RABIES Abstract: Each year‚ approximately 55‚000 individuals worldwide die from an infection due to the rabies virus. Rabies is a life-threatening disease caused by an RNA virus that is usually transmitted to humans through bites from rabid animals. More recently‚ reports of transmission by means of organ transplantation have been reported. Since human rabies is nearly 100% fatal if prophylactic measures are not followed‚ an increased awareness of who should receive prophylaxis and

The Norovirus affects thousands of people every year according to the Centers for Disease Control (CDC). The Norovirus is a member of a category known as Calcivirus family. The virus is made up of four groups. The Norovirus is the most important virus to human pathogens. According to scientist the Calcivirus is difficult to study due to their

Viruses: Structure A virus particle‚ also known as a virion‚ is essentially a nucleic acid ( HYPERLINK "http://biology.about.com/od/geneticsglossary/g/DNA.htm"DNA or RNA) enclosed in a protein shell or coat. Viruses are extremely small‚ approximately 15 - 25 nanometers in diameter. Viruses: Genetic Material Viruses may have double-stranded DNA‚ double-stranded RNA‚ single-stranded DNA or single-stranded RNA. The type of genetic material found in a particular virus depends on the nature and function

Since smallpox disease was eradicated many human pox viruses have emerged .Monkeypox received most of the attention. Monkeypox is an infection zoonotic disease caused by the Monkeypox virus which it is a member of the family ’Poxviridiea. The disease is located mostly in Central and West Africa. The reason of why is the disease named as "Monkeypox" is because scientists discovered it first in a type of monkey in a laboratory in Copenhagen‚ Denmark in 1958. The scientists found that the clinical symptoms

The smallpox virus was once one of the most feared diseases in the world‚ and for good reason. Variola was a contagious virus that caused fever and painful‚ pus filled blisters all over the body. Victims had about a one fourth chance of survival‚ and survivors were covered with small‚ pitted scars and sometimes blinded or arthritic. Popping sporadically up in various civilizations‚ smallpox left a trail of destruction through two thousand plus years of mankind’s history. The story of smallpox is

Severe Acute Respiratory Syndrome is caused by a virus‚ not a certain type of bacteria. This virus belongs to a class of viruses called coronavirus. Since SARS was an outbreak caused by a virus that was previously unknown‚ scientist named the virus that causes SARS‚ SARS-associated coronavirus (SARS-CoV). World Health Organization (WHO) physician Dr. Carlo Urbani identified SARS as a new disease in 2003 when he diagnosed a severely ill 48-year old businessman who was traveling from the Guangdong

Life Cycle of Bacteriophage. Bacteriophage: Bacteria eating virus is called bacteriophage. Life Cycles: There are 2 types of lifecycles that occur in the bacteriophage: 1) Lytic Cycle 2) Lysogenic Cycle 1) Lytic Cycle: In lytic cycle‚ virus that is the bacteriophage causes lysis of the host cell. It is virulent phage. 2) Lysogenic Cycle: In lysogenic cycle‚ the bacteriophage does not cause lysis
