title: High and prolonged incidence of poliovirus strains during 1979 in North Bohemia. Isolations from unusual materials.
abstract: During March 1979 - February 1980, 53 strains of polioviruses types 2 and 3 were isolated from human specimens and from sewage samples, 52.8% of them on secondary monkey kidney cultures, 47.2% on diploid fibroblasts of human embryonic lung. Type 3 grew more often on monkey cell cultures, type 2 on human ones. Both types of poliovirus circulated in children and adult population during the whole year. Polioviruses were isolated from cerebrospinal fluids of 2 patients without any symptom of paralytic poliomyelitis: an intermediate type 3 in the course of a serologically proved tick-borne encephalitis, and a type 2, different in rct-marker from the vaccinal variant, in the course of a serologically proved parotitis with meningoencephalitis and pancreatitis.
