RESUMEN

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.

RESUMEN

OBJECTIVE To investigate the infection status and susceptibility of mycoplasma to 14 antibiotic agents. METHODS Mycoplasma was cultured and its susceptibility from 3577 patients with genitourinary tract infections were statistically analyzed. RESULTS The positive rate of mycoplasma was 43.9%.The positive rate of Ureaplasma urealyticum (Uu),Mycoplasma hominis (Mh ) and Uu+Mh were 33.4%,1.5% and 8.9%,respectively. The positive rate of Uu was significantly higher than that of Mh and Uu+Mh (P
