The Morphogenesis of Poliovirus
1972Poliovirus is one of the simplest and most extensively studied animal viruses. Yet, in spite of the voluminous literature, many basic and important questions concerning its morphogenesis remain unanswered. For example, what mechanisms insure that the progeny virus retain the precise structural features of the infecting particle ? How does the viral RNA

Composition of poliovirus fibrils
Archiv f�r die gesamte Virusforschung, 1973Poliovirus radioactively labeled in its RNA and protein components was treated with various combinations of temperature, pH and sodium dodecyl sulphate (SDS) or with concentrated urea in order to induce the formation of fibrils. These were purified and their labeling was studied. In all cases the fibrils contained RNA and protein precursors.

Poliovirus Infection in Guatemala
The American Journal of Tropical Medicine and Hygiene, 1960Summary The objective of the present study was to determine the frequency of poliovirus infection in Guatemala, primarily the inapparent infections occurring there. Sero-immunity, as indicated by serum neutralization tests in HeLa cell cultures, was demonstrated to all three poliovirus types.

Photodynamic inactivation of poliovirus
Virology, 1963Abstract Poliovirus, as usually found in fluids of infected cultures, cannot be inactivated photodynamically in the presence of heterotricyclic dyes. However, if the mature virus is freed of extraneous organic material, dyes can attach to the virus and render it light-sensitive.

Use of inactivated poliovirus vaccine for poliovirus outbreak response
The Lancet Infectious DiseasesWith continued wild poliovirus transmission in Afghanistan and Pakistan and circulating vaccine-derived poliovirus in certain countries, there exists an ongoing risk of importation of polioviruses into other countries, including those that have been polio-free for decades.

Inactivated poliovirus vaccine and the final stages of poliovirus eradication
Vaccine, 2001The use of the inactivated poliovirus vaccine (IPV) will increase before and probably also after the global eradication of the wild type poliovirus. Before eradication, the switch from the use of oral poliovirus vaccine (OPV) to IPV has been due to the better safety record of IPV. Introduction of IPV in the regular immunisation schedules is made easier

Stabilization of poliovirus by cystine
Virology, 1958Abstract Incubation of a heat-sensitive strain of (t + ) poliovirus with l -cystine produces a considerable enhancement of its thermal stability at temperatures below 50°. The effect is specific in that d -cystine and a number of other compounds are ineffective.
