Virus

For the initial entry of the virus, the ephrinB2 domain is necessary. Once entered through micropinocytosis, protease cathespin L activates the virus (12). Nipah Virus can replicate very easily in human lung fibroblasts. It can infect the surrounding cells by either cell-to-cell spread or through release of infectious particles. When monocytes get infected, they can transmigrate through the blood brain barrier to infect the brain. This could be plausible if the monocytes were inefficient in…

mining company was destroying the trees. The bat flew into a slaughterhouse dropping the infected banana onto the floor that the pig consumed. The virus than found a viable host, the pig while the chef with bare hands stuffed the pigs mouth, he rubbed the virus onto his hands, passing it to Beth via hand shaking. Beth could have become ill with the virus from touching her face, food to mouth or rubbing her eyes from being “jet lagged.” The transmission agent; “Vehicle-borne transmission…

Viruses are infective agents that are unable to support themselves and rely on other hosts for survival. Although they are not a living thing, viruses are able to infect humans, plants, bacterias etc. Depending on the type of virus, they target a specific organ or type of cells and inject their DNA or RNA in the cell to reorganize the genetic material of the cell. The cell then follows the new DNA instruction and produces more viral viruses. The adenoviridae, better known as adenoviruses, are a…

What is a Virus? Virus - A virus is a tiny organism that can reproduce inside the cells of an organism. Most viruses are microscopic they are only observable through an optical microscope. Viruses can infect all types of organisms ranging from plant to animals as well as bacteria and other archaea. There are around 5000 different types of viruses described at the current time, however, it is thought that there are millions different viruses of distinct types. Viruses are seen in every…

influenza virus was infecting its hosts long before the discovery of viruses in the late 1800’s. The longevity of the virus can be attributed to its ability to quickly mutate its genome, which consists of only eight negative-sense RNA segments. These small mutations allow the virus to rapidly evolve. In fact, approximately every twenty to thirty years the virus evolves into a “super virus” capable of causing significant pandemics (Webster, 2014). The influenza A virus is the envelope virus…

a. Introduction Lujo Hemorrhagic Fever is caused by a bi-segmented negative RNA virus that is one of several viruses known to cause viral hemorrhagic fever. The Lujo virus is part of the Arenaviridae family, which consist of several viruses categorized into two groups. The Lujo virus is categorized in the “Old World” group, which signifies that the virus in question was found in the Eastern Hemisphere, specifically the continent of Africa. The majority of the arenaviruses categorized in the…

reactivate and the virus starts transcribing its genes again. It is important to state that once a person has been infected with Herpes Simplex Virus, this virus will remain latent in the hosts body for years and will eventually reactivate periodically causing the disease. Different stimuli can cause the virus to leave its dormant state such as, fever, trauma, emotional stress, sunlight, and menstruation. Herpes Simplex Virus can be transmitted into the host body through direct contact between…

caused by the Epstein-Barr virus. It affects mostly teenagers and young adults and leads to fatigue, skin rashes and swollen lymph nodes. Currently, there are no specific cures to eliminate glandular fever from its host, however, treatments are available to fight the symptoms and the most reliable cure currently is for body’s immune system to combat the virus. Glandular fever or mononucleosis is a viral infection caused by the “Epstein-Barr” (EBV). The Epstein-Barr virus is composed of a double…

Feline Immunodeficiency VirusThe Feline Immunodeficiency Virus (FIV) was first isolated from cats in 1986 and wasdiscovered due to an outbreak of FIV infected cats housed together in several pens (Pederson112). FIV belongs to the family Retroviridae, the subfamily Orthoretrovirinae, and the genusLentivirus (Taniwaki et al. 551-552). Being that FIV is a lentivirus, this means that it’s a “slowvirus” with long incubation periods that could last for years (CFHC). FIV is present worldwideand “in the…

Chickenpox’s causative microbe name is known as Varicella-Zoster virus. In the medical field its terminology is known as Varicella. Chickenpox is well acknowledged as one of the numerous childhood diseases that produces skin lesions (Bauman, 2014). Varicella is highly contagious because the virus can spread in the air when an infected person coughs or sneezes. It can also be spread by touching or even breathing in the virus from the varicella lesions (Clinical Overview, 2013). Varicella is…
