The work presented here demonstrates the utility of a two-step algorithm for environmental poliovirus surveillance based on: preselection of sewage samples tested for the presence of enteroviral genetic material-RT-PCR assay and detection of infectious viruses by cell culture technique (L20B for polioviruses and RD for polio and other non-polio enteroviruses). RD and L20B cell lines were tested...

The 20-year, U.S. $4 billion-dollar international effort to eradicate wild polioviruses now includes monovalent oral poliovirus type 1 vaccine (mOPV1), which was first given to 40 million children in India in April 2005. As this vaccine is being introduced to eliminate some of the last poliovirus reservoirs, the Global Polio Eradication Initiative is planning for the eventual synchronized world...

Wallis, Craig (Baylor University, Houston, Texas) and Joseph L. Melnick. Thermal inactivation of poliovirus under anaerobic conditions. J. Bacteriol. 84:389-392. 1962.-Of the six strains of poliovirus tested (three antigenic types), none was stabilized at 50 C under anaerobic conditions. The previously reported stabilization of polioviruses using thioglycolate had been attributed to anaerobic c...
