Study on The Relations between Premature、 Pneumonic Neonate and Mycoplasma Infection

To explore the relations between the premature 、 pneumonic neonate and the infections of Ureaplas-ma urealyticum (Uu)、 Mycoplasma pneumoniae ( Mpn)、 M. hominis ( Mh)、M. genitalium ( Mg) and M. fermentans (Mf) . The specimens of the throat swab were obtained in 151 health neonate 、 105 premature and 71 pneumonic neo-nate. These specimens were detected by nested polymerase chain reaction. The results showed that the positive rates of Uu、Mpn and Mh in health neonate were 8.6% 、3.3% and 2.0% ; those of Uu、Mpn、Mh and Mg in premature were 44.8%、21.9%、10.% and 4.8% (P all 3.0);those of Uu and Mpn in pneumonic neonate were 42.3% and 25.4% (P all3.0).These results indicated that mycoplasma infection might be the important cause of the premature、pneumonic neonate.
