[Characteristics of the genome of poliovirus type 3 isolated from patients with poliomyelitis in Moldavia].

Twelve poliovirus isolates of serotype 3 from patients with paralytic poliomyelitis have been analyzed by oligonucleotide mapping of the viral genomes. All the studied strains were isolated from patients in different regions of the Moldavian SSR in 1982. The maps of all isolates are similar but they do not practically possess any large oligonucleotides characteristic of the vaccine strain of type 3 poliovirus.

[Characteristics of poliomyelitis viruses isolated from sewage].

Studies of the genetic markers of 39 (57.4%) strains of poliomyelitis virus type I isolated from sewage showed 7 of them to have genetic markers ret+40, Gu+, A+, Ag+ (Mahoney, Koñkov), 3 to be ret+40, Gu+, A+, Ag+ (Koñkov, Sabin), and 10 to be ret+40, Gu-, A-, Ag- (LSc 2ab). Among 20 (29.
