The CD155 protein is otherwise known as the poliovirus receptor.
Poliovirus and West Nile virus sometimes can lead to AFM.
Cells could thenbe infected with the viruses that cause polio(poliovirus) and other diseases.
As recently as 30 years ago, wild poliovirus paralysed more than 350,000 children in more than 125 countries every year.
The most important step in eradication ofpolio is interruption of endemic transmission of poliovirus.
In most people with a healthy immune system, a poliovirus infection does not even generate symptoms.
In turn, rhinoviruses are part of a wider group known as enteroviruses,the most famous of which is poliovirus.
Poliovirus can survive and multiply within the blood and lymphatics for long periods of time, sometimes as long as 17 weeks.
In addition to protecting the virus's genetic material,the capsid proteins enable poliovirus to infect certain types of cells.
In immune individuals, IgA antibodies against poliovirus are present in the tonsils and gastrointestinal tract, and are able to block virus replication;
It reminds us of the importance of increasing immunizationcoverage to 95 percent of children to stop poliovirus transmission in the Philippines.”.
Today, despite a concerted global eradication campaign, poliovirus continues to affect children and adults in Afghanistan, Pakistan and some African countries(Nigeria).
Following on from the successful initiative to eradicate smallpox in 1980,a massive worldwide poliovirus vaccination program was agreed upon in 1988.
Although people carrying the poliovirus are most contagious seven to 10 days before and after signs and symptoms appear, they can spread the virus for weeks in their feces.
Their method was not widely adopted until the 1950s,when poliovirus was grown on a large scale for vaccine production.
Ultrasound has demonstrated its potential in the destruction of food-borne pathogens, like E. coli, Salmonellae, Ascaris, Giardia,Cryptosporidium cysts, and Poliovirus.
Because poliovirus can only survive for a short time in the environment(a few weeks at room temperature, and a few months at 0- 8 °C(32- 46 °F)), without a human host the virus dies out.[28].
Adults at risk include those who are traveling to parts of the world where polio still occurs orthose who care for people who may be excreting wild poliovirus.
At the end of 2013,60% of polio cases were the result of wild poliovirus spreading, with evidence suggesting that international travellers were a significant part of the exportation of the virus.
In areas with poor sanitation and sporadic or nonexistent immunization programs, the most vulnerable members of the population- pregnant women, the very young and those with weakened immune systems-are especially susceptible to poliovirus.
Enders, Thomas Weller and Frederick Robbins reported growth of poliovirus in cultured human embryonal cells, the first significant example of an animal virus grown outside of animals or chicken eggs.
Polio vaccination is also important in the development of herd immunity.[26] For polio to occur in a population,there needs to be an infecting organism(poliovirus), a susceptible human population, and a cycle of transmission.
Of the 3 strains of wild poliovirus(type 1, type 2, and type 3), wild poliovirus type 2 was eradicated in 1999, and no case of wild poliovirus type 3 has been found since the last reported case in Nigeria in November 2012.
Explaining the rationale behind their research endeavor, Dr. Gromeier says,"Knowing the steps that occur to generate an immune response will enable us to rationally decide whether andwhat other therapies make sense in combination with poliovirus to improve patient survival.".
Of the 3 strains of wild poliovirus(type 1, type 2, and type 3), wild poliovirus type 2 was eradicated in 1999 and case numbers of wild poliovirus type 3 are down to the lowest-ever levels with the no cases reported since a case reported by Nigeria in November 2012.
As Prof. Nair explains,"Not only is poliovirus killing tumor cells, it is also infecting the antigen-presenting cells, which allows them to function in such a way that they can now raise a T cell response that can recognize and infiltrate a tumor.".
In 1981, the poliovirus genome was published by two different teams of researchers: by Vincent Racaniello and David Baltimore at MIT[8] and by Naomi Kitamura and Eckard Wimmer at Stony Brook University.[9] Poliovirus is one of the most well-characterized viruses, and has become a useful model system for understanding the biology of RNA viruses.
Poliovirus is transmitted only through person-to-person contact and the transmission cycle of polio is from one infected person to another person susceptible to the disease, and so on.[2] If the vast majority of the population is immune to a particular agent, the ability of that pathogen to infect another host is reduced; the cycle of transmission is interrupted, and the pathogen cannot reproduce and dies out.
