switched hosts to humans. By studying theses effects on viruses‚ it helps us to better understand viruses and how to control future epidemics in the world. The latest types of viruses infecting humans today are the enzootic and epizootic viruses; these viruses come from the transmission of animals to humans. Another virus‚ Human immunodeficiency virus (HIV)‚

The Filoviridae family of viruses is where the Ebola virus belongs. The virus is distinguished by long filamentous structure which can present as straight‚ branched‚ and circular or a folded strand with a uniform diameter of approximately 80 nm but can be many different lengths. Liver cells‚ neutrophils‚ endothelial cells and macrophages are specifically targeted by the virus. Large quantities of cytokines are created by infected cells which solicits a large response from the immune system and interrupts

first time in human history‚ today we live in the era‚ for most of us‚ where everything is at our fingertips. Food‚ water‚ house‚ transportation‚ technology‚ and well‚ you name it. As of May 2017‚ current World Population is 7.5 billion. I remember my 6th grade year when it was 7 billion. We all come into contact easily. Walking down the street‚ work‚ school‚ park‚ modes of transportation and etc… We touch everything and without realizing harmful little things lurking naked to the human eye‚ from which

Ever since the virus got out‚ our town has be quarantined for months. The virus is deadly; If you catch it you won’t notice it at first‚ but you’ll slowly start to catch a fever. Your skin will be hot as fire. Welts will begin to form all over your body and you’ll begin to bleed from every pore. It’s sickening to watch and it’s a sight you’ll never forget for as long as you live; however long that may be. My mother and sister have contracted it. I can tell from their high fever and even though they’re

Type A Influenza Virus Essay Influenza: a virus that replicates‚ mutates‚ spreads among species‚ and the cause of the recent H1N1 scare is definitely an apparent danger to humans today. Type A influenza is an RNA virus that ‘reproduces’ through replication. The virus particles are surrounded by hemagglutinin (HA) and neuraminidase (NA) – both are structural glycoproteins attached to the virus’s outside lipid bi-layer. HA serves its function in helping the virus to bind to the sialic acid receptors

The innovation of the cowpox vaccine led to the eradication of the smallpox virus and is the biggest contribution to biomedical science and human health(1).

Abstract Global outbreaks of human influenza occur from influenza A viruses with novel Hemagglutinin (HA) molecules to which humans have no immunity. So understanding of the origin and evolution of HA genes is of particular importance. Host-origin classification based on the two outer proteins Host classification based on the HA protein achieved accuracies between 91.2% and 100% using KNN and random forest. While host classification based on the NA protein achieved accuracies

Lecture 2- overview of the virus 1. The first step- the virus binds to a receptor-->entry and uncoating--> early gene expression-->replication of viral genome-->late gene expression->assembly of viral progeny-->exit 2. Concept 2.1- Virus entry is a multistep process with the ultimate goal of delivering viral genome (payload) into the cells. A. Binding to surface receptors- - a viral receptor is cell surface molecule‚ likely a transmembrane protein - a virus may need multiple receptors

Imagine going on vacation to a foreign country and when you come home you are horribly sick. Your head hurts‚ you have a high fever‚ and you start vomiting. Chances are that you may have contracted the Ebola virus. Ebola was first discovered in the village of Yambuku(1) near the Ebola River in Zaire. Since its discovery‚ there have been four outbreaks of this disease. There are three known strains‚ of variations of ebola. There is no known cure for this disease(2).Ebola has become one of the

The hepatitis C virus (HCV) is a single-strand and positive-sense RNA virus of the Hepacivirus genus in the Flaviviridae family (1). According to the organization of the HCV genome‚ the virus is divided into 7 genotypes and more than 60 subtypes. The seven genotypes of this virus are seen in all over the world. It is known that HCV genotype one and four are hard to treat‚ while genotype 2 and 3 have more comfortable treatment. Thus‚ identification of HCV genotype in infected patients is essential
