ZIKA VIRUS Zika virus is center of an ongoing pandemic and public health emergency with serious medical and economic consequences. (Plourde and Bloch, 2016). Zika virus belongs to the family of flavivirus which includes other mosquitoborn viruses like chikungunya virus, dengue virus, yellow fever virus and West Nile virus (Plourde and Bloch, 2016). Zika virus is transmitted to people primarily through the bite of an infected Aedes species mosquito (Ae. aegypti and Ae. albopictus), other Aedes…

West Nile Virus Microbiology BIOL-2420-031 Elizabeth Carter March 30, 2017 West Nile Virus One of the most talked about and publicized viruses in the world today is the West Nile Virus. Named for the West Nile district of Uganda, West Nile Virus was first isolated in a woman in the West Nile district of Uganda in 1937 (World Health Organization, 2011). Although well known today, prior to 1999 the West Nile Virus was virtually unheard of in the United States. However, in New York City…

1. Description of the Disease: West Nile virus (10 points) 2. What causes it? (WNV) is found by mosquito bites. Mosquitoes become infected when they feed on infected birds Scientific Name: Flavivirus (5 points) 3. Where is it found? All 48 lower states. not reported cases are Alaska and Hawaii. commonly found in Africa, Europe, the Middle East, North America and West Asia (10 points) 4. How is it spread? Arthropod-borne virus. West Nile virus has been spread through blood transfusions, organ…

dormant until another time. A common example of this type of virus is the Varicella Zoster virus. This is the virus that causes chicken pox in children and young adults, but is also the culprit for shingles in elder adults. Varicella Virus has the ability to “hide out” from the body’s immune system until the time is right to strike. The Varicella Zoster Virus is a part of the Herpesvirdae family[1]. Characteristics of this class of virus are a primary infection…

West Nile Virus is a virus that affects the brain and body. Many victims are infected with the West Nile Virus don’t know that they have it because there is no symptoms. Because there are no symptoms, it usually evolves to West Nile Fever or severe West Nile Disease. The people who develop West Nile Fever have symptoms of fever, headache, tiredness, body aches, nausea, vomiting, and occasionally a skin rash and swollen lymph glands (West nile virus, 2011). When people develop severe…

Epstein - Barr virus or, Human herpesvirus 4, is the virus that causes infectious mononucleosis, and contains double-stranded DNA. This virus is species specific in that it only infects humans. The Epstein-Barr virus was discovered in 1964 when Michael Anthony Epstein and Yvonne Barr found it in a Burkitt lymphoma cell line. In 1968, they then linked the virus to the disease infectious mononucleosis. Once the host is infected with the virus it stays in the host for the remainder of the host’s…

birds can be asymptomatic carriers spreading the virus, while domestic birds usually sicken and die in just a few days after contracting the virus. AI has been identified in over 100 different species of wild birds worldwide, with the majority of these being waterfowl (Center for Disease Control and Prevention). OVERVIEW I was unable to find a clear date for the imminence of AI in birds; however, the first human infection of highly pathogenic AI virus was detected in 1997 during a poultry…

It has many functions such as delivering the genome, interactions of virus with cells, and includes protection of the genome from nucleolytic enzymes. The virion extended tail fibres and hits the bacterium and the bacteriophage is triggered and starts hosting the virus. The structure of a T-even bacteriophage consists of a head in an icosahedral shape, 20 sides, which is called the capsid. Attached to the capsid is…

the export of RNPs by producing nuclear export signals and binding with RNP to form a complex that can be exported (Paterson and Fodor, 2012). M proteins also plays crucial role when the new virus buds off. It blocks the nuclear pores to stop re-entry of the newly formed RNAs and allows assembly of the new virus. M proteins can bind the phospholipid tail of the cell membrane with the viral envelope of the glycoproteins around the encapsidated RNA and bud off the host cell (Figure 1)…

Chickenpox is a contagious infection that is caused by the varicella-zoster virus. Everybody can be infected by the varicella-zoster virus but it effects younger children’s more. Chickenpox can last up to 15 days Symptoms: A itchy rash that causes blisters with fluid, and once the blister erupts it causes to develop a crust. Also fever, feeling tired, headache, and anorexia is common. Treatment: The body has to fight the virus on its own. For the symptoms special creams to prevent from itching,…
