Marburg virus

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…

As explained by the New World Encyclopedia, the lytic cycle is the life cycle of a virus in which “the virus that has entered a cell takes over the cell 's replication mechanism, makes viral DNA and viral proteins, and then lyses (breaks open) the cell, allowing the newly produced viruses to leave the now disintegrated host cell to infect other…

Encephalitis as defined as simply as possible is; inflammation of the brain. That four-word definition packs a lot of potentially horrific lifelong challenges for those whom suffer from it unfortunately. Inflammation is a response of our immune systems to both infection and or invasion. With encephalitis the inflammation happening in our brain’s makes the tissue become inflamed and swollen. This combination leads to headaches and fevers in addition to a wide range of other symptoms that can be…

"We used to think that our fate was in our stars, but now we know that, in large measure, our fate is in our genes, " - James Watson. (Rocholl, 1996) Gene Therapy is the key to unlocking our fate that is deeply hidden within our genes. As viruses get stronger and new diseases are discovered, we need one treatment that can cure all of that. Scientists hope that this treatment will be Gene Therapy. It’s a brilliant idea, however there are many risks, regulations and ethical issues involved. It’s…

been concerned with bacteria resistance to antibiotics”. With this evidence, it is clear that bacteria are evolving, and evolution exists on some scale. This is the reason there is a new flu vaccine every year; it is because different strains of the virus are becoming more prevalent and a new vaccine is needed to prevent it from infecting its host. Evolution is supported by examples such as this because it is obvious populations of bacteria are evolving, becoming resistant to new vaccines, and…

Parasitism is one of several classes of symbiosis. A parasitic relationship is a non- mutual relationship between two organisms. One organism, the parasite, lives off another organism, the host. The parasite typically attacks one host and does not kill the host. However, a parasitoid is another parasitic relationship where there is one host and the host is always killed. Sacculina is a genus of parasitic rhizocephalan barnacles that infect and castrate crabs. This genus was first described by…

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…

called urticaria are red welts or bumps that appear on the body of the patient. The condition is called acute urticaria if it lasts not more than six weeks, and chronic urticaria if it continues beyond six weeks. Acute urticaria is most commonly caused by exposure to an allergen or by an infection. The cause of chronic urticaria is largely unknown yet until nowadays. Contact dermatitis is a kind of reaction that appears when the skin comes in contact with an allergen or an irritant. Symptoms can…

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…

DESCRIPTION The olecranon is the pointy bone at the tip of the elbow. The Bursae are thin, slippery sacs located throughout the body that act as cushions between bones and soft tissues. They contain a small amount of lubricating fluid that allows the skin to move freely over the underlying bone. However, the bursa can become irritated or inflamed and fill with extra fluid. When this happens, a painful swelling develops at the back of the elbow. This swelling is olecranon bursitis. CAUSE •…
