What is the causative agent of polio virus?
Poliovirus, the causative agent of polio (also known as poliomyelitis), is a serotype of the species Enterovirus C, in the family of Picornaviridae. Poliovirus is composed of an RNA genome and a protein capsid….

Is polio an RNA virus?
Poliovirus, the prototypical picornavirus and causative agent of poliomyelitis, is a nonenveloped virus with a single-stranded RNA genome of positive polarity. The virion consists of an icosahedral protein shell, composed of four capsid proteins (VP1, VP2, VP3, and VP4), which encapsidates the RNA genome (1).
What is poliovirus microbe?
Poliovirus is a rather small and simple virus. It is composed of a shell, or capsid, made of protein, as shown. The poliovirus capsid is about 30 nanometers in diameter. Within the capsid is the information to make new virus particles – a single molecule of ribonucleic acid, or RNA.
Is mumps RNA or DNA?
Mumps virus is a paramyxovirus in the same group as parainfluenza and Newcastle disease viruses, which produce antibodies that cross-react with mumps virus. The virus has a single-stranded RNA genome. The virus can be isolated or propagated in cultures of various human and monkey tissues and in embryonated eggs.
Was polio created in a lab?
Scientists from State University of New York at Stony Brook say they created infectious polio virus in the laboratory from scratch using publicly available genetic sequence information. Their research was published in the July 13 edition of Science.
How does polio affect motor neurons?
Poliomyelitis, often termed “polio,” is an acute infectious disease caused by an enterovirus which damages the anterior horn cells of the spinal cord and brainstem. Progress to lower motor neurone cell death leads to disruption of motor units and subsequent muscle weakness or complete paralysis.
