The phenotype and localization of ts mutations in genomes of the influenza A/Victoria/30-ir (A/Vic/30-ir) and A/Hong Kong/17-ir (A/HK/17-ir) cold-adapted (ca) viruses were studied. Using the recombination analysis in chick embryo fibroblasts (CEF) we

The influenza A/Leningrad/134/47/57 (H2N2) (A/Len/47) cold-adapted virus expresses the ability to reproduce at 25 degrees C (the ca phenotype) and inability to reproduce at 40 degrees C (the ts phenotype). It was attenuated for mice. Reassortants of

As a result of serial passages (42 passages) at low temperatures (26 degrees--28 degrees C) of two influenza H1N1 and H3N2 virus strains stable cold-adapted (ca) variants were produced. Investigations of them showed the ca A/USSR/03/84 (H1N1) variant

An analysis of ts-mutations in the genomes of native and cold-adapted variants of influenza A/Leningrad/134/57 (H2N2) virus based on the use of fowl plague virus ts mutants was carried out. The recombination test was done by the conventional method i

Using mutants of fowl plague virus (FRV) which have single temperature-sensitive (ts) mutations in some genes, an analysis was carried out on reisolates from children of 3-6 years, vaccinated with a monovaccine from recombinant strains of influenza t

The ability of temperature variants of influenza A2 virus to produce plaques in chick embryo kidney tissue culture was studied at different temperatures. Definite differences in efficiency of plaque formation by cryophilic and thermophilic strains we

A high sensitivity of influenza virus to replication at a high temperature and a reduction of the temperature optimum of the neuraminidase activity are important genetic markers correlating with the degree of attenuation for the man. Cold-adapted var

The ts phenotype and location of ts mutations were studied in the genome of parent viruses and those obtained by recombination of cold-adapted strains A/Leningrad/134/17/57 or A/Leningrad/134/47/57 with epidemic H1N1 and H3N2 influenza A virus strain
