The Hanta Virus The hanta virus is not a new foe to humanity. This mysterious and sometimes fatal disease has plagued humanity for over 1000 years. This virus, most likely originating in China over 1000 years ago, is transmitted by human contact with mice. Only relatively recently has the hanta virus captured the attention of the United States. Although the hanta virus has been known for such a long time, there is little known about the virus. In the United States most cases are found in the southwestern
are any RNA disease/virus that belongs to the family Retrofired. The virus was discovered in 1971 by Howard Temin and David Baltimore. 8uRetroviruses are uniquely shaped viruses, confusing features and overwhelming morbidity of the disease they cause. The genome of Retroviruses consists of RNA into DNA. Retrovirus have an outer envelope, which came from the plasma membrane of the host. There is an envelope protein in the lipid bilayer, actually many copies of this. The virus has a capsid, which
influenza subtyupes and function critical for viral fusion. Therefore, characterizing permitted evolutionary routes of the virus over the course of F10-type immune selection may serve as templates for the design of universal influenza vaccine and treatment strategies against all types of influenza viruses including those emergent pandemic strains. Selection of VN/04 (H5N1) or A/PR/8 virus escape mutants with F10 antibody was performed in MDCK cells under conditio... ... middle of paper ... ...nd effects
Polio Virus Introduction The polio virus which causes poliomyelitis in humans is an enterovirus which belongs to the picornavirus (small, RNA) family. Polio virus is rapid, acid-resistant, stable, highly tissue specific and consists of a single-stranded, positive RNA. Polio virus is able to reside in the throat or intestinal tract of humans. Poliomyelitis is a highly contagious infectious disease which has three strains, poliovirus 1 (PV1), PV2 and PV3. Polio virus, although rare in developed
Introduction Potato virus X (PVX) is a plant RNA virus. Its infection cycle includes invasion of the host plant, RNA replication, translation of viral proteins, cell-to-cell movement and release of new virions. Upon infection, PVX releases its plus-strand RNA genome from the virion and produces a viral replicase using host translation machinery. The replicase synthesizes minus-strand RNA. Subsequently new plus-strand genomic RNA (gRNA) and subgenomic RNAs (sgRNAs) are produced. Movement and coat
Mumps Virus Mumps is a paramyxovirus that is closely related to the parainfluenza virus. Its symptoms were first described in the 5th century BC, and it was a very common childhood affliction until the last several decades. It was identified as a virus in 1934, and an effective vaccine was developed in 1967. Mumps is acquired by aerosol, necessitating close human interaction for spread. Human beings are the only known reservoir for mumps virus, and there is only one serotype. Multiplication
Marburg virus belongs to the genus Marburgvirus in the family Filoviridae, and causes a grave hemorrhagic fever, known as Marburg hemorrhagic fever (MHF), in twain humans and nonhuman primates. Basic Safety measures for medical personnel and others who are taking care of presumed individuals who may be contaminated with Marburg disease. Marburg Virus, Akin to the more widely known Ebola hemorrhagic fever, MHF is portrayed by systemic viral replication, lowering the body’s normal immune response to
Virus Among the Navajo Medical investigators, such as myself, have not given a great deal of attention to the "medical" traditions of indigenous groups in the past. But the outcomes of the recent investigation that took place in "The Four Corners" area exemplify our need to consider age-old notions right along with the ecological history of the region in question. A few months ago, the New Mexico Department of Health notified my department (Office of Medical Investigations) that three young
1. 8. Dengue Virus The causative agent of the dengue disease is the dengue virus (DENV), a group of four flaviviruses that are closely related but antigenically distinct. They are hypothesised to have evolved independently from ancestral sylvatic viruses between 100-1,500 years ago (Wang et al., 2000). The four groups are known as serotypes and denoted as dengue virus type 1 (DENV-1), dengue virus type 2 (DENV-2), dengue virus type 3 (DENV-3) and dengue virus type 4 (DENV-4). 1. 8. 1.

