Virus

Rabies is a serious disease caused by a virus and mainly affects animals. This virus belongs to the Rhabdoviridae family -- it's a “bullet shaped virus”. The virus is transmitted through a bite for humans which affects the central nervous system. It travels within the nerves and brain and may multiply rapidly. In the beginning symptoms may not show until maybe weeks and months go by. Rabies may cause pain, fatigue, headaches, fever and irritability often followed by hallucinations,seizures and…

shouldn't you do now? First of all, you need to know that a cold sore is caused by the herpes virus and that there's fluid in the blisters. A cold sore can be annoying and painful, but is hardly ever harmful. The herpes virus will remain forever in your body though, and can get reactivated at a later time. That's why you can get a cold sore over and over again. There isn't any treatment to get the virus out of your body. So, what are the do's and don'ts when you've got a cold sore? - Don't…

In recent years the field of virology has seen substantial growth as virus have now become a more widely researched subject. It was not too long ago relatively speaking that viruses were more or less an unknown entity, as many facts about viruses were unknown to the days researchers. Now however much more is known about what viruses are and how they work; more importantly it is known that viral agents are one of the leading causes of disease. Once it was established that they did in fact…

The influenza virus has become so deadly, due to its ability to mutate seasonally, through a process called reassortment. This involves the recombination of large genetic segments from several viral strains, which causes small genetic changes to be passed on to create a new type of daughter virus (4). Influenza viruses can do this by antigenic drift, which is when” dominant strains from the previous year have changed its surface structure enough to make the effectiveness of the flu vaccine…

A virus- a complex microscopic organism that possesses the ability to replicate inside the cells of a host. For centuries scientists have debated the topic of whether viruses are living organisms- or not. Viruses have been left in a “gray area”, becoming ignored in the study of evolution by scientists. When not in contact with a host, viruses tend to stray from the characteristics that define life. Characteristics such as the ability to respond to their environment, lack of cells, and the…

such as herpes varicella-zoster virus,simplex viruses,human herpesvirus,Epstein-Barr virus, Kaposi's sarcoma-associated herpesvirus and human cytomegalovirus. But there are over 130 herpesviruses affecting animals as well such as birds, fish, reptiles as well as much more.According to the CDC in the United States, about 1 out of every 6 people aged 14 to 49 years have genital herpes.The popularity of HSV-2 was nearly twice as high among women and was…

Lymphocytic Choriomeningitis virus (LCMV) belongs to the Old World arenavirus family of enveloped viruses (Buchmeier et al., 2007). LCMV in particular has served as model organism from many significant studies in the field of immunology such as the Nobel Prize winning study of the Major Histocompatibility Complex (MHC) by Zinkernagel and Doherty (1975). LCMV’s natural reservoirs are the common household rodents (Traub, 1936). Household mice have shown to attain persistent asymptomatic LCMV…

According to scientists the conventional wisdom of viruses says that about viruses, scientists say that viruses aren’t bigger than bacteria and that the majority have viruses have 10 or less genes. But organisms such as the meme virus, mega virus and the Pandora virus prove us wrong. In some cases, some of these controversies to the change of biological evolution is in heredity by accident, natural in nature or caused by mutation. Before 2003 there only two kinds of living things on earth which…

they are present and depend on another living organism/host. 8. (4 points) Discuss the differences between enveloped animal virus and naked animal virus in their ways of viral multiplication. Enveloped animal virus is composed of lipids, proteins, and carbohydrates (some have spikes arounds them). Naked animal virus is composed of capsomeres, but doesn’t contain an…
