There are seven proteins in all that are encoded by the genome. Neither the 3′ nor the 5′ end is polyadenylated or … Read more

Cytomegalovirus (CMV) is a widespread virus whose manifestations in immunocompromised patients with congenital CMV disease range from asymptomatic to severe end-organ dysfunction. Human cytomegalovirus is a member of the herpesviruses, Herpesviridae, or human herpesvirus-5 (HHV-5) family of viruses. Infections with the human cytomegalovirus are frequently associated with the salivary ducts. An infection with CMV may … Read more

Rotavirus is a family of double-stranded RNA viruses belonging to the genus Reoviridae. Rotaviruses are the leading cause of diarrhea in neonates and young children. By the age of five, nearly every child in the world has been infected with rotavirus at least once.Immunity develops with each infection, reducing the severity of subsequent infections. Rarely … Read more

Among the diseases associated with this genus is gastroenteritis, a condition typically observed in mammals.Torovirus is the only genus in the monotypic Torovirinae subfamily.Torovirus is a monotypic taxon with a … Read more

A virus is a form of microscopic infectious agent that can only replicate within the cells of a living organism. Viruses are capable of infecting all forms of life, including animals, vegetation, and even bacteria. They are comprised of a minute piece of genetic material, either DNA or RNA, encased in a protein shell known … Read more

What is a Virus? Structure and Function of Viruses Properties of Viruses Classification of Viruses Classification of Viruses On the Basis of Genetic Material Present Viruses can be classified based on the type of genetic material they contain. There are two main types of genetic material that viruses can have: DNA (deoxyribonucleic acid) or RNA (ribonucleic … Read more

SARS-CoV is a type of coronavirus that caused a global outbreak of severe respiratory illness in 2002-2003. The virus was first identified in China and quickly spread to other countries, including Canada, where there was a significant outbreak. The symptoms of SARS-CoV include fever, cough, and difficulty breathing. In severe cases, the illness can progress … Read more

Coltivirus is a virus genus (of the family Reoviridae) that infects both vertebrates and invertebrates. It contains the agent that causes Colorado Lyme fever. The Colorado tick fever virus can lead to fever, shivers, headache, photophobia, myalgia, arthralgia, and fatigue. Children are especially susceptible to developing a hemorrhagic disease. Leukopenia containing both lymphocytes and neutrophils … Read more

Hanta Virus Structure of Hanta Virus Genome Structure of Hanta Virus Epidemiology of Hanta Virus Transmission of Hanta Virus Replication cycle of hantaviruses Pathogenesis of Hanta Virus The recognition of hantaviruses by macrophages (M) or dendritic cells (DCs) induces proinflammatory cytokines, which alter the phenotype of endothelial cells (ECs) from anti- to pro-adhesive. Pro-adhesive ECs … Read more