PANLEUKOPENIA VIRUS Virus Classification: Order: Mononegavirales Family: Parvoviridae Subfamily: Parvovirinae Genus: Parvovirus Species: Feline panleukopenia virus Also called feline infectious eneritis, feline “distemper”, and feline ataxia or incoordination. Examples of other viruses belonging to the same genus as Feline panleukopenia virus include Canine parvovirus type 2, Porcine parvovirus, Mink enteritis virus, and Raccoon enteritis virus. Virus Structure: Feline
death. [7, 8] This disease was isolated by scientists and later classified as the Hendra virus. The Hendra virus (HeV), previously unknown, is now classified under the family Paramyxoviridae, genus Henipavirus along with its sister viruses the Nipah Virus and Cedar virus.[7, 9] HeV has the capability of causing fatal diseases in several animal species including humans.[1] The primary host of the Hendra virus was identified as the flying fox species from the genus Pteropus[1,2,3] that resides and
Caught A Virus? If you've let your guard down--or even if you haven't--it can be hard to tell if your PC is infected. Here's what to do if you suspect the worst. Heard this one before? You must run antivirus software and keep it up to date or else your PC will get infected, you'll lose all your data, and you'll incur the wrath of every e-mail buddy you unknowingly infect because of your carelessness. You know they're right. Yet for one reason or another, you're not running antivirus software
HISTORY Congo virus is also known as crimean-congo virus. The virus was named as Crimean–congo on the basis of location where it was first found. The virus was first discovered in 1944 in South East Asia and Europe during the outbreak with hemorrhage fever characterized by bleeding and fever that can be fatal. Disease was first diagnosed in three peoples showing the same symptoms but only one of them survived. Later on, multiple copies of RNA genome of congo virus was found in the serum of
The Marburg Virus Why did I decide to choose to study Kongolese Art? Why didn't I just decide to study something safe, like British watercolours? If I had, I would have never had to spend the past three days in isolation in a hospital in Germany to ensure that I wasn't harbouring the Marburg virus. My experience with Marburg started about three weeks ago in early April--April 1, 2005 to be exact. I had been in Angola for the past seven weeks conducting an intense study of Kongolese art in
Jordan Richards BIOB 425 Paper #1 Assembly of endocytic machinery around individual influenza viruses during viral entry The purpose of this paper was to determine the entry method of influenza by tracking an individual influenza virus and endocytic structures in living cells. The main focus of entry was clathrin-mediated pathways and clathrin- and caveolin- independent pathways. These pathways were further researched to understand the development and use of clathrin-coated pits (CCP) and clathrin-coated
The Ebola Virus is an extremely deadly virus found in Africa. There have been multiple outbreaks across Africa and one in the United States. The Ebola virus basically causes uncontrollable bleeding externally and internally. Then your organs become liquefied. This usually results in death(www.encyclopedia.com). The following report contains info on the characteristics and history of the Ebola Virus. After being infected with the Ebola virus it takes 2-21 days to take effect. It depends if you
The Ebola Haemorrahagic Fever, or Ebola for short, was first recognized as a virus in 1967. The first breakout that caused the Ebola virus to be recognized was in Zaire with 318 people infected and 280 killed. There are five subtypes of the Ebola virus, but only four of them affect humans. There are the Ebola-Zaire, Ebola-Sudan, Ebola-Ivory Coast and the Ebola-Bundibugyo. The fifth one, the Ebola-Reston, only affects nonhuman primates. The Ebola-Zaire was recognized on August 26, 1976 with a 44 year
Orthopoxvirus variola is the virus responsible for the well-known smallpox disease. It belongs to the Poxviridae family which is further split into the subfamilies Entomopoxivirinae which only affects insects, and Chordopoxivirinae which infects vertebrae (Hughes). It is in group one of the Baltimore Classification since it possesses double-stranded DNA. This group also includes viruses in the Herpesviridae family, certain bacteriophages, as well as the mimivirus. The linear genome consists of approximately

One will grasp preventive or protective methods from what can end up becoming a deadly virus. One will comprehend governmental findings and investigations. The signs and symptoms will become more easily recognizable. Knowledge will be gained of treatments used to combat the virus to ensure little to no fatalities
We live in a time rapidly changing of the climate and the environment. Some viruses had become the most dangerous nonliving organisms in the world. They are small but their impacts are very deadfall, since most of virus diseases have no cure. However, one type of these dangerous diseases are the emerging viruses, which come by surprise, kill as much people as it can before it goes back to its hibernation. Emerging viral viruses are viruses that contain RNA as their genetic materials, therefore they
