A pathogen (Greek pathos (suffering/emotion) and gene (to give birth to)) or infectious agent is a biological agent that causes disease or illness to its host.[1] The term is most often used for agents that disrupt the normal physiology of a multicellular animal or plant. However, pathogens can infect unicellular organisms from all of the biological kingdoms. The term pathogen is derived from the Greek παθογένεια, "that which produces suffering." There are several substrates and pathways where by pathogens can invade a host; the principal pathways have different episodic time frames, but soil contamination has the longest or most persistent potential for harboring a pathogen. The body contains many natural defenses against some of the common pathogens (such as Pneumocystis) in the form of the human immune system and by some "helpful" bacteria present in the human body's normal flora. However, if the immune system or "good" bacteria is damaged in any way (such as by chemotherapy, human immunodeficiency virus (HIV), or antibiotics being taken to kill other pathogens), pathogenic bacteria that were being held at bay can proliferate and cause harm to the host. Such cases are called opportunistic infections. Some pathogens (such as the bacterium Yersinia pestis, which may have caused the Black Plague, the Variola virus, and the malaria protozoa) have been responsible for massive numbers of casualties and have had numerous effects on afflicted groups. Of particular note in modern times is HIV, which is known to have infected several million humans globally, along with Severe Acute Respiratory Syndrome (SARS) and the Influenza virus. Today, while many medical advances have been made to safeguard against infection by pathogens, through the use of vaccination, antibiotics, and fungicide, pathogens continue to threaten human life. Social advances such as food safety, hygiene, and water treatment have reduced the threat from some pathogens.
Pathogens are microorganisms causing illness in other living things. Pathogens can be classified as prions, viruses, bacteria, fungi, protists, or helminthes.
I only know 5 of them:
1) Virus
2)Fungi
3)Bactira
4)Protists
5)Parasites
Bladder Infection and Eye Infection. I just guessed.
disease causing microorganisms are know as pathogens
influenza and... HERPES!!
Bateria and viruse
bacteria that cause human diseases do not grow well at high temperatures
Certain pathogens enter and multiply within the human body.. (:
Organisms that cause plant diseases reduce our ability to produce food and support the economy.Everything from citrus to grains to ornamental plants are susceptible to plant diseases.Plant diseases cause billions of dollars worth of direct and indirect losses every year.Emerging plant pathogens require preparation and planned,scientifically-based response to lessen the impact on our farmers and the economy.
No it does not because I'm smart like that
Your hair carries the same kinds of bacteria (and fungi) as you skin does. These can cause diseases.
Most human pathogens belong to the mesophile group because they are able to survive and grow best at moderate and human temperatures.
vectors cause diseases and transmit around their own sicknesses.
If you have Rickets you can develop holes in your bones like I did when I was a kid.
The optimal temperature for most human pathogens might be expected to range from 25-45°C
Yes, there are examples of pathogens attacking human tissue. An example is Helicobacter pylori forming ulcers in your stomach.
There are four major types of human pathogens: -Bacteria -Viruses -Fungi -and Protists
