Viruses (biological)
A virus is a small infectious agent that can replicate only inside the living cells of organisms. Viruses display a wide diversity of shapes and sizes, called morphologies. Generally viruses are much smaller than bacteria. Most viruses that have been studied have a diameter between 10 and 300 nanometres.

What is a hallmark of the virus group to which CMV belongs?
A hallmark of the virus group is the ability to infect a host and then become dormant. CMV can remain dormant for years. Even in periods without symptoms, the virus can still be periodically shed from the body in fluids like tears.
What are the roles of viruses?
Virus is a program is can damage, spoil the data or files from to be used. It is also can spread easily into computer from e-mail, pendrive download from internet and so on. The antivirus is the tools to prevent it or killer of the virus.
I believe your question is about Polio. Yes, Polio is caused by a virus, named after the disease itself - Poliovirus. Poliovirus is a positive sense single stranded RNA virus of the genus Enterovirus and family Picornaviridae.
When did human immunodeficiency virus?
Acquired Immune Deficiency Syndrome (AIDS) was first recognized as a new disease in 1981.
Viral replication is the process of creating viruses. This can only occur once a virus has infected a cell - because viruses cannot replicate by themselves (they need to use a host cell).
Why are viruses is not grown on cell culture medium?
Viruses are not an organism at all. They are not alive. They are nonliving. They are like cockle burrs that "grab" hold of your clothing or a dog’s coat. They are hijackers. Once they get attached to the cell of a living cell, they can take it over and "make" the living cell produce virus particles instead of cell parts. These particles can assemble into more viruses and then they break out of the cell (killing it) and begin the process again. They cannot make more viruses on their own.
They can only be cultured in living cells.
Attachment, or adsorption, occurs between the virus and the host cell membrane. A hole forms in the cell membrane, then the virus particle or its genetic contents are released into the host cell, where viral reproduction may begin.
What is the outer layer of the virus that helps it enter its host?
The outer layer of a virus is called the capsid. Some viruses have an envelope over the capsid either one help the virus enter its' host.
How dogs get infected by rabies?
like all animals dogs have to be bitten by another animal that already has rabies
What ethnic group does Ebola attack?
The Ebola virus is not not specific to any ethnic group! It is indiscriminate in its selection of human victims!
It is acellular. This means that it has only RNA or DNA and a coat called a capsid.
Will there be a zombie apocalypse in the next few years?
most likely
Becuse it is possible for a Zombie Apocalypse to happen within the next few years but I doubt it because you cannot reanimate dead tissue. However there can be an advanced form of rabies that makes people act like zombies, or there could be a virus created for war purposes but it may get out of control and spread throughout the Earth. so there are many ways for a Zombie Apocalypse to happen.
I for one will survive because of the amount of things around my house I can use for weapons such as swords. WHEN it happens feel free to call 0403938682 for safety and protection. However I can only protect you if you live in New South Wales in Australia.
If you do then it will be your lucky day. See you then.
Is a viral species a group of viruses that have the same genetic information and ecological niche?
no, very similar genetic information. as you and i dont have the same genetic information do we?
same ecological niche? well sorta, i wouldnt call it an ecological niche, the factors that make the niche such as temperature, humidity, host range would be the same.
Will penicillin treat congestion and flu symptoms?
No, not unless the symptoms are caused by a secondary bacterial infection. Antibiotics like penicillin work only on bacteria. The flu is caused by a virus for which antibiotics have no curative effects.
Is rabies shot required if kid got bitten by a Monkey?
no I personally was bitten by a java monkey and I did not have to get a rabies shot, but I did need a tetanus shot.. and that's a pretty big needle!
What are the answers to the explore learning gizmo virus lytic cycle?
You must do the exercises and answer the questions. We can help you with single questions, but doing all the work for you isn't going to help you learn the material.
Why is everybody so worried about the new Chinese Coronavirus, COVID-19, if SARS was more virulent?
Because Trump is trying to handle this outbreak- now pandemic- himself, rather than letting the esperts at the CDC handle it- the premier disease mangement agency in the world. Without the CDC, there is no other system in place because this system works. Without the CDC, we have missed the time to catch COVID-19 early. In contrast CDC handled the SARS in 2002 and EBOLA in 2014, and all the others. They have done an amzing job keepiing us safe. Without the CDC, we have no system. Today we must create a new system for everything involved in addressing this pandemic. Trump continues to look to anyone except the CDC to take charge of this pandemic. That is why the healthcare workers and local politicians are so frustrated with the federal leadership during this occurence. It is interesting that Trump has made no effort to re-establish the CDC Pandemic Team, and is cutting the whole agency further at the same time that we are firghting this pandemic (they are cutting our other safety agencies, too.) We'll be paying for this choice for a long time, and can expect frequent recurrences, unless we regain our respect for our experts who keep us safe everyday.
Yes. Ebola is an extremely serious and deadly virus. Unfortunately more people die from Ebola than recover from it. It depends on where you are located and what kinds of doctors, hospitals, and medications you have access to.
Can you get HIV from scratch marks?
It is very unlikely to transmit/contract the HIV virus in this manner. The "scratcher" could only plausibly do so if there is an open sore(s) under his/her nails, or abrasions caused by violent fighting back and forth. This however is even less likely since the HIV retrovirus is not viable for very long outside of the bodily fluids (esp. blood.) Although it is a bit of a fighting point between caregivers and researchers, it is likely that the virus is rendered noninfectious when it comes in contact with the air.
If you are asking because of a personal incident or a similar event a friend of yours encountered, and the person is known to have HIV, It still would be the best choice to get tested (getting tested periodically is a good idea anyway). But it is very unlikely that HIV was transmitted in this manner. I don't believe there are any documented case where a similar route lead to an infected individual.
Why can bacteria be grown in a petri-dish but not possible for viruses?
Viruses need host cells to replicate and this cannot be done by growing them like bacteria cells are grown.
Dengue fever results in dip in the?
The number of platelets and amount of water. Losing the platelets will prevent normal clotting of the blood.
