What is porvovirus in humans?
920738
I think you mean parvovirus?\n\nParvovirus, commonly called parvo, is a genus of the Parvoviridae family linear, non-segmented single stranded DNA viruses with an average genome size of 5 kbp. Parvoviruses are some of the smallest viruses found in nature (hence the name, from Latin parvus meaning small).\n\nTake a look here:\nhttp://en.wikipedia.org/wiki/Parvovirus\n\nMany types of mammalian species have a strain of parvovirus associated with them. A parvovirus tends to be specific about the taxon of animal it will infect. That is, a canine parvovirus will affect dogs, wolves, and foxes, but will not infect cats.\n\nHumans have their own strain of parvovirus which can spread rapidly from person to person.

The virus mutated when it reached humans, so it is in a different form.

Ummm...a germ or virus. Airborne, surface borne (two day life span)

humans can not catch parvo..its only a animal disease

i think human diseases r interesting. besides that, how bout healing properties of some tradisional herbs/plants? i'm currently working on pathogenic bacteria. maybe u can try to look into pathogens too? since pathogen like SARS, avian influenza and HIV are emerging problems for mankind... most importantly, which area r u interested?

This review addresses both historical and recent investigations into viral contamination of marine waters. With the relatively recent emergence of molecular biology-based assays, a number of investigations have shown that pathogenic viruses are prevalent in marine waters being impacted by sewage. Research has shown that this group of fecal-oral viral pathogens (enteroviruses, hepatitis A viruses, Norwalk viruses, reoviruses, adenoviruses, rotaviruses, etc.) can cause a broad range of asymptomatic to severe gastrointestinal, respiratory, and eye, nose, ear, and skin infections in people exposed through recreational use of the water. The viruses and the nucleic acid signature survive for an extended period in the marine environment. One of the primary concerns of public health officials is the relationship between the presence of pathogens and the recreational risk to human health in polluted marine environments. While a number of studies have attempted to address this issue, the relationship is still poorly understood. A contributing factor to our lack of progress in the field has been the lack of sensitive methods to detect the broad range of both bacterial and viral pathogens. The application of new and advanced molecular methods will continue to contribute to our current state of knowledge in this emerging and important field.

Some viruses are not specific to animals or to humans and can be passed back and forth.  For example, the avian flu.  \nAlso, horses are susceptible to many human ailments.  These viruses are transferred just like any virus, through ingestion of some sort.  This means you breath it in if it is a virus that can survive while airborne, or you can eat it, drink it or get it into your body through sores or sensitive areas like your eyes or "other areas"(HIV).  Say an animal is sick and you kill it and eat it.  Maybe the virus withstands great heat and cooking the meat of the infected animal doesn't kill it.  Eating the meat will pass the virus.  You could touch the sick animal, get contaminated saliva on your hands and then you touch your mouth or eyes; you will get sick. \n\nMost viruses are specific to certain species though.  An animal virus only affects animals and a human virus only affects humans.  Still these viruses can mutate into a virus that affects humans and animals.  That is what is so scary about viruses.  They multiply quickly and mutations are very common.

Viruses are infectious agents that require cells for their reproduction.  The replicate by controlling a living cell’s material independently of the cell’s DNA.  This cell is called a Host.  The viral genetic material can be double stranded DNA, single stranded DNA or RNA.  A virus out side of a living cell is called a virion and is metabolically inert.  (It is also covered by a protein or other coating).  They do mutate readily.\nOnce inside a living cell, the virus sheds it’s coating and deactivates much of the genetic material of the cell, only allowing that which it needs or which do not interfere with their replication.  They then force the cell to replicate their genetic material as new virions which will be released when the cell ruptures.\nOpite gave good info on the size of the virus in terms of linear measurements.  Size, in terns of the number of bases runs from as few as 5,000 bases (single strand DNA) for the H-1 parvovirus to about a half a million base pairs in the largest.\nViruses are not considered to be alive.

