Virus Essay

many things, including bacteria. When bacteria undergo infections from a virus that virus is called a bacteriophage. After a bacteriophage infects a bacteria it can create two different phases, the lytic or lysogenic cycles. During a lytic stage the bacteriophage causes death to the bacteria. When this happens on an agar plate covered in bacteria it creates a clear spot known as a plaque. Each plaque is created by one virus so from the number of plaques present it is possible to govern how many…

It is generally accepted that a virophage is a viral agent that infects other larger viruses. It is a dsDNA virus which utilizes the replication factories of other viruses to reproduce itself. Virophages are essentially parasitic in nature, much in the same way as traditional satellite viruses. It is not without controversy that distinctions between satellite viruses and virophages are described. The difference between the two often seem more semantic than factual and more supported by…

the origin of the CRISRP acronym. These CRISPR sequences are specific patterns of DNA sequences that are capable of being edited out of genes. Using the CRISPR system, bacteria are able to destroy the genome of invading viruses and thus prevent the virus from being able to replicate and survive in its host.…

Coronavirus comes from the family of coronaviridae, they are pathogens found in birds and mammals. Coronaviruses is a positive sense RNA virus and it was classified into four genera: Alphacoronavirus, Betacoronavirus, Gammacoronavirus, Betacoronavirus. There are many human types of the virus, for example, MERS-CoV, and SARS-CoV. SARS-CoV is a Severe acute respiratory syndrome. The Severe acute respiratory was found in 2003 when it first hit China and caused a big outbreak. Studies have shown…

are over the age of 60. It’s a viral infection that lays dormant and resurfaces during different times of a person’s life, especially when the immune system has been weakened. The official name of the virus is varicella-zoster, it affects the nerves of the skin, and this is also the same virus responsible for causing chickenpox. Although there is no cure for shingles, there are treatments to manage the pain. In most cases the person recovers with treatment, but the reinfection of shingles…

transmission is primarily via droplets from respiratory secretions and can spread via blood exposure. This is a common illness in the spring months. Etiology Erythema infectiousum is caused by Parvovirus B19. This is a non-enveloped single-stranded DNA virus belonging to the Parvoviridae family. Pathophysiology Viremia from Parvovirus B19 exposure usually occurs within 5-10 days, and the patient remains contagious approximately 5 days after viremia occurs. If an immunocompetent host is…

caused by the Epstein-Barr virus (EBV). It is characterized by sore throat, swollen glands and fatigue, which can last for weeks. It affects more adolescents and young adults and produces lifelong immunity against the virus. The integrated medicine addresses this disease with measures to combat the symptoms, with a nutritious diet to support the immune system, with massage and homeopathic remedies. Causes: The cause of mononucleosis is the virus of Epstein-Barr virus, which belongs to the…

A virus is a small infectious agent that replicates only inside the living cells of other organisms. Viruses might infect all types of life style ,from animals and plants to microorganisms. Air carries a lot of harmful viruses that caused the destruction of many cells. often the virus is enter of the body through the respiratory tract and is transmitted into the blood than spread to parts of the body. mumps virus has history, symptoms, and duration. First of all, mumps is an acute…

cholesterol and take advantage of the clustering of receptors there.1 Attachment to the lipid membrane is advantageous to the virus as endocytosis uses (PI)-3 kinase…

Rabies is caused by a virus of the same name that is shaped like a bullet; it is oblong on one end and flat or concave on the other. The the surface of the virus, expect the flat end, is covered in knobs of glycoprotein. The rabies virus is most commonly transmitted through the saliva of an infected animal. Though transmission has occurred through transplantation, this occurrences are extremely rare and the virus and subsequent disease are overwhelmingly transmitted by any warm blooded animal.…
