Rabies Virus Anatomy

Rabies lyssavirus like many rhabdoviruses has an extremely wide host range in the wild it has been found infecting many mammalian species while in the laboratory it. Rabies virus rabv the etiological agent for the lethal disease of rabies is a deadly zoonotic pathogen.

The time it takes for the virus to reach the brain is known as the incubation period.

Rabies virus anatomy. The rabies virus first infects a nerve cell near the site of the bite and then spreads from nerve to nerve until it reaches the spinal cord and then the brain. The rna genome of lyssaviruses is 12 kilobases long non segmented and of negative polarity encoding five viral proteins 3 to 5. Drugs that inhibit polymerases of hcv and hiv 1 provide successful.

Rabies virus is rod or bullet shaped 75 x 180 nm. Rabies lyssavirus formerly rabies virus rabv is a neurotropic virus that causes rabies in humans and animals. Virus envelope contains glycosylated g protein spikes embedded in lipid membrane derived from the host cell.

Rhabdo viruses have a unique bullet shaped appearance measuring about 180 75 nm. Nucleoprotein n phosphoprotein p matrix protein m glycoprotein g and polymerase l. If someone were to be infected with rabies the first goal of the virus is to make it to the brain.

They have an envelope with prominent spikes on surface but not very variable in appearance. The time it takes for the virus to. The rabv glycoprotein rabv g is a key factor mediating virus entry and the major target of neutralizing antibodies.

The bullet shaped lyssavirus particle has 100 300 nm in length and 75 nm in diameter. The rabies virus first infects a nerve cell near the site of the bite and then spreads from nerve to nerve until it reaches the spinal cord and then the brain. During this period an infected person or animal doesn t show any symptoms and can t spread the virus.

The virus of rabies is somewhat like a bullet of a gun in shape and have a measurement of about one hundred eighty nanometers and the diameter of the cross sectional area about seventy five nano meters with one end being a rounded or conical one and other end being concave or planar. Rabies virus rabv and other viruses with single segment negative sense rna genomes have a multi functional polymerase protein l that carries out the various reactions required for transcription and replication. Many of these viruses are serious human pathogens and l is a potential target for antiviral therapeutics.

Rabies transmission can occur through the saliva of animals and less commonly through contact with human saliva. One end conical other planar concave. Spikes are made up of g protein that haem agglutinate rbcs.

This envelope doesn t cover the planar end.
