In 1958 Poliomyelitis Institute in Moscow and Institute of Experimental Medicine in St. Petersburg received from A. Sabin the attenuated strains of poliomyelitis virus. The characteristics of the strains were thoroughly studied by A. A. Smorodintsev and coworkers. They found that the virulence of the strains fluctuated slightly in 10 consecutive passages through the intestine of the non-immune ...

Further evidence for the widespread occurrence of Coxsackie or C virus is presented in this paper. This virus is characterized by paralysis and myositis produced in infant mice. An epidemic of mild illnesses diagnosed as "non-paralytic poliomyelitis" and as "summer grippe" occurred during the summer of 1947 in Akron and Cincinnati, Ohio. From the pooled feces of such patients both poliomyelitis...
1. Bilateral olfactory neurectomy did not prevent experimental poliomyelitis on intravenous or intracutaneous inoculation. 2. Various operative procedures increased the susceptibility of monkeys to infection with experimental poliomyelitis.
OBJECTIVE On 29 October 2000 poliomyelitis was officially declared to have been eradicated from the Western Pacific Region. This article describes the results of surveillance for cases of acute flaccid paralysis (AFP) in China during the final phase of the eradication effort. METHODS We conducted hospital-based active surveillance in high-risk areas for poliomyelitis in 5 provinces of souther...
Mycoplasma contaminants can be considered important not only for their roles as pathogens but also they may indicate that insufficient care has been taken during vaccine manufacture or quality control. The purpose of this study was to test the poliomyelitis vaccines for Mycoplasma by culture and polymerase chain reaction (PCR) methods. During 2008 to 2009, a total of 47 lots of oral poliomyelit...
In 1988 the World Health Assembly set the goal of global poliomyelitis eradication by the year 2000. Substantial progress has been made, and 143 countries reported no poliomyelitis cases associated with the wild virus in 1993. This article reviews the immunological considerations relevant to interrupting the transmission of wild polioviruses with vaccines. Although serum immunity prevents polio...
Background and Objectives: : According to the global strategy for polio eradication, targeted surveillance of the disease is one of the main tasks of the health system. The purpose of this study was to review the status and surveillance of poliomyelitis/acute flaccid paralysis (AFP) in Iran. Methods: The present study was a review on the processes, structures and achievements of the poliomy...
BACKGROUND Poliomyelitis has historically been endemic in China and has been considered an important cause of disability and death. METHODS We reviewed strategies and measures of poliomyelitis control and eradication from 1953 to 2012. Data from notifiable disease and routine immunization reporting systems and acute flaccid paralysis (AFP) surveillance were analyzed. RESULTS About 20 000 po...