I don't know off the top of my head, but try looking here. It has loads of good and useful virology info.\nhttp://www-micro.msb.le.ac.uk/

Not really... The hanta virus is transmitted by rodents. Check the official page of the Centre for Disease Control (government site)

Parvoviruses can cause disease in some animals. Because the viruses require actively reproducing cells in order to replicate, the type of tissue infected varies by the age of the animal. The gastrointestinal tract and lymphatic system can be affected at any age, leading to vomiting, diarrhea and immunosuppression, but cerebellar hypoplasia is only seen in cats that were infected in the womb or at less than two weeks of age, and disease of the myocardium is seen in puppies infected between the ages of three and eight weeks. [1]\n\nCanine parvovirus is a particularly deadly disease among young puppies, causing gastrointestinal tract damage and dehydration as well as a cardiac syndrome in very young pups. It is spread by contact with an infected dog's blood, feces, or vomit. Symptoms include severe diarrhea, fever, vomiting, loss of appetite, and dehydration. Mouse parvovirus 1, however, causes no symptoms but can contaminate immunology experiments in biological research laboratories. Porcine parvovirus causes a reproductive disease in swine known as SMEDI, which stands for stillbirth, mummification, embryonic death, and infertility. Feline panleukopenia is common in kittens and causes fever, low white blood cell count, diarrhea, and death. Infection of the cat fetus and kittens less than two weeks old causes cerebellar hypoplasia. Mink enteritis virus is similar in effect to feline panleukopenia, except that it does not cause cerebellar hypoplasia. A different parvovirus causes Aleutian disease in minks and other mustelids, characterized by lymphadenopathy, splenomegaly, glomerulonephritis, anemia, and death. Goose parvovirus causes hepatitis, myocarditis, and death in goslings aged eight to thirty days. [1] The most accurate diagnosis of parvovirus is by ELISA. Dogs and cats can be vaccinated against parvovirus.

ONLY WHEN THEY BREATHE !!!  YES YES YES!!\n\nPlease see your doctor and your infection control nurse at work.  You will need to be treated and at least wear a mask while working.  I would advise you to take a leave of absence.  Hey, you don't want to spread this virus any farther to unsuspecting people, do you??? It could kill them...and you!   Please get treatment asap!

People cannot catch the canine parvo virus.  I nursed a puppy back to health from the parvo virus, it was awful. Its a 50/50 shot that the dog will survive it. They don't always die.

You mean porcine circovirus, right? Sorry, there is no cure for it. Some pigs can get over it with their own immune system but most carry it until the day they die. It induces diarrhea, so death can be soon. \n\nA similar virus is found in parrots, and makes all their feathers fall out. The circoviruses are related to the nanoviruses in plants, which also look like little circles of DNA.\n\nI hope the affected pig isn't a friend of yours? ;-)

Examples of common human diseases caused by viruses include the common cold, the flu, chickenpox and cold sores. Serious diseases such as Ebola, AIDS, bird flu and SARS are all also caused by viruses. The relative ability of viruses to cause disease is described in terms of virulence. Other diseases are under investigation as to whether they too have a virus as the causative agent, such as the possible connection between Human Herpesvirus Six (HHV6) and neurological diseases such as multiple sclerosis and chronic fatigue syndrome. Recently it was also shown that cervical cancer is partially caused by papillomavirus, representing evidence in humans of a link existing between cancer and an infective agent[4]. There is current controversy over whether the borna virus, previously thought of as causing neurological disease in horses, could be responsible for psychiatric illness in humans[5].\n\nViruses have many different mechanisms by which they produce disease in an organism, which largely depends on the species. Mechanisms at the cellular level primarily include cell lysis, the breaking open and subsequent death of the cell. In multicellular organisms, if enough cells die the whole organism will start to suffer the effects. Although many viruses result in the disruption of healthy homeostasis, resulting in disease, they may also exist relatively harmlessly within an organism. An example would include the ability of the herpes simplex virus, which cause coldsores, to remain in a dormant state within the human body.\n\nhope this helps

A virus is a microscopic parasite that infects cells in biological organisms. Viruses are obligate intracellular parasites; they can reproduce only by invading and controlling other cells as they lack the cellular machinery for self-reproduction. The term virus usually refers to those particles that infect eukaryotes (multi-celled organisms and many single-celled organisms), whilst the term bacteriophage or phage is used to describe those infecting prokaryotes (bacteria and bacteria-like organisms lacking a nucleus). Typically these particles carry a small amount of nucleic acid (either DNA or RNA, but not both) surrounded by some form of protective coat consisting of proteins, lipids, glycoproteins or a combination. Importantly, viral genomes code not only for the proteins needed to package its genetic material, but for proteins needed by the virus during its life cycle (the term "life cycle" is used loosely here—see #Living or non-living?).
