No bacteria is huge compared to a virus
You can get it from wild animals such as stray dogs. Or they did not get their shots.
If I remember correctly, the work by Michael Crichton details aboutthe strains of Ebola that got loose in the US.
Viruses first need to enter a host, then infect a living cellwithin the host. The virus does this by using proteins thatessentially act like a key to enter a host cell. Once the virus isinside it alters the DNA of the cell so that the host cellessentially begins to make copies of the virus. The...
They can and do cause diseases.
MVC is usually diagnosed after death. Pups fall victim either inthe womb or at a very early age. Treatment is not usually possible- pups die so suddenly that there is no time to implement atreatment plan.
Technically, no.. that is why viruses are hard to treat. When you have a bacterial infection, you go to the doctors and he gives you antibiotics which kills the bacteria and makes you better. However if you have a viral infection, ever notice how you dont get any prescription? That's because of the...
They are not alive. They wait until they can attach to a cell.
Viruses are composed of two main parts: an outer protein coveringcalled a capsid and an inside core of either DNA or RNA.
Defensive or drug resistant viruses grow by mutation. Viruses areexposed to many cellular factors during the replication of viruses,some of the factors can do actually mutate the viral genomes.Viruses take advantage of these factors to form as a geneticallymodified (new) virus that may not be cured...
Fog is a meteorological phenomenon, not a virus.
With fluids and other support plus some can be treated withantivirals.
Trichomoniasis and public lice are STDs that are neither bacterialnor viral.
Each type of virus will respond differently depending on theenvironmental conditions. In the following, the words "live" or"die" are used; although, these terms are slightly inaccurate sincea virus is not a living organism. Viruses do have the need for ahost, to keep them able to infect other hosts...
Decapitation is worse than a virus.
DNA is not a virus or a bacteria
Rabies is a viral disease caused by a virus infected dog biting. It is most prevalent in countries of Asia and Africa. It is estimated that rabies causing 55,000 human deaths annually.
Ebola virus is one of five known viruses within the genusEbolavirus. Four of the five known ebolaviruses, including EBOV,cause a severe and often fatal hemorrhagic fever in humans andother mammals, known as Ebola virus disease.
virus are connecting link between living and non-living. As they possess the capabilty of multiplying themselves which is the general propertiy of living beings but they can not multiply all alone or we can say that they need a living cell as a host in which they can take over the DNA replication...
No. The vaccine is only a part of the virus that your body willrespond to.
It has matching proteins on it's capsid that match ones on certainhost cells.
Rabies causes inflammation of the brain in human
Self replication, metabolism, nutrient uptake and excretion, areall absent in viruses
Yes they can stay dorman for a while and active again. In some bacteriaphages there is a replicaiton cycle exist called lysogenic cycle where the phage DNA kept dormant in host. but this can change when a stimuli triggers them, it enters to lytic cycle and kill the host.
Viral infection can be prevented, but not cured, by vaccines.
Good question! It is still unclear how HIV packages exactly twocopies of their RNA genome in the particle. But what know is theseRNA interact to form dimers, and these dimers may be well enough tobe accommodated in the the capsids or gag molecules prior tobudding.
The word rabies has its origin from the Sanskrit word "rabha" meaning Rage.
Viruses are not composed of cells.
It only takes up to a couple of weeks to die from the Ebola virus.It takes about the same amount of time to recover from the virus.About 40% of people survive after being infected.
Influenza, commonly known as the flu, is a disease of the respiratory system. It affects the lungs, throat, and sinuses.
Rabies virus affect nervous system. It is transmitted through the saliva of an animal before they die. It can affect the muscular system as well and cause paralysis.
Bacteria are normally larger than viruses but smaller than eukaryotic cells. the bacterial cell size ranges between 0.5 to 5 micrometers in length (10 times smaller than eukaryotes). Viruses are ultra microscopic, their size ranges between 20-500 nanometers, it can be detected by electron...
only one person per century.
It is called infection. Virus mostly infects via cellular receptor interaction (CD4 and CXCR4 in case of HIV). After infection the viuus enters the cell and establish its replication cycle on host.
In T4 phage vius replicate via lytic cycle. Phage DNA can be integrated in to the bacterial DNA for the production of viral structural and functional protein and viral genome. it packages to progeny viruses and release by rupturing the cell.
? chicken pox is a disease caused by viruses called the varicella zoster virus (which also causes shingles). viruses are not normally considered organisms because they don't meet all the characteristics of living things.
Viruses are ranges in different sizes and structures. HIV, HBV, influenza are all spherical in shape. Phages like T phages carry an icosahedral structures. M13 phages, ebola appear as hair like (or tube) structures. TMV appears as rod like structure.
Retroviruses such as HIV, HTLV, SIV, MLV. Plant virus Cauliflower mosaic Virus, TMV. Phages such as T4, T7, lambda, M13. Other viral pathogens Ebola, HBV, HCV, Foamy virus, Mumps, measles,pox, rabies and so on. Viruses are classified on the basis of their genetic material (DNA,RNA)
All viruses are sharing a common feature that their genetic material DNA or RNA in packed in a protein coat capsid. Enveloped viruses may contain glycoproteins on their envelope (eg:HIV). Virus can not replicate or reproduce themselves, they need to infect their host and integrate their genome into...
The Avian "Bird" flu is passed to humans by birds and their saliva and feces. Other forms of influenza that humans can get are also mutations of viruses that birds have had, some are from pigs (like swine flu) and many are from a combination of various swine, human, other, and bird flu strains that ...
A bacteria or virus that causes disease is known as a pathogen.
India has the most cases of rabies per year.
Yes, by inserting its DNA or RNA into that cell.
