Biological characteristics of influenza virus strains isolated at the Government of India Influenza Centre, Coonoor, during 1950-60.
The isolation of influenza virus strains of different types from the same or closely adjacent localities in the Nilgiris district of India in 1959-60 led the authors to investigate the biological characteristics of those strains and to compare them with strains isolated in previous years at the Government of India Influenza Centre at Coonoor. The haemagglutination with erythrocytes of different animal species, the sensitivity to inhibitors in normal sera, the effect of heat and the effect of ether are reported on in this paper.
