Size range of viruses?
Viruses can vary greatly in size, with the smallest ones being around 20-30 nanometers (nm) in diameter, such as the Parvoviruses. Larger viruses like Mimivirus can reach sizes of around 400 nm. However, most viruses fall within the range of 20-300 nm in size.
Which is the smallest virus?
i think it's Family Parvoviridae (20-25 nm in diameter), that's is according to the book of Maria Danessa Delost entitled Introduction to Diagnostic Microbiology, page 338 isn't it the polio virus??
What viruses have the shape of an icosahedron?
Parvoviruses,papovaviruses,adenoviruses,hepadnaviruses,Herpes virus,picornaviruses,caliciviruses,Reovirus,flavioviruses&Retrovirus.Remember they are either DNA or RNA VIRUSES

What is the smallest group of living things?
The smallest living things depend on how a living thing is defined. Some biologists do not believe viruses are living organisms because there are no free living forms (all are parasitic) and because they must reply on their host for reproduction. Others believe that, despite this, they have an existence of their own separate to the host and are subject to natural selection and are therefore alive. If you accept viruses are not alive, the smallest living things would be amongst the bacteria or protists. Bacteria are single celled organisms with no cell nucleus while protists have a nucleus. Generally the bacteria are slightly smaller but their sizes overlap. If you accept that viruses are alive, the smallest group are the Parvoviruses between 18 and 26 nanometres. These are single stranded DNA viruses. 1 nm = 1/1000000000 metres or 0.000039 inches.

What is a smallest organism?
The smallest organism in the world is a virus, although many biologists consider viruses to be non-living because they lack a cellular structure and cannot metabolize by themselves, requiring a host cell to replicate and synthesise new products. A minority of scientists hold that because viruses do have genetic material and can employ the metabolism of their host, they can be considered organisms. The smallest RNA viruses in terms of genome size are small retroviruses such as rous sarcoma virus with genomes of 3.5 kb and particle diameters of 80 nm. The smallest DNA viruses are the hepadnaviruses such as Hepatitis B, at 3.2 kb and 42 nm; parvoviruses have smaller capsids, at 18-26 nm, but larger genomes, at 5 kb. The smallest DNA bacteriophage is the Phi-X174 phage, thought to be larger than Hepatitis B, at about 4 kb. It is important to consider other self replicating genetic elements such as satelliviruses, Viroids and Ribozymes. The Porcine circovirus 2 is a single stranded DNA virus having a capsid diameter of 17 nm. In which that case, the smallest living organism in the world would be a nanobe. Nanobes are thought by some to be the smallest known organism, about one tenth the size of the smallest known bacteria.

Can the parvo dog virus be transmitted to humans?
Rest assured that parvovirus is specific to dogs alone and cannot be transmitted to humans or other pets of a different species, such as cats.got this info from http://www.workingdogs.com/parvofaq.htm*But, however, humans can get a different form of this virus that is often called Fifth Disease. The real name is Parvovirus B19. Another name for it is Erythema Infectiosum which is also called Slapped Cheek Syndrome.
What is the viral disease of cattle called?
Companion animals such as cats, dogs, and horses, if not vaccinated, can catch serious viral infections. Canine parvovirus 2 is caused by a small DNA virus, and infections are often fatal in pups.The emergence of the parvovirus in the 1970s was the most significant in the history of infectious diseases. The disease spread rapidly across the world, and thousands of dogs died from the infection.The virus originated in cats, the vector of feline panleukopenia, but a mutation that changed just two amino acids in the viral capsid protein VP2 allowed it to cross the species barrier, and dogs, unlike cats, had no resistance to the disease. Canine distemper virus is closely related to measles virus and is the most important viral disease of dogs. In the 1990s, thousands of African lions died from the infection, which they contracted from feral dogs and hyenas.Marine mammals are susceptible to viral infections. In 1988 and 2002, thousands of harbor seals were killed in Europe by the measles-like phocine distemper virus. Large outbreaks of the disease were recorded among the seal populations of Lake Baikal and along the shores of the Baltic and North Sea. The infection resembled canine distemper; the animals died within two weeks of respiratory distress and many aborted pups were seen.Many other viruses, including caliciviruses, herpesviruses, adenoviruses and parvoviruses, circulate in marine mammal populations.
What is paarvo?
Paarvo is a disease. It is common in dogs. It can be deadly. There is a vaccination which will help protect your dog. See your Vet for the vaccination. Usually dogs are vaccinated at an early age as puppies to help protect them from this diseasse. The vaccination, if not given properly can also cause the disease.RE:Paarvo (which is, by the way, spelled 'parvo' and is also known as parvovirus) is a deadly and contagious disease common in canines of all ages. The following was from the site: http://www.peteducation.com/article.cfm?c=2+1556&aid=467. I do not claim this information.) There is a broad range in the severity of symptoms shown by dogs that are infected with parvovirus. Many adult dogs exposed to the virus show very few, if any, symptoms. The majority of cases of disease are seen in dogs less than 6 months of age with the most severe cases seen in puppies younger than 12 weeks of age. There are also significant differences in response to parvovirus infections and vaccines among different breeds of dogs, with Rottweilers, Doberman Pinschers, and Labrador Retrievers being more susceptible than other breeds. The most common form of the disease is the intestinal form known as enteritis. Parvovirus enteritis is characterized by vomiting (often severe), diarrhea, dehydration, dark or bloody feces, and in severe cases, fever and lowered white blood cell counts. Acute parvovirus enteritis can be seen in dogs of any breed, sex, or age. The disease will progress very rapidly and death can occur as early as two days after the onset of the disease. The presence of gram negative bacteria, parasites, or other viruses can worsen the severity of the disease and slow recovery. The treatment of parvovirus is fairly straightforward and directed at supportive therapy. Replacing fluids lost through vomiting and diarrhea is probably the single most important treatment. Intravenous administration of a balanced electrolyte solution is preferred, but in less severe cases, subcutaneous or oral fluids may be used. In severe cases, blood transfusions may be necessary. Antibiotic therapy is usually given to help control secondary bacterial infections. In those dogs who have severe symptoms, antiserum against endotoxins may be given. Corticosteroids may be given if the animal is in shock. In cases of severe vomiting, drugs to slow the vomiting may also be used. After the intestinal symptoms begin to subside, a broad spectrum de-worming agent is often used. Restricting the food during periods of vomiting is also necessary and parenternal nutrition (providing nutrients intravenously) may be necessary.Undertaking the treatment of affected dogs and puppies without professional veterinary care is very difficult. Even with the best available care, the mortality of severely infected animals is high. Without the correct amount of properly balanced intravenous fluids, the chance of recovery in a severely stricken animal is very small.All parvoviruses are extremely stable and are resistant to adverse environmental influences such as low pH and high heat. Exposure to ultraviolet light and sodium hypochlorite (a 1:32 dilution of household bleach - ½ cup bleach to 1 gallon of water) can inactivate parvovirus. The bleach solution can be impaired by organic matter and needs to have adequate exposure time and proper concentrations to work effectively.As I said, I do not claim this information.
