[A survey on enteroviruses-carrying status among healthy population in Changle and Wucheng counties of Shandong Province. Shandong Collaborative Group of Poliomyelitis].
Four-hundred and fourty-six faecal specimens sampled from healthy carriers between 0 and more than 20 year-old age groups in Changle and Wucheng counties of Shandong Province were collected from June to Sept. of 1991. From them, 142 (31.84%) isolates of enteroviruses were obtained. There was no significant difference in the enteroviruses isolation rate between Changle and Wucheng. No poliovirus was isolated. Among other enterovirus isolates, 85 were echoviruses, 6 coxsackieviruses, 9 enterovirus type 70 and 2 enterovirus type 71. Other 40 isolates were positive for cytopathogenic effect (CPE) in cell culture, but they could not be identified by antisera to poliovirus and enteroviruses. The results showed that the infection by non-polio enteroviruses which could cause polio-like paralysis should be paid attention in the poliomyelitis eradication program.
