What are substances made from dead viruses?
Vaccines for the prevention of the specific viral infection can be made with inactive "dead" viruses. They are also made with live, but attenuated (weakened), viruses. See more below about vaccines.
How long do Bacteria and viruses survive on a dry surface?
Most viruses can remain airborne a very short time. Usually sunlight or dry air will inactive them.
Why viral specimens must be stored under -70 centigrade?
Because at this temperature almost all viruses are inactive and not harmful .
What dd Jonas salk invent?
Dr. Jonas Salk invented the first poliomyelitis vaccine containing inactive viruses.
Why do you develop a fever after a measles vaccination?
Any vaccine injects inactive viruses. This does not mean you will get the virus, but you might experience some symptoms similar.
What is lacking in a Virus which makes it dependent on a living cell to multiply?
Viruses lack the supply of chemical constituents needed to assemble more viruses; these chemicals can be found inside cells (which use them for their own cellular reproduction when they have not been hijacked by an invading virus).
Immunizations have small doses of what in them?
Parts of individual bacteria or viruses that have been killed and broken up into inactive bits. The immune system can recognize them and develop immunity.
Do viruses die if they have no host to infect?
Viruses are not considered alive as they lack the ability to perform metabolic processes on their own. Outside of a host cell, viruses can become inactive but not die in the same way living organisms do. They can remain intact for extended periods until they come into contact with a suitable host.
The tiniest and toughest pathogens are?
The tiniest and toughest pathogens are viruses, particularly those that have a lipid envelope protecting their genetic material. These pathogens are able to survive in various environments and can be difficult to eradicate due to their small size and ability to rapidly mutate.
What type of phage enters an inactive prophage stage?
A temperate phage is a type of phage that can enter an inactive prophage stage by integrating its DNA into the host cell's genome. In this stage, the prophage replicates along with the host cell's DNA and can be passed on to daughter cells during cell division.
