ABSTRACT
Streptococcus pneumoniae(S.pn) is an opportunity pathogenic bacteria,environmental factors play a key role in the pathogenicity of S.pn. It is important to study virulent gene in vivo. The S.pn suicide plasmid containing gfp reporter was constructed by fusing the genes pneumolysin and gfp,in which gfp is an excellent molecule probe in vivo. The plasmid was integrated to No.22 S.pn by homologous recombination. The recombinant S.pn was gained and evaluated in aspects of fluorescence excitation, biological character and physio-activity. The results showed it is efficient and available to report the expression of virulent genes in vivo and in vitro, which will provide a new easy method for evaluating and screening the virulent genes of S.pn in vivo.