Virus penetrates its genetic material into the host. The genome is then inserted randomly on a point of the host genome. Since it is an random event, it can block a pathway of that particular or cause any mutation due to the insertion of viral genome.
It is difficult because viruses lack the ability to replicate themselves and theey lacks energy metabolism and other pathways that living things have. Viruses are totally depending on their host. If they want to replicate, they have to infect the host.
Hershey and Chase knew that the particular phage they worked with has two basic components: DNA on the inside, coated with protein on the outside. In their expt theylabelled phages with radioisotopes . For one batch of infecting phages, they used a radioactive isotope of sulfur to label only the...
You really should rest when you have an infection like the flu. Since the symptoms usually last only a week for most people, try to avoid the exercise if you can. If you must exercise, it should be light exercise only. Working with weights and other heavy exercise or running should be avoided. ...
They can be used in genetic modification as a vector to insert geneinto the genome of a target cell. This has happened naturally in a few occasions, hence why much ofhuman DNA is derived from viruses (retroviral DNA).
Rabies is a viral disease.
They are smaller than bacteria or other micro organism. It ranges 20-500 nanometers, ultra microscopic size. Viruses can be detected only by electron microscopes or other high resolution optics.
Viruses are too small for van Leeuwenhoek to have seen with his simple microscope.
Virus live inside "host cells"of living creatures. There is an attraction of certain types of virus to certain cells. This is why cold virus "likes" lung tissue and sinus. Or herpes likes human lips and sexual skin tissue. It is attracted based on the nature of the virus and the types of proteins...
Virus can not be termed as a living thing or organism. Viruses can not replicate themselves, they are dependent on its host. The only similarity is it contain genetic material such as DNA or RNA like living things which codes for its proteins.
The cell on which a virus lives is the host cell.
Yes, it can be a common symptom of the flu. Fluid in the inner ear, drugs, sugar and excessive amounts of caffeine have also been known triggers. Maintain hydration.
It depends. Ebola virus Is a highly infectious disease. It is spread not only by the living, but also by the dead. Funeral ceremonies can be a source of exposure of the virus to a large gathering of people. In countries where cadavers of people who died of Ebola are not handled aseptically, the...
you can contract rabies from blood, tears, and saliva of any infected animal.
If you are over 18. The NSAID (non-steroidal anti-inflammatory drug) Aspirin (ASA, acetylsalicylic acid) can be used as an antipyretic - which means, it will help to reduce fever. Fever reducers are good to use if the fever is high, e.g., 102 F (38.89 C) or over . It is better for many people to...
viruses are those living organisms which live inside the host cell and reproduce but its free means outside the cell they cannot respire ,reproduce etc thats why we considered virus as non-living.
Virus lack metabolic pathways or any other life activity. This is the reason virus is known as particles and not as life form. they require their host for the replication and dependent of host machinery.
on the east coast by racoon's. very little from dogs. and very slim chance of getting one from a bat. same on the west coast. mostly raccoon
Viruses can cause detrimental effect on their host. They can cause a disease like Polio, pox, rabies etc. or they can impairs the immunity of our body such as HIV. They can also able to cause cancers in case of HTLV.
The vaccine was first developed by Pasteur and Roux in the late 19th century. There is no known cure as such for rabies, but there have been developed some methods of which may pose as a working approach. Treatment for rabies consists of, basically, attempting to prevent rabies from developing...
As medical discoveries go, influenza viruses were late to be isolated, mostly because of their sub-microscopic size. In 1901 the hint of the existence of these infectious agents was found when it was proved that the "germ" was not bacteria by discovering that it passed right through a filter that...
because the viruses do not have the ability to replicate themselfs.
The lysogynistic cycle where they insert their DNA/RNA into the hosts genetic material for many rounds of their own replication along with the hosts replication.
A prion is the smallest known thing that can cause disease.
From the host cell. They do not have a metabolism outside of the cell
As far as we know, Ebola attacks mostly primates. There is some indication that it may also attack the Afrtican Fruit Bat (and by inference, other mammals as well). Some variants of Ebola, notably Ebola reston, were lethal to monkeys but apparently infected humans although -- in humans -- it...
A fever is a direct response of the immune system. The body will attempt to destroy the infectious agents by raising the core body temperature. This increase helps create an environment unsuitable to bacterial growth as well as disrupts metabolism and function of the infecting agent.
A virus doesn't destroy the host cell's DNA. The virus depends onthe cell's DNA to keep the cell functioning while the virusreproduces. The viruses that actually kill the cell only destroythe DNA indirectly. Once the structure of the cell is broken up inthe process of death the DNA is exposed to the...
are you kidding me , yes it is a BREATHTAKING VIRAL DISEASE Medical officer of Health (H.O.H) Kangra
All viruses are obligate pathogens.
Yes.It infects fungi,plants,animals and bacterias
It is unknown if a hamster at pet-land had or has rabies. Rabies is a virus that can effect any mammal. the likely hood that a hamster would have rabies is not high simply because they would have to come in contact with another mammals saliva... normally through a bite wound. it is safe to say that...
Viruses can't survive too long outside the host and need it alive in order for them to survive. Living beings provide the ideal environment for viruses to thrive, such as temperature etc.
Rabies affects the nervous system.
* A +* is not made of cells.
I don't no can u help me with it
Its the same thing with humans. Rabies manipulate the brain and u become rabid and out of control. Almost every single case of rabies has killed a human. To my knowledge no human has lived after being infected.
If you have not been vaccinated for the specific subtype of influenza that is spreading in your environment, then you are susceptible to the infection unless you have already had the same virus or a very similar one. If you do not have immunity through one of these methods, then you may catch the...
Use of antiviral creams, such as acyclovir, valtrex, and famvir can be used to fight the outbreak.
