Bacterial vs. Viral Pathogens – Amoeba Sisters #Shorts

diseases No Comments »

In this Amoeba Sisters short, the Amoeba Sisters talk about bacterial and viral pathogens. The Short mentions diseases caused by bacteria vs. viruses and some general facts about bacterial and viral pathogens. To see our Amoeba Sisters Shorts Playlist, visit https://www.youtube.com/playlist?list=PLwL0Myd7Dk1Hby0rih8yhnwGUv9lb-2PB To see our longer biology content videos, see our biology learning playlist here https://www.youtube.com/playlist?list=PLwL0Myd7Dk1F0iQPGrjehze3eDpco1eVz #shorts #amoebasisters #amoebasistersshort

The Amoeba Sisters videos demystify science with humor and relevance. The videos center on Pinky’s certification and experience in teaching biology at the high school level. Amoeba Sisters videos only cover concepts that Pinky is certified to teach, and they focus on her specialty: secondary life science.

How are pathogens spread and controlled | Health | Biology | FuseSchool

diseases No Comments »

Pathogens are disease causing microorganisms.

They can be spread in many ways; by direct contact, by water or by air. Different pathogens are spread by different mechanisms.

How can transmission be reduced or prevented?
Depending upon which disease you are trying to reduce transmission for, depends upon which methods you need to engage.

Simple hygiene measures can reduce or prevent the spread of many diseases, including flu and the common cold.

To reduce or prevent cholera and other diarrhoea causing pathogens, communities need access to safe drinking water, adequate sanitation so that dirty water is not exposed and basic hygiene needs such as washing hands properly, boil water properly and keep surfaces clean.

Malaria and yellow fever both have mosquitos as their vector, and lyme disease uses ticks. A vector is an organism that has an active role in transmitting pathogens from one host to another. To prevent or reduce infection from vector borne diseases, the vectors need to be controlled or humans protected against the vector such as wearing mosquito repellent and wearing long sleeved clothing. Insecticide and spraying techniques can be used to reduce the populations of the vectors, but this is trickier and more expensive.

If a disease is highly contagious, such as rabies, people may need to be isolated to prevent the infection spreading to others.

Vaccinations are also an option for preventing and reducing pathogens. Vaccinations involve putting a small amount of inactive or dead pathogen into the body, which stimulates the body to produce antibodies against the specific pathogen. This enables the body to be prepared to attack and destroy this pathogen if they are infected in future.

What Are Pathogens? | Health | Biology | FuseSchool

diseases No Comments »

A pathogen is a microorganism that can cause disease. Pathogens may be viruses, bacteria, protists or fungi.

Examples of bacteria infections are cholera, typhoid, food poisoning and gonorrhoea. Examples of viral infections are the flu (influenza), measles, mumps, the common cold and AIDS. Some common fungal skin conditions are athletes foot and ringworm. Malaria is an example of a protist pathogen.

Now we know about a wide variety of bacteria, as well as precisely how they can harm us. So how do they get spread around? How do communicable diseases get from host to host? Let’s learn all about this process now.
