Multiplex real time polymerase chain reaction was done to detect the genes encoding the pneumococcal pneumolysin using primers shown in Table 2.
The objective of present study is to gain more knowledge about the function of important domain of the toxin pneumolysin. This study aims to analyze the structural and functional features of pneumolysin and to investigate the residues involved in its pathogenicity.The major virulence factor of this bacterium is a protein, pneumolysin, which is the member of thiol-activated cytolysins.

Streptococcus pneumoniae, which secretes pneumolysin that help them to act on the respiratory system of various age groups particularly of children that may be lethal to cause death [9].
Primers ply-894 and ply-974 were described by Corless et al., (11) targeting a specific region of the pneumococcus pneumolysin gene (ply) amplifying a 80 bp amplicon.
The pathogenesis of increased susceptibility to pneumococcal infection following RSV infection in mice-model studies has been attributed to RSV G glycoprotein-binding penicillin-binding protein 1a increasing pneumococcal virulence owing to up-regulation of virulence genes, pneumococcal toxin and pneumolysin. This could lead to an increase in the inflammatory response and bacterial adherence to human ciliated epithelial cultures.
