RESUMO

Objective To develop TaqMan real-time PCR assay for detection and identification of streptococcus pneumonia iso-lated from children CAP.Methods Based on the sequences of lytA gene,primers and probe were designed and the assay was optimized.Then 1 504 sputum samples were detected by culture and the developed assay with double-blind testing.Results The lower limit of detection in the developed real-time PCR assay was 18.75 cfu/PCR,and had no cross reaction.141 strep-tococcus pneumonia strains were detected from 1 504 samples and 140 were isolated by culture.The whole process just nee-ded 2.5 h.Conclusion The established assay is rapid,simple,high sensitivity and specificity.It is not only valuable for the i-dentification of streptococcus pneumonia,but also provide evidence for antibiotic therapy.
