaryotes.
How do pathogens cause infections?
Pathogens cause illness to their hosts through a variety of ways. The most obvious means is through direct damage of tissues or cells during replication, generally through the production of toxins, which allows the pathogen to reach new tissues or exit the cells inside which it replicated.
What are the 6 pathogens?
They list “The Big 6” pathogens (Norovirus, Nontyphoidal Salmonella, Salmonella Typhi, E. coli, Shigella, and Hepatitis A) as being highly infectious, able to cause severe disease in small quantities, and each will be featured individually in this series of articles.
What are four kinds of pathogens that cause disease in humans?
Different types of pathogens include bacteria, viruses, protists (amoeba, plasmodium, etc.), fungi, parasitic worms (flatworms and roundworms), and prions . While these pathogens cause a variety of illness ranging from minor to life-threatening, it is important to note that not all microbes are pathogenic.
What is the specific disease cause by pathogen?
Some of the diseases that are caused by viral pathogens include smallpox, influenza, mumps, measles, chickenpox, ebola, HIV, rubella, and COVID-19 .
Are pathogens agents that cause a disease?
A pathogen is a biological agent, or germ, that causes disease to its host by interrupting normal body processes. Bacteria, viruses, fungi and parasites are all common types of pathogens that can cause pathogenic, or infectious, diseases.
